Andy	Hi, I don't know the answer but it sounds like a problem with the Tango database. How did you install the Tango database? Where did you find the conda package so I can try to run it myself. Andy

Hi Dariusz, It looks like you're using a too old version of the Tango Database server (Tango 8?) which does not support yet the DbGetClassPipeProperty command. You need to use a more recent Tango Database server if you want to use Tango 9 device servers which are using the pipe feature. Kind regards, Reynald Rosenberg's Law: Software is easy to make, except when you want it to do something new. Corollary: The only software that's worth making is software that does something new.

DariuszIE TangoSetup-8.1.2b_win64 This is Tango 8 and Tango 8 does not support pipes (a feature which is used by this test PowerSupply device server). You need at least a Tango 9 Tango Database Device Server to use the pipe feature. Kind regards, Reynald Rosenberg's Law: Software is easy to make, except when you want it to do something new.
