6.3 Communication
There are several ways to communicate with the UPS, for example to query the status or to control the
device state until shutdown.
The following options are available:
• Protocol-based communication via UPS-OCT (One Cable Technology) or USB.
• Digital signals for communication with non-protocol-capable end devices.
• TwinCAT PLC function blocks for querying the UPS operation.
The configuration and diagnosis of the UPS-OCT or USB communication method is carried out via the
Beckhoff UPS software on Windows 7 or Windows 10.
6.3.1 Connection via UPS-OCT
A special feature of the Beckhoff CU8130-0240 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.
