Associated product(s)
Several failsafe digital signals shall be monitored and failsafe actuators shall be controlled in a plant. Depending on importance and failure risk, there are several options of wiring and voting the signals.
The voting can, for example, be realized in the digital input modules and/or in the CPU. The various possibilities of wiring and voting failsafe signals are illustrated in this application example. Additional the wiring and voting of failsafe outputs are illustrated too.
Featured architectures
- One sensor (1oo1)
- Two sensors (1oo2) – voting in the F-DI
- Two sensors (1oo2) – voting in the user program
- Control of actuators
