The USS protocol (

U

niverselle 

s

erielle 

S

chnittstelle = universal serial 

interface) is a serial transfer protocol defined by Siemens for the drive and 
system components. This allows to build-up a serial bus connection 
between a superordinated master and several slave systems. 
The USS protocol enables a time cyclic telegram traffic by presetting a fix 
telegram length. 
 
The following features characterize the USS protocol: 

• 

Multi point connection 

• 

Master-Slave access procedure 

• 

Single-Master-System 

• 

Max. 32 participants 

• 

Simple and secure telegram frame 

 
You may connect 1 master and max. 31 slaves at the bus where the single 
slaves are addressed by the master via an address sign in the telegram. 
The communication happens exclusively in half-duplex operation. 
After a send command, the acknowledgement telegram must be read by a 
call of the SFC 218 SER_RCV. 
 
The telegrams for send and receive have the following structure: 
 

Master-Slave telegram

A request may be directed to a certain slave ore be sent to all slaves as 
broadcast message. For the identification of a broadcast message you 
have to set Bit 5 to 1 in the ADR-Byte. Here the slave addr. (Bit 0 ... 4) is 
ignored. In opposite to a "normal" send command, the broadcast does not 
require a telegram evaluation via SFC 218 SER_RCV. Only write 
commands may be sent as broadcast.
