1oo1 evaluation
Type of sensor evaluation. With 1oo1 evaluation, the sensor exists once. The sensor is
connected to the F-module over a single channel.
1oo2 evaluation, equivalent
Type of sensor evaluation. With 1oo2 evaluation, two input channels are occupied by one
two-channel sensor or by two single-channel sensors. The input signals are compared
internally for equivalence.
AS-i (AS-Interface)
Actuator-sensor interface. A networking system for the lowest field level of the automation
level. The networking system is suitable for networking sensors and actuators with control
devices (previous designation: SINEC S1).
AS-i A/B slave
AS-i A/B slaves use the extended address range. You can assign two A/B slaves as a pair to
an address on AS-Interface. Because of the address organization, you can therefore connect
up to 62 AS-i A/B slaves to AS-Interface.
AS-i analog slave
AS-i analog slaves are AS-i slaves that exchange analog values with the AS-i master.
AS-i master
The AS-i master monitors and controls binary or analog sensors and actuators via
AS-i modules or AS-i slaves.
AS-i slave
All devices that can be addressed by an AS-i master are referred to as AS-i slaves. AS-i
slaves are distinguished according to their design (AS-i modules as well as sensors or
actuators with integrated AS-i connection) and their addressing mode (AS-i standard slave
and AS-i A/B slave with extended addressing mode).
AS-i standard slave
The AS-i standard slave occupies one address on AS-Interface; because of to the address
organization, up to 31 AS-i standard slaves can therefore be connected to AS-Interface.
