Preface
Essential Safety Precautions
This manual includes procedures that must be followed to operate the GLC correctly and safely. Be sure to read this manual and any related materials thoroughly
to understand the correct operation and functions of the GLC unit.
Safety Symbols
Please pay attention to the following safety symbols and their meanings:
Indicates situations that will definitely
result in major machine damage, severe
DANGER
WARNING
bodily injury, or death if the instructions are
not followed.
Indicates situations that may result in major
machine damage, severe bodily injury, or
death if the instructions are not followed.
Indicates situations that may result in
CAUTION
damage to the machinery, or minor bodily
injury if the instructions are not followed.
DANGERS
When Designing your GLC System:
• Be sure to design your GLC control system so that, in the
event of a main power supply failure or a GLC accident, the
user system’s overall safety integrity will be maintained. If
this is not done, incorrect output signals or a GLC malfunction may cause an accident.
(1) Interlock and other circuits designed to interrupt or op-
pose normal machine movement (such as Emergency
Stop, General Protection, and forward and reverse rotation), as well as those designed to prevent machine damage (such as upper, lower, and traverse movement limit
positioning) should all be located outside of the GLC.
(2) When the GLC generates a “Watchdog Timer Error ,” GLC
operation will halt. Also, when Errors occur in Input/Output control areas that the GLC cannot detect, unexpected
movement may occur in those areas. Therefore, and to
prevent unsafe machine movement, create a “Failsafe Circuit” that is completely external to the GLC.
GLC2300 Series User Manual6
Preface
DANGERS
(3) If a problem arises with an external unit’s relay or transis-
tor , causing an output (coil) to remain either ON or OFF, a
major accident can occur . To prevent this, be sure to set
up external watchdog circuits that will monitor vital output signals.
• Design a circuit that will supply power to the GLC unit’s
I/O before starting up the GLC. If the GLC unit’s internal program enters RUN mode prior to the I/O unit’s load control
power turning ON, an incorrect output (signal) or malfunction
could cause an accident.
• Design a user program to ensure the safety of the user’ s sys-
tem in the event of a GLC display or control error , or either a
data transmission error or power failure between the GLC
and a connected unit — all of which can lead to an incorrect
output (signal) or malfunction, resulting in an accident.
• Do NOT make switches using the switches on the touch pan-
els which may cause operator injury and machine damage.
To prevent major accidents caused by an output remaining
either ON or OFF, set up circuits (such as limiters) that will
monitor vital output signals. To prevent accidents caused by
incorrect output or malfunction, design switches used by separate devices to perform important operations.
• Do NOT use GLC touch panel switches to perform operator
safety-related or important accident-prevention operations.
These operations should be performed by separate hardware
switches to prevent operator injury and machine damage.
• T o prevent any possibility of bodily injury or material damage,
design your system so that equipment will not malfunction
due to a communication fault between the GLC and its host
controller .
• Do NOT use the GLC as a warning device for critical warning
alarms that can cause serious operator injury, machine damage, or production stoppage. Use stand-alone hardware and/
or mechanical interlocks to design alarm indicators and their
control/activator units.
GLC2300 Series User Manual 7
Preface
DANGERS
• The GLC is not appropriate for use with aircraft control devices, medical life-support equipment, central trunk data transmission (communication) devices, or nuclear power control
devices, due to their inherent requirements of extremely high
levels of safety and reliability.
• When using the GLC with transportation vehicles (trains, cars,
and ships), disaster and crime prevention devices, various
types of safety equipment, and medical devices that are not
life-support related, use redundant and/or failsafe system
designs to ensure proper reliability and safety.
WARNINGS
• Unlike the GLC unit’s “Standby Mode,” after the GLC unit’ s
backlight burns out, the touch panel is still active. If the
operator fails to notice that the backlight is burned out and
touches the panel, a potentially dangerous machine
misoperation can occur. Your backlight is burned out if:
• your GLC is not set to “Standby Mode” and the screen
has gone blank
• your GLC is set to “Standby Mode,” but touching the
screen does not cause the display to reappear
To prevent accidental machine misoperation, Pro-face recommends that you use the GLC unit’s “
AFTER BACKLIGHT BURNOUT
detect a burnout and disable the touch screen.
Installation Warnings:

