The PFC‘s process image contains the physical data of the I/O modules in
memory words 0 to 255 and 512 to 1275.

(1) Reading data of the input modules is possible from both the controller’s

CPU and from the fieldbus master (See Figure 3-8).

(2) In the same manner, writing data to output modules is possible from both

the controller’s CPU and from the fieldbus master.

The controller’s process image also contains variables called “PFC Variables”.
These variables are allocated based on the fieldbus protocols. The MODBUS
TCP PFC variables are stored in memory from word 256 to 511. Ethernet IP
PFC variables are stored in memory from word 1276 to 1531. The memory
area above word 1531 is reserved for future protocols.

(3) The PFC input variables are written into the input memory space from the

fieldbus master and can be read by the controller’s CPU for further
processing.

(4) The variables processed by the controller’s CPU , via an IEC 61131-3

application program, can be written to the PFC Variables and then read by
the fieldbus master.
