3. Type any number between 1 and 31.
4. Press [ENTER] and cycle power to the processor.
Assign other node addresses in the same manner until all of your processors have a
unique node address.
Note You cannot change the node address of the terminal at this display. If you try, the
message
CURRENT DEVICE IS NOT A PROCESSOR appears.
Consequences of Changing a Processor Node Address
Remember that the processor node address resides in the status data file (word
S:15) of a processor file. This means that when you overwrite the contents of
processor memory by using the Restore or Memory Transfer function, the node
address may change as follows:
Restore
Ć When you restore a processor file, then cycle processor power, the node
address of the restored processor file will take effect, overwriting the previous node
address.
Memory Transfer
Ć When you transfer a processor file from a memory module to
the processor, then cycle processor power, the node address of the transferred file
takes effect, overwriting the previous node address.
Note If the processor node address is unknown, immediately after you restore (download)
a processor file or transfer a processor file from a memory module to the processor,
select [F8] Node Address from the Who Active table and re-enter the current node
address. Failure to do this can result in a duplicate or incorrect node address after
you cycle power to the processor.
Setting the Processor Maximum Node Address
If a processor is the highest numbered node, access the Who Active display to set
the maximum node address. For the most efficient network operation, we
recommend setting the maximum node address of the highest numbered node equal
to the highest node address (total number of devices) used on the network.
Note If you set the maximum node address of the highest node you are using to its own
address, a higher numbered node is prohibited from being added to the network.
