The scanner gathers drive status data via the DeviceNet
network. The M-File is copied into the N9 data file in the SLC
to move the drive status information to a convenient location.
These rungs move the drive status from
the N9 data file to an operator display.
These rungs move the inputs of the
operator from the operator station to the
N9 data file. They will then be sent to the
scanner and out to the drive via the
DeviceNet network.
