NT2S with C2000H

[IO_Rack 181]

I am trying to connect an NT2S-SF121B-EV2 to a C2000H through a C500-LK203. They do communicate. I can change screens but I cannot set a bit in the PLC using the function buttons. I get the error on the NT2S reading: Cannot write this Register... I have tried various (if not all) memory areas. I have tried using a different NT2S with the same results. I have used the same connection with an NT21 touchscreen and was able to set bits in the PLC. I have also used the NT2S with a CPM2A and a C200HG both with success. It appears as though the NT2S is just not capable with the C2000H. Omron support tells me is should be possible, they are checking on it now. Anybody know what is going on? Thank you, IO Rack
