4.3.3 CHANNEL/ALARM CONFIGURATION (Cont.)
JOB NUMBER
Select the required job number.
CATEGORY
Select the required job to be carried out when the channel is in alarm (e.g. Drive relay) See section 4.7
for a description of job categories.
WHILE/ON
Allows the action of the alarm job to be chosen as
a. while active, while inactive or while 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 coun-
ter).
Figure 4.3.3g, below, shows the various actions graphically. For ‘While unacknowledged’ and ‘on ac-
knowledgement’ settings, two cases are shown, one where the alarm goes inactive before acknowledge-
ment; the other where the alarm is acknowledged whilst the alarm is still active. The coloured (shaded)
areas show the duration for which continuous jobs run; the down arrows show trigger points for ‘one-
shot’ jobs. See
section 3.1.4
for details on how to acknowledge alarms.
