14.1.60 SFC 106 - DEL_SI - Reading Dynamic System Resources
When messages are generated with SFCs 107 ALARM_DQ and 108 ALARM_D, the
operating system occupies temporarily system memory space.
For example, if you do not delete a FB that exists in the CPU with SFC 107 or SFC 108
calls it may happen that corresponding system resources stay permanently occupied. If
you reload the FB with SFC 108 or SFC 108 calls, it may happen that the SFCs 107 and
108 are not processed properly anymore.
With SFC 106 DEL_SI you can delete currently used system resources.
SFC 106 DEL_SI has three possible operating modes explained in the table below. Set
the desired operating mode via the MODE parameter.
MODE Which of the system resources occupied by SFC 107/SFC 108 are
deleted?
1 All (call of SFC 106 with SI_ID: = 0)
2 The system resource occupied by the call of SFC 107-/SFC 108 with
EV_ID: = ev_id
(call of the SFC 106 with SI_ID: = ev_id)
3 The system resource occupied by the call of SFC 107-/SFC 108 with
CMP_ID:= cmp_id
(call of the SFC 106 with SI_ID: =e v_id)
