SYSTEM

16.4 CPU Shared Memory

The CPU shared memory is for exchanging data between CPU modules, and consists

of 4,096 words between 0H and FFF

The CPU shared memory consists of four areas; the host PLC operation information

area, the system area, the automatic refresh area, and the user's free area.

An area consisting of the number of automatic refresh points from 800

is used as the

automatic refresh area when the automatic refresh of device data is set up.

The beginning of the user's free area starts from the address immediately after the end

of the automatic refresh area.

800

to 811

becomes the automatic refresh area if the number of automatic refresh

points is 18 (11

points,) and the area after 812

becomes the user's free area.

The configuration of the CPU shared memory and the necessity of accessing

sequence programs are shown in the illustration below.

1: Use the S. TO instruction to write the free user area of the host PLC from the

High Performance model QCPU.

The Motion CPU is not provided with an S. TO instruction, so that it cannot write

in the free user area of the host PLC.

For the writing method from the PC CPU module to the free user area of the

host PLC, refer to the manual of the PC CPU module.

2: To read from the High Performance model QCPU, use the FROM instruction or

intelligent function module device (U \G ).

Because the Motion CPU is not provided with the FROM instruction or

intelligent function module device, data cannot be read from the Motion CPU.

For reading from the PC CPU module, refer to the manual of the PC CPU

module.
