CPU Overview
Maintenance and Management
Applications
Determining if a specific output turns ON within
a specified time after an input turns ON,
generating an error if the output does not turn
ON, and determining the address in the program
responsible for the output not turning ON.
Solutions
• Use the FPD instruction to perform time or logic diagnosis of a specified portion
of the program.
Time diagnosis
Program section
Creating a history of user-defined and system
errors that have occurred.
Creating an external output when a non-fatal
error occurs.
Logic diagnosis
• Use the error log to record up to 20 time-stamped error records.
• Use the Non-fatal Error Flag.
