Checking Event Codes and Error Codes

Checking method

Error codes and event codes can be checked by any of the following methods:
Item
Error code
Event code
To check the NZ2GN-GFB error and event history from the CC-Link IE Field Network master station and local stations,
connect to the CC-Link IE Field Network master station or local station that is connected to the NZ2GN-GFB by accessing
another station (connection destination) using an engineering tool, and start CC-Link IE TSN/CC-Link IE Field diagnostics.
Checking by using CC-Link IE TSN/CC-Link IE Field diagnostics
The error and event history held in the NZ2GN-GFB can be read. Information generated before powering off can be checked
as well.
• The error and event history records a maximum of 512 items in reverse chronological order of occurrence. If
more than 512 errors and events occur, information is deleted from the oldest first.
• If the same error occurs continuously, only the first information is stored in the history.
• The error and event history is stored in the non-volatile memory in the NZ2GN-GFB. It is not lost when the
power is cut off. However, when the upper limit for the number of writes to the non-volatile memory is
reached, the history cannot be stored in the non-volatile memory.
• The "Occurrence Date" information in the error and event history is recorded after clock information is
distributed from the CC-Link IE TSN master station. When an error and event occurs before clock
information is distributed from the master station, "Occurrence Date" is not recorded.
• When the NZ2GN-GFB is used as the CC-Link IE Field Network master station, the time distributed from the
CC-Link IE TSN master station is recorded as the occurrence time in the error and event history of the CC-
Link IE Field Network device station. For operations before the time is distributed, refer to the user's manual
for the CC-Link IE TSN master station used.
■Procedure
1.
Connect the engineering tool to the CPU module on the CC-Link IE TSN master station.
2.
