Chapter 7: Off-Line Node Recovery
Overview
The MSR312P base module is equipped with a function known as Off-Line Node Recovery. Off-Line Node Recovery is used
mainly to commission a device on a network. When a new product is put on the network, it is at a default address of Node 63. If
multiple units are placed on a network without first using node commissioning to change the node address a duplicate MAC ID
error occurs. This means that more than one device is located at the same node address and only one of them is allowed online.
Off-Line Node Recovery now allows you to recover the faulted devices and change the node address. This is a powerful tool
because multiple nodes can be put on the network on installation and recovered one at a time without having to continually reset
the network. The following section will walk through a sample recovery.
Note: If the MAC ID is set through the rotary switches, Off-Line Node Recovery will not be able to recover the faulted device
because it cannot change the node address.
Sample Recovery
This example has placed two MSR312P base modules on a network at the same node address 63.
