The following topics are some of the more likely problems that may be encountered during
the installation and operation of your C-more touch panel. We have made some suggestions
on what to check in order to correct the problem. Please start with the troubleshooting flow
chart that covers the more common problems encountered by other users.
Common Problems
The troubleshooting flow chart shown on the following page is based on the more common
problems fielded by our technical support team. If you are having problems, please start with
the flow chart, follow the suggestions listed, and if you still need help, call our tech support team
@ 770-844-4200. In addition to having ready the information suggested in the flow chart,
please have the following available:
1) C-more touch panel part number including serial number with date code. See page 1-5 in
this hardware user manual for an explanation of the part number, serial number, and date
code breakdown. Why is this information important? The various sizes of the touch panel use
different processors and memory sizes, and therefore can have different types of problems
within the particular panel size.
2) Programming software version that you are currently using. For example: Version 2.20
(Please note that software versions 2.0.7.35 and before will also have a build number such as
2.0 Build 07.35). Having the software version number will allow our tech support team
member to assess whether there are similar problems that have been reported when using the
same version of the software. The programming software version can be found by clicking on
“About C-more Programming Software...” selection under the Help pull down menu in the
software. Also, it is always a good practice to visit the Software/Firmware Downloads area
under the Tech Support section of the AutomationDirect website and check to see if you are
using the latest version of the programming software. If you aren’t using the latest software
version, we suggest that you upgrade to see if this resolves your problem.
Note: The “About C-more Programming Software...” dialog box will show a Firmware version on the newer
releases of the programming software. This is the current firmware version that is included with the
programming software and does not reflect what firmware is actually loaded on your C-more touch panel.
See the following for details on how to check the firmware version.
3) Firmware version of the C-more touch panel. For example: 2.0 Build 07.32 or 2.0.07.32. The
firmware version can be checked by using the System Setup Screens, going to the
Information menu under the Main Menu, and looking under the General tab for Firmware:
-Runtime. The firmware version can also be checked by using the programming software,
while connected to the panel, and clicking on the Panel Information selection under the
Panel pull down menu. As with the programming software version, it is important for our
tech support associates to know which firmware version you are using so they can check on
any known problems. As with the programming software, we strongly suggest that the
firmware be updated to the latest version. Check for the latest version and downlaod from the
Software/Firmware Downloads area of the AutomationDirect website.
It is also helpful to have a copy of your project file for our tech support associates to use in
troubleshooting a problem, so please be prepared to forward a copy of your project if it is
requested.

1.) Check the status indicators on the rear of the panel to see if the Power LED (Green)
indicator is on. Reference the diagram shown below. If the Power LED (Green) indicator is
on and the panel was observed showing “Initializing...” during power up, but the display is
now blank, go to the next troubleshooting tip, Display is Blank.
2.) If the Power LED (Green) indicator is off and the panel is being powered with a 24 VDC
power source, use a voltmeter to check the incoming DC voltage level. The DC voltage level
should be in the range of 20.4 to 28.8 VDC. If the incoming DC voltage is zero, check any
fusing that may be in the circuit. If the fuse is open, determine cause and replace. If the DC
voltage level is out of range, the DC power source needs to be corrected or replaced.
3.) If the Power LED (Green) indicator is off and the panel is being powered with an AC/DC
Power Adapter, EA-AC, use a voltmeter to check the incoming AC power. The AC voltage
to the AC/DC Power Adapter should be in the range of 100 to 240 VAC, 50/60 Hertz. If
the incoming AC voltage is zero, check any fusing that may be in the circuit. If the fuse is
open, determine cause and replace. If proper AC voltage is present on the AC/DC Power
Adapter, but the Power LED (Green) indicator is off, replace the AC/DC Power Adapter,
EA-AC.

