* If the above error messages are displayed on the X1 series unit without establishing communication between X1 and PLC, test the solution "1". If the error
occurs suddenly during communication, test the solution "2".

Contents
Although a request to send is given to a controller, no
answer is returned within the specified time.
An error occurred in parity check.
Although the stop bit must be "1", it was detected as "0".
After receiving one character, the next character was
received before internal processing was completed.
The check code in the controller response was not correct.
An error code was sent by a controller.
(NAK)
The controller's SD remains at the low level.
An address outside the permissible range of the connected
PLC was specified.
The code of the received data was different from the
specified code.
Transmitted data and received data were inconsistent.
The X1 series unit judged that communication is
impossible.
Transmitted transaction data and received transaction data
were inconsistent.
The expected data amount was different from the count
value.
The response code was different from the expected code.
There is no memory cassette that corresponds to the
cassettes currently supported.
Unsupported CPU type (incorrect password)
Unsupported CPU type
The corresponding DB cannot be found in the CPU.
Solution
1. Check the settings in the [Hardware Setting]  [PLC
Properties] window.
Check that the cable is correctly connected.
2. Data may be disrupted because of noise.
Take measures against noise.

Examine the controller error code and solve the problem.
Examine the connection between the controller's SD and the
X1's RD.
Check the type and range of the specified device memory.
1. Confirm link unit settings.
(After making settings, turn off the power to each
controller.)
On the V-SFT version 6 editor, select [System Setting] 
[Hardware Setting], and check the settings.
2. If errors only occur from time to time, data may be
disrupted because of noise.
Take measures against noise.
Contact your local distributor.
Check whether or not the X1 series unit supports this CPU.
Check if the corresponding DB exists using the ladder tool.
If the DB does not exist, create it using the ladder tool.
