GT10/GT30

1.2 GT10 Names and Functions of Parts

 

 

(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.

(7) Waterproof packing

This assures that the front panel is waterproof. One piece is provided as an accessory when the unit is shipped.

CAUTION

SRAM backup by the secondary battery

When the unit is shipped, the No. 1 operation mode setting switch is set to the “OFF” psosition, in order to prevent excessive discharging of the secondary battery. Before using the unit, turn on the No. 1 operation mode setting switch on the back of the main unit, to turn on the SRAM backup function of the secondary battery. For detailed information on the secondary battery, please see page 128, “What the Internal Secondary Battery Does”.
