TROUBLESHOOTING THE SNAP PAC R-SERIES CONTROLLER

•
Make sure you have up-to-date drivers installed on your computer’s Network Interface
Card (NIC). Contact your system administrator or the manufacturer of the card for help.
•
Make sure you have Administrator privileges on your computer and that any firewall in
the computer (such as the built-in firewall in Windows XP) is temporarily disabled
before you try to assign or change IP addresses, load firmware using PAC Manager’s
Maintenance window, or work with files on the controller. BootP and FTP cannot
function through a firewall in the PC. Firewalls in a router are less likely to be a problem
unless certain ports (such as FTP client) have been blocked, either by default or on
purpose.
Pinging the Controller
If you still cannot communicate with the controller after you have checked these items, try
to reach it using the PING protocol.
1.
Choose Start
>
Programs
>
Accessories and open a command prompt.
2.
At the prompt, type:
ping [controller’s IP address]
For example, type:
ping 10.192.54.40
If the controller responds,
go to
“Accessing the Controller with PAC Manager” on
page 70
.
If the PING command cannot be found
, choose Start
>
Control Panel
>
Network. Make
sure TCP/IP is configured as a protocol and that an IP address and subnet mask are assigned.
If you see the message “Destination host route not defined,”
the controller probably
has an inappropriate IP address and subnet mask. Make sure the IP address and subnet
mask on the controller are compatible with those on the computer. Follow the directions
beginning on
page 48
to check the IP address and subnet mask on the controller, and
change them if necessary.
If you see the message “No response from host,”
check the following:
•
Are the computer and controller correctly connected? Is the controller turned on?
•
Are the IP address and subnet mask on the controller compatible with those on the
computer?
•
Is the controller in reset mode? (Check for a blinking STAT LED. STAT blink codes are
shown on
page 65
.)
If you still cannot ping the controller,
contact Opto 22 Product Support. (See
page 6
.)
Accessing the Controller with PAC Manager
Once you know you can ping the controller, try to access it using PAC Manager. You will
need to know the controller’s IP address.
1.
If PAC Manager is not already open, choose Start
>
Programs
>
Opto 22
>
PAC Project
>
PAC Manager.
The PAC Manager main window opens:
