ThermwareversionsforthePCD2.M110/M120aregenerallyupwardlycompatible
intermsofhardware,sooldCPUscanbettedwithnewrmware,inordertotake
advantage of new functions. This feature is highly valued, and we will try to retain it
for as long as possible; however, we cannot guarantee this.
At this point, the following known restrictions apply:
● HardwareversionD1fromJuly/August1995onlyworkswithfirmwareversion$34;
a firmware update is not possible with these controllers
● TheuseofintelligentcommunicationmodulessuchasProfibusDP,LONandEth-
ernet requires the minimum hardware and firmware versions. Please refer to the
manuals for the communication modules
Hardware version Hintroducedsignicantchanges:
● Hardwareclockonthebasecircuitboard(previouslyonthePCD2.Fxx0

● Internal5Vsupplynowratedupto1.6A(previously1.1A)
● Optiontoextendmemorywith4MBitchips(giving512Kbytes)
From hardware version J, the default set up of the base memory is 128 Kbytes
(previously 32 Kbytes).
