Device Stack supports Smart Sensor Profile V2

The sensors used in industrial automation today use sensing elements based on a wide range of chemical or physical effects.

Physical or chemical measurement values (e.g. position, pressure, temperature or substance) are converted and passed on in a suitable form to data processing units such as programmable logic controllers.

Integrated microcontrollers enable these sensors to perform not only measured value conversion, but also a certain amount of preprocessing.

Most of these sensors are "switch sensors".

With the help of individual parameterization or "teach-in", the sensors receive information about their "switching mode" and their "limit values"

This can result in one or more pieces of information about the measured variable.

Depending on their functionality, these sensors can provide the following PLC inputs:

• Analog information for transmitting measured values such as pressure or temperature.

• Binary information for the transmission of a state or consumption of the PLC outputs.

• Binary information for the transmission of the switching state.

The purpose of Smart Sensor Profile Edition 2 is the additional profiles, which define a stricter behavior in connection with additional profile IDs.

When a device should be replaced with another, PLC programs which support a specific complementary ProfileID will remain unchanged.

Thus, should a device replacement occur, only the device identification within the port configuration needs to be changed.

Smart Sensor Profile Edition 2 specifies a number of fixed combinations that provide fixed functionality and are identified by an individual profile ID.

Smart Sensor Measurement Categories

Smart Sensor Profiles are defined independently of the physical or chemical properties being measured.
