12.9 Memory Configuration and Data Process
The memory configuration and data transmission of Simple Motion module are explained in this section.
The Simple Motion module is configured of four memories. By understanding the configuration and roles of two memories, the
internal data transmission process of Simple Motion module, such as "when the power is turned ON" or "when the PLC
READY signal changes from OFF to ON", can be easily understood. This also allows the transmission process to be carried
out correctly when saving or changing the data.
Configuration and roles
The Simple Motion module is configured of the following four memories.
: Setting and storage area provided, Not possible: Data is lost when power is turned OFF.
: Setting and storage area not provided, Possible: Data is held even when power is turned OFF.
