Dear Experts.
I’m using MODBUS TCP LIBRARY from PLCNext Store.
The required diagram like attached picture.
In configuration, each MODBUS TCP client have max 10 function block to read and control.
In my diagram, The block more then 10.
How should I do?
Thank much.
Hello!
In cases, when I have to read data from several modbus nodes via gateway, I use single modbus tcp fc block and reconfigure it before initiate next poll cycle. In this case you may read all nodes after gateway, but it will take a little bit more time to process connection data.
