4.9.1 EMBEDDED SEQUENCES (Cont.)
EXAMPLES
An alarm going active on channel 3 has 'Print Message 1 on going active' as one of its jobs.
If Message 1 were set up to be:
<TIME><.TA><-PV>
then the current time and the tag and process value of chan-
nel 3 would be printed on the chart.
If, instead, Message 1 were
<TIME><6.TA><6-PV>
then the current time and the tag and process value of chan-
nel 6 would be printed on the chart when the channel 3 alarm went active.
4.10 INTERNAL EVENTS
As standard, there are six internal events, which can be triggered by one or more sources, and which can generate up
to two jobs each when active. Input sources can be ANDed or ORed, so multiple logical inputs can be used.
For example, to send a log to the chart when any alarm on channel 1 and channel 2 and channel 4 are active, we
could set up events 1 and 2 as follows:
Event 1:
Event 2:
Job 1:
Enabled

Log 1 to chart
Source 1(S1) AND Source 2 (S2)
S1 AND S2

S1:Alm on channel 1.

S2:Alm on channel 2.
