2.2.6 PROTECTION EVENTS
The IED logs protection starts and trips as individual events. Protection events are special types of standard
events.
The event type description shown in the Event Text
cell for this type of event is dependent on the protection
event that occurred. Each time a protection event occurs, a DDB signal changes state. It is the name of this
DDB signal followed by 'ON' or 'OFF' that appears in the Event Text cell.
The Event Value cell for this type of event is a 32 bit binary string representing the state of the relevant DDB
signals. These binary strings can also be viewed in the COMMISSION TESTS column in the relevant DDB
batch cells.
Not all DDB signals can generate an event. Those that can are listed in the RECORD CONTROL column. In
this column, you can set which DDBs generate events.
2.2.7 SECURITY EVENTS
An event record is generated each time a setting that requires an access level is executed.
The event type description shown in the Event Text
cell displays the type of change. These are as follows:
