+0
0 BCC error
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.
Change the Calculation
Start Position and
Calculation End Position
settings.
• When Calculation Type is Modbus ASCII (LCR), the
data size from Calculation Start Position to
Calculation End Position is odd bytes.
• The data contains data other than ASCII (30h to 39h,
41h to 46h) data.
Change the Calculation Start
Position and Calculation End
Position settings and the
transmission data from the
external device.

Received Data
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), Constant
(Hexadecimal), Registering Constant
(Character), Registering Constant
(Hexadecimal), BCC, or Skip is processed.
• 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.
2
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.
3
Registering
Constant Error No data matches the registered setting of the
Registering Constant data.
Check the transmission data
from the external device.
4
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 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.
5
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
change the number of
words.
6
Terminal Code of
Receive Data
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.
15
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.
