I/O Status Display
There are no LEDs for displaying the status of the C7-635 I/O. You can configure a
screen to display the I/O status (see Figure 4-5).
The represented values must be read as a direct process image of the DI and an
internal process image of the DO of the digital C7-635 I/O, and displayed in the
BIN format.
Note that when the C7-CPU is in STOP mode, the real process status DO is 0.
However, the last process status set by the program is displayed.
