4.2 Module features
4.2.1 Functions
Module supply
}The module supply provides the module with voltage.
Signals at the output
}"0" signal (0V) at the output:
– Output is high impedance
– No current to the load
}"1" signal (+24V) at the output:
– Output is low impedance
– Current is supplied to the load
Periphery supply
}The module routes the periphery supply from the module bus to the base module ter-
minals.
}The periphery supply is used to supply the outputs.
Outputs
}The head module sets the output status via the module bus.
}The max. capacity at an output depends on the load (see characteristic). Connecting a
higher capacity may lead to an error.
}Operation with electronic contactors has not been tested and may lead to errors.
Please contact our Customer Support team if you are using electronic contactors.
Output test

Function description
Operating Manual PSSu E F 2DO 2(-T)(-R)
21322-EN-07 14
}Outputs that are switched on are checked via regular off tests.
– Test pulses for outputs that are switched on: see Technical details"
– Outputs that are switched on are switched off for the duration of the test pulse.
– The load must not switch off because of the test.
}Outputs that are switched off are checked via regular on tests.
– Test pulses for outputs that are switched off: see Technical details"
– Outputs that are switched off are switched on for the duration of the test pulse.
– The load must not switch on because of the test.
Excluding individual outputs from the output test:
}If a plant is particularly sensitive to the test pulses, they may be switched off for indi-
vidual outputs.
}The test must be replaced by other measures, depending on the safety requirement.
}When test pulses are switched off:
– The correct switch status is always checked.
– The output's ability to switch will not be detected until the next time the output is
switched on/off.
Testing for shorts
}A test is regularly carried out to check for shorts between the outputs.
}For applications in accordance with Category 4, PL e and SIL 3, detection of shorts
between contacts must be guaranteed either via the on/off test or through other meas-
ures (e.g. asynchronous switching). A short between contacts must be simulated during
commissioning.
WARNING!
When wiring an output with capacitance it is essential to note the pulse dur-
ation, repetition period and scan time of the power-up test, otherwise the
load may switch on unintentionally.

4.3 Configuration
4.3.1 PSSu assignment in system environment A
Functions for the FS outputs 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):
Configuration "R"
}Read/write access through the standard bus system
(configured per FS output):
"&" configuration (local enable principle)
}Optimisation of ST process image by combining adjacent bits of the same type.
Configuration "*"
}Exclude individual outputs from the output test
(configured per FS output).
4.3.1.1 Addresses in the process image
The module occupies 2 consecutive bit addresses in the process image. The process im-
age in which the outputs are shown depends on the configuration.
With write access ("&"), the Bits in the ST-PIO are used to switch the FS outputs with the
local enable principle.

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.
