Marked Exit
The marked exit error looks like this in the error list:
Marked exit, destination cannot be 0, init, or error step
This error occurs when you designate a marked exit for a step with a
destination of 0, init, or an error step.
To correct the error, you must change the destination step of the marked
exit to a non-error step.
Warning Timeouts
The warning timeouts error looks like this in the error list:
Warning timeouts require at least one non-error input
transition destination
This error occurs, if you designate the destination of a step timeout as
WARNING, and all of the transitions in that step go to error steps, step 0,
or INIT.
To correct the error, you must provide a non-error destination for at least
one of the inputs in the step configuration.
DDMC32 offers various utilities for showing sequence and timing of
inputs and outputs. These are:
I/O Monitor
Step History
Input History
Extended Status
Using I/O Monitor
The I/O Monitor screen shows all inputs and outputs in the SDS instruction
and inputs in the DFA instruction, and the current status of each. With the
I/O Monitor screen, you can determine if inputs and outputs are actuating
properly.
For example, if the I/O monitor screen says the forward motor is on, but
on the machine the motor is not activated, check for a problem with your
motor. Likewise, if the motor is supposed to go on and the output shows
that the motor is off, check your software for a problem.
