10.5 Intelligent Function Module Devices (U \G )

10 - 38
(1) Definition
(a) The intelligent function module devices allow the Basic model QCPU to
directly access the buffer memories of intelligent function modules which
are installed at the base unit.
(b) Intelligent function module devices are designated by the intelligent function
module input/ output No., and the buffer memory address.
Designation method: U \G
When digital output values of channels (CH.1 to CH.4) of the Q64AD Type
Analog-Digital Conversion Module (X/Y0 to X/YF) installed in Slot 0 of the main
base unit are stored in D0 to D3, the output/input number and the buffer memory
address are specified as shown below.
(2) Processing speed
The processing speed for intelligent function module devices is;
(a) Read/write from/to the buffer memory of the intelligent function module is
slightly faster than the "processing speed of FROM/TO instruction". (For
example, "MOV U0\G11 D0")
(b) When using a single instruction to perform read from the buffer memory of
the intelligent function module and another processing, use the sum of
"processing speed of FROM/TO instruction" and "processing speed of
instruction" as a guideline.
(For example, "+ U0\G11 D0 D10")
If the same buffer memory of the same intelligent function module is used
two or more times in a sequence program, the processing speed can be
increased by using the FROM instruction to read that buffer memory data to
a Basic model QCPU device.
REMARK

manual for the intelligent function module in question.
