Micro820 Modbus mapping

Hi all, I am trying to connect Allen Bradley Micro820 to my ignition with Modbus TCP
Do you know how I can Config Modbus mapping
I have 4 digital input and 4 digital output in the device nothing else

would you please help if you can?

You don’t have to use the map…

I don’t suppose the micro820 shows the modbus equivalent in its ladder editor…

youll have to map the plc tags to ingition tags using an opc path

If your are just trying to get the PLC “Tags” into Ignition, I can recommend another easy and efficient way to get that job done.

By using a Maple Systems MQTT Gateway at a cost of $390.00 USD. you can directly communicate with Ignition. If you setup Sparkplug B it works flawlessly!
