If the field bus node comprises internal system
supply module (750-613), make sure first that the
power supply of these modules is functioning.
This is indicated by the status LEDs. If all I/O
modules are connected correctly or if the field bus
node does not comprise 750-613 module you can
detect the faulty I/O module as follows:
turn off the power supply of the node. Place the
end module in the middle of the field bus 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.
If there is only one module on the coupler and the
LED is blinking, either this module or the coupler
is defective. Replace the defective component.
