Last Maintenance Date
The dates on which maintenance is performed can be written to the
DeviceNet Communications Unit. The recorded date shows when mainte-
nance is required next.

System Configuration
The DeviceNet Communications Unit connects to the Master by a network
cable and it connects to the Slice I/O Units by directly coupling the Units with
slide connectors.
The I/O Unit data in the DeviceNet Communications Unit is shared with the
Master’s Input and Output Areas through the DeviceNet network. The I/O
Units’ data is collected in the DeviceNet Communications Unit and exchanged
with the Master asynchronously.
It is also possible to send explicit message commands addressed to the
DeviceNet Communications Unit.
Note
Always install an End Unit on the last I/O Unit in the last node.
