Can I use a PCD4.C225 together with a PCD2.M5xx0?
FAQ #101386
No, the PCD4.C225 is not supported by a PCD2.M5xx0 CPU. Due to the higher processing speed of the PCD2.M5 (compared to e.g. a PCD2.M150) it can not be guaranteed that the I/O modules are correctly accessed.
Why is this fact not stated in the manual for the PCD4?
In the manual for the PCD4 (27/734) there is not information regarding this restriction (it is only stated that a PCD2.M110 can not be used togheter with the PCD4.C225, and that no H-Modules or W1/W2/W3 modules can be used on the PCD4.C225).
The reason therefore is that at the time the manual has been created the PCD2.M5xxx did not exist. As it is no longer possible to buy PCD4.C225 extensions, the manual will not be update in future.
