Communicating with the PC Using C200H Direct Communication
Section 2-7
2-7-2
Connection Method
Connect the NT20S and PC.
The connection conditions are different for C200H/HS, C200HX/HG/HE and
C
jj
H.
Caution:
S
Always turn off the power at the PC and PT before connecting the C200H inter-
face cable. Otherwise the system may operate unpredictably.
S
After connecting the communication cable, always secure it with the screws.
Otherwise the cable may disconnect, causing operation to fail.
[I/O connection cable]
Use the following models of I/O connection cable.

The C200H interface side connector of NT20M-CNP
jjj
has been down-
sized.
Caution:
S
Keep the total length of I/O cables used within 12 m (6 m for C
jj
H).
S
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.
Reference: If a C200H-CN
jjj
or C20H-CN
jjj
is used as the I/O connection cable, the
connector will project beyond the bottom face of the NT20S.
If the I/O cable is passed through a hole or other opening, the hole or opening must
be at least 53 mm
φ
. Removing the top cover reduces this requirement to 33 mm
φ
or larger. During installation, this cover must be replaced before securing the PT.
