Module IO

Hallo everyone, I need your advice. I already used module IO "Wellpro

I used 24 Vdc to power up. When I connected with PLC using serial communication. The led is red (error).

I also tried switch the cable (Tx, Rx) but the result is same.

Make sure you have the correct configuration parameters like baud rate, parity bit, start bit, stop bit.

Also make sure you have the right COM port selected.

The baudrate and parity is same

verify COM port

I have checked the port com is same

Maybe its just bad?
