Allen-Bradley Powermonitor II Unit
Remote I/O, Ethernet and serial communication are supported. The Powermonitor II must
be at firmware version 3.00 or later and set up to use either the 16 parameter or 3 and 7
parameter snapshot log.
Allen-Bradley Powermonitor Unit
The power monitor's snapshot log holds up to 50 records. Remote I/O communication is
supported.
Allen-Bradley MicroLogix EEM (1803-EEM) Module
The MicroLogix EEM trend log contains an accumulated energy counter and a demand
value for each configured meter.
Allen-Bradley Programmable Controllers
ControlLogix, CompactLogix, MicroLogix, SLC 500, and PLC-5 controllers support
ADR when programmed with specific logic. The ADR Wizard for RSLogix software is
used to develop the specific logic that supports ADR.
Set up ADR for Power Monitor Units
Follow these steps to set-up ADR for a power monitor unit.
1. Set up the power monitor or EEM snapshot, energy, data, or trend log (depending on
the power monitor model) to log the desired parameters at a rate equal to the log rate
of the meter tags.
2. During device setup, enable ADR by selecting the check box.
During meter tag setup, the correct snapshot or trend log parameter value is
automatically selected based on the value type you select for the meter type. If this
does not occur automatically, please refer to the power monitor user manual for the
value of the log parameter number, and enter the number in the meter tag setup page.
Snapshot log energy data is expressed with 7 digit precision
while real-time energy data is expressed with 15 digit precision.
ADR used with the Powermonitor II may result in inaccuracies in
energy consumption and billing reports, especially if the
repopulated data occurs at the beginning or end of the reporting
period.
ADR for legacy power monitors may conflict with other
applications which read the trend or snapshot logs at the same
time. Examples of these applications include RSPower32 and the
RT device viewer, logs tab. To reduce the likelihood of conflicts,
temporarily disable ADR when reading the power monitor trend
or snapshot log by using one of these applications.
