Protocol : Siemens - SINAUT ST1


 

The protocol Siemens ST1 is also available in the LIAN 98 Software,
running under the operating system Microsoft® Windows® ( 32 Bit ).

Telegram structure

The following data types are distinguished :

Attention :
Differently from the telegram description station- and message numbers from 0 to 255 are accepted without error message.

Abbreviations:
TZ

  
Telegram counter (0....7
0       = qualifier of initializations
1....7 = 1. to 7. telegram
KC
  
  
  
  
  
  
  

  
  

control code
with polling operation.
 
in reply telegram
      0 = n. telegram
      1 = last telegram
   in polling telegram
      0 = normal telegram
      1 = 1. telegram after initializations

with spontaneous , cyclic operation ( acknowledged )
      0 = n. telegram
      1 = 1. telegram after initializations

FA
  
  
choice of functions
0 = telegram is to be processed by receiving TIM
1 = telegram is to be processed by receiving basic station
TA
  
  
  
telegram type
0 = organization telegram
1 = free
2 = data telegram
3 = interrogation telegram
ZK
  
additional qualifier for telegram type
e. g. meaning of organization telegrams

 

For the different data types there are telegrams with the following information in standard mode :
Monitoring telegrams :

Telegrams with analogue values :

Telegrams with integrated totals :

Control telegrams

Set point telegram 

6 or 32 messages

4 or 8 analogue values

1, 2 or 4 integrated totals

8 commands

1 set point 

In addition to  these standard telegrams user-defined Sinaut ST-telegrams can  be created. You can combine and analyse any data volume whatever ( max. 120 bytes ) and / or mixed data types. 

Depending on the information type Sinaut ST telegrams occupy 1 to 4 bytes maximum. For further details please see your system's manual.

Information types

Since the individual telegram types often can only be distinguished by their address , a list for the type identification must be created or loaded in the program LIAN over menu item settings | Information types or File | Load | INFtyp. This list ( SIMO.TYP ) describes the allocation of the telegram address to the telegram type.

Sinaut ST1 telegram types   control direction :
type 17 = TDB_ST1_BF8 
type 18 = TDB_ST1_SW1 
type 19 = TDB_ST1_SW2 
type 20 = TDB_ST1_BM1 
type 21 = TDB_ST1_BM2 
control telegram 8 commands
set point telegram types 1
set point telegram types 2
bitmap types 1 ( 16 bit binary ) 
bitmap types 2 ( signed integer )
Sinaut 8-FW telegram types monitoring direction:
type 01 = TDB_ST1_ML8
type 02 = TDB_ST1_ML16
type 03 = TDB_ST1_ML32
type 04 = TDB_ST1_MW1 
type 05 = TDB_ST1_MW4 
type 06 = TDB_ST1_MW8 
type 07 = TDB_ST1_ZW1 
type 08 = TDB_ST1_ZW2 
type 09 = TDB_ST1_ZW4
monitoring message 8 bit
monitoring message 16 bit
monitoring message 32 bit

measurand 4x16 bit
measurand 8x16 bit
counter 1x32 bit
counter 2x32 bit
counter 4x32 bit

Transmission errors

*F:BCCode : The telegram check sum is incorrect.
*F:Block length  : The stop byte 16H is missing or set wrongly.
*F:TelFormat : The repetition of the length or the start sign in the telegram header is faulty.
*F:TimeOut :
  
Within a telegram , there may be no pause between characters. The sensitivity of SIMO can be parameterized in LIAN.
*F:SYNC : 
  
  
The receive routine initially searches for 68H , 10H , E5H or A2H. Every other character is given an asterisk "*" in SIMO and a synchronization error is noted against it in the protocol file.
*F:Overflow : Error message by UART.
*F:Parity : Error message by UART.
*F:Start/Stop : Error message by UART..
