ID key-operated switches replace the use of passwords in human-machine-interfaces (HMI).
By Martin Brown, product manager Siemens
Human-Machine-Interfaces (HMIs) are dashboards that act as an interface between a user and a machine or device. They are designed to present information in a graphical format about the status of a process to an operator. HMIs can be password protected to only give authorisation and access to operators with the correct security clearance. However, a growing and recurring problem has been the loss or misplacement of these critical passwords, causing a host of delays.
