Basic settings: Protocol parameters

The behavior of the substation can be adapted to the requirements of the master via the IEC60870-5-104 protocol parameters. Most parameters have preallocated default values that do not have to be changed.

The values of the iK and iW parameters are changed in our example:

IF init THEN 
init := FALSE; 
... 
F_CreateServerHnd( '', '127.0.0.1'(* change this! *), 2404, nMode := LISTEN_MODE_CLOSEALL OR CONNECT_MODE_ENABLEDBG, bEnable, hServer); 
 
server.protPara.iK := 12; 
server.protPara.iW := 8; 
 
ELSE 
server( pInputs := ADR( inputs ), 
cbInputs := SIZEOF( inputs ), 
pOutputs := ADR( outputs ), 
... 
END_IF
