6  Program SIMO : Simultaneous Interface Monitoring


6.1 Introduction

The program SIMO is the transmit and receive module. It controls the receipt and transmission of the telegrams simultaneously on four channels. The parameterization of the single channels, i.e. the allocation with protocol type, transmission mode, data format etc. is done in the program LIAN.

 

 

6.1.1 Screen Output

The screen is divided horizontally into four windows which represent, from top to bottom, the four channels. Each window is again divided into an output window for the received data and a smaller status window displaying the channel parameterization. If the program SIMO is started the number of the serial interfaces is determined automatically and the screen is divided accordingly.

Information in the window title :

| Cn ---xxxxxxxxxx--- SCN  ON |

Cn
xxxxxxxxxxx
SCN ON / OFF

Channel number :  n = 1...4
Data format
Screen on/ off

Information within a window :

errors
records
cmt line

number of the errors that have occurred
number of received records
a free commentary for the channel

 

6.1.2 Status line

The details in square brackets represent the possible settings

6.1.3 Recording of received data

The received data of all four channels are first stored in binary format in the so-called archive file. The name of this file and the directory in which it is to be created can be determined in the program LIAN ( menu item <Settings | ArchivFileName> ). The maximum size of this file can be defined in the program LIAN ( menu item <Settings | ArchivSize> ) as between 1 and 32 MB. If the amount of the received data exceeds this size, recording is continued at the beginning of the file. Before being output to screen, the data are translated into plaintext, for which the format can be set ( see menu item <Settings | Format> ).

 

6.1.4 Protocol file

If there are disturbances during transmission, they are recorded in the protocol file. The name of this file and the directory in which it is to be created can be defined in the program LIAN ( menu item <Settings | ProtocolFileName> ).

Note :

The entry is generally limited to the errors which have occurred. An exception from this is the time measurement. In this case the received data are recorded without restriction.

The entries have the following format :

The error message starts with a header, e.g. :

3============[1 - Sinaut PCM - *F: TimeOut !]=============

or

1--------------------[2 - Sinaut PDM - *F: TimeTolerance!]---------------------

The second alternative starts the description of sequential errors. These lines are, like all the following ones, prefixed by the channel number. Moreover it indicates the current number of the error, the telegram and the error type. Beside the channel number and time, the following lines contain a type identifier, 'P', 'E', 'N' or 'S' in the line head.

(P)revious

contains the last correctly received data record, e.g. :

3-22:08:49.900-P: 68 09 09 68 6F 41 00 10 00 00
                     10: AA AA 00 14 16

(E)rror

marks the beginning of the error description or the representation of the mutilated received data. The form of the representation depends on the transmission mode ( PCM or PDM or simPCM ). With PCM transmission, the correctly received data bytes are recorded up to the occurring error :

4-16:58:33.010-E: 68 06 06 68 6F 01 00 02 55 71
                     10: 16 68 *F: Blocklength !

 

In PDM transmission, the correctly received pulses are recorded up to the fault :

4-17:01:34.320-E:

1:  28.848 ms gap   L
2:    7.310 ms long  H  -0.45 %
3:    7.389 ms long  L  +1.94 %
4:    7.283 ms long  H  -1.26 %
5:    7.348 ms long  L  +0.68 %
6:    3.312 ms short H  -0.53 %  *F: Blocklength !

The description of a pulse must include the length in milliseconds, the type of the signal ( short or long character, blocking time ), the level ( low or high ) and the character distortion in percent.

Note :

If the occurred error is a so-called 'spike', it can happen that two identical levels are recorded in sequence :

2:   3.343 ms short  L  +0.40 %
3:   0.274 ms ......... L         *F: Spike!

In this case the length of the pulse ( of the spike ) was below the minimum measuring accuracy of the receive module and was therefore 'lost'. If you transmit with simulated PCM, in the following example PCM measurement of pulse width, the indication of the pulse length is followed by the number of bits corresponding to this length, e.g. :

4-17:03:50.040-[PulsWm PCM] 4349.531 ms [5226*0] +36.66 %
4-17:03:50.040-[PulsWm PCM]      3.344 ms [ 4*1]       +1.81 %
4-17:03:50.040-[PulsWm PCM]      0.730 ms [ 1*0]      -12.29 %
4-17:03:56.250-[PulsWm PCM] 6115.697 ms [7348*0] +58.01 %
*F: TimeTolerance !

