WithallPCD2sexceptthePCD2.M110,itispossibletodetectthepresenceof
an expansion unit.
InconjunctionwithPCD3.C200Modulesitisalsopossibletorecognizewhetherthe
closest C200 to the CPU is connected to the supply.
Ajumpercanbeusedtocongurewhetherthemonitoringisactivated.
