Congratulations on purchasing Digital’s Pro-face GP-377R Series Graphic
Control Panels (hereafter referred to as "the GP").
This GP unit, with its expanded functionality and improved overall perfor-
mance, is an upgrade of Digital's GP70 series panels. Also, instead of using
the optional 2-Port Adapter, the Mitsubishi Electric Corporation's GPP
software package and the GP's rear face tool connector can now be used to
provide 2-Port feature communication.
Please read this manual carefully as it explains, step by step, how to use the
GP correctly and safely.
Also, in this manual's examples, the Mitsubishi MELSEC-AnA Series PLC
is used whenever possible, connected in a one-to-one relationship with a GP.

GP-377R Series Users Manual
Preface
This manual includes procedures that must be followed to operate the GP
correctly and safely. Be sure to read this manual and any related materials
thoroughly to understand the correct operation and functions of this unit.
Usage of Icons
To allow you to use the GP correctly, throughout this manual, the following
icons are provided next to operations requiring special attention. The opera-
tions described with these icons contain essential safety information. The
following is an example of these icons and their meanings:
Indicates situations where severe bodily
injury, death or major equipment damage
can occur.
Indicates situations where slight bodily
injury or machine damage can occur.
Essential Safety Precautions
Design Precautions
• Do not create switches used to control machine safety operation, such as
an emergency stop switch, as a GP touch screen icon. Be sure to install
these switches as separate hardware switches otherwise bodily injury or
damage can occur.
• Please design your system so that the machine will not malfunction due to
a communication fault between the GP and its host controller. This is to
prevent any possibility of personal injury or material damage.
Installation Precautions
• High voltage runs through the GP. Except for replacing the backlight,
never disassemble the GP, otherwise an electric shock can occur.
• Do not modify the GP unit. Doing so may cause a fire or an electric
shock.
• Do not use the GP in an environment where flammable gasses are present,
since operating the GP may cause an explosion.
Wiring Precautions
• Prior to installing the GP or when connecting any cables or lines to it, be
sure to confirm that the GP's power cord is not connected to the main
power to avoid the possibility of an electric shock.
• Do not use power beyond the GP's specified voltage range. Doing so may
cause a fire or an electric shock.
Start-up and Maintenance Precautions
• The GP uses a lithium battery for backing up its internal clock data. If the
battery is incorrectly replaced, the battery may explode. To prevent this,
please do not replace the battery yourself. When the battery needs to be
replaced, please contact your local GP distributor.

Preface
Installation Precautions
• Be sure to use the attachment screws given (included with the GP) to attach an
expansion unit to the GP. If the expansion unit is not attached correctly, incorrect
GP operation may be caused, or the expansion unit may malfunction or fall off the
GP unit.
• Be sure to securely connect all cable connectors to the GP. A loose connection may
cause incorrect input or output.
Wiring Precautions
• Ground the GP's FG line separately from other units’ FG lines. Putting these FG
lines too close may cause an electric shock or unit malfunction. Be sure to use a
grounding resistance of 100Ωor less and a 2mm2or thicker wire, or your country’s
applicable standard.
• When wiring the GP, be sure that the rated voltage and terminal layout are within the
designated range. If the voltage supplied differs from the rated voltage, or incorrect
wiring or grounding is performed, it may cause a fire or unit malfunction.
• Use only the designated torque to tighten the GP's terminal block screws. If these
screws are not tightened firmly, it may cause a short-circuit, fire, or GP malfunc-
tion.
• Be careful that metal filings and wiring debris do not fall inside the GP, since they
can cause a fire, GP malfunction, or incorrect operation.
GP Start-up and Maintenance Precautions
• Prior to attaching or removing an expansion unit, be sure that the GP’s power cord is
not connected. If the attachment or removal of an expansion unit is performed
while the GP's power cord is connected, an expansion unit or a GP malfunction
may occur.
• The liquid crystal panel contains a powerful irritant and if for any reason the panel is
damaged and this liquid contacts any part of your body, be sure to wash that area with
running water for 15 minutes. If any of this liquid enters your eye, flush your eye for
15 minutes with running water and contact a physician.
GP Disposal Precautions
• When this unit is disposed of, it should be processed according to your country's
regulations for similar types of industrial waste.
■ ■
■ ■
■ To Prevent Damage to the GP
• Never strike the touch panel with a hard or heavy object, or push on the
touch panel with too much force since it may damage the unit.
• If the GP is used in an environment with temperatures and humidity in
excess of the allowed range, the GP may malfunction and/or its useful life
may be shortened.
• Avoid restricting the GP’s naturally occurring ventilation, or storing or using
the GP in an environment that is too hot.
• Do not use this unit in areas where large, sudden temperature changes can
occur thereby causing condensation to form inside the unit. This can cause
the unit to malfunction.
Caution

