The output parameter STATUS contains information. It is interpreted as ARRAY[1...4] OF
BYTE the error information has the following structure:
Field element Name Description
STATUS[1] Function_Num 00h: if no error
Function ID from DP-V1-CPU:
in error case 80h is OR linked.
If no DP-V1 protocol element is used: C0h
STATUS[2] Error_Decode Location of the error ID
STATUS[3] Error_1 Error ID
STATUS[4] Error_2 Manufacturer specific error ID expansion:
With DP-V1 errors, the DP master passes on STATUS[4] to the CPU and
to the SFB.
Without DP-V1 error, this value is set to 0, with the following exceptions
for the SFB 52:
n STATUS[4] contains the target area length from RECORD, if MLEN >
the target area length from RECORD
n STATUS[4]=MLEN, if the actual record set length < MLEN < the target
area length from RECORD.
STATUS[2] (Location of the error ID) can have the following values:
Error_Decode Source Description
00 ... 7Fh CPU No error no warning
80h DP-V1 Error according to IEC 61158-6
81h ... 8Fh CPU 8xh shows an error in the nth call parameter of the SFB.
FEh, FFh DP Profile Profile-specific error
STATUS[3] (Error ID) can have the following values:
Error_Decode Error_Code_1 Explanation according to
DP-V1
