The memory configuration and data transmission of the Motion module are explained in this section.
The Motion module is equipped with four memories. By understanding the configuration and roles of the four memories, the
internal data transmission process of the Motion module, such as "when the power is turned ON" or "when the PLC READY
signal [Y0] 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 Motion module is equipped with the following four memories.
: Setting and storage area provided, Not possible: Data is lost when power is turned OFF.
