hi, i have the same plc function, and the program is running good, i have a plc r series "r04" and im using rj71c24-r4 with rs485 and serial modul with predefined protocol support function in ch2, im using half duplex and my slave modbus rtu has id:1, the problem is when i want to add another device with id:2 and i created another protocol, but only id:1 works the id:2 is no readed, actually my program is based in this example. someone who can guide me how to correctly register the second device
thanks
