UPS power failure monitoring

The Sensor Input Module (SIM8F) stores the measured and derived time related
statistics information in its non-volatile memory. After the SIM8F module reboots or
is powered up, the stored information is used to continue the updating of measured and
derived statistics.
SIM8F aims at storing and recovering the information stored in its non-volatile
memory. After a sudden loss of power supply to RIO600, data can be corrupted in the
non-volatile memory of the SIM8F module. This leads to the loss of stored
information. All time related information used for statistics is lost and statistics
calculation restarts.
To avert the loss of data, the UPS power failure output signal from UPS should be
connected to any one of the DIM8H/L input channels or the subscribed Boolean
GOOSE data set element can be used as an indication for UPS power failure. When the
binary input is detected by the DIM module or the Boolean value in the subscribed
GOOSE data set element is set to "TRUE", it is considered as an indication of UPS
power failure and SIM8F stores the statistics information in its non-volatile memory.
This guarantees successful storage of statistics information in SIM8F module's
memory and the statistics calculations resume from this point after a reboot. If UPS
power failure indication indicates that the UPS power is healthy, SIM8F continues its
normal operation.
The UPS power failure input channel for DIM8H/L module can be configured in
Signal Matrix in PCM600.
