Omron Companies shall not be responsible for conformity with any standards, codes or regulations
which apply to the combination of the Product in the Buyer’s application or use of the Product. At
Buyer’s request, Omron will provide applicable third party certification documents identifying ratings
and limitations of use which apply to the Product. This information by itself is not sufficient for a com-
plete determination of the suitability of the Product in combination with the end product, machine, sys-
tem, or other application or use. Buyer shall be solely responsible for determining appropriateness of

Precautions for Correct Use

Precautions for Correct Use
Be sure to observe the following precautions.
Communications
• Communications setup is necessary for installation and replacement. Make communication set-
tings according to this manual.
• Follow the instructions in this manual for connection method and cables to be used with the Ether-
Net/IP or the Modbus TCP. Otherwise, communication failure may occur.
• Do not exceed the communications distance that is given in the specifications.
• If EtherNet/IP tag data links (cyclic communications) are used with a repeating hub, the communi-
cations load on the network will increase. This will increase collisions and may prevent stable
communications.
Communications Cables
• Do not pull on the communications cables or bend the cables beyond their natural limit. Do not
place heavy objects on top of the communications cables or other wiring lines. Doing so may
cause the wire to break.
• To avoid inductive noise, keep the communications cables away from power cables carry high
voltages or large currents. Also, do not wire power lines together with or parallel to product wiring.
• If no communication cable is connected, attach a dust cover.
• Depending on the ambient temperature or the load ratio, the product itself may have a high tem-
perature. In that case, do not insert or remove the communications cable. Otherwise, minor burns
may occasionally occur.

1-6 Self-Diagnosis Information
This section shows status information that can be confirmed by the self-diagnosis of the S8VK-X.
The following self-diagnosis status can be checked with the "S8VK-X status" using the EtherNet/IP or
the Modbus TCP.
Note 1. The cause of the " " and " " display may be the noise from outside.
2. When " " is displayed, the display can not be switched.
3. The causes of " " and " " display may include use in conditions exceeding the derating curve,
ventilation error, or an error in the installation direction.
4. When you press the Indication switching/reset key with " " or " " displayed, the display will
return to the normal display.
5. When " " is displayed, the display of the number of years and percentages until the replacement
time will be years and %, respectively.
