2.5 PROFIBUS Adapter Components
The adapter module consists of the following components:
ƒ
two diagnostic indicators
ƒ PROFIBUS DP network connector
ƒ 24V dc power wiring connection terminals
ƒ two node address switches
2.5.1 Diagnostic Indicators
Diagnostic indicators are located on the front panel of the adapter module. They
show both normal operation and error conditions in your FLEX I/O system. The
indicators are:
ƒ
Device status (STATUS)
ƒ Communication link status (PROFIBUS)
Upon power-up, the adapter goes to an initialization state and performs a self-
test (memory check, data memory clear. 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 5 describes the diagnostic indicators and how to use them for
troubleshooting.
2.5.2 Network Connector
Use the 9-pin D-shell connector to connect your adapter to the PROFIBUS
network.
