Practical example: DMX slave
The EL6851-0010 DMX slave terminal enables the integration of DMX applications into PC-based control technology and
unites the advantages of both systems: lighting control via DMX whilst at the same time using standard components.

PC Control technology:
Fig. 7 Integration of PC-based control technology by means of the EL6851-0010 DMX slave terminal
The modularity of the Beckhoff I/O system offers a suitable terminal for every signal, so that the type of signal and the number
of channels are matched to the application. Non-DMX-capable devices such as DALI lamps or universal dimmers can also be
addressed via the Beckhoff I/O system. When using drive technology (moving stage elements etc.), low-priced standard drives
such as stepper, servo or DC motors can be integrated simply via the appropriate EtherCAT terminals. The control technology
is scalable: the required performance class can be selected from the extensive product range, from Industrial PCs to the local
Ethernet controller. The long-term operation of the application is ensured by the simple extendibility and changeability of the
system: additions and conversions can easily be integrated.
