IOLAN+ Still Does Not Communicate
A situation may occur which causes the IOLAN+ to completely not function. Here are
possible problems
:
Problem Action required
Port locked Try killing the port as it may be locked due to some
situation that is no longer obvious. Also, killing the port
ensures that any changes in the configuration will be
acted upon.
Power cycling Power cycle the device connected (if this is possible) as
it may be that it has locked, or the set-up within the
device is in error. Also try power cycling the IOLAN+
itself.
Network errors Try 'pinging' the IOLAN+ to establish connection.
Network cable problems Check the network cable again. Does it work on another
node correctly. Is the BNC (or AUI) connector fitted
correctly?
Configuration problems Check the IP address again on the Server Menu.
Power problems Is the green LED power light on? Check the power itself
with the plug, wall socket, fuses, etc. Is the green LED
power light dim? Call your supplier or Perle support.
Hardware problems If all three network LEDs are flashing continuously on/off
at approx 4Hz. this may point to a memory fail test.
Call your supplier or Perle support.
