S5-100U
Introduction to STEP 5
7.4.1
Program Processing with CPU 102
You can process the program in the following two modes:
•
Normal mode
•
Test mode
Program processing is faster in the normal mode, but you can not use the STATUS test function.
Transferring from one mode to the other is called a mode change.
Test Mode:
Scanning the STEP 5 program
Normal Mode:
The control program you have written in STEP 5 is not processed directly. What is processed is a
translated or runtime-optimized form of the program generated by the programmable controller.
