USS protocol, 4/6 words
5.8 Standard RS485 interface (X12)
The RS485 interface supports the USS protocol,, which is used to control
the drive converter via a PLC. The USS protocol (Universal S
erial Inter-
face protocol) defines an access technique according to the master-slave
principle for communications via a serial bus.

When using this interface, it should be noted, that the same interface
configuration is set for every bus node.
Exception: "SS1 slave address" - in this case, every bus node has its
own address.
Bus termination
The last node of a bus system must terminate the bus to protect against
the influence of noise. The bus termination is switched-in using a switch
on the control card (refer to Section 5.6, Control terminals).
