I/O (first level)
This menu displays the state of the IO on the unit. An IO that is in the OFF state is
shown in red, an IO that is in the ON state is shown in green, and the IO that are not
programmed are turned off (black). In Figure 11.6, IO 2 and 4 are in the ON state, IO
6 and 8 are in the OFF state, relay 15 is in the OFF state, and relay 16 is in the ON
state.
External errors on inputs and outputs are indicated on the display by lighting the
number corresponding to the terminal in orange. When an external error is detected
the display will automatically jump to the I/O menu until the error has disappeared
and been reset. If the error is currently present (i.e. the short circuit is still present,
and the terminal is still detecting an external voltage), the LED is constant orange.
When the error has disappeared and has not been reset in logic, the terminal LEDs
blink orange.
Terminals that are in the same input/output function group as another terminal with
an external error, are indicated by a short, fast, orange blink. This means that the
terminal itself does not have an error but is in an IO function that has an error.