• The Power LED (Green) should be on. If not, check the incoming power as explained in the “Touch
Panel does not Power Up” section.
• Make sure the CPU status LED (Green, Orange, Red) is a steady Green.
• A blinking Orange colored CPU status LED indicates a failed LCD display backlight. The backlights
are user replaceable on the 8”, 10”, 12” and 15” C-more touch panels with LCD display backlights.
LED display backlights are not user replaceable. See Chapter 9: Replacement Parts for additional
information on replacement backlights.
• If the CPU status LED is blinking Green, then the supply voltage is below 19.2 VDC, or below 100
VAC when using the optional C-more AC/DC Power Adapter, EA-AC. The backlight will turn off
immediately to extend the power retention period. The panel will continue to run and the LCD
display will be slightly visible. This may be seen as the display being dim, so it is advisable to check
the incoming voltage. The panel does not turn off until the DC voltage drops below 5 VDC or below
58 VAC when using the AC/DC Power Adapter, EA-AC.
• A blinking Red CPU status LED indicates that the operating system could not be found. Reload the
firmware to the touch panel. If this does not resolve the problem, contact the AutomationDirect
returns department @ 1-800-633-0405 to make arrangements for returning the unit for repair.

3.) There is always the remote possibility that a project has been transferred to the touch panel
that includes a screen that uses a black background and has no objects placed on the screen.
To check for this possibility, access the Main Menu of the touch panel System Setup Screens
by pressing the extreme upper left corner of the panel display area for three (3) seconds as
shown below. If the System Setup Screen’s Main Menu is displayed, then most likely an
empty black background screen is being displayed.

Display is Dim
1.) Check either the contrast or brightness setting found under the System Setup Screens. Keep
in mind that the STN type display models can have the contrast adjusted. The TFT type
display models can have the brightness adjusted. See Chapter 5: System Setup Screens for
additional information.
2.) Backlights will slowly lose some luminance causing the display to slightly dim. The
backlight average lifetime is rated at 50,000 hours and is defined as the average usage time
it takes before the brightness becomes 50% of the initial brightness. The lifetime of the
backlight depends on the ambient temperature; the lifetime decreases in low or high
temperatures. To improve the backlight life, use the Start Screen Saver function that is
available in the C-more Programming Software in the Panel Manager dialog box. The
backlights are user replaceable on the 8”, 10”, 12” and 15” C-more touch panels with
LCD display backlights. LED display backlights are not user replaceable. See Chapter 9:
Replacement Parts for additional information on the replacement backlights.

• The Screen Saver will be turned off and the panel screen will display:
– If a PLC Address is configured to control the Screen Saver and changes from On to Off.
– When the panel touchscreen is touched.
– When the screen is clicked by Remote.
– When the Alarm Event of the Event Manager occurs. (Only when the Display setting of the
Alarm Event is checked).
– When there is a screen change by the PLC.
– When an Error such as a Communication Error occurs.
3.) Another condition that may make the display appear dim is to view the touch panel in direct
sunlight or in a location where direct light is reflected onto the display. The C-more touch
panel displays have Display Brightness ratings of 150 to 300 cd/m2 (NITS), depending on
the particular model. The higher the cd/m2 (NITS) rating, the more visible the display will
be under bright lighting conditions.
No User Program
NO USER PROGRAM
If the touch screen is displaying the message “No User Program” after it has powered up, then
either:
– the built-in Flash memory does not contain a recognized project, or
– a CompactFlash memory card is plugged into the CF1 slot and there is no project on the
CompactFlash memory card. Turn the power off, remove the CompactFlash memory card and turn
the power back on.
Keep in mind that on power up, the touch panel will either copy the project from its internal
Flash memory to its internal SDRAM memory and run the project, or if a CompactFlash
memory card is plugged into the CF1 slot, then any project contained on the CF memory card
will be copied to the panel’s internal SDRAM memory and be run. In other words, the memory
of a CompactFlash card on CF1 will override the panel’s internal Flash memory on power up
or reboot, even if the CompactFlash memory card does not contain a project.