Normally this first description is followed by a series of further error messages giving a breakdown of the sequential errors. These are prefixed by a single broken header.

(N)ext

marks the line following the error messages and describing the first data record received correctly again, e.g. :

1-14:54:50.430-N: EF 41 00 10 C7 6B 9F F6 A0 2B

(S)ync Error

marks synchronisation errors. They are not tied to the order described above, but can occur arbitrarily.

 

6.1.5 Tape recording

For the time measurement, you can also record unknown telegrams ( of any system ) in a so-called tape file and play it back later. Just how tape recording functions is described in detail below ( menu item <SendMessage> commands 'REC' and 'play' ). The directory in which the tape file is to be created can be defined in the program LIAN ( menu item <Protocol | TimeMeasurement | PulseWidth | PulseDurationModulation or PulseCodeModulation | TapeDirectory ).

6.3 Assignment of keys

 

6.3.1 Function keys

If you press the [Alt]-key for about a second, an information line appears at the lower edge of the screen with some of the hotkeys described below. The abbreviations behind the key codes correspond to the function names in the information line, provided they are in it.

[ F1]

Help on the current menu item
( This function should not be called during transmission because of the additional load it burdens the computer. )

[Alt]-[F2] COM Change to the next channel.
[Alt]-[F3] ARC

Activate / deactivate archive recording of the current channel

[Alt]-[F4] PRO

Activate / deactivate protocol recording of the current channel. Entry only in case of error.

The received data are  n o t  written down into the circulation-buffer file as long as the backscroll-window is opened. The user can take any time he needs while viewing the telegrams.

[F10] BckSCL

Activate / deactivate BackScrollWindow. Allows a scrolling up and down in the received data. The received data are still written down into the circulation buffer file despite opened backscroll-window. It can occur during scrolling that with high receiving density old telegrams are overwritten and already the new telegrams are displayed. ( Remedial action: open window with [Alt]-[F10] )

[Alt]-[F11] ZOOM Scales up or down the current channel window (command 'zoom').
[Alt]-[S] Scroll Activate / deactivate sreen scrolling
[Alt]-[X] Exit Quit SIMO ( Menüpunkt <Quit> )

The keys can also be activated without pressing the Alt-key, e.g. the current channel can be changed by means of [Alt]-[F2] as well as by means of [F2].

6.3.2 Entry mask

The following key assignments apply only to the input boxes of the functions <Edit send buffer> and <Edit send sequence> ( see below, menu item  <SendMessage> - commands 'sa' and 'lf' ).

[Arrow right] Cursor rigth
[Arrow left] Cursor left
[Arrow down], [Tab] next field
[Arrow up], [Shift]-[Tab]  previous field
[Enter] quit entry mask
[Esc] Stop editing. Data are not stored.

Please note that the settings are subject to a plausbility check, that means only valid values can be set, otherwise the curser does not move. 

6.4 Menu commands

6.4.1 ComPort

Here you can set the current channel, which is then displayed as a prompt in the command level ( menu item <SendMessage> ).
6.4.2 Terminal

This function is only effective in the terminal mode, i.e. the channel must have been parameterized in LIAN as a terminal interface ( program LIAN - menu item <Protocol | Terminal> ). Via this channel, characters can then be received or transmitted from / to a keyboard. With [Alt] - [F6] the block mode is switched on and off during the terminal mode. If you switch on the block mode, the program buffers all arriving characters until a carriage return (0Ch) or a line feed (0Ah) is received and displays them en bloc afterwards. An entry into the recording files can only be carried out in the block mode. The block mode is used for archiving FWK 16/III-monitor trace records.

By means of [Alt]-[F12] the terminal mode is ended.

6.4.3 Format

Here you can set the display format for each single channel. To which channel the format settings are to be executed must be determined beforehand by means of <Comport>.  

The menu item <Formatis linked to the menu item of the same name in the application TRAP, i.e. the settings are always valid for both programs.

