3.2 Create cam data
3.2.1 Memory configuration of cam data
Cam data is arranged in the following 2 areas.
Previously written cam data can be used after turning the power supply OFF by writing data
in the cam storage area. Cam data should be written in the cam storage area for normal use.
It is possible to write directly to the cam open area via buffer memory when registering cam
data that exceeds the memory capacity in the cam storage area, etc. (Refer to Section 3.2.2
"Cam data operation function".) Writing must be executed to the cam open area due to
clearing the data at the power supply OFF.
Data is written by the following operations.
• Write with GX Works2
• When executing "write (Cam storage area)" with the
cam data operation function
Data is written when the cam auto-generation request
is executed. (Cam auto-generation function)
Cam data is transmitted from the cam storage area by
the following operations.
• Power supply turn ON
• Write to the cam storage area
• PLC READY signal [Y0] OFF to ON
• When specifying the cam open area with the cam
data operation function
• When executing the cam auto-generation function
