Digital Input Functions Furthermore, the function of every Digital Input can be selected from one out of 17
available functions. Every function performs its unique action on the Counter to
which it is assigned. The action can be performed on the rising or on the falling
edge of the Digital Input signal. Depending on the requirements of your application
you must select the corresponding Function. By default no function is assigned to
the Digital Inputs and no action is performed on a rising or falling edge of the Dig-
ital Input signal (only the status of the Digital Input is reported in CIO).
Note Every Digital Input can be configured to generate an Interrupt to the CPU. For
details refer to 4-6-2
"Digital Inputs Generating Interrupts" .
