Error Log
Section 11-9
11-9 Error Log
Up to twenty errors detected and notified on the MC Unit can be stored in the
system variable in the MC Unit as the error log.
The system variables (error log) will be cleared when the power is restored or
the Unit is restarted. To store the error log, use the IORD instruction to make
the CPU Unit read and store it.
The error log is composed of 2 words for the number of stored records, and
120 (6 words
×
20 error records) words.
11-9-1 Area Configuration
• Errors are recorded up to 20 starting from the oldest error stored as Error
log 1.
• From the 21
st
error on, the oldest error is deleted and the newest is over-
written. For example, the 21
st
error is stored in the Error log 1, the 22
nd
error is stored in the Error log 2, and so on.
• The newest error is stored in the Error log with the number indicated by
the remainder of dividing SW0011: Error log No. of actual records by 20.
