Hello Mark,I discovered this using asynFloat64 device support (with modbusTCP driver), then made a specific test with Raw Soft Channel and finally looked in the code of the ao record and in the convert function there is a cast to (epicsInt32) ...

Conversion to epicsInt32 is not normally part of the operation of the ao record. What device support are you using?

This is surprising and not equivalent to what is done for the ai record. Could this be changed ? Regards, Christophe
