CGCM-DLR Unit Software Interface
Chapter 6
For instance, a 30 MVA machine operating at 10% load yields an energy tag limit
of:
(8,338,600 * 0.1 * 30000) = 25,015,800,000 kVAh, or 2.50158 x 10
10
kVAh
When the energy tag value exceeds 8,338,600, rounding of the value begins to
occur.
The energy values are not retentive. When the CGCM-DLR unit powers up or
re-establishes a connection with the controller, the energy presets in the
Unscheduled Write table are written to the energy metering values.
