14.3.2 "IO" function
With this setting, the IO axis bus is used as a pure IO transmission medium, just like it the case for
the 9300 and 9400 device series.
The "IO" function is activated in
C02440/1 by selecting "3: IO".
• By setting the LS_AxisBusIO .bSetFail_DigOut input to TRUE, the IO axis bus is set to the
dominant level and for all nodes, the LS_AxisBusIO .bFail_DigIn output is set to TRUE.
• The LS_AxisBusIO .bResetFail input has no function.
• The LS_AxisBusIO .bResetFail_In output is always FALSE.

Note!
• "IO" function and Data transfer axis bus are mutually exclusive since with activated
"IO" function, a synchronisation of the internal time base is not possible (which is
required for a "safe" data transfer).
• The "IO" function must be set for all IO axis bus nodes.
• Triggering an error message with this function is only possible by function block
interconnection.
• Resetting an error message is not possible with this function.
