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.
Description
No error
OB does not exist or is of wrong type
Invalid cycle time
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.
