Flash memory module
For the PCD3, different flash memory modules exist for different
applications. Partly, these modules are explicitly intended for one
purpose (e.g. file system memory). There are modules which
provide different types of memory (e.g. the PCD7.R562, which
includes 1 Mbyte of disk space for the DB backup, 128 Mbytes
for the file system, and memory for BACnet).

Flash
Most flash memory modules exist as a simple card (PCD7.Rxxx)
which can be plugged into slot M1 or M2 on a PCD3.M5xx0 or
PCD3.M6xx0 communication extension.
To enable use on a PCD3.M3xx0, the memory
modules PCD3.Rxxx are available, which
contain a PCD7.Rxxx and can be plugged into
an I/O slot (0 … 3) of a PCD3 CPU.

Any flash memory module that is suitable for user program backup (such as
a PCD7.R500) can be used as a flash card. If several suitable modules are
plugged in, the first module from the left is used for backup (slot M1, M2,
I/O slots 0, 1, 2, 3).
