Can Modbus modules on Ignition (Modbus TCP or ModbusRtuoverTCP) connect to MOXA devices (5110, 5250A, 5150A) and read their data over Modbus TCP? The Moxa device is connected to a counter which communicate with MOXA over Modbus serial.
You can use the Modbus RTU over TCP driver but it’s really a worst case scenario. You’ll have to make sure absolutely nothing else but Ignition is connected to these serial-to-ethernet converters. RTU over TCP is not a reliable protocol because there’s no framing or sequencing of requests. It’s possible for things to get out of sync and start seeing mismatched requests/responses.
Ideally you would use one of the Moxa MGate devices that actually convert Modbus RTU to Modbus TCP.
A counter is connected to this Moxa and on its datasheet the addresses are like this:
How should I write the Modbus addresses? is it IRUI_6421636?
Yeah, that seems right (IR or HR, can’t tell from the screenshot). You might have to try +1 or toggle the one-based address setting.
