■ Overview
SlimLine modules of the S22.5 and S45 series
SlimLine S45 modules (left) and S22.5 modules (right)
The AS-Interface series of modules for the "SlimLine" control
cabinet with degree of protection IP20 creates space in the
cabinet and in distributed local boxes.
For these modules the priority was placed on a narrow type of
construction. They have a width of only 22.5 mm or 45 mm.
Standard sensors/actuators and the AS-Interface cable can be
connected using removable screw-type or spring-type termi-
nals.
Integrated adapters enable mounting onto a standard mounting
rail. Disassembly from the standard mounting rail is quick and
easy and requires no tools.
With an additional accessory (push-in lugs), the modules can
also be screwed on.
All modules are fitted at the front with LEDs which indicate the
module's status.
An addressing socket integrated at the front enables the module
to be addressed also when it is installed.
In addition to the digital input/output modules there are modules
of design S22.5 with special functions. These include:
• Counter module
• Ground-fault detection module
More information about these modules, see
• the section "Modules with special functions" on page 6/70

The new AS-Interface Specification 3.0 adds a number of
completely new features to the AS-Interface bus system. The ex-
tended address mode (A/B addresses) enables the connection
of up to 62 slaves on one AS-Interface network. With the ex-
tended address mode according to specification 3.0, four out-
puts are now possible for the first time even with A/B slaves
(instead of only three outputs possible up to now with specifica-
tion 2.1). Hence with full expansion of an AS-Interface network,
there are now 248 inputs as well as 248 outputs available on one
AS-Interface system.
Modules with four inputs and four outputs as A/B slaves accord-
ing to specification 3.0 are also available as SlimLine modules
S45.
Note:
Please note that the modules according to Specification 3.0 can
be used only with a new master according to AS-Interface
Specification 3.0 (e.g. the new DP/AS-i LINK Advanced or
IE/AS-i LINK PN IO) and that the cycle times for the outputs can
extend to max. 20 ms.
