Error Code
(B#16#..)
H8 24
Area length error while reading a parameter
H8 25
Area length error while writing a parameter
This error code indicates that parameter x is located in an area which is not allowed for
the system function.
H8 26
The parameter contains a time location number which is too large.
H8 27
The parameter contains a counter location number which is too large.
H8 28
Offset error while reading a parameter
H8 29
Offset error while writing a parameter
The reference to parameter x is an operand whose bit address is not 0.
H8 30
The parameter is located in the write-protected global DB.
H8 31
The parameter is located in the write-protected instance DB.
H8 32
The parameter contains a DB number which is too large.
H8 34
The parameter contains an FC number which is too large.
H8 35
The parameter contains an FB number which is too large.
H8 3A
The parameter contains the number of a DB which is not loaded.
H8 3C
The parameter contains the number of an FC which is not loaded.
H8 3E
The parameter contains the number of an FB which is not loaded.
H8 42
An access error occurred while the system was trying to read a parameter from the I/O
area of the inputs.
H8 43
An access error occurred while the system was trying to write a parameter to the I/O
area of the outputs.
H8 44
Error during the nth (n > 1) read attempt after occurrence of an error
H8 45
Error during the nth (n > 1) write attempt after occurrence of an error
H8 7F
Internal error in parameter x. Cannot be corrected by the user.
H8 90
Specified logical base address is invalid: No assignment in SDB1/SDB2x exists, or it is
not a base address.
H8 92
A type other than BYTE has been specified in an ANY reference.
H8 93
The area identifier contained in the configuration (SDB1, SDB2x) of the logical address
is not permitted for these SFCs. Permitted:
S
0 = S7-400
S
1 = S7-300
S
2, 7 = DP modules
H8 A0
Negative acknowledgment while reading from module. FC fetches acknowledgment
although no acknowledgment is ready.
A user who is not using the FC 56 would like to fetch DR 101 (or DR 102 to 104)
although no acknowledgment is available.
S
Perform an init_run for new synchronization between ASM and application.
H8 A1
Negative acknowledgment while writing to the module. FC sends command although
ASM is unable to receive a command.
H8 A2
DP protocol error in layer 2. Could be a hardware defect.
H8 A3
DP protocol error in Direct-Data-Link-Mapper or User-Interface/User. Could be a hard-
ware defect.
