WP 7757 I have updated the PLC code on h0vacey for the change of IP11 to a gamma controller. I ran into an unexpected problem during this. The ETM, NEG1 and Y2-8 BPG402 pressure gauges are version V1_2_1_0 and the NEG2 BPG402 pressure gauge is version V1_3_0_0. The names of the IO variables differ between these versions, and the PLC code only has the names for V1_3_0_0. I'm not sure why this became a problem now. I have set all the gauges to use version V1_3_0_0 of the ESI file and this does not appear to be an issue. I will leave this in place until I can add the names for V1_2_1_0 to the PLC code. I have burtrestored h0vacey to 6 am today. A DAQ restart is still required. Richard has gone to end Y to reset the high voltage.
