14.1.60 SFC 106 - DEL_SI - Reading Dynamic System ResourcesWhen messages are generated with SFCs 107 ALARM_DQ and 108 ALARM_D, theoperating 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 108calls it may happen that corresponding system resources stay permanently occupied. Ifyou reload the FB with SFC 108 or SFC 108 calls, it may happen that the SFCs 107 and108 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. Setthe desired operating mode via the MODE parameter.MODE Which of the system resources occupied by SFC 107/SFC 108 aredeleted?1 All (call of SFC 106 with SI_ID: = 0)2 The system resource occupied by the call of SFC 107-/SFC 108 withEV_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 withCMP_ID:= cmp_id(call of the SFC 106 with SI_ID: =e v_id)ParametersParameter Declaration Data type Memory Area DescriptionMODE INPUT INT I, Q, M, D, L,constantJob identifierPermissible valuesn 1: delete all system resourcesn 2: delete the system resource that was occu-pied with EV_ID = ev_id when SFC 107-/SFC108 was calledn 3: delete the system resources that wereoccupied with CMP_ID = cmp_id when SFC107-/SFC 108 was calledSI_ID INPUT DWORD I, Q, M, D, L,constantID of the system resource(s) to be deletedPermissible valuesn 0, if MODE = 1n Message number ev_id, if MODE = 2n ID cmp_id for identification of the system sec-tion, if MODE = 3RET_VAL OUTPUT INT I, Q, M, D, L Error InformationOverviewDescriptionVIPA SPEED7Integrated StandardSystem Functions > SFC 106 - DEL_SI - Reading Dynamic System ResourcesHB00 | OPL_SP7 | Operation list | en | 18-30726
