1 Overview of Errors
Unit
CJ-series Basic I/O Unit
CJ-series Special Unit
Devices connected with EtherNet/IP • For the originators of tag data
*1 Excluding Servo Drives assigned to an axis.
*2 Settings and setting methods depend on the slave. Refer to the manual for the slave. For a Servo Drive, opera-
tion depends on the setting of object 605E hex (Fault Reaction Option Code).
*3 You can set whether to clear output or maintain the data from before the error occurred. Refer to the NJ-series
CPU Unit Built-in EtherNet/IP Port User's Manual (Cat. No. W506) for details.
The following table gives the operation of the CPU Unit and the I/O devices for the errors that are not
listed above.

 Event Code
Events that occur in a Controller have an event code. When an event occurs, the Sysmac Studio or
PT will display the event code. You can use the instructions that get error status to read the error
codes of current errors from the user program.
The event codes are 8-digit hexadecimal values. The first digit of a Controller event represents its
category. These categories are listed in the table below.