The following format options are available:

StatusHeader A status line with time of receipt is put in front of each telegram.
Hexadecimal Telegram display additionally hexadecimal.
Decimal Telegram display additionally decimal.
ASCII Telegram display additionally as ASCII characters.

 

Binary Telegram display additionally binary format.
LSB
MSB
binary display of received data ( LSB first )
binary
display of received data ( MSB first )

 

Error Display of occurred errors in the following format:

HEX
DEZ
LSB
MSB

ASCII

Display of errors hexadecimal 
Display of errors decimal 
Display of errors binary  ( LSB first )
Display of errors binary  ( MSB first )
Display of errors as ASCII characters

 

Plaintext    

Display of the received data in protocol-specific format. You can distinguish between format 1-3. Only for protocols with long messages (e.g.IEC protocols.

Format 1

Display of the complete message (Header + Information ).

Format 2

Display of header only.

Format 3

Display of information only.

The various options are switched on or off by means of the Enter key.

6.4.4 Notebook

The notebook is a small editor with which you can make notes of the current session. The file size is fixed for 200 lines and 76 columns. Lines cannot be added or removed. With [F10] you exit the editor and store your input on the hard disk in an ASCII file with the extension ‘.pin’. The notebook can be called in all program parts ( in SIMO in the main menu, elsewhere under menu item <Options | Notebook> ).

 

6.4.5 SendMessage

This function opens the SIMO command level. A prompt appears, indicating the current channel. The current channel can be changed if you enter another channel number and confirm it with the Enter key.

6.4.5.1 Editing

 

LF

edit send sequence

With a send sequence you can transmit in succession up to 500 send buffers or the telegrams contained in them ( see also command 'SA' edit send buffer ).

The entry field has the following format :

[line] : [channel] [buffer]

[Channel] indicates through which channel the telegram is to be transmitted. The field [buffer] expects the number of the send buffer ( corresponding to the list displayed by the command 'VIEW') which contains the required telegram. In the send sequence you can also embe instructions that control the run of the sequence. In this case the field [Channel] takes the command code and the field [buffer] the parameter might be needed.

[command code] [Parameter]  
C nnnn counter load
Loads the internal loop counter with the value 'nnnn'.
L 00zz loop, jump to line 'zz'
Increments the internal loop counter and jumps to line 'zz'.
D nnnn delay
Delay program run ( nnnn = 1 corresponds to 100 ms ).
G 00zz jump to line 'zz'
S 00zz

call subroutine at line zz
Instruction to jump to a subroutine which begins in line 'zz'. Subroutines cannot be nested.

R   return
Jumps back to main routine.
E   end prog
Ends the send sequence.

The send sequence is stored and is available again if you call up 'LF' with the next call

Example:

00: c   0002
01: 1   0003
02: d   0005
03: l    0001
04: e   0000
05:

run through loop twice
send message buffer 3 on channel 1
wait 500 msec
jump to line 1
end

The message buffer 3 will be send two times on channel 1  with a gap of 500 msec.  

 

To the simplification of editing more auxiliary functions are implemented over function keys.

[Insert]

insert line
Inserts a new line at the cursor-position and shifts the following lines to the back. The last line of the list (line 99) gets lost with it. The cursor must be set on column "channel".

[Delete]

delete line
Deletes a line at the cursor-position and shifts the following lines to the front. At the end of the list a blank line results. The  cursor must be set on column "channel".

Comment
Because only one internal counter loop exists complex loops are not possible. Loop sequences can be programmed however. To avoid an endless loop you must jump with ‘loop‘ to a command line following the ‘counter load‘.

SA Edit send buffer

To each protocol 500 send buffers are allocated. Each buffer can assume one telegram. The desired send buffer is selected over the number [n] following the command. Is no number given, the sendbuffer put in momentarily is edited.

After calling up the command the telegram mask with which the buffer is to be occupied or edited can be selected via a menu. The data format of the mask depends on the telegram type of which the parameters have been  defined for the current channel <Comport> in the program LIAN.

