5.3.1 Displaying the PLC Device Data

The various status signals and register data used in the PLC can be monitored and displayed.
When this screen is first selected, the respective 16-byte amounts of input/output data are displayed from
device "X0000" on the left display area, and from device "Y0000" on the right side.
This screen constantly monitors and displays the PLC signal statuses. Consequently, when signals are
changed in the PLC, the display is changed according to the changes.
Note that because time differences occur between the PLC signal change and the signal display, there may
be a delay in the display. The machine may also not be able to correspond to extremely brief signal changes.
