You can monitor the operation of your program by viewing the program files
and the data files.
Monitoring the Program
You should now be running the program MICRO . You can test the operation
of your program by monitoring the relay instruction states. Instruction state
boxes appear to the right of each bit instruction. When filled, these boxes
indicate that logical continuity exists in the program.
1. From the home screen, access the program monitor.
MON ENT
R 0 0 1
O / 1 0
You return to the last location you were at within the program. The
instructions will either be on or off, depending on the input and output
states in your program.
2. Arrow back to bit I/6 on rung 0 of the program. As you do this, look at
the instruction state boxes and see which ones, if any, are filled.
7 times
R 0 0 0
I / 6 0
Currently, I/6 is off. If I/6 is turned on, the instruction state box will be
filled. This will result in a path of logical continuity in the rung, causing
the output instruction state box to be filled as well.
