2.3 Information for the beginner
AS-Interface is a field bus system for industrial application whose advantages include no only its ease of
handling in planning and application but also the good overview of the total system.
To make the system even easier and safer for beginners to use, we recommend proceeding as outlined
in the checklist below :
Work phase Questions Note
Planning How many I/O's are re-
quired in total ?
This determines whether one or more AS-Interface sys-
tems will be needed for realization.
Planning How great is the system
power requirement ?
Important for the selection of suitable system power
supply units. Never switch AS-Interface power supply
units in parallel !
Planning How large is the total
scope of the system ?
Repeaters must be used if the sum of all cable lengths
exceeds 100 m.
Configuration How are the modules to
be assigned ?
To avoid addressing errors, create an assignment
scheme and carefully label all addressed modules ac-
cordingly !
Installation Where will the modules be
installed ?
Depends on the module enclosure type : either in a
switch cabinet or terminal box. Place modules of enclo-
sure type IP 67 close to sensors and actuators for the
sake of greater efficiency.
Setup How will the system con-
figuration be executed ?
In configuration mode (master operating mode) the de-
tected slave profiles are automatically read in by the
master.
Setup Have all slaves been de-
tected by the master ?
When all slaves have been detected, the master should
be switched into protected operating mode.
This enables exhaustive diagnostics.
Setup How can a simple I/O
function test be performed
?
Quick and straightforward with special, easy to use
setup tools

or via the gateway with graphics display.
Alternatively with the PLC Software Tool.
