(2) Front panel protective sheet
This protects the touch panel and keeps it clean. One sheet is attached to the panel when
the unit is shipped.
(3) Power supply terminal
The operation power supply is connected here.
(4) COM. port (PLC/external device connection port)
A device such as a PLC, a higher–order computer, or a microcomputer board can be
connected to this RS232C port. (One communication connector is provided as an
accessory when the unit is shipped.)
(5) TOOL port (GTWIN connection port)
This port is used to connect a personal computer in which the screen creation tool
GTWIN has been installed, using a dedicated cable (AFC8513).
(6) Operation mode setting switches
With the GT10, screen data and configuration settings data are stored in an internal
F–ROM, so no battery backup is needed. However, data such as clock data and the Hold
PLC Device Data is stored in the internal SRAM, and is backed up by the internal
secondary battery, which is charged when the power supply is turned on.
The operation mode setting switches control the ON/OFF settings for the secondary
battery backup function, the ability to shift to the system menu, and other functions.

the SRAM backup function of the secondary battery. For detailed
