Mode switchover error
This error is output if you change the mode of the block from
● Manual to automatic mode or
● Local to automatic mode
and the previous state and the target state mismatch (bumpless changeover). You can only
change the block mode if the subsequent state corresponds with the previous state.
You can activate/deactivate bumpless changeover by setting bit 17 at the Feature I/O
(bumpless changeover to automatic mode).
The bumpless switchover from local to automatic mode is made using the LocalSetting
parameter as described in the "Local mode" section in the APL Online Help.
In the standard view of the faceplate, the text "Changeover error" is displayed in the event of an
unwanted switchover with bumps.
The block retains local mode if the operator changes the mode from local to automatic and the
error mentioned above occurs. The block changes to manual mode if the mode is changed from
local to automatic over interconnected inputs and the error mentioned above occurs.
