4 digital input channels 4 digital channels, configurable as inputs or outputs 1 universal counter pair (2 event counters, AB counters or up/down counters) Linear movement generator (A/B, direction/frequency) with up to 2 reference pulses SSI absolute encoder NetTime timestamp: Input data, target position, position change, edge change, counter change This module is a multifunction digital signal processor module. It can be used extremely flexibly for a wide variety of tasks involving digital signal processing or digital signal generation. Two primary example applications include controlling stepper output stages with pulse and direction signals or using as encoder emulation. In this application, for example, frequency inverters or servo axes with the speed follow function can follow a real or virtual master axis. An additional essential feature is the module's integrated timestamp function. It allows counter ramps curves to be generated virtually independently of bus cycle times during encoder emulation, for example. Only the target counter value and moment when it should be reached are transferred. The module automatically generates the corresponding counter values at the appropriate time, precisely in microsecond resolution and independently of the bus clock.
