The following conditions must be satisfied before a time-delay interrupt OB may be
called:
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.
Parameters
Parameter Declaration Data type Memory block Description
OB_NR INPUT INT I, Q, M, D, L,
constant
Number 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
error is detected when the function is being pro-
cessed.
STATUS OUTPUT WORD I, Q, M, D, L Status of the time-delay interrupt.
RET_VAL (Return value)
Value Description
0000h No error has occurred.
8090h OB_NR parameter error
STATUS
Bit Value Description
0 0 The operating system has enabled the time-delay interrupt.
1 0 New time-delay interrupts are not discarded.
2 0 Time-delay interrupt has not been activated and has not expired.
3 - -
4 0 Time-delay interrupt-OB has not been loaded.
5 0 An active test function disables execution of the time-delay interrupt-OB.
14.1.26 SFC 36 - MSK_FLT - Mask synchronous errors
The SFC 36 MSK_FLT (mask synchronous faults) is used to control the reaction of the
CPU to synchronous faults by masking the respective synchronous faults.
The call to the SFC 36 masks the synchronous faults of the current priority class. If you
set individual bits of the synchronous fault mask in the input parameters to "1" other bits
that have previously been set will remain at "1". This result in new synchronous fault
masks that can be retrieved via the output parameters. Masked synchronous faults are
entered into an error register and do not issue a call to an OB. The error register is read
by means of the SFC 38 READ_ERR.
