Unmapped Network Node XX on CH.
Y On
Node XX is connected to and
communicating on the network via
Channel Y but is not registered
• Add node to network. Refer to
Section 3-2.5.2.4.44. This is not
sufficient by itself. See next step.
• Review network settings and
required interactions among
control units in the applications
program. Make any necessary
corrections and re-upload
configurations again to all effected
nodes.
• Check wiring to NIC in Node XX.
See Section 2-17. Ensure that
network wiring is daisy-chained
and not T-Tapped.
• Check network wiring for excess
resistance or capacitance.
• Check connection of NIC to main
printed circuit board Header J5.
See Figure 1-8 and Section 2-17.
