Detect faulty I/O module as
follows: turn off the power supply.
Place the end module in the middle
of the fieldbus node. Turn the
power supply on again.
– If the LED is still blinking, turn
off the power supply and place the
end module in the middle of the
first half of the node (towards the
coupler).
– If the LED doesn't blink, turn off
the power supply and place the end
module in the middle of the second
half of the node (away from the
coupler).
Turn the power supply on again.
Repeat this procedure until the
faulty I/O module is detected.
Replace the faulty I/O module.
Ask about a firmware update for
the fieldbus coupler.
Turn off the power supply of the
node, reduce number of I/O
modules and turn the power supply
on again
Turn off the power supply of the
node, exchange fieldbus coupler
and turn the power supply on
again.
Turn off the power supply of the
node, exchange fieldbus coupler
and turn the power supply on
again.
Restart the fieldbus coupler by
turning the power supply off and
on again.
Turn off the power supply of the
node, exchange fieldbus coupler
and turn the power supply on
again.
Turn off the power supply of the
node, exchange fieldbus coupler
and turn the power supply on
again.
Turn off the power supply of the
node, exchange fieldbus coupler
and turn the power supply on
again.
Adjust the clock and keep upright
the supply voltage of the bus
coupler for at least 15 minutes for
loading of the Goldcaps.
