Parameter Declaration Data type Memory block Description
REQ INPUT BOOL I, Q, M, D, L,
constant
REQ = 1: start processing
SSL_ID INPUT WORD I, Q, M, D, L,
constant
SSL_ID of the partial list or the partial list
extract
INDEX INPUT WORD I, Q, M, D, L,
constant
Type or number of an object in a partial list
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
BUSY OUTPUT BOOL I, Q, M, D, L BUSY = 1: read operation has not been com-
pleted
SSL_HEADER OUTPUT STRUCT D, L WORD structure with 2 types:
LENGTHDR: length record setN_DR: number
of existing related records (for access to partial
list header information) or number of records
transmitted in DR.
DR OUTPUT ANY I, Q, M, D, L Target area for the SSL partial list or the extrac-
tion of the partial list that was read:
If you have only read the SSL partial list header
info of a SSL partial list, you may not evaluate
DR, but only SSL_HEADER.
Otherwise the product of LENGTHDR and
N_DR shows the number of bytes stored in DR.
The return value contains an error code if an error is detected when the function is being
processed.
Value Description
0000h no error
0081h The length of the result field is too low.
The function still returns as many records as possible.
The SSL header indicates the returned number of records.
7000h First call with REQ = 0: data transfer not active; BUSY = 0.
7001h First call with REQ = 1: data transfer initiated; BUSY = 1.
7002h Intermediate call (REQ irrelevant): data transfer active; BUSY = 1.
8081h The length of the result field is too low. There is not enough space for one record.
8082h SSL_ID is wrong or unknown to the CPU or the SFC.
8083h Bad or illegal INDEX.
8085h Information is not available for system-related reasons, e.g. because of a lack of resources.
8086h Record set may not be read due to a system error.
