Section 1-3
Host link and NT link (1:1) communications can be performed with RS-422A by
using an RS-232C/RS-422A converter unit (type NT-AL001), but communica-
tions with RS-485 are not possible. For details on the wiring for RS-422A, refer to
“Appendix F Connecting to an RS-232C/RS-422A Converter Unit” (page 275 of
the appendix).
NT Link (1:N) Systems
When NT600S is connected to a PC in a 1:N connection, use an RS-232C cable
and RS-422A/485 cables.
Personal computer (support tool)
Connected to the NT600S when necessary to
transmit created screens to the NT600S
screens and set NT600S settings.
Personal computer: IBM PC/AT or compatible
Support tool: NT-ZA3AT-EV2
OMRON PC
Controls the NT600S as required
during machine control, line
monitoring, etc.
C200HX/HG/HE can be used.

NT600S
In an NT link (1:N), up to
eight NT600S units can be
connected to one PC port.
NT600S
In addition to applications such as monitoring
production lines and displaying messages such
as instructions transmitted to the workplace,
also notifies the ON/OFF status of switches and
numerical input to the PC.

When connecting the C200HX/HG/HE and an RS-232C/RS-422 converter unit,
use a converter unit whose lot number is 15Y5 or later. Converter units of lot num-
bers previous to 15Y5 cannot be connected.
