Actuator Sensor Interface (AS-Interface or AS-i).is.a.system
for.networking.field.devices.such.as.sensors.and.actuators.
with.control.and.operator.interface.devices..AS-i.replaces.the.
extensive.parallel.wiring.often.used.to.connect.sensors.and.
actuators.to.controllers.with.a.simple.2-core.cable..The.cable.is.
designed.so.that.devices.can.only.be.connected.correctly.
