After you test all inputs and outputs and they are functioning
properly, we
recommend the following steps to safely and
successfully enter and test your specific application program. (For
extra assistance, see the Hand-Held Terminal User Manual or your
programming software user manual.)
1. Verify the offline program.
After the program has been entered in the offline edit file mode,
program verification may begin.
Remaining in the offline edit file mode you may use the cursor
keys and/or search function of your programming device to
inspect every instruction and rung for errors.
2. Check your written program, rung for rung, against the program
entered into the offline memory. The most common errors found
in program entry are:
• incorrect addressing of instructions
• omission of an instruction
• more than one output instruction programmed using the same
address
3. Transfer the program into the processor:
A. Place your programming device online.
B. Place the processor into Program mode.
C. Select the download function when using the Hand-Held
Terminal or the restore function when using your
programming software.
4. Verify the online program transfer:
A. Select monitor file function.
B. Cursor through the program to verify that you selected the
right program.
5. Conduct a single-scan program test:
A. Select the monitor file function and place cursor on first
rung.
B. Select the Test mode.
C. Select Single-Scan (SSN) test. In this test mode, the
processor executes a single operating cycle, which includes
reading the inputs, executing the ladder program, and
updating all data without energizing the output circuits.
However, the monitor file function will identify output status
as if they were enabled.
Timers are also incremented a minimum of 10 milliseconds
each single scan.
