The scanner gathers drive status data via the DeviceNet network. The Block Transfer Read
in this rung then moves the drive status data from the scanner to the N9 data file in the PLC.
These rungs move the drive status from the Block
Transfer Read data file to an operator display.
This rung enables the scanner.
These rungs move the inputs of the operator from
the operator station to the Block Transfer Write
data file. They will then be sent to the scanner
and out to the drive via the DeviceNet network.
