Hi Charles,
You need determine the registers on the air compressor(s) that you want to read and write and configure them in the gateway. You will need the memory map for the compressor to do this. Once that is complete, you will need to adjust the I/O size on the PLC so that it matches the gateway. You’ll have to delete the gateway module and create a new one if the I/O sizes change. We can’t do this for you, but we can help if you have questions.
