4.2 Configuration
4.2.1 PSSu assignment in system environment A
Functions for the FS inputs of a PSSu are defined in the PSSuniversal Configurator on the
PSS WIN­PRO 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 WIN­PRO system software
must be used to define the I/O­Groups 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/O­Groups.
Further information on configuration is available in the PSSuniversal Configurator's online
help.
4.2.1.1 Addresses in the process image
The module occupies 4 consecutive bit addresses in the process image. The process im­
age in which the inputs are shown depends on the configuration.
