Parameters 2.2 Parameter description Parameter description Smoothing The individual measured values are smoothed by digital filtering. The smoothing can be adjusted in four steps, in which the smoothing factor k multiplied with cycle time of the electronic module equals the time constant of the smoothing filter. The greater the smoothing, the greater the time constant of the filter.

Analog value representation Introduction Electronic modules with analog outputs With the electronic module with analog inputs, continuously variable signals, such as those occurring in temperature measurement and resistance measurement, can be acquired, evaluated, and converted to digital values for further processing. Analog value representation for measuring range with SIMATIC S7 Analog value representation With the same nominal range, the digitized analog value is the same for input and output...
Analog value representation 4.3 Measuring ranges Output value The following table shows the representation of the binary analog values and the corresponding decimal and hexadecimal representation of the units of the analog values. The table below shows the resolutions 11, 12, 13, and 15 bit + sign. Each analog value is entered left aligned in the ACCU.

Analog value representation 4.4 Effect on analog value representation Effect on analog value representation 4.4.1 Effect of the supply voltage and the operating state on analog input values The input values of the analog modules are dependent on the supply voltage for electronics/encoders and on the operating state of the PLC (CPU of the DP master).
Connecting Connecting measuring sensors Introduction You can connect different measuring encoders to the analog input module: ● Current transmitters as: – 2-wire transmitters – 4-wire transmitters In this chapter you will find out how to connect the measuring encoders and what to watch out for when doing so.
Page 22
Connecting 5.1 Connecting measuring sensors Connecting measuring encoders to analog inputs There can only be a limited potential difference U (common mode) between the measuring lines of the input channels. To ensure that the permitted value is not exceeded, you must take different steps depending on the whether the encoders are isolated or non-isolated.
Page 23
Connecting 5.1 Connecting measuring sensors Isolated measuring encoders The isolated measuring encoders are not connected to the local ground potential. These can be potential-free. Depending on local conditions or interference, potential differences U (static or dynamic) can occur between the measuring lines M- of the input channels and the reference point of the measuring circuit M The permitted value for U must not be exceeded, even in environments with strong EMC...

Connecting 5.1 Connecting measuring sensors Non-isolated measuring encoders The non-isolated measuring encoders are connected to the local ground potential. Depending on local conditions or interference, potential differences U (static or dynamic) can occur between the locally distributed measuring points. If the permitted value for U is exceeded, there must be equipotential bonding conductors between the measuring points.
Connecting 5.2 Wiring unused channels of the analog input modules Wiring unused channels of the analog input modules Rules Pay attention to the following instructions when wiring unused channels: ● "Deactivate" unused input channels when assigning parameters. ● A deactivated channel always returns the value 7FFF Using the shield connection Rules To prevent interference we recommend the following for analog electronic modules:...
