2.1 LIAN 98  Protocol Router


 

 

 


IEC101/ IEC104 ROUTER

 

Protocol 60870-5-104 ( TCP / IP ) over LAN is increasingly used for the connection to control centers. Companies already running IEC 60870-5-101 substations can convert the serial protocol IEC 101 into the network protocol IEC 60870-5-104 with LIAN 98. In this way it is possible to maintain the complete telecontrol equipment.

LIAN 98 offers a PC-based cost-effective and fast software solution for the transmission between control center and substation. The great advantage of this software solution is the ability of LIAN 98 to supervise, analyse and archive simultaneously to the router function the data traffic on errors. The integrated simulator ( see Protocol Simulator ) and the integrated analysis function ( see Protocol Analyzer ) makes it possible.

The integration of systems into LIAN 98 is very easy due to low efforts in parameterization. Therefore the router can be adjusted fast and without problems. The configuration is limited only to a few parameters such as e.g. the correlation from ASDU addresses to the channel number. Because the user data transmitted transparently, no data point descriptions are required.

 

 

When during commissioning not all system components ( e.g. the IEC104 client or a IEC101 substation ) are available it is of course possible to simulate temporarily the missing components for the integration test with LIAN 98.

In the following example the IEC104 client is simulated with channel 3 and the IEC101 substation with channel 2 while channel 1 and 4 assume the function of the router.

Parameterization

 

 

 

IEC 60870-5-104 Server/ Router

 

 

aktivate router

yes / no

The router function is additionally to the internal "IEC104 Server-simulation" enabled when this parameter is activated. The software is therefore in the router mode after switching on the server simulation.
see also IEC 60870-5-104 : RTU ( Server/ Slave ) Simulation

Telegram format

With this parameter the telegram format of the connected substation is selected ( at the moment only IEC 60870-5-101 ).

Insert routing addresses
Number of adresses
delete
insert

All connected substations which should be taken into account from the IEC104 router are to be entered into the station list.

In order to insert the addresses please proceed as follows :

activate "insert routing addresses" ( button "insert" is displayed ).
Insert in the fields "Address of ASDU" / "Channel number" the station to be entered. Take over the address by clicking "insert". When all stations are inserted please deactivate "Insert routing addresses" ( button "insert" disappears ).

In order to delete one or more stations out of this list select it and click "delete".

 

 

 

 

End of initialization

yes / no

When this parameter is activated after the establishment of the connection to a client "End of initialization" will be transmitted automatically from LIAN 98 as server.

For the operation of the router this parameter has to be deactivated because the substation message "End of initialization" has to be sent from the substation.

Use system time

yes / no

When this parameter is activated the system time of the PC is entered as time stamp before sending the telegrams. Otherwise the telegram remains unchanged as it previously has been edited by the user.

For the operation of the router this parameter has to be deactivated because the current time is already entered by the substation

Send ACTCON respond

yes / no

When this parameter is activated LIAN 98 will send during server simulation automatically a "activation confirmation" ( COT 7 ) or "deactivation confirmation" ( COT 9 ) after the receipt of an "activation" ( COT 6 ) or "deactivation" ( COT 8 ) command.

For the operation of the router this parameter has to be deactivated because the confirmation messages ( COT 7 ) or ( COT 9 ) has to be sent from the substation.

Send ACTTERM respond

yes / no

When this parameter is activated LIAN 98 will send during server simulation automatically a "activation termination" ( COT 10 ) delayed by the "ACTTERM delay time".

For the operation of the router this parameter has to be deactivated because the "activation termination" ( COT 10 ) e.g. at the end of a general interrogation or after the command execution has to be sent from the substation.

Send ACTCON respond
on test command

yes / no

When this parameter is activated LIAN 98 will send during server simulation automatically a "activation confirmation" ( ID 107, COT 7 ) after the receipt of a "Test command activation" ( ID 107, COT 6 ).

For the operation of the router this parameter is activated for the test of the network connection between client and server.

 

 

 

IEC 60870-5-101 Master/ Router

 

 

Activate router

yes / no

The router function is additionally to the LIAN 98 internal "IEC101 Server-simulation" enabled when this parameter is activated. The software is therefore in the router mode after switching on of the master simulation.
see also IEC 60870-5-101 : RTI ( Master ) Simulation

Telegram format

With this parameter the telegram format of the connected client/ master is selected. ( at the moment only IEC 60870-5-104 ).

Route ACTCON respond

yes / no

A substation sends automatically a "activation confirmation" ( COT 7 ) or "deactivation confirmation" ( COT 9 ) after the receipt of an "activation" ( COT 6 ) or "deactivation" ( COT 8 ).
LIAN 98 will forward a confirmation message to the client computer of the control center after the receipt when this parameter is activated.

Route ACTTERM respond

yes / no

A substation sends e.g. at the end of a general interrogation or after the command execution automatically a "activation termination" ( COT 10 ).
LIAN 98 will forward a termination message to the computer of the control center after the receipt when this parameter is activated.

 

 

 

 

Activate time synchronization

yes / no

When this parameter is activated LIAN 98 will send at first a time synchronization command after the initialization of the communication and repeat it cyclic if necessary ( time SYNC cycle ).

For the router operation this parameter can be activated or deactivated. If it is deactivated a time synchronizations command from the client computer of the control center is expected and forwarded to the substation.

Use system time

yes / no

When this parameter is activated the system time of the PC is entered as time stamp before sending the telegrams. Otherwise the telegram remains unchanged as it previously has been edited by the user.

For the router operation this parameter has to be deactivated because the current time is already entered from the client computer of the control center.

Activate general interrogation

yes / no

When this parameter is activated LIAN 98 will send a general interrogation command after the initialization of the communication and repeat it cyclic ( GA cycle time ).

For the router operation this parameter can be activated or deactivated. If it is deactivated the general interrogation command is expected from the client computer of the control center and forwarded to the substation.

Send execute command

yes / no

When this parameter is activated LIAN 98 will send automatically a "activation, execute command" ( COT 6, execute command ) during the master simulation after the receipt of a "activation confirmation, select command" ( COT 7, select command )

For the router operation this parameter has to be deactivated because the command execution is managed from the client computer of the control center.
