Good to know

In case an Ethernet module PCD7.F65x is used on the PCD, the firmware 0F0 must not be used due to a bug in the firmware. Please update to version 0F1.

Please note that PCD7.R400 modules delivered after April 2010 require the PCD2.M170 firmware version 0F0 or later.

PCD3 LIO and PCD2.M17x: to use addresses in the range 256 to 511, CPU's with production date 0331or later have to be used, or older CPU's that have been returned for modification.
