5.3.8 I/O Terminal Modules: Communication Cables and
Power Distribution
Use only the specified cable when connecting to terminal modules. Use of any
other cable may cause communication errors.
Transmission distance by cable type
AWG18 twisted pair or VCTF 0.75 mm 2 120 m (Total length)
AWG16 twisted pair or VCTF 1.25 mm 2 120 m (Total length)
RG-58 coaxial or 3D-2V 200 m (Total length)
Connection patterns
Connections and branching between remote I/O terminal modules can be arranged
as desired; however, the total length of the wiring must not exceed that specified
above.

* You can use either wire of the twisted pair
for S+ or S-. Also, you can use either the
core cable or the braided cable.
However, do not change the combination in
the system.
• Use only the specified cable when connecting to terminal modules. Use of
any other cable may cause communication errors.
• The cable can be selected from the three types shown above.
However, use only one type in a system. Mixing more than one type may
cause a malfunction.
