14.3 MEWTOCOL Error Codes
14.3.1 Table of Error Code
The same error codes are used for the computer link function and data link function.
Link system error
Error
code
Error name
Steps to take
22H
WACK error
The receive buffer of the partner node has overflowed.
Steps to take:
Keep the data size within the maximum range.
23H
MEWTOCOL station
No. overlap
The transmission has been interrupted because the MEWTOCOL station number
of the source node duplicates that of another node.
Steps to take:
Change the setting for the MEWTOCOL station number and try again.
24H
ET-LAN unit
hardware error
Hardware error in communication control unit
Steps to take:
Turn the power supply off and then on again.
- If the error still occurs, replace the unit.
- If the error does not occur, the malfunction may have been caused by noise.
Check the installation and layout of the transmission line and the usage
environment.
26H
MEWTOCOL station
No. setting error
A value other than 01 to 64 has been specified for the MEWTOCOL station
number of the source node.
Steps to take:
Specify a MEWTOCOL station number within a range of 01 to 64.
27H
No support error
An attempt was made to send a packet that is not supported by the system.
Steps to take:
Please contact your dealer.
28H
No response error
Timeout error while waiting for response from partner station.
Steps to take:
Use the application program to send the transmission again.
30H
Time-out error
Ongoing transmission disabled status
Steps to take:
Use the application program to send the transmission again.
32H
Transmission
impossible error
The transmission was interrupted because the buffer of the source node
overflowed.
Steps to take:
Keep the data size within the maximum range.
33H
Communication stop
The transmission was interrupted because the network access switch of the
MEWNET-H link unit serving as a relay was off.
Steps to take:
Turn on the network access switch.
36H
No destination error
- No partner station exists on the network.
- Network access was disengaged.
Steps to take:
- Check to see if a partner station exists on the network.
- Use the application program to send the transmission again.
38H
Other
communication
errors
Transmission error other than the above
Steps to take:
Use the application program to send the transmission again.
Note1) When the error occurred on the second or a higher hierarchy level of a multiple-hierarchy link, no
response will be returned.
Note2) For basic procedure errors, processing errors, and programmable controller application errors, if
a link-related error (including hierarchical) occurred within the network, no response will be returned.
