I have not had any luck reading any setpoint info from the 3504.
PROSOFT MVI56E MNET MANUAL
The Eurotherm manual has an entire chapter in their Engineeing and Design guide that lists all of the Modbus addresses for setpoints, process values, etc. I am confused about the addressing for reading/writing information from the Eurotherm. Please reply once you have figured out the actual device network.I am using a ControlLogix PLC system with a ProSoft MVI56E-MNET to communicate with a Eurotherm 3504 temperature controller.
PROSOFT MVI56E MNET GENERATOR
You'll also need to know the IP addresses that you'll assign to the MNET card port, and the Generator (or SCADA). With that in mind, you need to configure Client commands in a conceptually similar way to the MCM, but with different software: Prosoft Configuration Builder. Rather than "master/slave " the MNET card uses different terminology because it can have multiple "masters" or "slaves." Internal to the MNET card lives a database which we'll call the "server." Devices connected to the MNET card are "clients." The MNET card can request data from a client (a device such as the generator), or a client can request data from the MNET card (such as a SCADA system / RTU / DCS etc). I suspect that the generator was supplied with ModbusTCP gateway which would explain the MCM and the MNET in one PLC rack. Scenario 2 - PowerXpert Modbus Serial, Generator ModbusTCP: Just a note that the IntAddress parameter refers to the MCM's internal database. Next, you need to configure 1MasterCommand for every command you wish to send to the PowerXpert, and generator. Configure 1 for this network (baud, parity etc). For this to happen, the jumper on the card needs to be set to match the settings of the device (i'm guessing RS-485). In this case, the MCM is the master, and the two devices are slaves. The MCM card will be used to communicate to both devices. Scenario 1 - PowerXpert and Generator via Modbus Serial: The following assumes you have imported both of the Prosoft AOIs. The generator would have been shipped with a TCP gateway if ModbusTCP was requested.
PROSOFT MVI56E MNET SERIAL
The PowerXpert and the generator controller can communicate with either Modbus Serial or TCP depending on what was specified. Ignoring the PLC cards for a moment, you first need to determine whether the devices are using Modbus serial or Modbus TCP. You said that PLC has an EN2T which I suspect is connected to the SCADA system. You're in luck because I am doing this exact thing at another site, except the generator is connected to the DCS rather than the PLC. 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.Īny ideas on which direction I should start in? 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. 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'm just having difficulties getting the devices to talk to the PLC. 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. 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. 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 genset controller is an Onsite Energy MGC-2010. The PLC is a ControlLogix 5572 with 2 Prosoft cards - MVI56E MCM and MNET. I'm having some issues getting my PLC to talk with a meter and genset controller over Modbus.
