MXP Diagnostic Terminal

8.1.6.4DP Command (Diagnostic Poll)

This command lists all the devices found (irrespective of the MX4428 programming) by issuing a command to each side of the loop (left and right) which requests all devices to identify themselves. Thus it can be used to find what devices are present on the loop and which devices are found from each end, if the loop is broken or isolator bases have opened. This can help identify which section of the loop cable is broken or shorted.

It will list devices found with any address including addresses above 200. If two or more devices are present with the same address they will usually be detected, however their replies may collide resulting in neither being detected. Therefore a second attempt is made on each line in order to maximise the chance of locating multiple devices with the same address. On the second attempt, only devices not found on the first attempt are displayed.

This command is a local version of the MX4428 DP command.

The DP command will note as “foreign” any devices which are found but not currently programmed. However it will not display devices which are programmed but not found. Other messages may be given, e.g. “Duplicate Device”, “Unknown Type”, “Used as Heat only”, “Used as MIM”, “Type Mismatch”.

8.1.6.5CA Command (Change address)

The change address command may be used to change the address of a single device (the first number) on the analog loop to a new address (the second number). If devices are added one at a time, this command may be used to assign their addresses instead of using the programming tool. New devices from the factory normally have an address of 255.

Both new and old addresses may be any number greater than 0 and up to 255. Addresses between 201 and 255 will be inaccessible to the MX4428.
