Sample Program for DP Communication to a CPU 224
A sample program in Statement List for a CPU 224 that uses the DP port
information in SM memory is shown in Figure A-32. Figure A-33 shows the same
program in ladder logic. This program determines the location of the DP buffers
from SMW226 and the sizes of the buffers from SMB228 and SMB229. This
information is used in the program the copy the data in the DP output buffer to the
process-image output register of the CPU 224. Similarly, the data in the
process-image input register of the CPU 224 are copied into the V memory input
buffer.