The C-more touch panel is programmed using the C-more Programming Software,
EA-PGMSW. The developed project is transferred from the PC to the touch panel by either a
USB or an Ethernet connection between the two. (Ethernet available on full feature units only.)
If using USB, then a USB type AB programming cable, such as p/n USB-CBL-AB15, should
be used to make a connection between the panel’s USB Port, Type B and a USB port on the
PC. The C-more Programming Software will install a USB driver on the PC during the
software installation.

When transferring a project to the panel using the Send Project to Panel function, if the USB
radio button in the Step 3 - Project Transfer dialog box, is DIMLY green, then although the PC
recognizes the panel, there is interference in the communication. If a PLC is connected to the
serial port of the panel, try disconnecting it. If this corrects the problem, then check your
grounding for the PLC and the panel.
Check the USB driver using Windows Device Manager:
With the C-more panel connected to the PC, on the PC, open Control Panel--> System
-->Hardware tab --> Device manager. Next expand "Universal Serial Bus controllers".
The C-more driver is named C-more HMI as shown below:
If the C-more programming software Communication Config dialog USB indicator is red, and
the driver does not appear in Device Manager,
1) Unplug both end of the cable and replug them in.
2) If that does not establish communication, plug into a different USB port on the PC.
3) If there are any USB hubs or other devices being used, temporarily eliminate them to see if this
solves the problem.
4) Reinstall the C-more HMI USB driver.

Use the C-more programming software to check the status of the Ethernet communications.
From the Navigation window, select the Panel tab. At the bottom of the Panel tab is the
Communication Config dialog box. Select the Browse button. If the connection is working the
panel will be listed in the online link list. Select the panel and then select OK. If the Ethernet
communications to the panel is working, then the Ethernet radio button should be checked and
there should be a “green” indicator next to the Ethernet selection. There should also be an IP
Address shown in the browse box below the Ethernet selection. If the Ethernet radio button is
“red”, then you will need to check your Ethernet cables and connections or Browse for the
panel.

Chapter 8: Troubleshooting
No Communications between Panel and PC (Personal Computer) (cont’d)
There can also be a conflict with another Ethernet connection that may be using the same IP
Address. You may want to check the setup both in the touch panel and also in your PC. As a
starting point, it is best to start with an assigned IP Address and Subnet mask, mainly to
eliminate IP addressing conflicts. Use the C-more programming software and open the Touch
Panel Network dialog box under the Main Menu’s Setup drop down menu. Click on the
Ethernet Port tab to display the dialog box used to set up the touch panel’s Ethernet port.
Another cause of an Ethernet communications problem that may be encountered, is the touch
panel doesn’t show up in the node list, which can be caused by the PC having a firewall.
The figure below shows the Touch Panel Network dialog box with the Ethernet port tab
opened. The Save settings to Project check box is checked and we are using the Use the
following IP Address selection by checking its radio button. The subnet (192.168.X.X) and
the subnet mask (255.255.0.0) must be the same for both the panel and the PC. See the
C-more programming software on-line help for additional details regarding the Touch Panel
Network.
In the example shown here, the
subnet is 192.168.X.X, the
subnet mask is 255.255.0.0,
and both need to be the same
for all the Ethernet devices
connected together.
The IP Address assigned to the touch panel can also
be checked or edited by using the system setup
screens built into the touch panel. See Chapter 5:
System Setup Screens for additional information.
The figure below shows a different example of the
panel’s System Setup Screens’ Ethernet Port dialog
box for configuring the Ethernet port. Again, make
sure the subnet (172.22.X.X) and subnet mask
(255.255.0.0) is the same for both the panel and the
PC.

Check the IP Address setting of the PC by opening the Windows operating system’s Control
Panel and then selecting the Network Connections utility. Click on Properties, scroll down to
Internet Protocol (TCP/IP) and click Properties. The Internet Protocol (TCP/IP) Properties
dialog box will open. Again, make sure the Subnet Mask is set the same for both the panel and
the PC and also make sure that the IP Addresses do not conflict.
Note: If a DHCP Server is being used to obtain the
IP Address for the PC, there are ways to identify the
IP Address. For example, if using Windows XP,
open a Command Prompt (Run > CMD) and type
IPCONFIG /ALL. A list of all Ethernet assignments
for the PC will be shown.

