Digitisation of measuring probe for IO-Link

IO-Link has become established as an intelligent interface for integrating smart sensors and devices in various industries. Nevertheless, conventional temperature probes (Pt100 / Pt1000 elements or thermocouples) are still widely used in many machines and systems, which have to be connected to the central controller. With the new IO-Link measuring modules, up to four temperature probes can be connected to an IO-Link master port, optionally in 2-, 3- or 4-wire connection technology. The pin configuration of the M12 connector can be customised using the IO-Link parameter setting.
Adjustment of the measured value

Especially when measuring temperature with thermocouple elements, the metals used in the cables and contacts have a considerable influence on the measured value. The measured value can therefore be adjusted to the measuring line used with the "Cold junction offset" and "Temperature zero point calibration" parameters.
To cover a large number range with high resolution, the measured value is displayed as a "floating number” in the process data.
