(*) CODESYS EtherExpress driver for EtherCAT is installed at the factory.
To use different interfaces than the ones set up at the factory, update the network driver.
For information about how to update the driver, see “2.3 Updating the Network Driver”.
For information about the location of the LAN port connectors, refer to “1.5 Name and
Function of Each Part” in the HF-W instruction manual.
(2) LAN cables
In “5.8 Interface Specifications” in the HF-W instruction manual, UTP cables are
recommended for use in connection to LAN ports. In spite of that, we recommend using
cables with the following specifications if the cables are used for EtherCAT connection
on HF-W100E/IoT.
Cable specification: STP cable (shielded twisted-pair cable) category 5e or better
[Caution]
When an STP cable is used, the grounds of the devices at both ends must be at the same voltage
level.