vii
GP-377R Series Users Manual
Preface
• Do not allow water, liquids, metal particles, or charged particles to enter
inside the GP’s chassis, since they can cause either a GP malfunction or an
electrical shock.
• Avoid using or storing the GP in direct sunlight, or in excessively dusty or
dirty environments.
• Because the GP is a precision instrument, do not store or use the GP where
a large shocks or excessive vibration can occur.
• Do not store or use the GP where chemicals (such as organic solvents, etc.) and
acids can evaporate, or where chemicals and acids are present in the air.
• Do not use paint thinner or organic solvents to clean the GP.
• Do not store or operate the LCD display in areas receiving direct sunlight,
since the sun’s strong UV rays may cause the LCD display’s quality to
deteriorate.
• Storing this unit in areas at a temperature lower than is recommended in this
manual’s specifications may cause the LCD display’s liquid to congeal, which
may damage the panel. Conversely, if the storage area’s temperature becomes
higher than the allowed level, the LCD’s liquid will become isotropic, which is
irreversible. To avoid problems like these, be sure to store the panel only in
areas where temperatures are within those specified in this manual.
Due to the danger of unforeseen accidents, be sure to back up
the GP’s screen data regularly.
About the GP's Display Panel
• The Display Panel contents, the power voltage and brightness affect the
intensity of Contouring*1. (i.e, when some parts of the screen are brighter
than others, creating a wavelike pattern)
• There are minute grid-points (dark and light) on the Display Panel's
surface. This is part of the GP's design and not a defect.
• Shadows may appear at the top of the LCD. This is normal for an LCD
display.
• Sometimes the display area may look as if the display colors have
changed. This is a common attribute of LCD's and is not a defect.
• Displaying a single image for long periods can cause an afterimage to
remain when the display is changed to another screen.
To prevent this effect:
Set the unit to "Stand-by Mode", which automatically turns the screen
OFF when there is no input for a specified period of time.
5.3.1 System Setup
• When a single screen will be constantly displayed, write "FFFFh" to
the System Data area's [Screen Display OFF] area*2, which will turn
the screen display off.
Do not display any single screen for a long period of time. Try to
always change the screen display periodically.
*1 Even if the operating voltage is within the specified range, if it becomes too low, the
backlight may create contouring.
*2 When the Direct Access method is used, the corresponding system data area word
address is +9. With the Memory Link method is used, it is address 12. (Assuming the
System Data Area's settings are all entered)

)*Internal 2-Port Feature Usage Notes
•To use the Internal 2-Port feature, you will need to adjust your GP’s settings.
For information about these settings, refer to GP-PRO/PBIII
for Windows PLC Connection Manual (included with the GP Screen creation
software)
•This feature can be used only while the GP is in ONLINE mode.
•Since the internal 2-Port feature uses the GP’s single tool connector, you will
not be able to use equipment which requires the tool connector (i.e. a Barcode
Reader, Optional Items, etc.)
•If you transfer screen data while the GP is in ONLINE mode, the screen
will not change to the data transfer screen automatically. Thus, you will
need to change the screen manually to the OFFLINE mode's [Main Menu/
Transfer] screen. 4.5 Transferring Screen Data
•Peripheral equipment which cannot be connected to the GP's tool connector
(such as a Programming Console) is not compatible with the GP's Internal 2-
Port feature. To use this type of equipment, you will need to use the external 2-
Port Adapter II.