USE TOUCH PANEL
• High voltage runs through the GLC. T o prevent an electrical
shock, do NOT disassemble the GLC for any reason other
than to replace the backlight.
• Do NOT modify the GLC unit. Doing so may cause a fire or
an electrical shock.
• Do NOT use the GLC in an environment where flammable
gases are present, to prevent an explosion from occurring.
GLC2300 Series User Manual8
Preface
WARNINGS
Wiring Warnings:
• To prevent electrical shock or equipment damage, unplug
the GLC unit’s power cord from the power supply prior to
installing or wiring the GLC.
• After completing any GLC wiring work, be sure the termi-
nal block’s protective plastic cover is reattached. If this
cover is not reattached, an electrical shock could easily
occur .
• Do NOT use power levels with the GLC that are higher or
lower than the GLC unit’s specified power range. Doing so
may cause a fire, electrical shock, or GLC damage.
Operation and Maintenance Warnings:
• NEVER touch a live power terminal. Doing so could cause
an electrical shock or a machine malfunction.
• T o prevent an electrical shock, unplug the GLC unit’ s power
cord before either cleaning the GLC or attaching/detaching the power terminal attachment screws.
• When replacing the GLC unit’s backlight, be sure to un-
plug the unit’s power cord to prevent an electrical shock,
and wear safety gloves to prevent burns.
• The GLC uses a lithium battery to back up its internal clock
and to control memory data. If the battery is incorrectly replaced (reversed positive [+] and negative [-] ends), the battery may explode. Therefore, Pro-face recommends that you
contact your local GLC distributor for instructions before
replacing or changing the battery.
GLC2300 Series User Manual 9
Preface
CAUTIONS
Wiring Layout Cautions:
• To prevent a GLC unit malfunction due to excessive noise,
isolate all GLC input/output signal lines from all power wiring
or power cables via a separate wiring duct.
Installation Cautions:
• T o reduce the risk of incorrect input or output signals, be sure
that any data cables attached to the GLC unit’s connector
make full contact with the connector pins.
General Wiring Cautions:
• To prevent electrical shocks or malfunctions, be sure the
GL C unit’s FG (earth) wire is grounded as follows:
(1) maximum grounding resistance: 100
(2) minimum grounding wire diameter: 2 mm
ΩΩ
Ω
ΩΩ
2
• The cables connected to the GLC should be secured by cable
clamps to prevent weight or tension of the cables added to
the connectors or terminals.
• The GLC unit’s wiring should be checked to confirm that both
the operating voltage and wiring terminal locations are correct. If either the voltage or the wiring terminal location is
incorrect, it can cause a fire or accident.
• Be sure to secure all wiring terminal screws with the designated torque. Screws and terminals that become loose can
cause a short circuit, fire, or accident.
• Be sure that metal filings or wiring remnants do not fall inside
the GLC, since they can cause a fire, accident, or malfunction.
GLC Operation and Maintenance Cautions:
• Be sure to read the GLC unit’s manual and online help information carefully before performing program changes, entering forced output, or using the RUN, STOP, or PAUSE commands while the GLC is operating. Mistakes made when
using these items can cause machine accidents or damage.
GLC2300 Series User Manual10
Preface
CAUTIONS
• Be sure the electricity is turned OFF before attaching or
detaching an I/O unit. If the electricity is ON when an I/O
unit is attached or detached, damage or malfunction to the
I/O unit may occur.
• The liquid crystal panel contains a powerful irritant. If, for
any reason, the panel is damaged and this liquid enters
your eyes, flush your eyes for 15 minutes with running water
and contact a physician immediately.
• Prior to inserting or removing a CF Card, and to prevent
damage to or loss of the CF Card’s internal data, turn the
GLC unit’s CF Card ACCESS switch OFF, and make sure
that the ACCESS lamp is not lit.
• While a CF Card is being accessed, NEVER:
• turn OFF the GLC
• reset the GLC
• insert a CF Card
• remove a CF Card
Prior to performing these operations, create and use a spe-
cial GLC application screen that will prevent access to the
CF Card.
Refer to the GP-PRO/PB III for Windows Tag Reference Manual
(included in the GP-PRO/PB III C-Package).
GLC Unit Disposal Cautions:
• The GLC unit should be disposed of in a manner appropri-
ate to, and in accordance with, the user country’s industrial machinery disposal standards.
GLC2300 Series User Manual 11
Preface
General Safety Precautions
• Do NOT strike the touch panel with a hard or pointed object, or press
on the touch panel with too much force, since it may damage the touch
panel or the display.
• Do NOT install the GLC where the ambient temperature can exceed the
allowed range. Doing so may cause the GLC to malfunction or shorten
its operation life.
• Do NOT restrict or limit the GLC unit’s naturally-occurring, rear-face
ventilation, and do NOT store or use the GLC in overheated areas.
• Do NOT store or use the GLC unit in areas where large, sudden tem-
perature changes can occur. These changes can cause condensation to
form inside the unit, which can cause possible unit malfunctions.
• Do NOT allow water, liquids, metals, or charged particles to enter inside
the GLC unit’s outer casing, since they can cause either a GLC malfunction or an electrical shock. The allowable pollution degree is 2.
• Do NOT store or use the GLC in direct sunlight, or in excessively dusty
or dirty environments.
• Do NOT store or use the GLC in an environment where shaking or ex-
cessive vibration can occur.
• Do NOT store or use the GLC where chemicals (such as organic sol-
vents and acids) can evaporate, or in environments where chemicals
and acids are present in the air.
Corrosive chemicals: acids, alkalines, liquids containing salt
Flammable chemicals: organic solvents
• Do NOT use paint thinner or organic solvents to clean the GLC.
• Do NOT store or operate the LCD (Liquid Crystal Display) in areas that
receive direct sunlight, since the sun’s ultraviolet (UV) rays may cause
the quality of the LCD to deteriorate.
• Storing this unit in areas at temperatures that are lower than is recom-
mended in this manual’s specifications may cause the LCD panel’s liquid to congeal, which may damage the panel. Conversely, if the storage
area’s temperature becomes higher than the allowed level, the LCD
panel’ s liquid will become isotropic, causing irreversible damage to the
LCD. Therefore, be sure to store the panel only in areas where temperatures are within the ranges specified in this manual.
• Due to the possibility of unexpected accidents, be sure to back up the
GLC unit’s screen data/logic program regularly.

