Safe Operating Mode Selection

Today's complex machines need the ability in certain situations to permit an operating mode at reduced speed or without monitoring of certain protective devices. This is now possible using so-called “safe operating mode selection.”

 

Bihl+Wiedemann makes it possible to easily implement safe operating mode selection up to PLe, with maximum convenience for the end user over a standard HMI. Access authorization for safe operating mode selection is supported using a normal safe key switch or an electronic key system.

Example configuration of the five safe operating modes according to the German Social Accident Insurance DGUV

Highlights of the Safe Operating Mode Selection

  • Safe operating mode selection over a standard HMI, e.g. a touch panel
  • Unrestricted configuration of five safe operating modes in six different instances
  • Simple implementation using a TÜV certified function module in the configuration software ASIMON360
  • Communication and detailed diagnostics made convenient via OPC UA (or also fieldbus)
  • Up to Performance Level e
  • Integrated into all newsafety monitors from Bihl+Wiedemann

Principle of the Safe Operating Mode Selection

The operating mode can be safely selected and activated using a standard HMI such as a touch panel. Access to this selection is by means of a key which is restricted to authorized persons. This can be either a mechanical or an electronic key (such as the Euchner EKS-FSA).

 

 

 

Safe Procedere

  • Displayed are the operating modes which can be activated with the current authorization.
  • Clicking on an activatable operating mode pre-selects it.
  • The pre-selection verified by the Safety Monitor is shown to the user for confirmation.
  • Confirming the pre-selection by clicking on it safely activates the corresponding operating mode in the Safety Monitor.

Individual Representation

  • User-friendly operating mode selection, uses freely programmable GUI on standard HMI 
  • Individual visualization of the system, its components and the respective selected operating mode
  • Detailed diagnostics over OPC UA, can be tailored to the respective application

Simple Configuration in ASIMON360

1. Activation of the safe operating mode selection in the ASi master

2. Selection of the access authorization type (key switch or Euchner EKS)

3. Allocation of the selectable operating modes to a maximum of five different electronic key levels (for EKS)

Full Flexibility for your Machine

  • Five different operating modes with different safety functions are freely configurable 
  • Independent, centralized configuration of up to six different instances, e.g. for six different system parts


This way, you can set different system parts independently to different operating modes.

Simple Integration

  • Simple to integrate via ASi using a key switch 

  • Integration and full support of the Euchner EKS (Electronic Key System) over the fieldbus
  • Communication with the HMI via OPC UA (or fieldbus
