ret_val := QRY_CINT(
ob_nr:=_int_in_,
cycle=>_udint_out_,
phase=>_udint_out__,
status=>_word_out_);
Data type Description
OB_CYCLIC OB number (accepts symbolic name like OB_MyOBName)
Int Execution condition code
UDInt Time interval, in microseconds
UDInt Phase shift, in microseconds
Word Cyclic interrupt status code:
Bits 0 to 4, see the STATUS table below
•
Other bits, always 0
•
STATUS parameter
Value Description
0 During CPU RUN
1 During startup
0 The interrupt is enabled.
1 Interrupt is disabled via the DIS_IRT instruction.
0 The interrupt is not active or has elapsed.
1 The interrupt is active.
0 The OB identified by OB_NR does not exist.
1 The OB identified by OB_NR exists.
Always 0
Description
Invalid phase shift time
OB has no attached event
Description
Get parameter and execution status from a cyclic
interrupt OB. The values that are returned existed
at the time QRY_CINT was executed.