For technical reasons, not all telegram types can be edited in SIMO. Therefore changes should preferably be carried out with the program TDEP

Syntax:     sa
                sa
[n]               n = Telegram buffer number  0 - 499

sah Edit send buffer hexadecimal

Enters the hex-value [h] in the place of the byte [i] in a record. If the command is called without a parameter, the length and contents of a complete record can be edited.  The command  'sah [i]'  without the parameter [h].
[i] corresponds to the message length that is pre-determined with it.

Syntax:     sah
                sah
[i]                        [i] = message length
                sah
[i] [h]

Range of [i] is 0 up to n. (it starts at byte 0).
sad Edit send buffer decimal

Enters the decimal value [d] in the place of the byte [i] in a record. If the command is called without a parameter, the length and contents of a complete record can be edited.  The command  'sad [i]'  without the parameter [d].  [i]corresponds to the message length [i] that is pre-determined with it 

Syntax:     sad
                sad [i]                        [i] =
message length
                sad [i]  [h]

Range of [i] is 0 up to n. (it starts at byte 0).
sab Edit send buffer binary

Enters the binary value [b] in the place of the byte [i] in a record. If the command is called without a parameter, the length and contents of a complete record can be edited.  The command  'sab [i]'  without the parameter [b] corresponds to the message length [i] that is pre-determined with it

Syntax:     sab
                sab
[i]                        [i] =message length
                sab
[i] [b]

Range of [i] is 0 up to n. (it starts at byte 0).
saa Edit send buffer ASCII

Enters the ASCII char [a] in the place of the byte [i] in a record. If the command is called without a parameter, the length and contents of a complete record can be edited.  The command  'saa [i]'  without the parameter [a] corresponds to the message length [i] that is pre-determined with it.

Syntax:     saa
                sab
[i]                        [i] = message length
                saa
[i] [a]

Range of [i] is 0 up to n. (it starts at byte 0).
sas Edit send buffer (Bitstring)

Enters the bit value [b] in the place of the bit-number [i] in a record. If the command is called without a parameter, the length and contents of a complete record can be edited binary.  The command  'sas [i]'  without the parameter [s] corresponds to the message length [i] that is pre-determined with it

Syntax:     sas
                sas
[i]                        [i] = message length
                sas
[i] [b]

Range of [i] is 0 up to n. (it starts at byte 0).
sq Display a send buffer

To each protocol, 500 send buffers are allocated. Each of these can accomodate one  telegram. The required send buffer is selected via the number [n] following the command. Is no number given, the sendbuffer put in momentarily is displayed hexadecimal, binary or in ASCII in the command window. 

Syntax:     sq
                sq
[n]               n = Telegram buffer number 0 - 499

sw Select a send buffer

To each protocol 500 send buffers are allocated; each of these can accommodate one telegram. The required send buffer is selected via the number [n] following the command; if no number is given, the command 'view' is executed.

Syntax:     sw
                sw
[n]                n = Telegram buffer number 0 - 499

view Display a list of all telegram buffers.

Puts out a list of all telegram buffers with the corresponding commentaries. With the arrow keys you can select a buffer. With the Enter key this buffer is chosen as default-buffer for further treatment.

The following Hot-keys for transmitting are available in the view window :

[s] transmits the selected buffer once

[c] transmits the selected buffer cyclically

 

6.4.5.2 Send

 

FE

set blocking time

For repeated or cyclic transmission, a blocking time [t] ( 0 - 9999 ) can be set between each telegram in which [t] = 1 corresponds to a blocking time of 100 msec.

Please note that [t] only defines the lower limit of the blocking time; therefore,  according to the utilization of the system, it can take longer until the next telegram is sent off

Syntax:     fe [t]

IR

change signal level

This command inverts the present normal signal level on the current channel in order to adjust the normal signal level of the PC and the transmission lines if necessary. The current level is visible at the CDE adapter through the red TxD diode ( = -12 Volt ) or the green TxD diode ( = +12 Volt ).

KILL delete a transmission job

By giving the identification number [id], a particular job in the transmission list ( see also below, command 'ps' display transmission list ) can be deleted. Otherwise the complete transmission list of the current channel is deleted.

