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.