About the GLC Unit’s Display Panel
• The data that is currently displayed on the GLC unit’s screen, the screen’s
brightness, and the GLC unit’s voltage
sity of Contouring — wavelike pattern that is created when some parts
of the screen are brighter than others.
• The minute, dark and light grid-points on the display panel’s surface are
part of the GLC unit’s design and are not defects.
• Extended shadows, or “crosstalk,” may appear on the sides of screen
images. This is normal for an LCD panel.
• Sometimes the display area may look as if the display colors have
changed.
• Displaying a single image for long periods of time can cause an afterimage to remain when the screen display is changed.
To prevent this effect:
Use the GLC unit’s “Standby Mode,” which automatically turns the
screen OFF when no input is entered within a specified period of
time.
This is a common attribute of LCDs and is not a defect.

See 6.3.1 – “System Setup.”
• Write “FFFFh” to the System Data Area’s “Screen Display Off” address
to turn the screen display OFF when the following actions are not performed within the user-specified period of time.
• Change Screen
• T ouch Screen
• Alarm Display
Do NOT display any single screen for a long period of time. Try to
change the screen display periodically.
1. The backlight’s brightness may vary or its lighting may be delayed if the voltage
provided is low — even if still within the range of rated voltage listed in the specifications. When the voltage is high, the backlight’s lifetime may be shortened. As a rule,
voltage should be within five percent (5%) of rated voltage.
2. The following addresses assume all System Data Area settings are entered. If they are
not all entered, the correct word address may be different, since the following addresses are relative, not fixed, addresses.
With the Direct Access Method — use System Data Area word address +9
With the Memory Link Method — use System Data Area word address +12

1.4 GLC2300 Series Overview
The GLC-2300-LG41-24V and GLC2300-TC41-24V units are equipped with a
variety of new and useful features, such as an Ethernet, CF Card and Expansion
Serial Interfaces as standard equipment. The new GLC features are as follows:
Ethernet Feature
Your GLC2300 Series unit includes an Ethernet 10BASE-T connector as standard
equipment. In addition to sending screen data to the GLC, you can use this feature
to set up the GLC, even if you are using the unit for the first time*1. Also, Proface’ s separately-sold Pro-Server software can read out data collected in the GLC
to a central PC server via an Ethernet LAN network. And with a variety of software applications, you can process the data for production information management.
CF Card Feature
This interface allows you to use the CF Card instead of the optional Memory
Loader II to store GLC setup*1 and screen data, and then transfer it to the GLC.
You can also
read and write data to your existing (optional) multi-unit’s CF Card, since the
GLC unit’s card is the same type. The CF Card can also be used to store and
transfer recipe, logging, alarm history, and .bmp data files. The GLC can read
these files from the CF Card, or use the CF Card to store data read out from the
host (PLC).
Expansion Serial Interface
This interface allows you to connect a variety of equipment, including a bar-code
reader, a 2-D code reader or an I/O device.
Flex Network Communication I/F
A high speed remote (6Mbps/12Mbps) interface capable of connecting a maximum of 1008 I/Os.
2-Port Feature
The GLC unit’s built-in 2-Port feature allows you to enjoy 2-Port operation with a
Mitsubishi brand PLC, without using the optional 2-Port Adapter II unit.
Backlight Burnout Detection Feature
When the GLC unit’s backlight burns out, it will be automatically detected. The
GLC unit’s “Status LED” will alert you that the backlight is burned out so that
you can disable GLC Touch Panel Operation and prevent a possible GLC operation mistake.
Please read the following sections for detailed information about each feature.
1. Setting up the GLC means downloading the required system and protocol programs
from the GLC screen creation software to the GLC.
GLC2300 Series User Manual 1–9
Chapter 1 – Introduction
1.4.1 Ethernet Connectivity
The GLC2300 Series units can be connected to a LAN or an Ethernet compatible
PLC. The GLC2300 Series units also support the 2-way function.
This feature allows you to setup a GLC and to also perform screen data transfer.
You can even set up a completely new GLC via an Ethernet network.
For details about setting up the GLC via an Ethernet network, refer
to the GP-PRO/PB III for Windows Operation Manual (included in
the GP-PRO/PB III C-Package).

