SSL_HEADER
The SSL_HEADER parameter is a structure defined as follows:
SSL_HEADER: STRUCT
LENTHDR: WORD
N_DR: WORD
END_STRUCT
LENTHDR is the length of a data record of the SSL list or the SSL partial list.
If you have only read out the header information of an SSL list, N_DR contains
the number of data records belonging to it.
Otherwise, N_DR contains the number of data records transferred to the
destination area.
Error Information
Error Code
(W#16#...)
Description
0000 No error.
0081 Result field too short. (Nevertheless as many data records as possible are supplied. The
SSL header indicates this number.)
7000 First call with REQ=0: No data transfer active; BUSY has the value 0.
7001 First call with REQ=1: Data transfer started; BUSY has the value 1.
7002 Interim call (REQ irrelevant): Data transfer already active; BUSY has the value 1.
8081 Result field too short (not enough space for one data record).
8082 SSL_ID is wrong or is unknown in the CPU or SFC.
8083 INDEX wrong or not permitted.
8085 Due to a problem in the system, information is not currently available (for example, due
to a lack of resources).
8086 The data record cannot be read due to a system error (bus, modules, operating system).
8087 Data record cannot be read because the module does not exist or does not acknowledge.
8088 Data record cannot be read because the actual module identifier is different from the
expected module identifier.
8089 Data record cannot be read because the module is not capable of diagnostics or the data
record is not supported.
80A2 DP protocol error (layer 2 error) (temporary error)
80A3 DP protocol error with user interface/user (temporary error)
80A4 Communication problem on communication bus (error occurs between the CPU and the
external DP interface module)
80C5 Distributed I/Os not available (temporary error).
80C6 Data record transfer stopped due to priority class abort (restart or background)
80D2 Data record cannot be read because the module is not capable of diagnostics.
