103B StartupInterval¶

Stub MON 103B (67 decimal) · Mnemonic INTV · Group: RT Program Execution (manual section 2.10)

Available from: RT programs (manual compatibility box)

Emulation source: src/handlers/mon_103B_StartupInterval.c

Description¶

Prepares an RT program for periodic execution. The interval between the executions can be specified in hours, minutes, seconds, and basic time units. A basic time unit is 1/50th of a second.

Notes¶

The RT program is not started. Use StartRTProgram, @RT, or similar, to start it.
StopRTProgram, Disconnect, @ABORT or @DSCNT cancel this monitor call.
One execution may be unfinished when it is time for the next execution, in which case the program's restart flag is set. If the delay becomes as long as two intervals, one execution is lost.
The interval replaces any earlier specified intervals.
AdjustClock and @CLADJ do not affect the interval.

Parameters¶

Name	Type	Direction	Description
`RTProgram`	INTEGER	In	Address of RT description. 0 means calling program. GetRtAddress gives RT description addresses.
`Time`	INTEGER	In	Number of time units between executions of the program.
`Units`	INTEGER	In	Type of time units: 1 = basic time units (1/50th second) 2 = seconds 3 = minutes 4 = hours

Direction: In = the program supplies the value, Out = the call returns it, In/Out = both.
