IOL_CALL (FB) ¶ FUNCTION_BLOCK IOL_CALL This Function Block enables access to access IO-Link data or initiate port functions using PN-IO mechanisms. Client applications could use it to parameterize a Device with (IO-Link-) AL_Write or read out data like the SerialNumber with the help of an (IO-Link-) AL_Read. In order to address the required IO-Link data, IOL_CALL uses PROFINET access points (“record index”) and the Master port number in addition to the IO-Link Indices and Subindices as well as the transfer direction. For details see: PI Specification, IO-Link Integration, Part 1, Version 1.0, December 2007, Order No. 2.812 PI Specification, IO-Link Integration - Edition 2, Version 1.0, June 2017, Order No. 2.812 Example PROGRAM PLC_PRG VAR al_read : ProfinetCommon.IOL_CALL ; err : ProfinetCommon.IOL_Error ; productText : STRING ( 64 ); END_VAR //start the execution by setting REQ = TRUE ! al_read.ID := al1100.GetID ( 0 , 1 , 3 ); // ID of IO-Link Device (in Port 2) al_read.CAP := 16#B400 ; // Fix for Ed. 2 devices.

The function block is not ready to perform a new task. ERROR BOOL Flag indicating the abortion of the function with an error STATUS DWORD Completion or bus error code. Busy =0xFFFFFFFF IOL_STATUS DWORD Completion or IOL-M and IOL-D error code. See function TO_IOL_Error RD_LEN INT Actual Length of data that has been read.
