The LS_DeviceMonitor system block provides the status signals of the motor control in the function
block editor.
[5-36] LS_DeviceMonitor system block (excerpt)
Outputs

Note!
The LS_DeviceMonitor system block can only be inserted on the application level.
If status signals of the motor control function are to be output via digital outputs or
example, you can use the free bFreeOut1 ... bFreeOut8 outputs of the application block
to transfer the desired status signals from the application level to the I/O level. On the
I/O level, you can then establish the logical link to the digital output terminals.
