If unit numbers 8 and 9 are set with a C

When an NT600S is connected to a C
be connected. In other words, it will not be possible to connect other special I/O
units, and therefore whatever unit numbers are specified there will be no du-
plication of numbers.
Using the I/O connecting cable, connect the C200H interface unit mounted to the
NT600S and the PC unit.

Always turn off the power at both the PC and PT before connecting the C200H
interface cable.
Otherwise the system may operate unpredictably.

Switch off the power to the NT600S and PC before disconnecting/connecting
the cable.
[I/O connecting cable]
Use one of the following models of I/O connecting cable.
For connecting C200H/
HS/HE/HG/HX HS/HE/HG/HX





For connecting C For connecting C H H
In the case of NT20M-CNP
side is a compact one.

The combined lengths of each of the I/O connecting cables must not exceed a
total of 12 m (or 6 m for C

The cable's tensile load is 30 N. Do not subject it to loads greater than this.
Otherwise a discontinuity may occur, causing operation to fail.

If the I/O connecting cable is passed through a hole, this hole must have a diam-
eter of at least 53 mm
. If the top cover is removed the cable can be passed
through a minimum hole size of 33 mm
. Replace the cover before mounting
the unit.




If a C200H-CN or C20H-CN
the connector will project beyond the bottom face of the NT600S.
