Experimental Physics and
Industrial Control System

Hej Tim and all,

We actually got the slit working in the motion controller.
I have, anyway, used the 2slit.db, mainly for testing & learning.

For the motor module, I use a patched version, which keeps the record
in UDF state, until the poller has really talked to the controller.
As a result, the soft motors sometimes (depending on the timing)
stay in "link alarm".
A movement will make the alarm disappear.

Do you think we can go through the db file next week,
some help is wanted.
