3.5 Precautions for System Configuration
(2) Modules that have restrictions when used with an Universal model QCPU
For modules that have restrictions when used with an Universal model QCPU, refer to the following manual.
QnUCPU User's Manual (Function Explanation, Program Fundamentals)
(3) Combinations of power supply modules, base units, and QCPUs
There are some restrictions on combinations of power supply modules, base units, and QCPUs. ( QCPU
User's Manual (Hardware Design, Maintenance and Inspection)
Ex.
Redundant power supply modules can be mounted only on redundant power main base units or
redundant power extension base units.
(4) Precautions for using a QCPU of function version A
If a QCPU of function version A is used in a multiple CPU system, an error occurs. To configure a multiple CPU
system with QCPUs, use CPU modules of function version B or later.
(5) Precautions for using the high-speed interrupt function
A High Performance model QCPU and High-speed Universal model QCPU support the high-speed interrupt
function.
If the parameter with the high-speed interrupt fixed scan interval setting is written, the functions of the CPU
module are partly restricted. The restrictions differ depending on the CPU module used. ( User's Manual
(Function Explanation, Program Fundamentals) for the CPU module used)
Note that the above restrictions do not apply to the High Performance model QCPU with a serial number (first five
digits) of "04011" or earlier because the module ignores the high-speed interrupt fixed scan interval setting.
(6) Precautions for using a Motion CPU (Q172DCPU(-S1), Q173DCPU(-S1),
Q172DSCPU, or Q173DSCPU)
The Q172DCPU(-S1), Q173DCPU(-S1), Q172DSCPU, or Q173DSCPU can only be mounted on a multiple CPU
high-speed main base unit.
Note that do not mount any Motion modules controlled by the Motion CPU in slot 0 to 2 of the multiple CPU high-
speed main base unit.
