4.2 Functions
Module supply
}The module supply provides the module with voltage.
Periphery supply
}The module switches the periphery supply from the module bus to the base module ter-
minals.
}The periphery supply is used to supply or provide test pulses to the input devices.
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 contacts and correct
functionality.
}The inputs have input filters.
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 on 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 between inputs are
detected when
– the test pulses are different (test pulse 0, test pulse 1) or when

Function description
Operating Manual PSSu E F 4DI(-T)(-R),
21310-EN-08 13
– 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 detec-
ted.
4.3 Integrated protection mechanisms
When the PSSuEFPS1(-T) or PSSu E F PS2(-T)(-R) is used to supply the system, the
module supply is buffered for 20ms if the supply voltage is interrupted.
}Test pulse signals are always buffered for 20ms.
The module provides the following diagnostic data:
}Start-up error
}Configuration error
}FS communication error
}Bus termination error
}Temperature error: Too warm
}Test pulse error
}Input error
4.4 Reaction times
Information on the reaction times of the inputs can be found in the "PSSuniversal" System
Description and the System Description "Automation system PSS 4000".
4.5 Configuration
4.5.1 PSSu assignment in system environment A
Functions for the FS inputs of a PSSu are defined in the PSSuniversal Configurator on the
PSSWIN-PRO system software:
}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 same type.
“*” configuration
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 be-
long (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-Groups.

Further information on configuration is available in the PSSuniversal Configurator's online
help.

5.2 Installing the base module
Prerequisite:
}The head module must be installed.
}If the head module does not have an integrated power supply, a supply voltage module
must be installed to the right of the head module.
Please note:
}For mechanical reasons it is not possible to mix base modules with screw terminals and
base modules with cage clamp terminals.
}All contacts should be protected from contamination.
}The mechanics of the base modules are designed for 50 plug in/out cycles.
Procedure:
}We recommend that you wire up the base modules before inserting the electronic mod-
ules.
}Slot the groove on the base module on to the mounting rail from below [1].
}Push the base module back [2] until you hear it lock into position.
}On the mounting rail, slide the base module to the left until you hear the two lateral
mounting hooks on the adjacent module lock into position [3].

5.3 Inserting and removing an electronic module
Please note:
}Only insert on to base modules that are already installed.
}Preferably these base modules should be ready wired.
}Electronic modules with outputs may only be inserted and removed when the load is
switched off. Unforeseeable error reactions may be triggered if modules are inserted
and removed under load.
}When an electronic module is plugged into a base module for the first time, one part of
the coding element remains on the electronic module, while its counterpart is fixed on to
the base module. This is how the base module is coded.
}The mechanics of the electronic modules are designed for 50 plug in/out cycles.

5.3.3 Changing an electronic module during operation
It is possible to change an electronic module during operation. The configuration data is re-
tained when a module is changed.
Effects:
}System environment A:
– In the event of a potential FS communication error, the FS section of the PSSu sys-
tem and all relevant I/O-Groups (SafetyBUS p) switch to a STOP condition.
}System environment B:
– All FS hardware outputs on the PSSu system switch to a safe condition.
– The substitute values are used for the modules' FS outputs, with Valid Bits =
FALSE.
CAUTION!
Sparking can cause interference and errors!
Only change the module when the load is switched off!
