353DP slave
3-22
After power on, the DP slave executes a self test. It controls its internal
functions and the communication via the backplane bus. After the error free
start-up, the bus coupler switches into the state "ready". In this state, the
DP slave gets its parameters from the DP master and, at valid parameters,
switches into the state "DataExchange" DE (DE is permanently on).
At communication errors at the backplane bus, the PROFIBUS slave
switches into STOP and boots again after app. 2 seconds. As soon as the
test has been completed positive, the RD-LED blinks.
