Term
Description
Master
Component for data transmission that controls the logical and temporal
behaviour on the AS-i line.
Safety monitor
Component that monitors the safety-oriented slaves and correct
functioning of the network. Configuration and commissioning of the AS-i
safety monitor take place via a PC/notebook with the configuration
software ASiMon.
Slave
Component for data transmission that is addressed by the master cyclically
via its address and only then generates an answer.
ASiMon
Configuration software for the AS-i network

Note
Specifications on the design and addressing of your bus system can be found in the
manual for the AS-Interface master and AS-i safety monitor.
A detailed description of all functions can be found in the user manual of the configura-
tion software ASiMon.

Brief description AS-i
The actuator sensor interface (AS-i) is a system for networking sensors and actuators on the lowest
level of the automation hierarchy. It is a non-proprietary open bus system and enables transfer of data
and energy on just one line. This simple handling permits an efficient configuration with simultaneously
reliable performance. The network topology of the AS-i system can be expanded as desired without
trouble.
An AS-i network consists of a control unit, a so-called master and the associated sensor and actuator
components, namely the slaves. The master cyclically polls all configured slaves and exchanges input
and output data with them. A telegram consists of 4-bit user data. The master communicates with the
stations with a serial transmission protocol.
