Runtime counter for machines and devices MDSOPT provides history data since the
last commissioning. The counter counts the total number of generator running hours
and is incremented when the energizing circuit breaker is closed.

The main purpose of the synchronism and energizing check SECRSYN is to provide
control over the closing of the circuit breakers in power networks to prevent the
closing if conditions for synchronism are not detected. The energizing function allows
closing, for example, when one side of the breaker is dead.
SECRSYN measures the bus and line voltages and compares them to set conditions.
When all the measured quantities are within set limits, the output
SYNC_OK
