nans in wa

[dschick]

maybe this is related to #1411

in wa all motors from one specific controller give NaN for dial and user position but in wuthey are all fine.

If I do wa mot1 and wa mot1 mot2 it is still fine.
If I do a wa mot1 mot2 mot3 two of them are NaN and with a fourth motor all of them are NaN.
Motors from other controllers do not affect this behavior at all.

The controller which I am using is rather slow, so I guess there is some timing condition met when I ask too many motors at the same time ...

Hi @dschick,
I imagine there are some exceptions when reading (Position and DialPosition). If yes, these should be logged

sardana/src/sardana/macroserver/macros/standard.py

Line 116 in 69e6ed7

self.debug('Error when reading %s position(s)' % name)

Could you please attach the following macros execution logs:

• wa mot1 mot2 mot3
• wa mot1 mot2 mot3 mot4

Many thanks!
