Hi All Like to run an issue by u ,..Coding in Labview I have USS communication set up with a 6RA70 and link seems ok,.. I can change parameter 51 ( allowing changing of all other parameters ). However if I try and change any other parameter like accel or decal rates,.. simoreg drive responds with "cannot process request, task cannot be executed" PWE comes back as 5 ,.. tried changing formatting ,.. no good,.. cannot change any other parameter ,...thoughts ????

Hi kv8vsa,
I assume you have troubles with the PKW and PZD areas in your telegram. Take a look at the following documentation from Siemens and change accordingly on your inverter so you can change Integer or float parameters in EEPROM or RAM.

If the previous document was not good enough, here you have a more comprenhensive explanation of the USS protocol:

Hi All,
Right now, i'm developing custom Linux board which use to collect data + control equipment.
most of these equipment using modbus protocol,
one of equipment is MM440 motor drive, using USS protocol, and I'm new to USS protocol.
because I'm in Linux environment I'm also not familiar with LabView etc.
so, does anyone ever develop library using C or C++ library of USS protocol?
or any other language which can be compiled on Linux environment?
FYI: using Debian embedded for ARM.
any help would be much appreciated
Thanks
