For the library version “MODBUS TCP v4”, Does it have the limitation of the number of server connection ?
Hello, Here was a recent discussion about the number of Modbus TCP servers that can be connected to, from a single AXC F 2152: https://www.plcnext-community.net/en/discussions-2-offcanvas/profinet-and-modbus-tcp.html The short answer is: There is no artificial limitation on the number of servers that you can connect to using the Modbus TCP client in that FB library. Hope this helps. ~ Martin.
