The call to the respective time-delay interrupt OB will not beissued.The following conditions must be satisfied before a time-delay interrupt OB may becalled:n The time-delay interrupt OB must have been started(using the SFC 32).n The time-delay interrupt OB must not have been de-selected.n The time-delay interrupt OB must exist in the CPU.ParametersParameter Declaration Data type Memory block DescriptionOB_NR INPUT INT I, Q, M, D, L,constantNumber of the OB, that must be cancelled(OB 20, OB 21).RET_VAL OUTPUT INT I, Q, M, D, L The return value contains an error code if an erroris detected when the function is being processed.RET_VAL (Return value)Value Description0000h No error has occurred.8090h OB_NR parameter error80A0h Time-delay interrupt has not been started.14.1.25 SFC 34 - QRY_DINT - Query time-delay interruptThe SFC 34 QRY_DINT (query time-delay interrupt) can be used to make the status ofthe specified time-delay interrupt available via the output parameter STATUS.AccuracyDescriptionConditionsDescriptionVIPA SPEED7 Integrated StandardSystem Functions > SFC 34 - QRY_DINT - Query time-delay interruptHB00 | OPL_SP7 | Operation list | en | 18-30 675
