MELSEC iQ-R C Controller Module Programming Manual
Data can be read from/written to devices and buffer memory of a C Controller module by using a peripheral
device (such as CW Configurator).
Function list
The following table shows the functions used for accessing devices.
*1 CPU buffer memory cannot be accessed.
