Can NS-series and NT-series Programmable Terminals be used together on one RS-232C port or one RS-422 port on a Programmable Controller?


Yes, it is possible if you use 1:N NT Links. It is done the same way as wiring or settings for NS-series or NT-series only.
However, 4-wire RS-422 must be used.

NS-series do not support RS-485 (two-wire). Also, when an RS-232C port on the Programmable Controllers is used, NT-AL001 RS-232C/RS-422 Link Adapter is necessary.