The communications between the C-more touch panel and designated PLC or controlling
device can be accomplished by either a serial connection to the panel’s 15-pin PLC
Communications Port or by an Ethernet connection to the panel’s 10/100 Base-T Ethernet
Port. (Ethernet available on full feature units only.)
1.) If the touch panel and PLC are connected serially and the communications have seemed to
stop working, then first check the TxD and RxD status indicators on the rear of the panel
for activity.

If a PC running the C-more programming software is connected to the Ethernet network that
is also connected to both the touch panel and PLC, then certain functions in the software, such
as the Main Menu’s Setup drop down selection for Panel Manager or Touch Panel Network
and the Main Menu’s Panel drop down selection for Panel Information, can be used to help
troubleshoot problems with the touch panel’s communications and operation. See the C-more
programming software’s on-line help for additional information.
IP Address in System Setup Screens displays 0.0.0.0
Note: If entering an IP Address for the C-more touch panel using the System Setup Screens, and the IP
Address keeps displaying 0.0.0.0, even after entering an IP address, the panel is not functionally connected
to an active network. Either the cable, hub, or switch is bad. The entered IP Address is stored in the panel’s
memory, but won’t show up until a good connection is established. Keep in mind that if in the C-more
programming software’s Touch Panel Network dialog box, under the Ethernet Port tab, you have checked the
Save settings to Project check box and have entered an IP Address of 0.0.0.0, then anytime the project is
transferred to the panel, the panel’s IP Address will be overwritten with the entered address.

Difficulty Connecting to the Panel over the Internet (Web server and Remote
Access features)
1) Refer to the software help file topics Touch Panel Network and Remote Access Setup for
information on configuring the Remote Access accounts, the Web Server Function and the
panel IP Attributes.
2) In the Ethernet Port tab if DHCP is selected for assigning the IP address, verify the currect
address of the panel. The IP address assigned by DHCP may change over time.
3) Note that the Web Server Function must be enabled on the Web Server tab before the
Remote Access Server Function can be accessed on the panel.
4) Verify that the correct TCP ports have been opened on the router controlling access to the
network where the C-more panel resides.
5) If two C-more panels are on a network behind a firewall and they have the same Remote
Access port number, the router will use the first entry in the Port Forwarding setup that it
encounters. The same C-more panel will always come up even if the two panels have two
different Web Server Port numbers.
6) When entering the URL in Internet Explorer to connect the C-more web server using a
port number other than the default (80), be sure to use the full URL text including the
prefix “http://”. The URL should be http://xxx.xxx.xxx.xxx:aaaaa where xxx.xxx.xxx.xxx is
the IP address of the panel and aaaaa is the port number configured in the Web Server tab
of the Touch Panel Network setting.

Chapter 8: Troubleshooting
PLC Protocol Error Codes
The C-more touch panel includes built-in PLC communication protocol diagnostics that
monitor the exchange of data between the panel and the PLC. The diagnostics look for the
proper exchange of data, correct handshaking signals, addressing errors, incorrect data bytes,
wrong packet format, etc. The diagnostics also monitor and report any of the errors that the
designated PLC would normally generate if there is a problem with the PLC’s communications.
Each brand of PLC has its own unique set of diagnostic errors that are typically communicated
over the PLC’s communications port. The PLC generated errors are interpreted by the C-more
software. See the PLC manufacturer’s user manuals for additional details on the designated
PLC’s errors.
If a C-more communications error does occur, the error message will be displayed in the upper
left of the C-more screen and the Error Code is recorded in the panel’s error log. If a PLC error
occurs, the PLC error code number will appear across the top of the screen, the PLC error
message may not be included in some cases. The error log can be viewed using the system setup
screens. See Chapter 5: System Setup Screens under the Information window to bring up the
Error tab which includes a description of the logged data.
A detailed list and description of the various PLC protocol errors can be found in Appendix A:

