I have an AB7649 XGateway which I want to use to pass data between an Allen Bradley Plc and a Siemens Plc. I have configured the XGateway with four bytes of input data and four bytes of output data.
I have the ControlLogix Plc code working, it is sending data to the XGateway and I can see the data from the XGateway web page.
Then I followed the instructions in the application note SCM-1202-052 on how to add the XGateway into TIA Portal. This seemed to go per the instructions except I noticed one difference. The notes show a picture of the input and output bytes with I and Q addresses apparently assigned to them.
However, when I added the input and output bytes to my project they do not show addresses.
When I go to the watch table to try to see the incoming data, it does not show any non zero values, as what should be coming from the gateway.
Do I need to somehow assign addresses to the input data? Or am I looking at the wrong input addresses? Thanks,
