Hi,
I'm having some issues getting my PLC to talk with a meter and genset controller over Modbus.
The PLC is a ControlLogix 5572 with 2 Prosoft cards - MVI56E MCM and MNET.
The meter is an Eaton PXM 2000.
The genset controller is an Onsite Energy MGC-2010.
I was kind of thrown to the wolves with this project as I don't have much Modbus experience other than the basics taught in school.
The meter and genset controller both have ethernet ports on them and are to be connected to a switch, and connected to the PLC through the EN2T card. This leads me to believe that the MNET card is to be configured as a client (master) to poll values from the devices and the MCM card is to act as a slave to feed values to SCADA.
I'm just having difficulties getting the devices to talk to the PLC. I'm only trying to talk to the meter at the moment, as it has less values I need to pull and I have more info about it. I've followed the instructions on Prosoft's website for setting up the card in the Configuration Builder, it all seems setup right to me. But I'm not reading any values from the meter at all right now, and the APP LED on the card flashes red occasionally which I believe signals communication errors.
Any ideas on which direction I should start in?
Thanks
