Basic Process Redundant
The Basic model QCPU, Process CPU and Redundant CPU do not support the special function
modules.
Note9.11 Note9.11 Note9.11
The processing speed for intelligent function module devices is;
• The processing speed of read/write by the intelligent function module device is
slightly higher than that of read/write by the FROM/TO instruction. (For example,
"MOV U2\G11 D0")
• To conduct reading the buffer memory of the intelligent function module/special

function module
processing speed of FROM/TO instruction and processing speed of instruction to
setup the reference value.
(For example, case of "+ U2\G11 D0
POINT
When multiple intelligent function module devices are in a sequence program to
read/write the buffer memory data, the processing speed can be increased by
reading/writing data in one place of the program using the FROM/TO instruction.