Syntax:     kill
                kill
[id]

PS display a transmission list

Displays an overview on the current transmission jobs of the current channel. The display includes the identification number [id] and the commentary for the associated send buffer. Detailed information to a particular transmission job can be requested by giving the [id].

Syntax:     ps
                ps
[id]

SF

activate a transmission sequence

Activates the transmission sequence created by 'LF'. The execution of the sequence can only be ended by entering 'SF' again. If 'SF' is called up without parameters, the execution is started with line 0. Alternatively, a line number can be given for the entry point and another for the exit point ( which is then the same as command 'e' ).

Syntax :    sf
                sf
[start line]
                sf
[start line] [end line]

SM transmission repeated

The buffer selected by 'sw' is sent [n] times.

Syntax:    sm [x]                sends [x] the buffer selected by 'sw'
               sm [x]:n             sends [x] the buffer [n]
               sm [x]:n;m         sends [x] the buffers [n], [m]
               sm [x]:n-m,o,..   sends [x] the buffers [n] to [m] and [o]

The buffer list n-m,o, is transmitted in this order one after the other. Before this list is sent again for the set blocking time, set over fe is waited

One call can contain at most 28 to  transmitting messages 

The parameter [x] or. [x :] with buffer list must be set necessarily.

SS transmission once

Transmits the send buffer selected by the command 'sw' or the parameter 'n'.

Syntax:     ss                  sends the buffer selected by ‘sw‘
                ss n               sends the buffer [n]
                ss n, m..        sends the buffers [n], [m]...
                ss n-m,o,...    sends the buffers [n] bis [m] und [o],

The buffer list n-m,o is transmitted in this order once.

One call can contain at most 28 to transmitting messages

SYNC Generates a cyclic square-wave signal

Generates a cyclic square-wave signal with the frequency [f] on the current channel. The signal is interrupted while a telegram is being transmitted. Signal generation and transmission are possible on one channel only, but the receipt on all four channels.

The CDE adapter must be set for PDM. Calling 'sync' without a parameter ends the signal

Syntax:     sync [f]
                sync

SZ transmission cyclic

Transmits cyclically messages until the process is interrupted by means of the command 'kill' (see above).

Syntax:     sz                  sends the buffer selected by ‘sw‘
                sz n               sends the buffer [n]
                sz n,m           sends the buffers [n], [m],
                sz n-m,o,..     sends the buffers [n] to [m] and [o],.

The buffer list n-m,o is transmitted cyclically in this order one after the other. Before this list is sent again for the blocking time, set over fe is waited.

One call can contain at most 28 to transmitting messages

 

6.4.5.3 General commands

 

ACT actionfilter on / off

If an  actionfilter is set for the current channel ( setting takes place in the program FIPP ) it can be deactivated / activated temporarily with this command. This command correspondents to the input "action enable" in the entry field in the programm FIPP.

Syntax:     act         assume again default-setting "action enable"
                act [n]    deactivate aktionfilter 
                act
[y]    activate aktionsfilter 

The current setting is displayed in the Status window. Changes  of the  previous default-setting in the  filterfile are not saved and get lost after finishing the program SIMO.

ARC write comments to archive

As the eight characters of the DOS-file name are normally insufficient for describing the contents of the archive, you can add a comment to each archive. The command 'arc' opens a window in which you describe the contents of the archive more precisely. This comment is displayed in TRAP together with the archive information

CAL

ascertain correction data

As the UART of the PC cannot process PDM telegrams, this task must be taken on by the software. Consequently, the magnitude of the baud rate at which a trouble-free reception is still possible will depend on the performance of the PC. 'cal' activates a test routine which snaps internal correction data and the above-mentioned baud rate. This does not, however, represent a firm limit but only an approximate one. The test works with any PDM telegram. The transmit and receive cables of a channel must be connected with each other. After a few seconds the result of the measurement is displayed in the window 'SysInfo'. The test must be carried out once only, the result is saved automatically

CDE adapter - switch setting : PDM
CHN channel enable / disable

With this command, recording can be limited on particular channels in the programm SIMO. A channel can be enabled / disabled temporarily. This input correspondents to the input "channel enable" in the entry field in the programm FIPP.

