SFCs and SFBs for Updating the Process Image and Processing Bit Fields
System Software for S7-300/400 System and Standard Functions - Volume 1/2
14-2 A5E00709327-01
The updating of the OB1 process image input table and the process image input
sections that you assigned to an interrupt OB is not influenced by SFC 26 calls.
Parameter Declaration Data Type Memory Area Description
PART INPUT BYTE I, Q, M, D, L,
constant
Number of the process image input section to
be updated. Maximum value range (depends
on the CPU): 0 to 15 (0 means OB1 process
image, n where 1 <
n < 15 means process
image section n)
RET_VAL OUTPUT INT I, Q, M, D, L Error information
FLADDR OUTPUT WORD I, Q, M, D, L Address of the first byte to cause an error
if an access error occurred.
Error Information
Error Code (W#16#...) Explanation
0000 No error occurred.
8090 Illegal value for the input parameter PART.
8091 The specified process image section was not defined or is not in the
permitted process image table area on the CPU.
8092 The process image section is updated by the system with an OB and
you have not configured repeated signaling of all I/O access errors.
The process image was not updated by SFC 26 "UPDAT_PI"
80A0 An access error was detected during the updating.
8xyy General error information, see Evaluating Errors with Output Parameter
RET_VAL
Note
If you use SFC 26 "UPDAT_PI" for process image partitions of DP standard slaves
for which you have defined a consistency area larger than 32 bytes, the error
codes from SFC 14 "DPRD_DAT" are also possible.
