J Maintenance and Debugging Functions
Requirements
Creating a user-defined error for specific
conditions (e.g., errors or specific signals
from the controlled system) but allowing
the CPU to continue running.
Creating a user-defined error for specific
conditions (e.g., errors or specific signals
from the controlled system) and stopping
the CPU as a result.
Determining if a specific output turns ON
within a specified time after an input turns
ON. If the output does not turn ON, an
error will be generated. Then the address
in the program responsible for the output
failing to turn on will be determined.
Creating a history of user-defined and
system errors that have occurred.
Creating an external output when a
non-fatal error occurs.
Turning OFF all outputs from Output
Modules for specific conditions.
Turning OFF all outputs from Output
Modules during trial system operation.
Maintaining I/O memory status when
starting operation.
Correcting the program during operation
(online editing).
