5.1.2.1
General description of the AS-i functions and addressing of these
The module has an AS-i safety participant that fulfills 3 different functions.
Each function is described by an own AS-i address.
The addressing of the individual slaves is described in chapter 5.1.2.3.
5.1.2.1.1 Safe outputs
The participant has 2 safe outputs at the 1st address (in the following the address is described with X),
which are used in the function depending on the diagnostic setting for switching on and off including
reversing operation of a three-phase motor.
