I encountered some problems yesterday in moving the Beckhoff system at end Y from H2 to H1. The links were lost when I did a global search and replace in the PLC code to change H2 to H1. It is now running with H1 EPICS channel names, but as a temporary hack. The internal variables are still running as H2, I just changed the names to H1 in the EPICS database records. I will try doing a more selective search and replace and see if the links are still lost.

I also had to remove ONAM and ZNAM fields from a long record type. This will have to be fixed in the Beckhoff code, I believe in one of the libraries.
