Installing the PSSu system
4.1
Modular structure
The PSSuniversal is a modular, programmable system for controlling plant and machinery.
The PSSuniversal Configurator/PSS 4000 system software is available for configuration.
The PSSuniversal Assistant software/Tool Suite PAS4000 provides support when selecting
components. A PSSuniversal type system consists of:
}
One head module
}
At least one supply voltage module, if the head module does not have an integrated
supply voltage
}
Input/output modules for standard and failsafe applications
}
End bracket to secure the system at the start
}
Terminating plate with integrated bus terminating resistors and end bracket to secure
the system at the end
The head module:
}
Connects the sensor/actuator level for standard applications with standard fieldbus sys-
tems (e.g. PROFIBUS-DP)
}
Connects the sensor/actuator level for failsafe applications, e.g. with SafetyBUS p or
SafetyNET p
}
Co-ordinates the entire process data traffic
}
May have an integrated supply voltage for module supply and periphery supply
Supply voltage modules:
}
Consist of an electronic module and a base module
}
Are available for various functions
Input/output modules:
}
Consist of an electronic module and a base module
}
Are incorporated in a compact module
}
Are available for a wide range of input/output functions
}
Can be installed in any order
Base modules:
}
Are carrier units for the supply voltage modules and input/output modules
}
Are used to connect the field wiring
}
Are available in the following connection types:
– Spring-loaded terminals or
– Screw terminals
Electronic modules:
}
Are plugged into base modules.
}
Determine the function of the supply voltage or input/output module
}
Communicate with the head module via the module bus
Compact modules:
}
Incorporate base module and electronic module in one housing
