Diagnostic Indicators
Health indicators are located on the front panel of the adapter module (Figure 1).
They show both normal operation and error conditions in your remote I/O
system.
In addition, an alphanumeric display (net address/status) provides status code
indications when an error occurs during initialization or operation.
A complete description of the diagnostic indicators and status display and how to
use them for troubleshooting is explained on page 13.
Network Access Port (NAP)
The network access port (Figure 1) provides a bidirectional electrical interface
for programming, maintenance, and I/O monitoring devices in both redundant
and non-redundant connections. Connecting programming terminals to the
network using the NAP is described on page 11.
