Troubleshooting Chapter 7
Cannot Download
Application to Terminal You are unable to download an application to the terminal.
Performance Is Slow If the response time of the application is slow, for example screen changes or text
display changes, check for the following conditions:
•
Application screens that contain too many elements
•
A controller that is programmed for feedback can cause delays
•
Slow network performance or noise can result in retries
Resistance to Chemicals The outer surfaces of the terminal including the bezel, touch screen overlay, and
panel sealing gasket are tested for chemical resistance. Some of the chemicals can
cause discoloration, but they do not interfere with the operation of the terminal.
Poor cable connections Check the Ethernet cabling for the following:
• Make sure that cables are fully connected.
• Check for cable crimping.
• Check the Ethernet switch connections.
• Check the Uplink ports.
Invalid IP address of terminal If DHCP is enabled, the terminal automatically acquires a valid IP
address from the network after startup. The TCP/IP protocol
automatically assigns 169.254.
xxx.xxx
when it fails to acquire an
IP address from the network. In general, an IP address that begins
with 169 does not support a network connection.
See
Configure the IP Address of the Terminal on page 48 .
Conflict Between IP addresses If DHCP is not enabled and a static IP address is specified, make
sure that the IP address does not conflict with the address of
another device on the network.
See
Configure the IP Address of the Terminal on page 48 .
Table 28 - Ethernet Connection Issues (Continued)
Check for Description
Table 29 - Unable to Download Project to Terminal
Check for Description
Application downloads are disabled in Settings
screens Verify that downloads are enabled. See Disable Downloads to the
Terminal on page 57 .
Download of project to correct HMI device Check the following in the View Designer application:
• The project downloaded to the correct HMI device
• IP address of HMI device is correct
Ethernet connection Make sure an Ethernet cable is connected between the computer
and terminal.
Verify that the Ethernet port is configured properly. See
Configure
the Ethernet Ports on page 51 .

IMPORTANT
Do not operate the terminal in direct sunlight. Direct exposure to ultraviolet
light can discolor the touch screen.
