The blocking of the function causes an HMI display event and a time-stamped blocking event with
information of the startup values of the selected signal and its fault type to be issued.
The blocking signal can also be tested in the commissioning phase by a software switch signal when
the relay's testing mode "Enable stage forcing" is activated (
General
→
Device).
The variables the user can set are binary signals from the system. The blocking signal needs to reach
the device minimum of 5 ms before the set operating delay has passed in order for the blocking to
activate in time.
Events and registers
The programmable stage function (abbreviated "PGS" in event block names) generates events and
registers from the status changes in START, TRIP, and BLOCKED. The user can select which event
messages are stored in the main event buffer: ON, OFF, or both.
The events triggered by the function are recorded with a time stamp and with process data values.
