Hi everyone I'm using cpu s7 300 & cp341 as modbus rtu master. But unfortunately the communication doesn't establish and neither of CP341 LEDs blink. I have inserted the dongle and installed essential softwares (CP PtP Param v.5.1.15 and modbus master 3.1sp8) on PCS7. FB8 has status code 16#301. Diagnostic buffer of CPU & CP has no fault. I'm totally confused. I have attached some pictures of my work and would be thankful if you could take a look and help me as soon as you can. Thank you so much...
