The default port for Modbus TCP in C-more is 502. In your P1AM-100 for example below line 7 for EthernetServer. We also have an example program available:
https://github.com/AutomationDirect/P1AM-Examples/tree/master/P1AM-100_ModbusTCP_Server_HMI
IPAddress ip(192, 168,1, 2); //IP Address of the P1AM-ETH module. boolean MB_C[16]; //Modbus Coil Bits boolean MB_I[16]; //Modbus Input Bits int MB_HR[16]; //Modbus Holding Registers int MB_IR[16]; //Modbus Input Registers EthernetServer server(502); EthernetClient clients[8]; ModbusTCPServer modbusTCPServer; int client_cnt;
