 Examples — While Condition
The schedule header
RA1E:2W
instructs the DT80 to run schedule
A on every transition of digital input 1 (1E) only while digital input 2 is high (:2W).
The schedule header
RD1S:4~W
instructs the DT80 to run schedule
D every second (1S) while digital input 4 is low (:4~W).
The schedule header
RK2H:9W
instructs the DT80 to run schedule
K every two hours (2H) while digital input 9 is high (:9W).
The schedule header
RC5M:12CV
instructs the DT80 to run schedule
C every 5 minutes (5M) while channel variable 12 is not zero (:12CV).
The schedule header
RF6..8E:5W
instructs the DT80 to run schedule
F on any transition of digital channels D6, D7 or D8 (6..8E) while digital input 5 is
high (
:5W).
Immediate Report Schedules
Figure 15: Immediate schedule
Instead of scanning according to time or event triggers, immediate schedules run immediately — and once only — when
they are received by the DT80.
An immediate schedule is simply a list of input channels, output channels, calculations and/or alarms with no schedule
header (that is, no schedule ID and no trigger). The DT80 executes the list (up to the next carriage return) immediately
and once only.
Note: Any data resulting from an immediate schedule is returned to the host computer, but is not logged.
 Example — Immediate Report Schedule
Sending
1TK 2R(3W) 3TT
causes the DT80 to immediately scan analog channels 1, 2 and 3 once only and return the data. Notice that this
schedule has no schedule ID and no trigger.

Re-Running an Immediate Schedule
The last-entered immediate schedule can be run again by sending the * (asterisk) command — that is, by sending a *
character. For example:
1..2TK
1TK 31.5 degC
2TK 22.0 degC
*
1TK 34.2 degC
2TK 21.9 degC
