Figure 3.7 Example Network Diagnostics Status Response
Comm
The Comm button verifies communications between the PCLTA-20 adapter and
another node on the network. When this function is chosen, a dialog will appear
asking for confirmation of this command, as follows:
This procedure will configure the Network Interface for a zero-
length domain if it is not already configured. Do you want to
proceed?
Choosing OK causes the control panel to first check the network interface for the
configured state. If it is already in the configured state, it will not be modified
further. If it is not in the configured state it will install the network interface with a
zero-length domain on index 0, a subnet of 1, and a node ID of 126, and then change
its state to configured.
Once the node is in the configured state, the control panel enters the receive-ready
state and displays the following message while waiting for a service pin message
from another node on the network:
Now waiting for a service pin message.
Once the service pin is activated on the other node and a service pin message is
received, the control panel sends a request/response diagnostic message to the other
node using Neuron ID addressing. It will repeat this message, referred to as a
“ping,” once per second until either the ‘OK’ or the ‘Quit’ button is chosen (the Quit
button will appear in place of the Comm button).
This series of tests confirms that the device can be configured and can communicate
with a node on the network. The Comm function is intended to eliminate the
PCLTA-20 adapter, the card drivers, the network connection, the hardware of the
other node, and the topology configuration from the list of possible problem points or
points of failure during network troubleshooting. The Comm function test does
not
eliminate the possibility that the wrong type of media has been used. Be sure that
the medium is suitable for use with the selected channel type. The Comm function
also does not eliminate the possibility of a missing or improper network termination.
