Description:
  • 3 digital 5 V channels, configurable as inputs or outputs
  • 2 digital 24 V input channels
  • 1 universal counter pair (2 event counters, AB counter or up/down counter)
  • Linear movement generator (A/B; direction/frequency) with one reference pulse
  • SSI absolute encoder
  • NetTime timestamp: Input data, target position, position change, edge change, counter change

The module being used is a multifunctional digital signal processor module. It's flexibility allows it to be implemented for a wide range of tasks involving the creation or processing of digital signals. For example, two main uses include encoder emulation and controlling stepper output stages with pulse and direction signals. When used for encoder emulation, frequency inverters or servo axes with the speed follow function can follow a real or virtual master axis.

A further important feature is the timestamp function, which is integrated in the module. It can be used, for example, to create ramp curves for the counter in the encoder emulation virtually independent of bus cycle times. It's only necessary to enter the target counter value and the time at which it should be reached. The module generates the appropriate counter values, precisely in microsecond resolution and independently of the bus clock.
