The Q series has the multiple PLC system function that also permits PLC, process, motion, and personal computer CPUs to be loaded

together, enabling utilization of their respective strong points and construction of an optimal system. A single process CPU can perform both

fast loop control and sequence control simultaneously.

The motion CPU uses SSCNET that rapidly controls up to 96 axes in a single system and saves wiring. A personal computer CPU can

access I/O and intelligent function modules from a C-written application program. It can also communicate with higher level devices from an

Ethernet communication port.

Multiple Q series PLC CPUs can be used together to allow a single system to exercise controls different in tact time, e.g. sequence control

and data processing.

The GOT-A900/F900 series can be connected by the CPU RS-232 port.

Connected with a serial communication module, Ethernet or further a Q series

high-speed bus, the GOT-A900 series can achieve fast response.

The GOT-A900 series is also compatible with a multiple PLC system. By specifying

the CPU No. at the time of monitor device setting, you can monitor the data of each

CPU on a single screen. You can also monitor the ladder of each CPU.

Functions

The Q series PLC achieves analog processing, loop control and simple engineering necessary for Process Control.

1. A single high-reliability process CPU includes fast loop and fast sequence control functions.

2. The high-function analog module includes channel isolation, high accuracy, high resolution and wire disconnection detection functions.

3. The channel-isolated pulse input module (QD60P8-G) enables precision counting. (Refer to page 14.)

Basic PID

2-degree-of-freedom PID

A motion CPU is good at

advanced, complex motion

control. It can speed up motion

operation cycles and control up

to 32-axis per CPU. The

Q173CPU (32-axis) and

Q172CPU (8-axis) are available.

(For details, refer to the Q series

motion controller manual.)

The process CPU includes

process control instructions that

achieve high-level loop control,

e.g. two-degree-of-freedom

PID, sample PI and auto tuning

instructions. (For details, refer

to the MELSEC process control

manual.)

If load in excess of a CPU's processing capability is applied to a

large scaled system due to a large program size, using multiple

CPUs to distribute the load improves the overall performance of

the system.

When one process requires fast processing and the other does

not, they can be handled respectively by two CPUs, providing

stable (unaffected by the other process) and rapid control.

enable direct wiring of sensors (flow

meters, pressure gauges, other sensors)

and control devices (control valves). (An

external isolating amplifier is not required

between the analog modules and the

external devices.)

This reduces total hardware and working

costs.

modules (Q64TDV-GH, Q64TD) are also

available. The Q64TDV-GH also supports
