In some (very rare cases) the clock of a PCS can not been written, and the shown time always is the 1.01.1990. After switching the PCS off and on again, the problem disappears.
An incompatibilty between old hardware versions of the PCD7.D23x and the HMI Editor distributed together with PG5 1.4.200 can cause the PCD7.D23x to jump back to the root menu while browsing the menu
In some cases it can happen that the PCD3.F180 (produced between 2006 and Febrauary 2007) works well for a certain time but suddenly stops communicating. This behaviour is related to the hardware vers
On PCD1.M1x0 or a PCD2.M110/120 with old firmware version the CPU won't go in run anymore after downloading the project with PG5 2.0.110.
Each new F-Box has the name Module. That is the reason for the multi-defined symbols.
An EPROM was created in the same way as EPROMS for Classic PCDs are created, but it doesn't work.
As the HMI Editor uses a library called SSTree.ocx that can also be used by other applications, version incompatibilities can cause problems on either of the concerned applications.
When mounting a PCD7.F120 into a PCD3.F121 / PCD3.F2xx or when using a PCD7.F120 on a PCD2.M5, the communication doesn't work. The reason therefore is an incompatibility between the PCD7.F120 and PCD3
In very special situations a PCD can get overloaded because of external influences in a way that a "KERNEL ERROR" or a "SWTO ERROR" (System Watchdog Timeout Error) is causing the PCD to restart automa
