Retrofittable IIoT module for control valves

08 January 2024

Schubert & Salzer Control Systems has introduced a retrofittable Industrial Internet of Things (IIoT) module for control valves which is said to make monitoring and predictive maintenance simple even for plant operating companies without special prior knowledge.

The new plug & play solution can be easily fitted to existing Schubert & Salzer positioners. The modules are then immediately able to make their data available via a smart device connection. Instead of retrieving data via cable or Bluetooth, the data is now available remotely.

An important aspect of the new development was security against cyberattacks and unauthorised access. Communication between the IIoT module and the positioner has been deliberately designed as a one-way street. The module is controlled 100% by the controller. It only sends data to the cloud that the controller actively provides. The module itself cannot request data from the controller or actively execute commands.  It is also not technically capable of making changes to the controller.
