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
for a descrip-
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).
Figure 4.3.3g, below, shows the various actions graphically. For 'While unacknowledged' and 'on acknowledgement'
settings, two cases are shown, one where the alarm goes inactive before acknowledgedment; the other where the
alarm is acknowledged whilst the alarm is still active. The coloured (shaded) areas show the duration for which con-
tinuous jobs run; the down arrows show trigger points for 'one-shot' jobs. See
for details on how to
acknowledge alarms.
