3-11 Error Logging Function
The error log data of the RFID System can be read on-line through the Program-
ming Console.
Two types of error log data can be read, which makes it possible to analyze sys-
tem errors.
The Controller keeps a record of errors resulted in RUN mode after the Control-
ler is turned ON. The Programming Console can read information on these er-
rors, thus making it possible to find causes of errors. The Controller keeps a re-
cord of a maximum of 30 errors. New errors replace the existing record in chro-
nological order beginning with the oldest error record. The records will be com-
pletely lost when the Controller is turned OFF or reset or when it receives a RE-
SET command.
The Controller keeps a count of the number of times that each type of error (error
code) has occurred. The Controller also calculates MCBF (mean cycle between
failures) simultaneously. The Controller keeps all these data items until the user
turns OFF or resets the Controller.
The following formula is used to calculate the MCBF:
MCBF
+
Total number of host commands
Total number of errors that occurred
To use this function, connect the C200H-PRO27-E Programming Console (sold
separately) to the Controller through the V700-P10 Programming Console Con-
version Cable (sold separately). Refer to 6-6-9 Latest Error Data and 6-6-10 Sta-
tistic Error Data for details.
Note The record of all errors will be lost when the Controller is turned OFF or reset or
when it receives a RESET command. Do not turn OFF or reset the Controller in
order to keep the records.
