Remedy
- Switch off the power to the controller
and replace it.
- Then switch the power back on.
- Switch off the power to the
controller.
- Reduce the number of I/O modules.
- Switch the power back on.
- Update the controller firmware. If this
error persists, there is an error in the
I/O module. Identify the error as
follows:
- Switch off the power supply.
- Place the end module in the middle
of the I/O modules connected to the
system.
- Switch the power back on.
- If the I/O flashes red switch off the
power supply again and place the
end module in the middle of the first
half of the I/O modules (toward the
controller).
- If the LED is no longer flashing,
switch off the power supply and
place the end module in the middle
of the second half of the I/O modules
(away from the controller).
- Switch the power back on.
- Repeat this procedure until you
establish which I/O module is
defective. Then replace that module.
- Switch off the power to the controller
and replace it.
- Then switch the power back on.
- Switch off the power to the controller
and replace it.
- Then switch the power back on.
- Restart the controller by first
switching off the power supply and
then switching it back on, or
by pressing the Reset button on the
controller.