Chapter 8: Troubleshooting
Panel Constantly Displays “Initializing” when Powering up
If the touch panel constantly displays a message reading “Initializing” while powering up, then
check the following possible causes.
1.) C-more supports USB 1.0 and 1.1 memory devices. Ensure that the USB device is 1.0 or
1.1 or backward compatible to support version 1.1
2.) The project that is loaded into the panel’s internal SDRAM memory is corrupted. Either use
the C-more programming software to clear the panel’s memory and re-transfer the project to
the touch panel, or press the upper left corner of the touch panel screen while powering up
to bypass the project and go directly to the System Setup Screen menu. Select the Memory
menu, and use either the Clear Memory or Set to Factory Default utility to clear the panel’s
memory and re-transfer the project to the touch panel.
3.) A CompactFlash memory card has been plugged into the CF1 slot and the CompactFlash
either has no project stored on it or the project is corrupted. Remove the CompactFlash
memory card form the CF1 slot and either load the project to the panel’s internal Flash
memory, or use a CF card reader connected to a PC to clear and re-format the
CompactFlash card, or try a different CompactFlash memory card.
Note: In the Error Log you may find the error RTE-500 - Check Sum Error, which is defined as “Memory in
the panel has been corrupted by power loss, etc.” If this is the case, try cycling power to the panel, retransfer the project to the panel, and re-transfer the firmware, etc. in sequential steps to try to correct the
problem.
Data not Logging Problems
If the data log is missing entries, or a Runtime Error for the Log Errors as shown in Appendix
B: Touch Panel Runtime Errors is seen, then check the following possible causes.
1.) Check that the memory devices, that were selected for Data Storage under the C-more
programming software’s Main Menu - Setup drop down - Panel Manager dialog box, are
plugged into their proper location. Alarms, messages and screen captures can be
independently selected to be saved to either a USB pen drive plugged into the USB Port Type A, or a CompactFlash memory card plugged into CF1 or CF2. (Full feature units
only.)
2.) The memory device could be bad. If possible, check it by plugging it into a PC that has the
ability to access the memory device. Also, not all USB devices are compatible with the
C-more touch panels. Check System Screen, Memory for the presence of the USB device
inserted.

If power is cycled to the C-more touch panel and it is then noticed that either
the Date/Time of the panel is no longer correct, or any data that has been setup
to be retentive is inaccurate, most likely the backup battery is exhausted and
needs to be replaced. See Chapter 9: Replacement Parts for additional
information on replacing the panel’s battery.

Electrical Noise Problems
Noise is one of the most difficult problems to diagnose. Electrical noise can enter a system in
many different ways which fall into one of two categories, conducted or radiated. It may be
difficult to determine how the noise is entering the system but the corrective actions for either
of the types of noise problems are similar.
• Conducted noise is when the electrical interference is introduced into the system by way of an
attached wire, panel connection, etc. It may enter through a power supply connection, the
communication ground connection, or the chassis ground connection.
• Radiated noise is when the electrical interference is introduced into the system without a direct
electrical connection, much in the same manner as radio waves.
While electrical noise cannot be eliminated, it can be reduced to a level that will not affect the
system.
• Most noise problems result from improper grounding of the system. A good earth ground can be the
single most effective way to correct noise problems. If a ground is not available, install a ground rod
as close to the system as possible. Ensure all ground wires are single point grounds and are not daisy
chained from one device to another. Ground metal enclosures around the system. A loose wire can act
as a large antenna, introducing noise into the system. Therefore, tighten all connections in your
system. Loose ground wires are more susceptible to noise than the other wires in your system. Review
Chapter 4: Installation & Wiring if you have questions regarding how to ground the touch panel.
• Electrical noise can enter the system through the power source for the touch panel. Installing a
properly wired isolation transformer (neutral grounded) for all AC sources can help the problem, but
only if wired correctly. DC sources should be well-grounded good quality supplies.
• Never run communication cables or low-voltage power wiring close to high voltage wiring or pulse
generating wiring that controls such devices as solenoids, servos, VFOs, etc.
