Values RS485

[Olivera 0]

Hello: I have a Power Meter (PM500 Merlin Guerin) connect to a PLC (controlLogix Allan Bradley) via RS485 with the help of a modbus module (MVI56-MCM). How can I see the values that the power meter transmit to the modbus module in the RSLogix? Thanks.

Olivera. I have many Merlin Gerin power meters used in exactly this way but your part number does not make sense to me. The meters I am familiar with are the PM700 series but only the PM710 has the Modbus port. There is quite a lot of code involved in setting up the Prosoft card and then sorting and scaling the data from the meter but I might be able to help if you can give me the exact MG part number.
