Software Interface Chapter 3
Device and Group ID
Device ID and Group ID can be directly read respectively in registers 220 and
221. They can be modified by registers 347 (Device ID) and 348 (Group ID).
Network Channel
The Network Channel can be read in register 224 and overwritten into register
351 by any value between 11 and 26.
Sampling Interval
This interval time is the maximum period for a heartbeat to be sent by any node,
when no data is transmitted within that period, in order to indicate that the
device is still online. The sampling interval is expressed in tenths of seconds from
0…65,535 (65,535 = 109 minutes), read from register 222 and written into
register 349.
The PowerMonitor W250 unit uses a default value of 30 s (value 300).
ATTENTION: The Group ID and Device ID should not be modified except under
exceptional circumstances. One such circumstance would be operating two or
more independent PowerMonitor W250 networks in such close proximity that
RF interference with each other occurs. Please contact Rockwell Automation
support services for more information or if assistance is required.
IMPORTANT The Network Channel should not be modified except where interference with
other RF communication occurs. Please contact Rockwell Automation support
services for more information or if assistance is required.
ATTENTION: Modifying the Network Channel may result in loss of
communication between the device and the network. This will require return of
the device to Rockwell Automation for factory service.
