Obtaining the Modbus Register Map

58 EATON Power Xpert
In Figure 34, Breaker 01 is a three-phase, 20A breaker and occupies
three positions (1, 2, and 3). Data returned from Breaker 01 contains the
data associated with all three phases. The next breaker is Breaker 04
(because Breaker 01 occupies three positions). Breaker 07 is a two-
phase, 20A breaker. A request for data from Breaker 07 returns data
covering Phases A and B. A single-phase, 60A breaker is shown in
position 9. Data returned from Breaker 09 contains only data from
Phase C. Position 12 is unoccupied.
The breaker map for your specific RPM is available from the card's Web
page (see the following section, "Obtaining the Modbus Register Map").
Attempting to read data from a nonexistent breaker results in an error
code. For example, requesting the Phase B voltage from ganged
Breaker 05 results in a returned error code. The Phase B voltage from
the ganged breaker is obtained by reading Breaker 04.
Sometimes it is advantageous to address the individual poles of a
breaker instead of a ganged breaker, which returns data for all the poles
in the breaker. The individual poles can be addressed using the Unit IDs
for EMS Pole Data or RPM Pole Data as shown in Table 2 beginning on
page 63.
To obtain a comma-separated values (*.csv) file, see the following
section, "Obtaining the Modbus Register Map," and select the pole data
when prompted from a device.
NOTE Either EMS Pole Data or RPM Pole Data register maps are available on the Web
page, depending on the product type, but not both.
NOTE The Modbus file is a comma-separated values (*.csv) file that can be opened in
Microsoft Excel software. Some computer configurations will automatically open the files in
the Microsoft Excel software instead of prompting you to save.
