Addressing Expanders

The Expander Addressing option is used to view the hardware connected to the system network and to set the addresses of DIN rail modules which have auto-addressing capability. This page displays the details of all modules currently connected or those that have registered previously but may currently be offline.

Listed for each module is:

  • The module type
  • The serial number
  • Current firmware version
  • The current address of the module
  • Whether the module is registered with the controller
  • Whether the module is currently online

When connecting a module to the network it must be added to Protege WX and allocated a unique physical address. By default all DIN rail modules are shipped from ICT with the address of 254 and without changing this address the module will not be able to register with the controller.

For older legacy PCB modules, the address is configured via DIP switches. Refer to the relevant Installation Manual for instructions on configuring the address of the module.

To Set the Network Address of a Module:

  1. Ensure the controller is correctly powered.
  2. Connect the module(s) that require addressing to the module network. Make sure that the power light on each module is on and that the status light begins flashing rapidly.

  3. Allow some time for the module(s) to attempt to register with the controller.

    • If the module has the default address of 254 or has the same address as another module, the fault light will be constantly on and the status indicator will be flashing red with an error number.

      • For an unaddressed module, the status indicator will flash in three flash bursts.

      • If the address is already in use by another module, the status indicator will flash in four flash bursts.

    • If the module has been previously addressed and is not a duplicate, then it will succeed in registering and the status light will begin flashing at 1 second intervals.
  4. Once all modules have completed the registration process (successful or not), open the module addressing window by selecting Expanders | Expander Addressing.
  5. Enter an address for the relevant module(s) by selecting an option under the Address column then click Save to save the address and restart the module.

  6. Allow around 5 seconds per module for the new address to be sent and registered then click Refresh to update the list and display the new addresses.

    • If the address has not changed, check that the module is online and communicating and has finished attempting to register.
    • If the address has changed but the module is not shown as registered, check that the address is in the valid address range and is not a duplicate of another modules address.

Once all modules are online and registered with the desired addresses, the addressing process is complete.
