Digital I/O Area (14):
This area consists of three entry fields below the Real-Time Monitor area. The entries determine the
configuration and settings of the eight DIO pins (D0 to D7).

Function
The hexadecimal number entered here defines the pattern that is applied
to the I/O pins.
The hexadecimal pattern entered in this field determines whether a
DEDGE interrupt is generated upon a bit changing its status. A 1 means
that the corresponding DIO pin generates an interrupt.
DEDGE interrupts are only generated for DIO pins that are configured
as inputs.
The hexadecimal number entered here defines whether I/O pins are inputs
(0) or outputs (1).
A signal transition on an input pin will generate a DEDGE interrupt only once. This interrupt will not be syn-
chronized with the accumulation interval or the 1-sec interrupt. Several transitions per accumulation interval
are possible.
With every signal transition on a DIO pin, the message “Some Dn pin values have changed!” will be
displayed in the Status Window.
Status Window Area (15):
This is the white, rectangular window at the bottom center of the GUI display. Activities of the PMtest.exe
GUI Control program, error messages etc. are listed here.
If more events occur than can be displayed in the lines of this window, the display will scroll. Events and
messages that occurred in the past will then be displayed by scrolling the window using the scroll arrows to
the right of it.
When the rectangular CLEAR button above the Status Window is pressed, the messages displayed in the
Status Window are deleted.
