Address Management for Ethernet Modules

Introduction

CAUTION

UNINTENDED EQUIPMENT OPERATION

If two devices have duplicate network addresses, you can not predict the operation of the equipment.

Failure to follow these instructions can result in injury or equipment damage.

You must carefully manage the modules’ IP addresses because each device on the network requires a unique address.

MAC Address

General case

This address is unique for each Ethernet module. It is defined in the factory by the module manufacturer.

Exception

For the TSX ETY 110 module, this address is derived from the X-Way address using the code selectors situated on the front panel of the module.

It is defined in the following way: 00.80.F4.00.<network number>.<station number>

NOTE: Given the risk of possible duplicate addresses, you must ensure that it conforms to the company’s addressing scheme.

IP Address

General case

You define this address yourself when configuring the module. On the same local network, this address must be unique.

Exception

For the TSX ETY 110 module, this address can be derived from the MAC address.

For the TSX ETY 110, TSX ETY PORT, and TSX ETY 5103 modules and the Ethernet link of the TSX 57 5634/4634 and, in the absence of confirmation by Control Expert, this address is, by default, derived from the MAC address.

X-Way Address

General case

All devices have an X-Way address linked to the IP address by the module configuration. This address must be unique within the entire X-Way architecture.

Special Cases

For the TSX ETY 110 module, the X-Way address is defined using the code selectors on the module. These selectors code the network number and the station number.

The Ethernet link built into the processors does not require an X-Way address.
