Mostly 0 due toconverter - DRIVEMONITOR coupling. (Depending on the pin RS485 or RS232). i002 = SCom2: bus address of the ser. interface 2 (CU), on -X101 pin 10, 11, 12 (RS485) i003 = SCB: bus address of the SCB, if P696 = 1, 2 follow the compendium of the MASTERDRIVES VC section 8.1 USS communication. http://support.automation.siemens.com/WW/view/en/13472409 By using the interface on the cuvc board directly, the index 2 is valid. Sure each participanthas to have an other bus adress. By the way, the bit no 10 in the first transmitted word has to have "High" level. Please consider, the USS bus allowes one master and 31 slaves
