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.
