Omron NT631C manual Connecting to a C-series Host Link Unit Settings at The Host, Switch Setting

Connecting to the RS-232C Port at the Host Section 4-1

*2 Use a CPM2C-CN111 or CS1W-CN114/118 Connecting Cable, CPM1-CIF01 RS-232C Adapter, or CPM1- CIF11 RS-422A Adapter to connect.

*3 The CQM1H-CPU11 does not have a built-in RS-232C port, so connect to the peripheral port to the PT with a CS1W-CN118 Connecting Cable.

*4 CPU Units of CVM1/CV-series PLCs without the suffix -EV@cannot be connected.

Connecting to a C-series Host Link Unit

Settings at The Host

When using the host link method, the settings shown below must be made at the host (depending on the Unit, some of these settings may not be neces- sary, or settings not shown here may be necessary).

Item	Switch Setting
I/O port	RS-232C
Communications speed	Set the same speed as for the NT631/NT631C. (*1)
Transfer code	ASCII, 7 data bits, 2 stop bits
Parity	Even
1-to-1/1-to-N	1-to-N(*2)
Instruction level	Level 1, 2, 3
Unit #	00

Set the host link communications speed at 9600 bps or 19200 bps with the memory switch at the NT631/NT631C. For details, refer to 6-7-2 Setting the Host Link Method (page 155).

The 1-to-N setting enables BCC (Block Check Character). It is not actually pos- sible to connect more than one NT631/NT631C in a single host link.

The setting methods for each type of Unit are described in the following.
