Appendix 7.11 Network Errors (L)
L12 DN LINK ERROR 28 (Error-detected slave node No. )
Details
A deviceNet initialization error has occurred. The error-detected node No. is other than FFH
and FEH.
- Unexpected invalid data was received when establishing a connection.
"Error-detected slave node No." shows the error-detected slave node No. in decimal.
Remedy
- Check the entire network and slave node statuses such as whether or not a terminal
resistor is disconnected.
L12 DN LINK ERROR 29 (Error-detected slave node No. )
Details
A deviceNet initialization error has occurred. The error-detected node No. is other than FFH
and FEH.
- Connection has already been established with that slave node.
"Error-detected slave node No." shows the error-detected slave node No. in decimal.
Remedy
- Wait a while, and reset the slave node if the connection cannot be established.
L12 DN LINK ERROR 2A (Error-detected slave node No. )
Details
A deviceNet initialization error has occurred. The error-detected node No. is other than FFH
and FEH.
- The data length of a polling response is different from the data length read from the slave
node when establishing a connection.
"Error-detected slave node No." shows the error-detected slave node No. in decimal.
Remedy
- Check the entire network and slave node statuses such as whether or not a terminal
resistor is disconnected.
L12 DN LINK ERROR 2B (Error-detected slave node No. )
Details
A deviceNet initialization error has occurred. The error-detected node No. is other than FFH
and FEH.
- The first division data was received twice in the division reception of a polling response.
"Error-detected slave node No." shows the error-detected slave node No. in decimal.
Remedy
- Check the entire network and slave node statuses such as whether or not a terminal
resistor is disconnected.
L12 DN LINK ERROR 2C (Error-detected slave node No. )
Details
A deviceNet initialization error has occurred. The error-detected node No. is other than FFH
and FEH.
- The received division data No. is different from the expected No. in the division reception
of a polling response.
"Error-detected slave node No." shows the error-detected slave node No. in decimal.
Remedy
- Check the entire network and slave node statuses such as whether or not a terminal
resistor is disconnected.
