Pro face GP370 Complete Guide

Input voltage: DC 20.4~27.6 V (rated 24 VDC), power consumption less than 20 W (typical 10 W).

Terminal: The power terminal block is located on the back of the GP and uses a circular terminal (JST V2-MS3 is recommended) with a maximum cross-sectional area of 2 mm ² for the wire.

Grounding: The FG terminal must be grounded, and dedicated grounding (grounding resistance<100 Ω) should be preferred; If dedicated use is not possible, public grounding can be used. The cross-sectional area of the grounding wire should be greater than 2 mm ² and as short as possible. Attention: If the equipment works abnormally after grounding, try disconnecting the FG terminal (floating).

Wiring steps: Power off → Remove terminal cover → Loosen three screws → Insert ring terminal → Tighten screws (torque 0.5~0.6 N · m) → Replace cover.

2.3 Signal line isolation

The input/output signal line must be routed separately from the power control cable. If unavoidable, shielded cables should be used and the shielding layer should be connected to the ground of the GP rack.

2.4 Precautions for using tool connectors

Before plugging or unplugging the download cable or barcode reader, be sure to turn off the GP power.

If the barcode reader uses an independent power supply, the barcode reader power should be turned on first, and then the GP power should be turned on; When shutting down, turn off GP first, and then turn off the barcode reader.

Chapter 3: Offline Mode and System Initialization - Core Operations for First Power On

GP370 has no screen data when it leaves the factory, and for the first use, system files and screen data must be transferred through screen editing software. Off line mode is the entry point for initialization settings, self diagnosis, and image transmission.

3.1 Methods for entering offline mode

Method 1 (enter when powered on): Within 10 seconds after turning on the power, touch the top left corner of the screen.

Method 2 (Force Reset): In either running or offline mode, simultaneously press and hold the bottom right, top right, and bottom left corners of the screen to enter the Force Reset screen, and then press the "OFFLINE" button.

If a password has been set in the system settings (range 0~9999, default 0 is no password), the password needs to be entered before entering offline mode.

3.2 Main menu functions

The offline mode main menu contains four options:

Initialize: Set various parameters required for GP operation (communication, PLC, system environment, etc.).

Transfer Screen Data: Transfer screen data between PC and other devices.

SELF-DIagnoSIS: Detect GP system and interface faults.

RUN: Start normal operation and communicate with PLC.

3.3 Initialization Menu Explanation

The initialization menu is divided into 1:1 connection (one GP connected to one PLC) and n:1 multi link connection (multiple GPs sharing one PLC). The following are the key submenus:

3.3.1 System Environment Setup

Standby mode time (0-255 minutes): Screen saver function, automatically turns off display after no operation exceeds the set time. 0 indicates constant brightness.

Start time (0-255 seconds): The delay in entering the running mode after GP is powered on, used to wait for the PLC to start first.

Touch buzzer sound: on/off.

Buzzer terminal output: whether the buzzer signal is output from the AUX I/F (external buzzer).

Password setting: Prevent unauthorized access to offline mode.

Screen number data type: Select BIN (screen numbers 1~8999) or BCD (screen numbers 1~1999).

3.3.2 System Area Setup

Used to allocate a data area in PLC for GP to read and write status information (such as current screen number, error status, clock data, switching screen number, display switch, etc.). The size of the system area is automatically calculated based on the selected items. The starting address of the system area is specified by the PLC side (such as D00200), and each project is assigned an address according to a fixed offset.

3.3.3 Global Window Setup

GP can display both a global window (applicable to all screens) and two local windows simultaneously. You can set whether to use global windows, window registration numbers, and addressing methods for location (direct/indirect).

3.3.4 CHARACTER STRING DATA SETUP

The byte order of storage strings varies among different PLCs. Set according to PLC model:

Storage order of data devices (starting data storage/ending data storage)

Byte order within words (LH/HL)

Double character order (LH/HL)

For example, Omron PLCs typically choose mode 4 or 5, while Mitsubishi PLCs choose mode 1 or 2. Setting errors can result in garbled characters being displayed.

3.4 Communication parameter settings (SET UP I/O)

3.4.1 SIO Settings

Communication speed: 2400-38400 bps, must be consistent with PLC.

Data length/stop bit: 7 or 8 bits of data, 1 or 2 bits of stop bit.

Parity check: none, odd, even.

Flow control: X-CNTRL or ER-CNTRL.

Communication format: RS-232C, RS-422 4-wire, RS-422 2-wire. When using Memory Link, choose 4 wires.

3.4.2 I/O Settings

Touch operation mode: single point or two-point input.

Force reset: enable/disable. After activation, you can enter the forced reset screen by touching three points simultaneously.
