Why do the output of the PCD2/3.W6x5 not deliver stable signals?

FAQ #102014

Depending of the hardware version of the W6x5 module and the I/O slot where the W6x5 module is plugged in, it’s possible that the analog output signal supplied from the W6x5 is not stable and is oscillating.

Symptom
The outputs of the PCD2/3.W6x5 do not deliver stable signals when placed on I/O slot 15 if hardware version B of the W6x5 is used.
If FBoxes are used for writing to the outputs, the FBox indicates temporarily an error.

Reason
The W6x5 modules with hardware version B are not correctly handling the Watchdog output (O 255).
Note that this is only the case if the module is placed on I/O slot 15 (base address 240). On all other slots the modules work correctly.

Solution
This problem is solved with hardware version A or C and newer of the PCD2.W6x5 or PCD3.W6x5 respectively.
