7.1 Global System Data Setting Operations
This section deals with basic operations that prepare definition screens for system setting
data, and discusses which definition screens are to be called out in the MotionSuite™
series machine controllers.
7.1.1 On-line Mode and Off-line Mode
The types of data files to be created and updated differ according to whether the unit is
in the on-line mode or off-line mode. In the on-line mode, the data is registered in the
PLC. This data is stored both in the PLC and on the hard drive during new file cre-
ation and update. In the off-line mode, the data is registered on the hard disk. This
data is stored only on the hard drive during new file creation and update. Data created
in the off-line mode must later be transferred to the PLC in the on-line mode. The
PLC data is not updated if transmission is not performed.
