Connection via UPS-OCT
A special feature of the Beckhoff CU8130-0120 UPS is OCT (One Cable Technology) as a communication technology between UPS and Industrial PC. The two connection cables (+24 V, 0 V) between the Industrial PC and the UPS are used to supply power to the Industrial PC and for bidirectional, modulated data transmission.
Only the U1out interface of the UPS supports UPS-OCT communication. If you wish to use the UPS-OCT technology, you must ensure that the Industrial PC supports UPS-OCT. You can use the U1out interface to retrieve status data for diagnostic purposes or to configure the UPS.
