System description
Module bus
The module bus is formed by arranging the base modules together and connecting them via a mechanical latch.
` Data
2 independent bus systems are available for FS data and ST data. The data is processed in the head module.
` Module supply
Supply for the head module and the electronic modules. Various supply voltage modules are available for different functions (e.g. voltage refresh, separating the supply).
` Periphery supply
The supply for the actuators (load) or input test pulses is provided at the base module contacts, depending on the function of the electronic module. Various supply voltage modules are available for different functions. The connection on the module bus can be disconnected in order
to form supply groups. In this case it is necessary to use an appropriate supply module, which disconnects the supply (module supply, periphery supply and C­rail supply) to the preceding (left­hand) modules and provides a new supply to subsequent (right­hand) modules.
` C-rail
The C-rail is routed through all the base modules via the module bus. The C-rail is an additional power rail, which is attached to the base module connections. It is intended as an option, providing additional power if required. Access to the C-rail is available through the use of base modules which contain the letter “C” in their description (e.g. PSSu BP­1/8 S). The base module connections on which the C-rail is available are marked with a black bar across the whole connection level. I/O modules normally route the C-rail connections on connection level 3.
If the supply is separated on base modules containing supply modules, this is symbolised by the fact that only the right-hand connection on the connection level is marked with a black bar.

Explanation
Details are valid for designing a PSSu system with any combination of ST modules and FS modules, provided all the following conditions are met.
Details are valid for designing a PSSu system with ST modules only. Restrictions may apply, depending on the standard bus system that is used.
Details are valid for designing a PSSu system with FS modules only.
Details are valid for designing a PSSu system with dual-pole FS output modules only (e.g. PSSu E F DI OZ 2).
The load is determined by the current consumption of the head module and electronic modules that are used. If a heavier load arises, an additional supply module must be used to refresh the module supply. Further details can be found in the description of the relevant supply module.

Local enable principle
The new local enable principle technique means that outputs on failsafe output modules can now be switched via a standard bus system (e.g. PROFIBUS).
Configuration of the local enable principle
` Via the PSS WIN-PRO system
software
` By configuring FS output modules
for the relevant standard bus system (e.g. in the case of Profibus, included in the GSD file)
` By assigning an FS output to a bit
in the ST process image of outputs (ST-PIO). The FS output will therefore operate as an enable output.
` Ability to read the FS inputs via
the standard bus system.
Operation of the local enable principle
` The configured FS outputs are
driven via a standard bus system.
` Provided the enable output carries
a “1” signal, the configured FS outputs can be driven via a standard bus system. As soon as the enable output carries a “0” signal, the configured FS outputs are shut down safely. Control via the standard bus system is ignored.

Connection labelling on the base modules
The connections on the base modules are indicated via two-digit numbers. The first digit denotes the column on the module. The second digit denotes the connection level within the PSSu system.
Example: Colour marking of connection levels
Colour marking of connection levels
The colour marking on the different connection levels is helpful when it comes to wiring. Various colour markers are available to label the connection levels. For the connection diagram to remain consistent it makes sense to arrange I/O modules of the same type into groups (see example).
The connection levels are typically assigned as follows:
` Connection level 1 and 4
On I/O modules, connection levels 1 and 4 typically contain the module’s inputs or outputs. Marking in the example:
- Black [3]
` Connection levels 2 and 3
On I/O modules, connection levels 2 and 3 typically contain the common supplies (+24 VDC, test pulse outputs, 0 VDC). Marking in the example:
- Red [1]: +24 VDC/test pulses
- Blue [2]: 0 VDC

Separating supplies to form supply groups
Supply groups are formed by separating the 24 V supply (periphery supply) and, if necessary, also the 5 V supply (module supply). In this case it is necessary to use a supply module that disconnects the supply (periphery supply, C-rail supply and, if necessary, the module supply) to the preceding (left-hand) modules and provides a new supply to subsequent (right-hand) modules.
Provided an appropriate base module is used, in principle any electronic supply voltage module is suitable for separating supplies.
Principle: Formation of supply groups for periphery supply
In each case you should take note of the description of the relevant electronic supply voltage module.
For example, supplies can be separated on the following modules:
Modules

Installation
Mounting position
` A PSSu system should preferably
be installed horizontally on a vertical wall.
` If other mounting positions are
used (e.g. vertical installation), there will be certain restrictions with regard to
- Ambient temperature Optimum upward heat dissipation can no longer be guaranteed.
- Vibration and shock stress There will be increased requirements on the system fastenings: use additional metallic end brackets!
Mounting rail
` A PSSu system is designed to be
installed on a zinc plated DIN rail in accordance with DIN EN 50022. Dimensions: 35 x 7.5 mm or 35 x 15 mm
` Where vibration and shock stress
place increased requirements on the system fastenings, it is recommended that the mounting rail is screwed to the mounting plate approximately every 200 mm.
Module layout
` The first module on a PSSu
system is always a head module.
` A supply voltage module is always
connected to the right of the head module
- To supply the module electr­onics to the head module and subsequent I/O modules
- To provide 24 VDC for the periphery supply
` Next right it is possible to install
I/O modules for FS and ST applications.
- The I/O modules (input modules, output modules) can be installed in any order.
- I/O modules for FS applications and ST applications can be combined as required.
- In various applications it makes sense to combine specific modules into groups.
- It is not possible to mix base modules with screw terminals and cage clamp terminals.
- The max. number of I/O modules is determined through the defined system limits.
` Supply voltage modules may be
required to refresh the supply to the module electronics. This can be determined through the defined system limits.
` To form supply groups, an
additional voltage supply module is required at the start of each group. The modules belonging to the supply group will then follow to the right.
` The final element in a PSSu
system is always a terminating plate, containing the bus terminating resistors.
` Various fastening elements are
used at the start and end of the system to secure the system on the mounting rail:
- End bracket at the start of the system
- Plastic version (standard)
- Metal version
(increased requirements with regard to vibration and shock stress)
- End bracket at the end of the system
- Plastic version (standard)
- Metal version
(increased requirements with regard to vibration and shock stress)

Mechanical coding
Electronic modules have a two-part coding element. The first time an electronic module is plugged into a base module, one part of the coding element remains on the electronic module, while its counterpart is fixed on to the base module.
The coding element is designed to help prevent plugging errors (e.g. when exchanging modules).
` Once a base module has been
coded, only electronic modules with the same coding can be inserted.
` If a new electronic module is to be
plugged into a base module that has already been coded, you will initially need to remove the coding counterpart on the electronic module.
