Read/Write variable from PLC

Casius

Hello,
       It's possible to read a numeric variable (integer) from Rapid using a PLC Siemens? And to send from PLC back to Rapid. I have IRC5 controller.
Thank you!

Hi, if it is just an integer, I have found that mapping the integer required (both In and Out) to a group input/output on the robot-side works just fine for me. I do this all the time, albeit it is an Allen-Bradley PLC communicating over Ethernet IP, but it's 6 of one, half-dozen of the other! You should be able to get that to work no problem.

Simple Syntax:

        VAR dnum dnIntegerRequired;

        dnIntegerRequired := GInputDnum(gi_IntegerFromPLCyouWant);

        SetGO SignalGOToPLC, DnumToNum(dnIntegerYouWantToPass);
