A slot number of the source of this event.
The Message String
The message string is defined in the card and is therefore fixed. It
may be used in controlling software like Synapse Setup to show
the event.
The Tag
The tag is also defined in the card. The tag has a fixed meaning.
When controlling or monitoring software should make decisions
based on events, it is easier to use the tag instead of interpreting a
string. The first implementation is the tag controlled switch in the
GPI16.
In cases where the event marks a change to fault status (e.g. 1 for
Loss of Input) the complement is marked by the tag increased by
128 (80
hex
) (e.g. 129 (81
hex
) for Return of Input).
Defining Tags

The Priority
The priority is a user-defined value. The higher the priority of the
alarm, the higher this value. Setting the priority to Zero disables
the announcement of this alarm. Alarms with priorities equal or
higher than the Error Threshold setting of the RRC will cause the
error LED on the Synapse rack front panel to light.
The Address
Together with the message string or the tag, the slot number or
address of the card is relevant to be able to assign the event to a
certain card.
