Digital Input Modules SM 521

The modules have high channel density and low parts variance. As a result, ordering, logistics and spare-parts inventory are considerably simplified.

High Feature modules with enhanced functionality are only available with the 35mm form factor. Modules with a width a width of 35 mm can be equipped with a front connector using screw terminal or push-in technology, the connector has to be ordered separately.
The narrow 25mm modules use a front connector with push-in technology which is included in the scope of delivery. The modules have the same mechanical structure as the 35 mm modules. They also offer the same operability and the same accessories. Moreover, the pin assignment in the wiring is unchanged. This means that circuit and wiring diagrams can be universally used.

The narrow, low-cost modules do not have any parameter assignment or diagnostics, so integration in the engineering is significantly easier.
The narrow 25 mm modules can be mixed with the 35 mm modules as required.

Analog input modules SM 531

Analog input modules record process signals such as pressure or temperature and forward them in digitalized format (16 bit format) to the control. They are suitable for measuring current (2-wire and 4-wire transducers), voltage, and resistance, as well as for the connection of resistance thermometers and thermocouples (measurement types depend on the module).

Modules with a width of 35 mm can be equipped with a front connector using screw terminal or push-in technology, the connector has to be ordered separately.
The narrow 25mm modules use a front connector with push-in technology which is included in the scope of delivery. The modules have the same mechanical structure as the 35 mm modules. They also offer the same operability and the same accessories. Moreover, the pin assignment in the wiring is unchanged. This means that circuit and wiring diagrams can be universally used. For all analog input modules the components for shielding like power supply element, shield bracket, and shield terminal are included in the scope of delivery

The narrow 25 mm modules can be mixed with the 35 mm modules as required.

 

Expanded functions for analog inputs

Oversampling (for SM 531 AI 8XU/I HS)

The use of the oversampling function requires an isochronous configuration.
For analog input modules, the preset transmit clock is divided into up to 16 time-equidistant subcycles. The module reads in a measured value in each subcycle and saves it. The read in measured values of a data cycle are copied to the interface module (IM) of the ET 200MP in the next transmit clock and are available to the processing CPU one transmit clock later.
A major advantage of Oversampling is that no faster CPU-Cycle is required for recording the high temporal resolution measurements.

Scaling of the measured values (for SM 531 AI 8XU/I HF)

With scaling of the measured values, the value corresponding to the technological quantity of the process can be assigned to the physical measured values of the module (current or voltage). This saves time and memory during program processing in the CPU, as the analog input module converts the physical value directly and makes it available to the user program as 32-bit floating point value (REAL).

Measuring range adjustment (for SM 531 AI 8XU/R/RTD/DC HF)

The measuring range adjustment to the used sensor enables you to increase the resolution for a configurable section of the measuring range in S7 format. Sensors frequently do not use the entire nominal range of a module but only return voltage values in a partial range. By configuring the sensor limits in the TIA Portal, the original measuring range is expanded. The resolution of the measured values is more detailed.

Calibration at RUN (for SM 531 AI 8XU/I HF and SM 531 AI 8 XU/R/RTD/TC HF)

Repeated calibration may be particularly useful for plants in which sensors measure or process relatively small voltages or currents. Recalibration compensates for any effects on the measurement result caused by cables, temperature or sensor and can be executed in RUN of the CPU. Thereby, the latest values are acquired and saved retentively on the module.

Scalable temperature measurement range (for SM 531 AI 8 XU/R/RTD/TC HF)

To keep the process temperature at a constant operating point, the module must provide a relatively high resolution. Therefore, the operating point of the process gets defined as "measuring range mean". By limiting the measuring range to a smaller area, the 16-bit resolution of the module can be applied to this range which permits a significantly higher resolution of the measurement and therefore accurate calculations.

The narrow 25 mm modules can be used side by side with 35 mm modules in one station.

Expanded functions for analog outputs

Oversampling (for SM 532 AQ 8XU/I HS)

The use of the oversampling function requires an isochronous configuration.
For analog output modules, the preset transmit clock is divided into up to 16 time-equidistant subcycles. A data packet is transferred by the controller to the module and written to the process divided into n equidistant subcycles. The read or output values are transferred in the user data of the analog module. This increases the address space of the module.
A major advantage of Oversampling is that no faster CPU-Cycle is required for recording the high temporal resolution measurements.

Isochronous mode (for SM 532 AQ 4XU/I HF)

With the "Isochronous mode" system property, measured values and process data can be acquired with a fixed system clock. The signal processing until switching on the output terminal occurs in the same system clock. Isochronous mode thus contributes to high quality of the controller and therefore to greater manufacturing precision. Possible fluctuations of the process response times are significantly reduced. Time-assured processing, i.e. the high deterministic response, can be used for a higher machine cycle.
