Hello,
I want to build-up a test bench, by using a Sinumerik 840D keyboard and a S7-300 PLC. The two devices are communicating through Profibus.
The keyboard is recognized as addrsss in Step 7, but the PLC can't comunicate with it. All LEDs on the keyboard are blinking.
I know that in a CNC the keyboards first dialogates with the CNC, which then comunicates with the PLC.
How could I do to communicate with the keyboard directly ? (so, not through the CNC).
It seems that the keyboard needs some confirmation signals, but I don't know how to provide those signals.
Thank you.
