Message Communications Error Indications
1,2,3...
There are two ways to obtain information on communications errors that occur
in message communications: checking the EtherNet/IP Unit’s error log or
checking its indicators.
1. Each time a communications error occurs, an error code is placed in an er-
2. When a communications error has occurred, details on the error are indi-
ror record in the error log stored in RAM in the EtherNet/IP Unit or CPU
Unit with the built-in EtherNet/IP Port. Up to 64 records can be stored in
the error log. The time and date that the error occurred are also recorded
together.
The error log can be read or cleared from the CPU Unit by sending an FINS
command to the EtherNet/IP Unit (Error Log Read/Clear). The contents of
the error log can also be monitored from the Configurator.
cated by the MS and NS indicators and the 7-segment display on the front
panel of the EtherNet/IP Unit or CPU Unit with the built-in EtherNet/IP port.
This information can be used for troubleshooting.
