Chapter 7 Module Control

This chapter explains the interface memory area of PF611/PF612 seen from S2T/S2E
application program.
PF611/PF612 allocates the sending and receiving data of the cyclic transmission to this
memory area. Also, the request/response text area between S2T/S2E and PF611/PF612 is
allocated on this memory area.
S2T/S2E application program accesses this memory area directly by READ/WRITE
instruction.
