Chapter 7 Memory Configuration and Data
Process
The memory configuration and data transmission of Simple Motion module are explained
in this chapter.
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.
