3.1 System overview
The PCD2.M5_ series is basically a combination of the PCD2 housing design
and circuitry with extensive compatibility and ease of upgrading along with PCD3
technology. The proven functions of the PCD2 series have been supplemented with
newfunctionssuchasUSBand"onboard"Ethernet,andthefacilitytouseashcards
and/orfutureSDmemorycards(forprogrambackup,lesystemforwebpages,data,
documents,etc.).ForeasylabellingoftheI/Osignals,therearepreprintedsheets
that can be protected by the transparent covering. I/O modules can be reconnected
or replaced without removing the central housing.
The circuitry and labelling have been completely revised. When I/O modules are
replaced, the electronic components on the CPU are protected. However, the I/O
modules themselves must not be plugged in or removed with the power on, the
supply voltage and the external +24 V must be disconnected. As with the PCD3, the
CPUhasnojumpers;alltherequiredfunctionshavetobeconguredin"Hardware
Settings".Theunitprovides4integratedportsandtwoRJ-45Ethernetsockets,
including switch. These make the PCD2.M5_ an extremely powerful communication
system.FTPandwebaccessarealsosupporteddirectlyviahttp.
Onthemotherboardtherearealso6digitalinputs(4interruptinputsoroneencoder
connection)and2outputs.Theoptiontoconguretheinputsasinterruptorencoder
inputsandtheoutputsaspulse-width-modulated(PWM)meansthatthePCD2.M5_
can be used as a "low-cost solution" for machinery and systems.
