The BCC that calculated the receive data did not
match the BCC that is appended to the receive data.
Check the transmission data
from the external device.
• The Calculation Start Position and Calculation
End Position are not stored in 1 frame.
• The Calculation End Position is set before
Calculation Start Position.

End Position is odd bytes.
• The data contains data other than ASCII (30h to

Size Error
• When data type is
Device
and the
Variable
check box is
selected, 1 frame of process is completed before one of
Constant (Character)

• When data type is Device and the Variable
check box is not selected, the receive data size
of the receive data does not match that of the
specified receive command.
Check the transmission data
from the external device.

Registering
Constant Data
Error
The Constant (Character) or Constant
(Hexadecimal) set up with the receive command
does not match the receive data.
Check the transmission data
from the external device.

Registering
Constant Error
No data matches the registered setting of the
Registering Constant data.
Check the transmission data
from the external device.

Device Data
Conversion Error
• When data type is Device and Conversion
Type is ASCII (HEX) to Binary, a code other
than 0 to 9 or A to F, a to f *1 receives as data.
• When data type is
Device
and
Conversion Type
is
ASCII (DEC) to Binary
, a code other than
0
to
9
receives as data. Or the converted data exceeds 65535.
Check the transmission data
from the external device.

Device Data
Reference
Device Error
When data type is
Device
and the
Use Reference
check
box is selected, the device address in which the value of the
Reference Device is stored as offset has exceeded the valid
range. Or the number of words setting of the device is
beyond the range of device address for which data is stored.
Change the value of the
Reference Device or the

Miscompare
Error
In the receive command whose trigger condition is
being satisfied, the start code matches while the
terminal code does not match.
Check the transmission data
from the external device.
7
Device Storing
Error
In the multiple Receive (RXD) Commands
processing, the number of the same-time stored
devices which is sum of the number of the stored
device of Device and the number of the index
device of Registering Constant (Character) or
Registering Constant (Hexadecimal), is over
800 words.
Change settings so that the total
number of devices used for storage
at one time does not exceed 800
words.
Change settings so that the trigger
conditions for several receive
commands are not satisfied, to
reduce the number of receive
commands that are processed.

Receiving Time
Out
1 frame of data is not received even when the
preset Receiving Time Out duration has passed
after the Trigger Condition is satisfied.
Check the transmission data
from the external device.

Receiving
Character Time
Out
While 1 frame of data is being received, even after the time out
period—the specified time interval between receiving data
(from when 1 frame of data has been received to when the
next frame of data starts to be received)—has elapsed, the next
frame of data does not start to be received.
Check the transmission data
from the external device.
Address Function Description
+1 Receive Data Size (bytes) Stores the size of receive data.
After the Receiving Character Time Out duration has elapsed, the receive data is analyzed. When the Error
Information bit changes to 1, data is not received, and the Receiving Completed Device does not change to 1.
