2-3 How to connect to Ethernet

The Ethernet unit employs 10BASE-T specifications, so the controller connects by a cable to the HUB.

Use UTP cables (unshielded twisted-pair cables) or STP cables (shielded twisted-pair cables) for category 3 or higher, with straight-through wiring specifications.

To connect to the Ethernet, insert the cable with modular jack into the modular connector on the controller until you hear a click. Insert the other end of the cable into the modular connector on the HUB.

!CAUTION

We use an FL HUB (made by Phoenix Contact) to check operation. Using this HUB is recommended if constructing your own system.

HUBs generally available on the market are not designed for use in locations such as factories, so some HUBs are vulnerable to external noise. Please acknowledge beforehand that operation cannot be guaranteed if other types of HUBs are used. Always be sure to use a HUB with high noise resistance when connecting to the controller.

!CAUTION

The maximum cable length between the HUB and controller is 100 meters. Before connecting the HUB and controller always refer to the instruction manuals for the device used by the other party and peripheral equipment such as the HUB. If the HUB communication mode can be set manually, then set to 10Mbps/Half Duplex.

Using a straight-through cable is recommended when connecting to the other party’s device by way of the HUB. You can connect directly to the other party’s device without the HUB by using a crossover cable but communication may sometimes not be possible due to the type of LAN adapter used by other party’s device.
