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

does not match the receive data.

Check the transmission data

Conversion Error

•When data type is

Device

and

Conversion Type

ASCII (HEX) to Binary

, a code other than

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.

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.

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

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

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.

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.
