Diagnostics and troubleshooting
There is a two–color LED with the following significance on the front of
the optional PROFIBUS DP module:
Red
Flashing
Red
Steady light
The module has still not be started from the control board or
it has not been enabled (P0875)
The module has been enabled (P0875) and started from the
control board, there are no cyclic communications
(MSCY_C1, Data Exchange, net data transport) between the
master and this module as PROFIBUS slave or there was a
communications failure (watchdog)
Check! (if cyclic communications was previously active):
–
is the DP slave node address correct
(P0918
≠
0)?
–
is the bus connection OK?
–
terminating resistor?
–
are all of the bus cables inserted?
The module has an internal, fatal error
Counter–measure:
Execute POWER–ON RESET
Replace the option module
The module is enabled (P0875) and has been started from
the control board, cyclic communications has been
established (MSCY_C1, Data Exchange, net data transport)
between the master and this module as PROFIBUS slave
