  1. CALL FUNCTION

    Hi Guys. I'm new to GX Works2 and to PLC programming in general. I'm having some trouble understanding a part of a software from a machine. Throughout the project I find the "CALL","XCALL","ECALL","EFCALL" function. I attached a print screen of one of them. I don't understand exactly how it works. I tried doing a similar small program and simulating it but the ERR light in simulator keeps blinking RED. Can you guys help me because the HELP for this function is not very clear to me. Thanks
