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.
