Dear Expert.
I want to use Modbus TCP Library from PLCnext store for my project.
I my project, My AXC 2152 work ass Modbus TCP client to read/write data to Modbus TCP meters.
I don’t know how maximum Modbus TCP meter my AXC 2152 can connect via Modbus TCP Library?
Many Thank
Hello, it will depend on the way you want to organize polling process.
For simultaneous connection you can reach up to 63 devices via instanced tcp client fb’s. This number is limited by TCP/TLS port handling opportunity of plc.
But if you will organize sequential read/write access to meters, one by one, the number of devices is almost unlimited. You just change configuration of single tcp-client fb, do the staff and disconnect.
