D.2 Terms relating to AS-Interface
APF
AS−i−Power Fail. Flag or LED display that indicates that the power supply on the
AS-i cable is too low or has failed (for example failure of the AS-i power supply
unit).
AS-i (AS-Interface)
Actuator-sensor interface. A network system for the lowest field area of the
automation range. It is suitable for networking sensors and actuators with control
devices. (previously: SINEC S1)
AS-i A/B slave
AS-i A/B slaves use the extended addressing mode. Pairs of A/B slaves can be
assigned to one address on the AS-Interface; by organizing addresses in this
way, up to 62 AS-i A/B slaves can be attached to the AS-Interface.
