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.
