Precautions for Correct Use
• Always use an Ethernet switch for tag data links in the network.
If EtherNet/IP tag data links (cyclic communications) are used with a repeating hub, the com-
munications load on the network will increase. This will increase collisions and may prevent
stable communications.
• Do not bend the communications cables past its natural bending radius or pull on it with
excessive force.
• Do not place heavy objects on top of the communications cables or other wiring lines. Doing
so may cause the wire disconnection.
• Do not exceed the communications distance that is given in the specifications and use the
specified communications cable.
• Make the following settings for the switching hub used to connect the Main Unit. Set the
switching hub connected to the Main Units as follows.
• In tag data links, when a network system is constructed together with a node for which multi-
cast communications settings have been made, a tag data link timeout may occur. Block the
multicast by using a switching hub having a multicast block function so that multicast packets
do not reach the main K6PM-TH Unit. (The OMRON W4S1 series does not have the multi-
cast block function.)
