4.1.1 Functions
Functions4-][Funktionsbeschreibung Module Supply
Module supply
The module supply provides the module with voltage.
][Funktionsbeschreibung_Peri FS-Eingang
Periphery supply
The module switches the periphery supply from the module bus to the
base module terminals.
The periphery supply is used to supply or provide test pulses to the
input devices.
][Funktionsbeschreibung_Ein FS
Inputs
The input status is signalled to the head module via the module bus.
Test pulses can be used to check the inputs for shorts across con-
tacts and correct functionality.
The inputs have input filters.
][Funktionsbeschreibung_Takt 2 x
Test pulse outputs
2 test pulse outputs that use different test pulses (test pulse 0, test
pulse 1)
Short circuit-proof
Current limitation
Test pulses can be switched on or off.
Test pulses are switched off in the default setting.
When test pulses are switched off, the periphery supply is constantly
available at the outputs.
Detection of shorts across contacts
The test pulses are used to detect shorts between inputs. Shorts be-
tween inputs are detected when
– the test pulses are different (test pulse 0, test pulse 1) or when
– the test pulses originate from other modules on a PSSu system.
Shorts between inputs of the same module with the same test pulses
will not be detected.
][Funktionsbeschreibung_Zusatz Eingang
Signal detection at the inputs
A signal (“0” signal or “1” signal) is always ignored if it is present for
less than the minimum processing time (see Technical details).
A signal is always detected and transmitted to the process image (PII)
if it is present for longer than the maximum processing time plus the
scan time of the module bus (t2 + t3, see diagram and Technical de-
tails).

Read access through the standard bus system
(configured per module):
“R” configuration
Allocation of a test pulse output to an input
(configured per input)
Optimisation of ST process image by combining adjacent bits of the

INFORMATION
The PSSuniversal Configurator on the PSS WIN-PRO system
software must be used to define the I/O-Groups to which FS
inputs and outputs belong (SafetyBUS p). The PSSu can be
divided into sections A and B for this purpose. All the FS inputs
on a PSSu always belong to section B.
Section A and section B on a PSSu may belong to different I/O-
