ADDR_TO_ID (FB)

FUNCTION_BLOCK ADDR_TO_ID

The function block ADDR_TO_ID converts the physical identification of a slot of a PROFIBUS DP-slave or subslot of a PROFINET IO Device to a handle which can be used with the Communication Function Blocks.

Code-Example: get ID with ADDR_TO_ID

PROGRAM PLC_PRG
VAR
   ID : DWORD := CommFB.Constants.INVALID_ID;
   convertAddr : CommFB.ADDR_TO_ID;
   addr : CommFB.ADDR_TYPE;
   errorCode : UDINT;
END_VAR

addr.SYSTEM := CommFB.IO_SYSTEM_TYPE.PROFINET_IO;
addr.PN.MASTER := PN_Controller.MasterID;
addr.PN.D.STATIONNAME := 'wago1';
//addr.PN.D.INSTANCE := ?;      Instance Nr - not relevant for ADDR_TO_ID()
//addr.PN.D.DEVICE := ?;        Device-ID   - not relevant for ADDR_TO_ID()
//addr.PN.D.VENDOR := ?;        Vendor-ID   - not relevant for ADDR_TO_ID()
addr.PN.API := 0;
addr.PN.SLOT := 2;
addr.PN.SUBSLOT := 1;

convertAddr(EN := TRUE, ADDR := addr);
IF(convertAddr.ENO) THEN
   ID := convertAddr.ID;       // --> use this ID in RDREC, WRREC etc.
ELSE
   errorCode := convertAddr.STATUS;        //failed !
END_IF
