CHECK/CLEAR ERROR CODES
23.1
Checking Error Codes
Error codes can be checked by any of the following methods:
• Checking with the FPGA Module Configuration Tool ( Page 121 Module diagnostics)
• Checking by using CC-Link IE TSN/CC-Link IE Field diagnostics (in CC-Link IE TSN communication mode) ( Page 450
Checking by using CC-Link IE TSN/CC-Link IE Field diagnostics)
• Checking by Latest error code (RWr0) ( Page 117 Batch monitor display)
Checking by using CC-Link IE TSN/CC-Link IE Field diagnostics
In CC-Link IE TSN communication mode, the error history stored inside the FPGA module can be read. Errors that occurred
before powering-off can be checked as well.
• The error history records a maximum of 16 errors in reverse chronological order of occurrence. If more than
16 errors occur, errors are deleted from the oldest.
• If the same error occurs continuously, only the error that occurred first is stored to the error history.
• The error history is stored in the non-volatile memory in the FPGA module. 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
error history cannot be stored in the non-volatile memory.
• "Occurrence Date" information in the error history is recorded after clock information is distributed from the
master station. When an error occurs before clock information is distributed from the master station,
"Occurrence Date" information is not recorded. If the date and time of occurrence are not recorded, the
engineering tool displays "----/--/-- -:--:-- ---".
