iParServer (FB)¶

FUNCTION_BLOCK iParServer

Handles iPar-Request for a single slot/subslot of a Field Device.
Default implementation which stores iPar data on filesystem can be replaced by own implemenatation of IIParameterData.

iPar-Server Example

PROGRAM PLC_PRG
VAR
   iparServer : iParServer.iParServer;
   paramDB : iParServer.DefaultIParameterDB;
   iParData : iParServer.DefaultIParData;
END_VAR

iParData.stFilename := 'iParTest';      // default implementation stores data on file system
paramDB();                              // file access, do not exec in realtime task !

//call ipar server with module ID of the PROFIsafe module
iparServer(ID := IoDrvProfinetBase.GetID(fmodule), DATA := iParData);
