Parameter Declaration Data Type Memory Area Description
SD_i,
1
≤ i ≤ 10
IN_OUT ANY I, Q, M, D, T, C i-th associated value
Only the following data types are
permissible: BOOL (not allowed: bit field),
BYTE, CHAR, WORD, INT, DWORD,
DINT, REAL, DATE, TOD, TIME, S5TIME,
DATE_AND_TIME.
Note:
If the ANY pointer accesses an DB, the
DB must always be specified (for
example: P# DB10.DBX5.0 Byte 10).
Error Information
The following table contains all the error information specific to SFB 36 that can be
output with the ERROR and STATUS parameters.
ERROR STATUS
(Decimal)
Explanation
0 11 Message lost, signal transition/message could not be sent
0 22 • Error in the pointer to the associated values SD_i:
- involving the data length or the data type
- associated values in the user memory not accessible,
for example, due to
deleted DB or area length error
The activated message is sent without or eventually with the possible
number of associated values
• The actual parameter you have selected for SEVERITY is higher than the
permitted range. The activated message will be sent with SEVERITY=127.
0 25 Communication was initiated. The message is being processed.
1 1 Communications problems: connection aborted or no logon
1 4 At the first call:
• The specified EV_ID is outside the permitted range or
• The ANY pointer SD_i has a formal error
• The maximum memory area that can be sent for the CPU per SFB 36 was
exceeded
1 10 Access to local user memory not possible (for example, access to a deleted DB)
1 12 When the SFB was called:
• an instance DB that does not belong to SFB 36 was specified
• a shared DB instead of an instance DB was specified
1 18 EV_ID was already being used by one of the SFBs 31 or 33 to 36.
1 20 Not enough working memory.
H-System: SFB called while update in progress
1 21 The message with the specified EV_ID is disabled
