Cause
The BCC that calculated the receive data did not match
the BCC that is appended to the receive data.
• The Calculation Start Position and Calculation End
Position are not stored in 1 frame.
• The Calculation End Position is set before Calculation
Start Position.
• When Calculation Type is Modbus ASCII (LCR), the
data size from Calculation Start Position to
Calculation End Position is odd bytes.
• The ASCII data contains data other than ASCII (30h
to 39h, 41h to 46h) data.
The received data size of the data does not match that
of the specified receive command.
The Constant (Character) or Constant
(Hexadecimal) set up with the receive command
does not match the receive data.
No data matches the registered setting of the
Registering Constant data.
• When data type is Device Address and
Conversion Type is ASCII to Hexadecimal, a
code other than 0 to 9 or A to F receives as data.
• When data type is Device Address and
Conversion Type is ASCII to Decimal, a code
other than 0 to 9 receives as data. Or the converted
data exceeds 65535.
When data type is Device Address and the Use
Reference Device Address check box is selected, the
device address in which the value of the Reference
Device Address is stored as offset has exceeded the valid
range. Or the number of words setting of the device
address is beyond the range of device address for which
data is stored.
In the receive command whose trigger condition is
being satisfied, the start code matches while the
terminal code does not match.
During the reception process of multiple received
commands, the total number of words of the next
device address to be stored exceeds 800 words.
•The stored device addresses that Type is Device
Address.
•Index device address whose Type is Registering
Constant (Character) or Registering Constant
(Hexadecimal).
