The automation system PSS 4000 stands for optimum interaction between hardware and software components, network devices and the real-time Ethernet. The system is characterised by the most varied functions and potential combinations, distinguishing it from classic automation. It has already been tried and tested in numerous applications in different industries. 

A new approach to automation systems!

Part of PSS 4000: The automation system PSS 4000 is characterised by a wide variety of potential combinations.

Due to the consistent distribution of control functions, projects with the automation system PSS 4000 can be implemented more easily and with greater flexibility than on previous systems. This is true for both stand-alone machines and interlinked plants.

  • Classic automation: One centralised control system monitors the plant/machine. All signals are processed via this control system; all sensors and actuators are connected to this control system. Thanks to decentralised I/O modules, some I/O functions can be transferred to the periphery, resulting in shorter paths for the sensor wiring, for example. Signals are not generally processed locally.
  • Consistent distribution of control functions: on the automation system the control functions are completely distributed and transferred to the periphery. Control data, failsafe data and states are exchanged and synchronised via the real-time Ethernet SafetyNET p. For the control function, therefore, it makes no difference where the respective program section is processed. Instead of a centralised control system, with our automation system you have a modular user program within a centralised project. This enables simple, standardised handling across the whole project.

Automation system PSS 4000 – Simplify your Automation™

Consistent distribution of control functions

With the automation system PSS 4000, control functions can easily be distributed directly to the periphery. This enables a centralised view of distributed automation structures - plus simple handling. As users you create a modular user program and therefore one project, through which all network subscribers are configured/programmed. Communication via the real-time Ethernet SafetyNET p also facilitates interaction between individual components. Network subscribers communicate with each other automatically - no additional configuration is required.


Merging of standard and safety

The merging of standard and safety is the focus of the automation system PSS 4000. Automation solutions, which as users you will find easy to operate, can be implemented for both standard and safety. The system is physically mixed but free from feedback. Programmers and users can combine configuration with function blocks and programming with source code in EN/IEC 61131-3 compliant editors. A key element here is the software platform PAS4000 with its various editors and blocks. Standardised editors are available, which can be used for automation as well as safety-related tasks.

With PAS4000 you have access to a standardised programming environment for configuration and PLC programming.


Hardware-independent operation

Previously, hardware needed to be selected at the start of the configuration/programming process. Subsequent modifications were very costly. With PSS 4000 it's different: Hardware can be selected and the program can be distributed to the hardware much later on in the process, as it is largely independent of the configuration stage. For example, if you establish that two control systems PSSuniversal PLC are reaching their functional limits, you can integrate a third control system. The user program can be redistributed without any significant effort.
