All base modules have a standardised socket board with potential-free outputs. These
can e. g. be used as alarm outputs. The control is realized over the visualization software
alpha data view. This interprets the received data and sends a command for the activa-
tion of the alarm outputs to the base module, if required. Following, the Pin assignment
of the socket board is described.
