Thank you for your reply.

Thank you for the response. Copy from manual: NS-series RS-485 (two-wire) communications are used to connect to an OMRON Temperature Controller. The NS-AL002 cannot be used with the NT-series PTs or PLCs. Always use RS-422A (four-wire). There is no other way i can use a 2-wire cable?

Hello all, Is there any way to connect 1 (one) CJ1M-CPU13 with 2 (two) HMI NS-15TX using a 2-wire cable? Thank you in advance for your help.
