Safety architectures
Redundant safety discrete inputs can be connected to 1 or 2 sensors. The 2 input
channels should preferably be located on different input modules.
If a single sensor is used, the modules share the same process power supply.
The wiring must be defined to suit the conditions of use of the modules (input
characteristics on short circuit, open wire, 0 and 1 logic levels, voltage and current)
as specified in the Quantum Hardware Reference Guide.
Block diagrams:
Function block S_DISIL2 can be used for selecting data from the 2 redundant
discrete inputs and to supervise the state of the inputs.
For high availability discrete outputs, the 2 outputs must be on separate modules,
wired in parallel and connected to 1 actuator.
Block diagram:
A function block is not necessary because the same signal from the CPU is
connected to both outputs.
