Section 13-1
13-1 Maintenance and Replacement
This section describes the routine cleaning and inspection recommended as
regular maintenance, as well as the Unit replacement procedure required if an
EtherNet/IP Unit needs to be replaced.
13-1-1 Cleaning
Clean the EtherNet/IP Unit regularly as described below in order to keep the
network in its optimal operating condition.
• Wipe the Unit daily with a dry, soft cloth.
• When a spot can’t be removed with a dry cloth, dampen the cloth with a
neutral cleanser (2% solution), wring out the cloth, and wipe the Unit.
• A smudge may remain on the Unit from gum, vinyl, or tape that was left on
for a long time. Remove the smudge when cleaning.
!Caution
Never use volatile solvents such as paint thinner, benzene, or chemical wipes.
These substances could damage the surface of the Unit.
13-1-2 Inspection
Be sure to inspect the system periodically to keep it in its optimal operating
condition. In general, inspect the system once every 6 to 12 months, but
inspect more frequently if the system is used with high temperature or humid-
ity or under dirty/dusty conditions.
Inspection Equipment
Prepare the following equipment before inspecting the system.
Normally Required
Equipment
Have a standard and Phillips-head screwdriver, multimeter, alcohol, and a
clean cloth.
Occasionally Required
Equipment
Depending on the system conditions, a synchroscope, oscilloscope, ther-
mometer, or hygrometer (to measure humidity) might be needed.
Inspection Procedure
Check the items in the following table and correct any items that are below
standard.
13-1-3 Unit Replacement Procedure
Replace a faulty EtherNet/IP Unit as soon as possible. If the built-in EtherNet/
IP port is faulty, replace the CPU Unit as soon as possible. We recommend
having spare Units available to restore network operation as quickly as possi-
ble.
Precautions
Observe the following precautions when replacing a faulty Unit.
• After replacement, verify that there are no errors with the new Unit.
• When a Unit is being returned for repair, attach a sheet of paper detailing
the problem and return the Unit to your OMRON dealer.