1.4.2 CF Card
Chapter 1 – Introduction
The new GLC2300 series unit allows you to use a CF Card. You can set up the GLC
or send screen data by saving backup data (all data necessary for GLC operation) in
the CF Card using the GLC unit’ s CF Memory Loader Tool feature. As with the Multi
Unit, the GLC2300 series unit includes all the following features:
• Read filing data from CF Card
• Write logging data to CF Card
• Read image data or sound data from CF Card
• Write Graph data or Alarm data to CF Card
• Back up screen data to CF Card
For details about creating/saving backup data (i.e., all necessary data
for GLC operation) and sending GLC data, refer to the
GP-PRO/PB III for Windows Operation Manual (included in the
GP-PRO/PB III C-Package). For details about the CF Memory
Loader Tool’s data upload and download, see 4.3 – “CF Memory
Loader Tool.”
When using the CF Memory Loader Tool, Digital’s GP077-CF20 (16MB)/
GP077-CF30 (32MB) Memory Card is required.
*1
Send GLC Screen Data to a CF Card, then to Other GLCs
The CF Card allows you to set up multiple GLCs using a single GLC unit’s data.
Copy your GLC data and the CF Memory Loader Tool to your GLC unit’s CF
Card, then insert that CF Card in another GLC and transfer that data using the CF
Memory Loader Tool.

1. The setup is the sending of System and Protocol programs to the GLC via the screen
creation software, which allows you to use the GLC unit in the desired environment.
GLC2300 Series User Manual 1–11
Chapter 1 – Introduction
Send GLC Screen Data to a GLC, then to the CF Card
You can also use the GLC as a CF Card drive for your PC, by sending data from
your PC directly to your GLC unit’s CF Card. Connect your PC and the GLC
using the data transfer cable, and send your backup data and the CF Memory
Loader Tool to the CF Card installed in the GLC.
Send data using the GP-PRO/PB III for Windows’ Transfer feature
Transferring screen and system data to a GLC takes approximately thirteen minutes (approximately 6.5 MB) at a transmission speed of 115.2 kbps.
Send Data from a GLC to a CF Card, then to Another GLC
The CF Card allows you to use backup data saved in a GLC for setting up another
GLC. First, upload (transfer) your GLC unit’s backup data to your CF Card. Next,
remove the CF Card, insert it in a different GLC and download (transfer) the CF
Card’s data to that GLC. Be sure that the CF Memory Loader Tool is saved on the
CF Card prior to using this method.

1.4.3 Expansion Serial Interface
The Expansion Serial Interface allows you to connect a bar-code reader, a 2-D
code reader, or other type of I/O device. It enables the input/output of large volumes of data which cannot be handled with a conventional bar code reader interface.
Also, connecting an I/O device requires the creation of a data transfer protocol
(via the D-Script feature).
Refer to the GP-PRO/PB III for Windows Operation Manual (included in the GP-PRO/PB III C-Package).

1.4.4 Flex Network Communication Interface
The following information explains how to connect the GLC to a Flex Network
Communication I/F and I/O Unit.
When connecting the I/O unit, 2 lines are available — CH1 and CH2. Each channel outputs the same data and either can be used for data transmission.
The maximum number of connectable units, when using a single channel, is 31,
and when using a second channel, the number increases by 32 to a total of 63.
The Flex Network uses high-speed data-transfer technology, and if a
cable that is not recommended in this document is used for data transfer, network data-transfer performance cannot be guaranteed. Therefore, use only the cable(s) recommended here.
