Examples – Counter Event
The following schedule will run on every 100
th
pulse received on high speed counter input
1C
:
RA1HSC(100)
In this case counter
1HSC
will count from 0 to 99 then reset to 0, at which time the schedule will trigger. This means that
if you read the value of
1HSC
within this schedule then it will generally always read 0.
The following schedule will be triggered on every second pulse received on digital input
1D
:
RA1C(2)
Examples – Serial Channel Event
The following schedule will run if the specific character sequence Pasta8zZ is received on the serial sensor port:
RB1SERIAL"Pasta8zZ"
The following schedule will run each time any string is received on the host port (assuming the port has been configured
for serial channel operation):
RG2SERIAL""
Trigger on Internal Event
Figure 10: Internal event (CV change) schedule
Report schedules can also be triggered by channel variables (CVs) changing value:
Trigger
Action
n
CV
Trigger if channel variable
n
CV
changes from zero to non-zero, or vice versa
n
+CV
Trigger if channel variable
n
CV
changes from zero to non-zero
n
–CV
Trigger if channel variable
n
CV
changes from non-zero to zero
m
..
n
CV
Trigger if any of the channel variables
m
..
n
CV
change from zero to non-zero, or vice versa
m

+CV
Trigger if any of the channel variables
m

Examples
The schedule header
RK6CV
instructs the DT80 to run schedule K upon any change of channel variable 6CV to or from zero.
The schedule header
RA11..13+CV
instructs the DT80 to run schedule A whenever either 11CV, 12CV or 13CV change from 0 to any other value.
Trigger on Poll Command
Figure 11: Polled schedule
Instead of a time or event trigger, the poll trigger (X) can be applied to a report schedule. The schedule will then only run
when it is polled.
The command to poll a schedule is Xs (where s is the schedule letter). This command can be issued:
•
by a host computer, or
•
by an alarm action (see
Using an Alarm to Poll a Schedule (P90)
).
