How does the Yokogawa 3000 system’s 121 card communicate with the Conixion SIS? We are using a two-wire connection; what settings need to be made on the 121 card side of the Yokogawa 3000 system? Urgent!

Yokogawa 121 communication card and Conexant communication issues

Reply #22018-04-20

Baud rate, parity, data bits, stop bits, and then the address of the communication node

Could you explain it in detail? I want to know exactly what to do

It’s mainly the address of the communication point – I don’t know how to fill it in. I asked engineers from other factories, and they said to use A40020, but I have no idea what that means! Now, after setting the Yokogawa 121 card, the lower unit display shows fail, with the error code being 1C. I don’t know how to do it
