Time-based IO modules read in switching edges at digital inputs with a high time resolution, and supply time information, as well as the status, to the CPU.

For the digital outputs, switching commands with additional time information are transferred from the CPU. The outputs switch at a pre-defined time.

The modules can be used for diverse applications requiring accuracy below the resolution of the PLC or bus cycle. This requires no more than storage of the relevant instructions in the controller.

The following time-based I/O modules are available:

• Timer DIDQ 16x24V
  Time-controlled timer module with 8 inputs and 16 outputs, of which up to 16 with time stamp function; counter function up to 50 kHz, oversampling, pulse width modulation;
  requires isochronous mode
