Daniel, Elli, Patrick, Nutsinee I changed the OPC_PROP_RIGHTS of PostionDetector2SUMGain from 1 (read only) to 3 (read/write) in the HartmannSensor library code. I checked the change into SVN. I updated from source, recompiled and restarted PLC3 on h1ecatc1. Yesterday Nutsinee made a code change to PLC1 on h1ecatc1 and checked it into SVN. This was to fix the picomotor labels. I updated from source, recompiled and restarted PLC1 on h1ecatc1. I restarted the EPICS IOC on h1ecatc1. I did caputs to H1:TCS-ITMX_HWS_POSITIONDETECTOR2SUMGAIN and H1:TCS-ITMY_HWS_POSITIONDETECTOR2SUMGAIN to change them from 0 to 1. WP 5199, 5200
