6.8 Wiring of Ethernet Cable
Connecting the Ethernet cable to the I/O module (except for waterproof module)
■Connecting
1. Power off the module power supply of the I/O module (except for waterproof module) and the power of the external
device.
2. Push the Ethernet cable connector into the I/O module (except for waterproof module) until it clicks. Pay attention to the
connector's orientation.
3. Power on the module power supply of the I/O module (except for waterproof module).
4. Power on the external device.
5. Check that P1 LINK LED/P2 LINK LED on the port into which the Ethernet cable is connected is on.
*1*2
If P1 LINK LED/P2 LINK LED does not turn on, refer to the following and take a corrective action.
Page 195 When the P1 LINK LED or P2 LINK LED turns off
*1 The time taken for P1 LINK LED/P2 LINK LED to turn on after connection of the Ethernet cable may vary. The LINK LED normally turns
on in a few second. However, if link-up processing is repeated due to a condition of a device on the line, the longer time may be
required.
*2 When the communication speed of the I/O module is 100Mbps, and when connecting a 100Mbps device to P1 and P2 of the I/O module,
enable auto-negotiation of that device.
Both P1 and P2 connectors can be used.
• To use only one of them for star topology, either P1 or P2 can be connected.
• To use both of them for line topology and ring topology, P1-P1, P2-P2, and P1-P2 connections are possible.
■Disconnecting
1. Power off the module power supply of the I/O module (except for waterproof module).
2. Press the latch down and unplug the Ethernet cable.
