Events and registers
The volts-per-hertz overexcitation protection function (abbreviated "VHZ" 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 function offers
one (1) stage which can be set to definite and/or inverse operating time characteristic.
The events triggered by the function are recorded with a time stamp and with process data values. The
function registers its operation into the last twelve (12) time-stamped registers.
