Remote maintenance via ORA11B

Straightforward and reliable access via remote maintenance

Remote maintenance provides a convenient engineering access to the controllers.
SEW-EURODRIVE provides several solutions depending on the plant topology:
The simplest solution merely requires an analog phone line. The ORA11B modem converts signals for ETHERNET so that 'standard' and 'advanced' controllers can be easily addressed. This is an ideal solution if the stand-alone method is used to automate an entire machine. Alternatively, the controller can be addressed via a higher-level central PLC.
