our project used the mqx4.1 with tcp/ip stack, and the function modbus tcp is available. but now we encountered a question is that when the maximum multilink connection number is 4, and when the modbus tcp clients become 5 to connect to our Module(modbus server with mqx4.1 of tcp/ip stack) at the same time. the connections sometime is not good and stable.
My question is that is there any constraint about the tcp connection numbers?
Thanks & BR,
