Hi Mark,

I am passing the former.

BTW, I have configured the IOC with ASYN_MULTIDEVICE, and maxAddr 5.

Cheers,

Peter.

I suspect you are passing the wrong pasynUser to getAddres(). Are you passing the one that was passed into writeInt32 or the pasynUserSelf? You should pass the former.

Hi Mark,

I’m sorry to trouble you.

In my application I am seeking to connect multiple devices (i.e. multiple pumps, in this case).

So, for example, I have record names like:
TURBOSIM:5:WarningTemperature (5 being the last of 5 devices connected).

I had expected asynPortDriver::getAddress to emit the index of the device being addressed (0..4, in this example).

But the only address value I can detect being emitted from the method, is 0 (e.g. when called within readInt32).
I believe it is being invoked with asynUser(s) that are correctly associated with a specific device.

What could I be missing?

Many thanks,

Peter.
