Connecting an NT631/NT631C and Host
118
Direct Connection between RS-485 Ports at Both Units
Reference:
The connection method in which the RS-485 ports of an NT631/NT631C and
a host are connected is described here.
When RS-485 is used at the PT side, only the NT Link (1:N) method (standard
or high-speed) can be used.
Wiring When Connecting a CS-series Serial Communications Board, CS/
CJ-series Serial Communications Unit, C-series C200HX/HG/HE(-Z)E
Communications Board, or CQM1H Serial Communications Board
Applicable Units:
For details on handling shield wires, refer to 5-2-8 Handling the Shield on RS-
422A/485 Cables on page 125.
Note A Serial Communications Board cannot be installed.
