What's System Data Area? |
|
The system data area (LS0 to LS19) stores GP's basic information such as GP's watch, the currently displayed screen number.
As the LS area cannot be monitored directly by the PLC's ladder program, it is assigned to the device called PLC's data register or data memory and the contents of the system data area can be read or written. |
