I/O Error Mode

In I/O Error Mode, the status of all the outputs will be set to values and states as defined in
the fault action and value selections of the discrete output object. The I/O Status LED may
be solid red. This condition can be caused by an I/O Bus fault, such as a module being
removed. The I/O Status LED could also be flashing red. This condition can be caused by a
DeviceNet connection timing out. For full definition of LED conditions refer to the I/O
Status LED
in Chapter 5
.

I/O Idle Mode

In I/O Idle Mode, the status of all the outputs will be set to values and states as defined in the
idle action and value selections of the discrete output object. The I/O Status LED will be
flashing green. For full definition of LED conditions. refer to the I/O Status LED in
Chapter 5.
