Description:
  • 4 digital input channels
  • 4 digital channels, configurable as inputs or outputs
  • 4 edge detection units with timestamp function (each can be used to measure pulse duration or differential time, 4 history elements per unit)
  • 4x precise edge generation down to the µs (up to four edges per unit in each case)
  • 4x oversampling (input and output signal)
  • 24 VDC and GND for sensor/actuator supply

This module is a digital signal processor module that is used for detecting and evaluating input edges and for creating edges.

High-speed input edges such as registration marks are acquired and given a precise input stamp independently of the X2X Link cycle time of the system. In the other direction, the module sets outputs at precisely defined times. This is done with a resolution of up to 125 ns.

In oversampling mode, the module acquires very short input patters whose low or high phases are shorter than the X2X Link cycle time. Similarly, output patterns (e.g. drum sequencers) can also be output with extremely short high/low times. Oversampling can take place with a scan rate of up to 25 μs.

If necessary, up to 4 events per edge detection unit are stored in a buffer (history elements).

Other functions include pulse duration measuring and differential time measuring.
