MicroMaster440 direct control over USS

Hello specialists,

I am new on Siemens Drives, and have a MicroMaster440 connected to asynchronous motor. I need to read data to PC. I am getting all data into DriveMonitor software over the RS232 port, but I will need it to have in Matlab. But at first I can't read it even into simple Docklight RS232 Terminal/RS232 monitor. I am sending simple parameters request to the Drive, e.g.: 02 12 00 12 BC 00 00 00 00 00 00 02 BD., and I do not have any replay from Drive. Using simple null-modem cable (stright connected).

By the way, maybe there should be some parameters set in drive before using USS protocol over the RS232 not RS485.

I will really appreciate your help.

BR,
Vyto.

Hi,

The Micromaster manuals are excellent and you should find the parameter list most useful. You will need to tell the drive where its instructions are coming from (USS), the Baud rate and what its Address is. You may also want to set a timeout to stop the drive if it loses USS contact.

The USS protocol is fully published and is available on the Siemens Website, so once you have it talking, building a dialogue should be easy.
