14-1-2 Errors Related to the EtherNet/IP Function Module
The event levels for errors that are related to built-in EtherNet/IP are given in the following table.
Event level of the error Operation
Major fault All NJ-series Controller control operations stop for errors in this event level. A
major fault level error never occurs for the EtherNet/IP Function Module.
Partial fault All control operations for one of the function modules in the NJ-series Controller
stop for errors in this event level. If a partial fault level error occurs in the Ether-
Net/IP Function Module, all functions of the EtherNet/IP Function Module, such
as axis operation, stop.
Minor fault Some of the control operations for one of the function modules in the NJ-series
Controller stop for errors in this event level. If a minor fault level error occurs for
the EtherNet/IP Function Module, EtherNet/IP communications are possible, but
control may be affected. User action is required.
Observation Errors in the observation level do not affect NJ-series Controller control opera-
tions. Observations are reported in order to prevent them from developing into
errors at the minor fault level or higher.
Information Events that are classified as information provide information that do not indicate
errors.
