Reference ￿If unit numbers 8 and 9 are set with a C￿￿H, a “special I/O unit error” occurs.

When an NT600S is connected to a C H, I/O expansion equipment cannot 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.

3-7-2 Connection Method

Using the I/O connecting cable, connect the C200H interface unit mounted to the

NT600S and the PC unit.

Caution 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.

	Model	Cable length (L)
	C200H-CN311	30cm
	NT20M-CNP711	70cm
	C200H-CN711
For connecting C200H/	NT20M-CNP221	2m
	C200H-CN221
HS/HE/HG/HX
	NT20M-CNP521	5m
	C200H-CN521
	NT20M-CNP131	10m
	C200H-CN131
	C20H-CN312	30cm
	NT20M-CNP712	70cm
For connecting C H	C20H-CN712
	NT20M-CNP222	2m
	C20H-CN222

Caution

Note

In the case of NT20M-CNP￿￿￿models, the connector at the C200H interface 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￿￿H models).

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￿￿￿is used as the I/O connection cable, the connector will project beyond the bottom face of the NT600S.
