Hi Iain,

Is your driver based on asyn?

If so, your setter records you can add the info tag asyn:READBACK.  This will force the setter (output) records to update their values based on a callback from the driver.  It is documented here:

Subject: CSS Text entry values not updating on PV change

I am trying to update some text entry boxes with values from the IOC.  The controller ultimately sends and receives many parameters as a single block.  I have set up the IOC to have separate getters and setters that batch the values and transmit them.  I have text entry widgets for the setters and text update widgets for the getters.  What I would like to do on a Get operation is populate the setter widgets with the getter values.  I have tested this with caget and can see that the PV values are populated when I do a get, but the values in the CSS BOY GUI do not update.  Is there some way to populate the text entry widgets from the PV?

Thank you,

Iain.
