All compact modules are placed on a mounting plate. The mounting plate
takes the AS-Interface cable and keeps it in place. Polarity reversal is not
possible due to the profile of the cable. The compact modules are simply
hooked on at the top of the mounting plate and secured with just one screw.
When you secure the modules, contact is made with the AS-Interface cable.
You do not have to strip or screw on the cable.
All the modules are mechanically and electrically coded.
The coding system prevents errors occurring in the event of replacement. At
replacement, only one module of the same type can ever be mounted. This
stops digital or analog modules (or even inputs or outputs) getting mixed up.
To participate in data transfer with the master, each node must be assigned
an address before commissioning of the AS-Interface network. Addressing
devices are available for this.
There is an additional feature which makes new Siemens modules even
more user-friendly: the addressing socket.
Using this socket you can address a module after it has been installed. It is
not necessary to unscrew the module. Installation can be carried out in the
system by personnel who are not familiar with the AS-Interface. The com-
missioning engineer can address the modules easily when they are already
installed. For the first time, this type of addressing is also possible with
IP 67 protection.
The new generation of AS-Interface modules (compact modules, analog
modules, and SlimLine modules) has the new display system developed by
Siemens.
The status of a module is displayed by two LEDs lighting up continuously or
flashing.
This simple diagnostic feature directly on the module makes it possible for
the user to find the error quickly and efficiently. This in turn reduces down-
times.
All Siemens AS-Interface products are tested in acc. with the relevant
testing regulations in an accredited test laboratory and certified by the AS-
Interface association.
