17. If communications are adversely affected by noise from the Unit’s power

supply terminals, the problem may be solved by implementing the mea-
sures shown below.

a) Add to the communications retry processing at the application. In par-

ticular, noise resistance capacity can be improved by increasing the
number of retries for applications using UDP.

b) Insert a noise filter right next to the Unit’s power supply terminals.

The following table shows the power supply specifications. Make sure that
these specifications are met.

OMRON’s S82J Series is recommended for the power supply.
