Pin Arrangement Of Communications Connectors On The Profinet Coupler Unit - Omron PROFINET NX-PNC202 User Manual

Precautions for Safe Use
• Double-check all switches and other settings and double-check all wiring to make sure that
they are correct before turning ON the power supply. Use the correct wiring parts and tools
when you wire the system.
• Do not exceed the ranges that are given in the specifications for the communications dis-
tance and number of connected Units.
Precautions for Correct Use
• The maximum length between nodes is 100 m. However, some cables are specified for less
than 100 m. Generally speaking, if the conductors are twisted wire rather than solid wire,
transmission performance will be lower, and reliable communications may not be possible at
100 m. Confirm details with the cable manufacturer.
