Specifications

Advanced multi-disciplinary automation that reaches beyond the
The Q series can combine multiple CPUs together on the same
system to build the required application configuration. Control of
I/O modules can be segmented between different CPUs. CPUs
communicate with each other via shared memory, and can
increase system performance by distributing tasks between
different CPUs. A variety of methods exist for controlling the
methods by which CPUs communicate, but in each case the
development effort is simplified by available software tools.
Multiple CPU System Configuration
The Q series multiple CPU system function allows PLC CPU,
process, motion, and personal computer CPUs to be mounted
together, enabling utilization of their respective strong points and
design of an optimal system.
Integration of Process CPU, Motion CPU, and PC CPU
Process CPU
Q series offers a feature that rivals those of costly DCS systems at a fraction of the cost. Q Series is adept at the automation of
process systems with the simple addition of one or more process CPUs to the controller. The process CPUs are complemented by
a range of channel-isolated high resolution analog I/O modules with online change (hot-swap) capability, and the PX Developer
function block programming software environment. (Refer to the “MELSEC Process Control Catalog” for more information on the process CPU.)
¡The “Process CPU” builds on the capability of the equivalent sequence CPU with the addition of an array of powerful
process instructions.
¡“Channel-isolated high resolution analog module” further enhance process control using the PLC.
¡Combine the Process CPUs with the redundant network capabilities of the MELSECNET/H control level network.
This offers high performance, robust, and deterministic communications between multiple Q Series systems,
regardless of their assigned control tasks.
Process Control
Install up to 4 CPUs.
Modules are managed CPU-by-CPU.
Use standard Q series I/O and intelligent function
modules (Note 1).
Note 1)
There are restrictions on the number and versions for intelligent
function modules. Check details in the Q series data book.
Note) Only the following combinations can be used with the Basic Model.
· Basic Model CPU + Motion CPU
· Basic Model CPU + PC CPU
· Basic Model CPU + Motion CPU+ PC CPU
* SSCNET is a network where the motion CPU and servo amplifiers are connected with
minimum wiring by high-speed serial communication.
