USS protocol, 4/6 words
Standard interfaces RS485 (X12)
The RS485 interface supports the USS protocol, which is used to control
the drive converter via a PLC. The USS protocol (Universal Serial Inter-
face Protocol) defines an access technique according to the master-slave
principle for communications via a serial bus. You can obtain a detailed
description of the USS protocol from REFU, or from the Internet under
http://www.refu.com.

When using this interface, it should be observed, that each bus node
(station) should have the same interface configuration.
Exception:
"SS1 slave address", in this case, each bus node (station)
has its own address.
