The control signal is used as a pulse train by on- and off switching impulse which was digital expensed.ДЄ special valve drive function is integrated in the mode DQ. The control of the digital channel is done by a pulse / pause duty cycle, which is cyclically depending on the output value and from which the user program can be updated. The putting signal is issued in the form of an impulse result of one and out switching impulses digitally. The digital channel is steered for with a pulse-/ break pulse duty ratio of 0.0% to 100.0%. The four outputs provide a pulse-width modulated output signal in this mode. Pulse width modulation for DQ 4x24VDC/2A HS.Дigital outputs with AC voltage up to 230V and relay outputs, NO as well as CO - complete the portfolio. There are modules with basic (BA) or standard functionality (ST) as well as enhanced functions (HF High Feature / HS High Speed). The distributed I/O system ET 200SP offers a comprehensive portfolio of digital outputs. For example the ET 200SP High-Speed-analog module AQ 2xU/I HS analog value can be issued more finely. The function Oversampling is also realized for output data. Typical applications are usually measurements for the detection of quality data and the collection of accurate position data, from which we can derive precise timing control function later. A major advantage of Oversampling is that no faster CPU-Cycle is required for recording the high temporal resolution measurements. Oversampling is always useful to use when measurements in a high temporal resolution should be available, but the application does not require a fast reaction to the single readings. The readings are available for further evaluation. All n readings collected and transferred then in chronological order for PROFINET-Controller. Oversampling provides the user with the possibility to determine of two till n readings in synchronous and in constant equal intervals within a PROFINET-Transmit clocking. Oversampling вЂ“ fast equidistant data acquisition or rather issue at moderate CPU-Cycles. Every controller can grasp it reading on the same channels.

Input data are provided up to 4 IO controllers. MSI - Module internalВ Shared Input for DI 8x24VDC HF.Extensive parameterization options permit adaptation to the application (upper and lower counter limit, choice flanks, these are counted, 2 reference values to set a status bit, input delay). The most common modules are also available in packs of ten, which avoids packaging material and speeds up unpacking.Д¤ channels for the connection of electronic pulse generators are available in the mode counting with a counting breadth of 32 bits and a maximum frequency of 10 kHz. Дigital Inputs for NAMUR sensors and modules for AC voltage ofВ 120 - 230 V complete the portfolio. The distributed I/O system ET 200SP offers a comprehensive portfolio of digital inputs.
