STATUS Event text
(Hex)
A00E The length indicated in the MODBUS specific telegram
header does not match the number of registers/bits or
the byte count in the telegram. The FB receives all data
and ignores them.
MODBUSCP V2.x:
All connections via Port 502 are terminated and
reestablished.
MODBUSCP V1.x:
As an after effect a loss of synchronization might occur.
A00F A protocol identifier <> 0 was received.
MODBUSCP V2.x:
All connections via Port 502 are terminated and
reestablished.
MODBUSCP V1.x:
As an after effect a loss of synchronization might occur.
A010 In the parameterized area db_1 to db_8 a DB number is
used twice.
A011 An invalid value for DATA_TYPE is given (Value range:
1 to 4).
A012 The parameterized areas data_type_1 and data_type_2
overlap.
A013 The parameterized areas data_type_1 and data_type_3
overlap.
A014 The parameterized areas data_type_1 and data_type_4
overlap.
A015 The parameterized areas data_type_1 and data_type_5
overlap.
A016 The parameterized areas data_type_1 and data_type_6
overlap.
A017 The parameterized areas data_type_1 and data_type_7
overlap.
A018 The parameterized areas data_type_1 and data_type_8
overlap.
A019 0 is assigned to one of the parameters db_x while the
according data_type_x is <> 0.
DB 0 can't be used; it is reserved for system functions.
A01A Wrong length in header:
Range of values: 3 to 253 bytes.
MODBUSCP V2.x:
All connections via Port 502 are terminated and
reestablished.
A01B CP is server and function code 5:
An invalid value for coils was received.
The CP sends an exception telegram.

Diagnostics
Remedy
Verify the data of the
communication partner with the
help of a telegram trace.
Correct the parameterization of
db_x.
Correct the parameters.
Correct the parameterization.
The data areas must not contain
any overlapping register areas.
Correct the parameterization of
db_x to > 0.
Verify the data of the
communication partner with the
help of a telegram trace.