Syntax:   chn        assume again default-setting "action enable"
              chn [n]    disable channel
              chn
[y]    enable channel for receive and transmit records
              chn
[r]     enable channel for receive records
              chn
[t]     enable channel for transmit records

The current setting is displayed in the Status window. Changes  of the  previous default-setting in the filterfile are not saved and get lost after finishing the program SIMO.

CMT add a commentary to the channel

With this command the user can deposit a personal commentary per channel, which is as well displayed in the status window as also saved in the configuration file.  This commentary is not lost after finishing the program SIMO.

Syntax:      cmt     

The window "channel identifier" is opened for the commentary input.

The commentary text can contain at most 22 signs.

EXIT
quit

quit program SIMO 
FLT Filter enable / disable

If a filter is set for the current channel ( setting takes place in the program FIPP ) it can be deactivated/activated temporarily with this command. This input  correspondents to the input "filter enable" in the entry field in the program FIPP.

Syntax:     flt         assume again default-setting "action enable"
                flt [n]    deactivate filter 
                flt
[y]    activate filter 

The current setting is displayed in the Status window. Changes  of the  previous default-setting in the  filterfile are not saved and get lost after finishing the program SIMO.

XINFO display configuration

This command displays not only some of the parameters set in LIAN but also the UART type used by your PC on the current channel:

8250/16450 standard channel processor in the PC
16550 (FIFO)

improved version with integrated temporary buffer, especially suitable for high baud rates (PCM).

Program SIMO recognizes and supports both types

ZOOM

scales up the channel window of the present channel. By adding a channel number [n] the output window of any channel can be zoomed. If you call up 'zoom' once more, all four channels are displayed again.(see function key  [F11].


Syntax:     zoom
                zoom [n

 

6.4.5.4 Special commands ( not available for all telegrams ) :

 

BS bit shifter

To each protocol 500 send buffers are allocated; each of these can accommodate one telegram. The required send buffer is selected by means of the number [n] following the command; if no number is given, the current send buffer is processed.

A window is opened, in which you can shift a bit in the information part of the  current telegram by the arrow keys ( left/rigth ). The interval (1-9)  is determined by the shiftsize. When exceeding the information range the address block is automatically increased or reduced.

The address can be changed with the arrow keys  (up/down ). 

For some protocols ( e.g. Siemens FW537 ) the keys <E> and <A> are used for the bit control "ON" or "OFF".

With <S> the telegram  is transmitted and with <ESC> you can leave the bit shifter again.

This command is not available for all telegrams; please read the respective protocol  description

Syntax:     bs
                bs
[n]

n = Telegram buffer number  0 - 499

RTI Simulation of master station on / off

Activates-/deactivates the simulation of a master station  (see below: command  'rtu').

RTU Simulation of substation on  / off

Activates/deactivates the simulation of a substation. More detailed information on the functioning of this command in connection with the single telegram types (simulation is not possible with all protocols ! ) can be found in Appendix A of the manual or in the LIAN on-line help on the respective protocols under the menu item <Protocol>.

In the simulation mode the commands “sm” and “sz” work differently than in normal  mode: Whereas normally a transmission job cannot be manipulated anymore after being started, now each change of the corresponding send buffer immediately has an effect on the respective job.

PLAY The telegram recorded by 'rec' under [NAME] is played back.

Syntax:     play [name]

REC With this command you can also record unknown telegrams of any system under [name] and play them back by means of the command 'play'.

Syntax:     rec [name]

[name] is selected freely, but it must not be longer than 8 characters and must not contain a full stop. The recording is ended with 'stop'.

Please note the following in connection with this command:

Parameterization in the program LIAN

Measurement of pulse width PCM or PDM must be set with the desired baud rate,  tolerance and ratio of modulation (PDM).

The directory in which the tape file is to be created is set under menu item

<TimeMeasurement | PulseWidth | PulseDurationModulation | Tape-directory>

or 

<TimeMeasurement | PulseWidth | PulsCodeModulation | Tape-directory>

The directory must already exist.

Like for all pulse width measurements, the CDE adapter must be set for PDM

Note:

  • The application of this function is limited to a maximum of 1200 baud

  • Tape files cannot be edited or viewed at the present time.
