4.3.6 EVENT CONFIGURATION (Cont.)
OPERATOR
This allows a logical combination of input sources to be used to trigger an event. The selections and their definitions
are shown in table 4.3.6, below.
Table 4.3.6 Logical operators for event sources
SOURCE 2 SENSE
Allows source 2 to be used in its normal sense (Select 'Source 2') or inverted (Select 'Not Source 2').
Example: Source 2 is Group 1 Batch Running
With Source 2 Sense = Source 2, the event is active whilst the batch is running.
With Source 2 Sense = Not Source 2, the event is active whilst the batch is not running.
DESCRIPTOR
Allows a text string to be entered as the event title. See
JOB NUMBER
Select the required job number for this event.
CATEGORY
Select the required job to be carried out when the channel is in alarm (e.g. Drive relay) See
tion of job categories.
WHILE/ON
Allows the action of the alarm job to be chosen as
a.
whilst active, whilst inactive or whilst unacknowledged for continuous jobs (e.g. drive relay), or,
b.
on going active, on going inactive or on acknowledgement for 'one-shot' jobs (e.g. increment counter).
and associated text.
EVENT EXAMPLE
An event is to be active whenever Channel 1 Alarm 1 is active whilst Channel 3 alarm 2 is not active.
Source 1 = Point alarm (On = Channel 1; Alarm = 1)
Source 2 = Point alarm (On = Channel 3; Alarm = 2)
Source 1 Sense = Source 1
Operator = And
Source 2 Sense = Not Source 2
It is possible to achieve the same result by inverting both Source senses and using the Nor operator.
