3-4 Digital Input Functions
Assigning multiple Digital
Inputs to single Counters The High-speed Counter Unit is equipped with four Digital Inputs allowing every
Counter to be controlled by a Digital Input. For applications that require a Counter
to be controlled by more than one Digital Input, multiple Digital Inputs (i) can be
assigned to a Counter (i
≤
4). Digital Inputs can only be assigned to single
Counters. Consequently, if all Digital Inputs are assigned to one Counter, they are
not available anymore for the other Counters.
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" .
