What steps should I go through to troubleshoot the RSLinx Classic Ethernet driver?

In the RSLinx Classic Ethernet driver configuration, set
Address Mapping
 to
ON
. Enter the IP address of the processor as station 1 (1:223.254.254.79). Save the configuration. Go to RSWho. If the device does not appear as station 1, check that the RSWho is set to
Local
. If unsuccessful, continue through the following steps.
  1. From your computer, PING the processor. (PING is an echo request. The destination station echos the packet back to the source station.)
    • If successful, skip steps 2 through 4.
    • If unsuccessful, your computer cannot communicate with the processor. It could be hardware, software, cabling or configuration of the processor.
  2. PING your own computer, from itself.
    • If successful, the software is installed and running.
    • If unsuccessful, check your autoexec.bat file for loading the drivers. Also, check the configuration files for the network drivers. These may include
      NET.CFG
       and
      PCTCP.INI
       for FTP Software’s PCTCP product. If using MS-TCP/IP software with Windows for Workgroups, check the configuration in the
      Network Setup
      .
  3. From a different computer, PING your computer.
    • If successful, your computer is connected properly onto the network, and the TCP/IP software is configured correctly.
    • If unsuccessful, it could be the hardware. Check that the network connection is secure to your computer. Some transceivers will have LEDs indicating
      TX
       or
      RX
       activity. These can be used to see if any signals are getting to your computer. It could also be the TCP/IP configuration. Compare the IP address and subnet mask for your computer with the other computer. The subnet mask will be the same for both, if they are on the same subnet. At least 2 octets of the IP addresses will be the same, depending upon the class of your Ethernet network. (Class C has the first 3 octets (digits) the same. Class B has the first two. Class A has the first.) If you are relying on bridges and routers, make sure that they are running properly. Also be sure that the TCP/IP driver is configured to use the router when it is neccessary.
  4. From your computer, PING the processor.
    • If successful, the network connection appears as expected.
    • If unsuccessful, check that the processor is configured. The ethernet channel of PLC-5/E processors, must be configured before use. This can be done with a BOOTP server or from DH+, using PLC-5 programming software. The 5820-EI module must be configured from Ethernet, using a BOOTP server, with TFTP (trivial file transfer protocol) capability. The BOOTP server provides both an IP address and a binary file,
      SGMPCCC.BIN
       to the 5820-EI module.
If the processor is configured, check the IP address and subnet mask against that of your computer.
If they are on the same subnet, they must have the same subnet mask and same network address.
Class C: IP address = xx.xx.xx.yy where xx=network address and yy=host address
Subnet mask 255.255.255.0
Class B: IP address = xx.xx.yy.yy
Subnet mask 255.255.0.0
If the two are on different subnets without a router, make sure that the subnet mask used for each will include addresses from the other subnet.
Class B: IP address = 130.100.175.222 and IP address = 130.100.172.111
Subnet mask = 255.255.252.0 to include both
If there is a router, check that your computer’s TCP/IP driver is configured to use the router. Check that the router is running.
