PROFINET IO 750-370
LED Indication
Remedy
Turn off the supply voltage of the
node, reduce the number of
modules and switch on the supply
voltage again. If the error remains,
replace the buscoupler.
Identify the faulty I/O module.
Turn off the power supply. Plug
the end module in the middle of
the node. Turn the power supply
on again.
- If the LED is keeps blinking, turn
off the power supply and plug the
end module in the middle of the
first half of the node (towards the
coupler).
- If the LED does not blink, turn
off the power supply and plug 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 (while
halving the step size) until the
faulty I/O module is detected.
Replace the faulty I/O module.
Ask for a buscoupler firmware
update.
Switch off the supply voltage of
the node, replace the buscoupler
and switch on again.
Switch off the supply voltage of
the node, replace the buscoupler
and switch on again.
Switch off the supply voltage of
the node, replace the buscoupler
and switch on again.
Restart the coupler by turning the
supply voltage off and on again.
Switch off the supply voltage of
the node, replace the buscoupler
and switch on again.
Switch off the supply voltage of
the node, replace the buscoupler
and switch on again.
Switch off the supply voltage of
the node, replace the buscoupler
and switch on again.
