1-4 What is the PROFIBUS Adapter
Diagnostic Indicators
Diagnostic indicators are located on the front panel of the adapter
module. They show both normal operation and error conditions in
your POINT I/O system. The indicators are:
• Adapter status
• PROFIBUS status
• PointBus status
• System power
• Field power
Upon power-up, the adapter goes to an initialization state and
performs a self-test (memory check, data memory clear, firmware
integrity). The indicators also go through a self-test sequence. If a
failure occurs, the adapter transitions to a faulted state and waits for
reset (cycle power). Otherwise, the adapter begins monitoring the
network (run state) for messages. Chapter 6 describes the diagnostic
indicators and how to use them for troubleshooting.
Network Connector
Use the 9-pin D-shell connector (shown below) to connect your
adapter to the PROFIBUS network.
Connections are provided for connecting the required 24V dc power
to the front of the module.
Refer to Chapter 2 or the Installation Instructions (pub. no.
1734-IN014) you received with your adapter to learn how to install
and wire the adapter.
