14.1.8 SFC 6 - RD_SINFO - Read start information
The SFC 6 RD_SINFO (read start information) retrieves the start information of the last
OB accessed and that has not yet been processed completely, as well as the last startup
OB. These start information items do not contain a time stamp. Two identical start infor-
mation items will be returned when the call is issued from OB 100.
Parameter Declaration Data type Memory block Description
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 processed.
TOP_SI OUTPUT STRUCT D, L Start information of the current OB
START_UP_SI OUTPUT STRUCT D, L Start information of the last OB that was
started
This refers to two identical structures as shown below.
Structure element Data type Description
EV_CLASS BYTE Bits 3 ... 0: event identifier
Bits 7 ... 4: event class
1: Start events of standard-OBs
2: Start events of synchronous-error OBs
3: Start events of asynchronous-error OBs
EV_NUM BYTE event number
PRIORITY BYTE Structure element PRORITY shows the priority class of the cur-
rent OB.
NUM BYTE Structure element NUM contains the number of the current OB or
of the last OB started
TYP2_3 BYTE Data identifier 2_3: identifies the information entered into ZI2_3
TYP1 BYTE Data identifier 1: identifies the information entered into ZI1
ZI1 WORD Additional information 1
ZI2_3 DWORD Additional information 2_3
The content of the structure elements shown in the table above corre-
sponds exactly with the temporary variables of an OB. It must be remem-
bered, however, that the name and the data type of the temporary varia-
bles in the different OBs might differ. Furthermore, the call interface of the
OBs also contains the date and time at which call to the OB was
requested.
