About this task

Metasys expansion modules are devices on MS/TP (FC or SA) buses. Before you operate expansion modules on a bus, you must set a valid and unique device address for each expansion module on the bus. You set the XPM device address by setting the positions of the Device Address rotary switches at the top of the expansion module.

The following table describes the valid rotary switch device addresses for communications bus applications.

4-127
Note: Addresses 0-3 are reserved and not for use on expansion modules.
ZFR Pro wireless communication 4-127
Note: Addresses 0-3 are reserved and not for use on expansion modules.

The device address is a decimal address that is set using three rotary switches located at the top of the expansion module. The numbers are ordered from left to right, 100s, 10s, and 1s when the expansion module is oriented as shown in Physical features. In the following figure, the switches are set to 1 2 3, designating this expansion module's device address as 123.

The device address must match the device address defined in the Controller Configuration Tool (CCT) under Define Hardware > Network Settings.

To set the device addresses on XPM expansion modules, complete the following steps:

Procedure

  1. Set a unique and sequential device address for each of the devices connected on the FC or SA Bus, starting with device address 4.
  2. To ensure the best bus performance, set sequential device addresses with no gaps in the device address range (4, 5, 6, 7, 8, 9, and so on). The devices do not need to be physically connected on the bus in their numerical device address order.
  3. Write each expansion module's device address on the white label below the device address rotary switch block on the expansion module's cover.

    Refer to the MS/TP Communications Bus Technical Bulletin (LIT-12011034) for more information about device addresses and how to set them on MS/TP buses.
