- 12 13.3 Data Communications Using CPU Shared Memory
The C Controller module can exchange data with CPU modules using the CPU
shared memory.
Use the bus interface functions when creating user programs of the C Controller
module.
The following describes the methods for data communications using the CPU shared
memory.
(a) Data communication methods using the CPU shared memory
There are the following two kinds of the communication methods.
• Using the auto refresh of programmable controller CPU and Motion CPU
• Not using the auto refresh of programmable controller CPU
(b) Selection of a data communication method
For data communications using the CPU shared memory, select a method that is
appropriate to the relevant CPU modules.
The following table lists the availability for each type.
Table 13.7 Availability for each data communication type
Using auto refresh
For the structure of the CPU shared memory of the C Controller module, refer to the
following.
