Access to a Massive Modbus Template Library!

These gateways offer predefined templates to over 400 Modbus devices from over 70 vendors. A simple click of a template file and your gateway is configured to move data from Modbus devices to your Allen-Bradley PLC. No more manually entering tables of Modbus registers, no mapping of those data points to PLC tags. You do not even have to create the controller scope tags in your PLC! A ready to load file will generate the controller scope tags with appropriate naming in your PLC. The only thing you have to do is properly assign the IP and serial network settings. These are available to you at NO extra cost. See the full list of device templates.
