6.2.2-2) Error code table

Error code Contents of error

Cause of an error

01H

Function code defective In case of receiving the no prescribed function code.

02H

Relative No. (Reference
No) defective

In case of receiving the no prescribed start No or setting
value No.

03H

The data number
defective

In case the number of the transmitting data that answers
to the received message is exceeding the number that
prescribed.

11H

Out of the setting value
range

In case of programming the numerical value other than
setting range that was prescribed in the reference table.

12H

Programming impossible In case of programming it, when it is not locked.
