RS485 communication between PM556-TP-Eth and MFM
Dear All,
First time, I am going to establish RS485 communication between PM556-TP-Eth and Multifunction Meter (MFM). MFM model is EM6400NG. I want to read data from MFM. But, I am unable to understand how to start . Please assist me providing manuals / sample program so that I can read data from MFM. Please provide documents for physical connection.
Regards,
SS

Hi,
You can use COM_MOD_MAST Block for reading data form Mod bus slave. The Following Steps need to be performed.
Configure the Com port of PM556-TP-ETH port as RS486 Mater and in Codesys using the COM_MOD_MAST block you can read the Data.

Hi. I can guide you for the steps to be followed. with a little understanding o1. f the process (automation builder) you will be able to find solution of your issue:
1. install Automation builder & create a new project.
2. Select the PLC & its terminal base
3. create a modbus TCP server in ethernet interface
4. Have physical connection with the module. Scan the module, it will show default IP of moduel. give new IP address for module & "send configuration" to the device
5. create "New Channel" in communication settings. set IP of controller.
6. Save this section. now you can start the programming section. Define Global variables.
7. From Library manager, select th librarries to be used in project.
8. Create FBD like the shown in attachment for each parameters.
9. Assign Task connection just like AC800M & RUN
Even after this you are not able to do the programming then I have attached 1 program for your reference. :)
But I would like you to try the above steps first.
Thanks
