Enhanced functions with diverse modules
Pulse width Modulation (DQ 4x24VDC/2A HS)
The four outputs provide a pulse-width modulated output signal in this mode. The digital channel is steered for with a pulse-/ break pulse duty ratio of 0.0% to 100.0%. The putting signal is issued in the form of an impulse result of one and out switching impulses digitally.
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 control signal is used as a pulse train by on- and off switching impulse which was digital expensed.
Counting (DI8x24VDC HS):
4 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. 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).
Valve actuation (DQ 4x24VDC/2A HS)
A special valve drive function is integrated in the mode DQ. One switches on "1" signal at version a this and the exit for a parameterizable hold time then changes into a pulse break version whose frequency and pulse duty ratio are adjustable. The putting signal is issued in the form of an impulse result of one and out switching impulses digitally
MSI/MSO (Modulinternes Shared Input / Output)
Input data are provided up to 4 IO controllers. Every controller can grasp it reading on the same channels (DI 8 x24VDC HF). MSO allows that a output module places the status of his initial data up to another 3 IO controllers next to disposal (DQ 8 x24VDC/0.5 A HF, DQ 4 x24VDC/2 A HF.)
Oversampling (DI8x24VDC HS, DQ 4x24VDC/2A HS, AI 2xU/I 2-/4-wire HS, AQ 2xU/I HS):
Oversampling – fast equidistant data acquisition or rather issue at moderate CPU-Cycles
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. All n readings collected and transferred then in chronological order for PROFINET-Controller. The readings are available for further evaluation.
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. A major advantage of Oversampling is that no faster CPU-Cycle is required for recording the high temporal resolution measurements. 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.
The Function Oversampling is also for output data realized. For example the ET 200SP High-Speed-analog module AQ 2xU/I HS analog value can be issued more finely.
The two High speed digital modules DI 8 x24VDC HS and DQ 4 x24VDC are/2 of A HS, completely new in the product line of the SIMATIC ET 200 SP which also supports the mode Oversampling besides another two modes.
