For the cyclic access to the diagnostics data of the system SLIO module 050-1BA00 the
following example may be used in the OB 1:
AN M10.3 'If the reading terminated (BUSY=0) and
AN M10.1 'there is no job triggered (REQ=0) then
S M10.1 'start transfer of record (REQ:=1)
L W#16#4000 'Number of record set (0x4000)
T MW12
CALL SFB 52, DB52 'Call SFB 52 with Instance DB
REQ :=M10.1 'Trigger flag
ID :=DW#16#0018 'Smaller addr. of mixed module
INDEX :=MW12
MLEN :=14 'Length record set 0x4000
'with 1 entry
VALID :=M10.2 'Validity of the record set
BUSY :=M10.3 'Flag job just running
ERROR :=M10.4 'Error bit during read access
STATUS :=MD14 'Error codes
LEN :=MW16 'Length of the read record set
RECORD :=P#M 100.0 Byte 40
'Target (MB100, 40byte)
U M10.1
R M10.1 'Reset REQ
