3.12.9.7 Blocking of the Trip Commands
The trip commands can be blocked via parameters or an appropriately
configured binary signal input. This blocking is then effective for all four trip
commands. The trip signals are not affected by this blocking. If the trip
commands are blocked, it is indicated by the continuously illuminated amber LED
indicator H 2 on the local control panel and by a signal from an output relay
configured to “Blocked/Faulty”. (To identify H 2, see the dimensional drawings in
the
Chapter 4, (p. 4-1) .)
3.12.9.8 Counter of Trip Commands
The number of trip commands is counted. The counters can be reset either
individually or as a group.

3.12.10 Time Tagging and Clock Synchronization
The data stored in the operating data memory, the monitoring signal memory
and the event memories are date- and time-tagged. For correct tagging, the date
and time need to be set in the P631.
The time of different devices may be synchronized by a pulse given to an
appropriately configured binary signal input. The P631 evaluates the rising edge.
This will set the clock to the nearest full minute, rounding either up or down. If
several start/end signals occur (bouncing of a relay contact), only the last edge is
evaluated.
