Configuration
PSSu assignment in system environment A
It is not necessary to configure ST inputs in the PSSuniversal Configurator on the
PSS WIN-PRO system software, but ST modules can be selected and displayed.
The ST process image can be optimised by combining adjacent bits of the same type into
bytes.
If the status byte is configured, the ST process image cannot be optimised.
Further information on configuration is available in the PSSuniversal Configurator's online
help.
Addresses in the process image
The module occupies 4 consecutive bit addresses in the process image.
