14.1.4

Data communications without using auto refresh

The following areas in the CPU shared memory are used for data communication without use of auto refresh.
1) User setting area
This area is available for CPU modules.
Addresses of the user setting areas vary depending on the CPU module used.
For details, refer to the following.
Page 252, Section 14.1.1
2) User setting area in the multiple CPU high speed transmission area
This area is only available for the following CPU modules.
• Universal model QCPU (except for Q00UCPU, Q01UCPU, and Q02UCPU)
• Motion CPU (Q172DCPU(-S1), Q173DCPU(-S1), Q172DSCPU, and Q173DSCPU)
• C Controller module (Q24DHCCPU-V, Q24DHCCPU-VG, Q12DCCPU-V (Basic mode), and Q12DCCPU-V
(Extended mode))
Transmission area address for each module varies depending on set parameters (multiple CPU high speed
transmission area settings).
For details, refer to the following.
 Page 261, Section 14.1.3
