Retrieving Breaker Status and Operation Counter Information
Current breaker status can be read from HMI Screen 1.5.6 and through the communication ports using
the RG-STAT command. The General Status Reporting subsection provides more information about this
command.
The number of breaker operations can be read at HMI Screen 4.3.1. The counter value can be adjusted
using the Edit key. This allows the relay counter value to be matched to an existing mechanical
cyclometer on a breaker mechanism. Write access to the reports functions must be gained to edit this
value at the HMI. Breaker operations can be read or set through the communication ports using the RB-
OPCNTR (report breaker, operations counter) command.
The breaker operations counter can be monitored to give an alarm when the value exceeds a threshold.
See Breaker Alarms, in this section for more information about this feature.
Breaker operations can also be read using the RB command. The RB command returns the number of
breaker operations and breaker contact duty information.
Breaker duty monitoring is discussed in the following paragraphs.
