With the channel button ( channel 1 ...12 ) on the bottom following settings are possible :

Each character has one start bit ( binary = 0 ), 8 information bits and normally one even parity bit and one stop bit ( binary = 1 ).

For each channel any COM port ( COM 1 till COM 24 ) can be selected.

An individual modem can be installed and connected for each channel. LIAN 98 is able to process up to twelve modems in the range of COM1 till COM24 simultaneously. Select here the modem assigned to the selected channel. Normally this assignment will be recognized by LIAN 98 and the corresponding modem will be set.

The settings of the modem must be executed via the windows control panel "telephone and modem options". With this button you can check the modem settings and see if they correspond to the LIAN 98 configuration.

0 ... 1000 msec
This parameter ist only used for the connection type "half duplex" and is determined by the initial transient behaviour of the used transmission equipment.
The RTS Leading defines the delay time from activating RTS signal to transmitting the first character and is used for modems whithout the hardware handshake signals "RTS and CTS". In this case the "RTS signal" must be led back over the "CTS line" to the PC with the help of a brazing bridge in the monitor cable. Dependent of the used modem it may be necessary to connect additionally the DTR-pin with the DSR-pin.
This function is deactivated if the "Leading and the Trailing" is set to NULL and therefore the control signals are analyzed diectly from the modem.

0 ... 1000 msec
This parameter ist only used for the connection type "half duplex" and is determined by the final transient behaviour of the used transmission equipment.
The RTS Trailing defines the delay time from the last character transmitted up to the RTS signal is deactivated.
This function is deactivated, if the "Leading and the Trailing" is set to NULL.

All telegrams to be sent are provided with the station number of the SIM list during master simulation. .Exception for unbalanced mode :

. If the station number 255 ( one octet address ) of a "BROADCAST command" is inserted in a telegram of the TDB buffer, the telegram will be transmitted unchanged with the address already inserted.
 
. If a station number of the scan list is inserted in the telegram it will be transmitted unchanged with the address already inserted.

1 - 30 000 msec

A fixed time out interval is provided to be used for repeated transmissions. The time out interval and maximum number of retries are configurable and appropriate values will depend on the transmission system.

This parameter determines the time in milliseconds that the program LIAN 98 as primary station at most has to wait for an acknowledge before the last transmission is repeated.

0 - 255

Via this parameter it is defined how many times the transmission is to be repeated when the acknowledge is missing.

yes / no

After the initialization of the communication LIAN 98 will transmit first of all a time synchronization command and will repeat it cyclic ( Clock SYNC cycle time ), if this parameter is activated.

1 - 1440 minutes

Dependent on this time LIAN 98 as master station will transmit the time synchronization command continually.

TDB buffer number where the organizational telegram ( ORG 256 ) is stored.

yes / no

The system time of the PC will be taken over into the time synchronization command ( ORG 256 ) before the telegram will be transmitted, if this parameter is activated. Alternatively the telegram remains unchanged as before edited by the user.

yes / no

After the initialization of the communication LIAN 98 will transmit a general interrogation command and will repeat it cyclic ( GI cycle time ), when necessary if this parameter is activated.

1 - 1440 minutes

Dependent on this time LIAN 98 as master station will transmit the general interrogation command continually.

TDB buffer number where the organizational telegram ( ORG 0 ) is stored.

Unbalanced : ( party line )
All stations to be processed at this line have to be inserted into the scan list. LIAN 98 establishes the connection to this stations and interrogates continuously the user data of this stations.

In order to insert the addresses please proceed as follows :

Activate "Insert scan addresses" ( button "insert" will be displayed ).
Insert in the fields "Link address" / "Address of ASDU" the station to be entered in the scan list.
Take over the addresses into the scan list by clicking "insert".
When all stations are inserted, please deactivate "insert scan addresses" ( button "insert" disappears ).

In order to delete a station out of this list select it and click "delete".

Unbalanced : yes / no

When the communication establishment is finished, LIAN 98 starts automatically the request of the user data ( polling ). If it is not wanted the request can be deactivated here.

Unbalanced :
Number of the TDB buffers where the polling telegram is stored.

Unbalanced :  0 - 30 000 msec

This parameter determines the time that the program LIAN 98 delays the next polling telegram. 

Unbalanced :
Number of the TDB buffer where the acknowledge of the master ( A2H ) is stored. 

All telegrams to be sent will be provided with station number out of the SIM list during slave simulation.

All telegrams to be sent will be provided with the source TLN number out of the SIM list during slave simulation.

All telegrams to be sent will be provided with the target TLN number out of the SIM list during slave simulation.

Balanced : 1 - 30 000 msec

A fixed time out interval is provided to be used for repeated transmissions. This time out interval and the maximum number of retries are configurable and appropriate values will depend on the transmission system.

This parameter determines the time in milliseconds that the program LIAN 98 as substation at most has to wait for an acknowledge before the last transmission is repeated.

Balanced : 0 - 255

Via this parameter it is defined how many times the last transmission is to be repeated when the acknowledge ( only balanced ) is missing.

yes / no

The current system time of the PC is given back in the "activation confirmation" of the time synchronization command, if this parameter is activated. Otherwise the received time will be only mirrored.

yes / no

The system time of the PC will be adjusted to the received time values of the time synchronization command ( ORG 256 ), if this parameter is activated.

0 - 9 999 msec ( correction of transmission time )

A correction value can be entered for the setting of the PC system time with a time synchronization command. It will be added onto the received value in the synchronization command.

TDB buffer number where the organizational telegram ( ORG 256 ) is stored.

yes / no

The system time of the PC will be inserted in the time stamp of the telegram before transmission. Otherwise the telegram remains unchanged as before edited by the user.

Unbalanced :
Number of the TDB buffer where the acknowledge of the master ( E5H ) is stored.

The general interrogation is used in order to update the controlled station after the initialization or when the controlling station detects a loss of information. 
The general interrogation function of the controlling station requests the controlled station to transmit the actual values of all processing variables. The interrogation procedure is finished when the controlling station receives the message "end of interrogation"

Date and time of controlled stations are initially synchronized by the controlling station after initialization and afterwards re-synchronized periodically.

yes / no

With this option already set monitoring filters for one channel can be deactivated temporarily without deleting them.

Here monitoring can be filtered for telegram specific values in which several OR-linked filter masks can be defined for the channel.

yes / no

With this option already set action filters for one channel can be deactivated temporarily without deleting them.

The action filter is described over telegram specific features corresponding to a filter setting. Additionally each action filter requires an allocation to a send buffer or alternatively to a send sequence.

In correspondence with the action filter the message buffer "from" or the message buffers "from/ till" are to be sent.

In correspondence with the action filter the send sequence is to be started at line number "from" or to be started at line number "from" and to be ended at line number "till".

yes / no

Within a telegram, there may be no pause between characters. In case of timeout occurs it is assumed that it is the end of the telegram and the telegram check is started. The sensitivity can be parameterized in the configuration ( timeout ).
Normally a time out is no error, but it is stored in the PRO file together with the initial error for a better analysis of the faulty transmission line in connection with a line error.

Error during writing on the COM port. May be it is already occupied by another program.

The length of the telegram is wrong. For telegrams with fixed length the length is not 5.

The repetition of the length or the start characters ( 68H ) in the message header are faulty, or the stop byte ( 16H ) is missing or set wrongly.

The message checksum in the checksum byte is incorrect.

The receive routine initially searches for 68H, 10H, E5H ( or A2H ). Each other character is noted as synchronization error and inserted in the PRO file.
