FMCS EPICS IOC updated and restarted
Jim B., Patrick T.

WP 6118

The IOC code was updated to directly include the device support code in the build directory instead of linking to a separately built support library. The source code from libavl and c_string was also moved into the IOC build directory.
The IOC database was updated to add the humidity channels listed here: https://dcc.ligo.org/LIGO-L1600108

I ran into some build issues stemming from the fact that h0epics2 is running Ubuntu 10.04.4 and the repositories for it have been taken down. I instead compiled and started it on h0epics (Ubuntu 12.04.5), after Jim B. installed libcurl4-openssl-dev, make, g++ and libreadline.

I noticed that the H0:FMC-MILLIAMP_MAXVAL channel has not been set and has thus been defaulted to 0. This is used in the conversion from milliamps to percent for a number of records. As a result these records have had values of inf (divide by 0). I set H0:FMC-MILLIAMP_MAXVAL to 12.0. Perhaps this should be hardcoded in the database.

The added humidity channels are:
H0:FMC-CS_OSB_RM132_RH_PCT
H0:FMC-CS_OSB_RM161_RH_PCT
H0:FMC-CS_OSB_RM162_RH_PCT
H0:FMC-CS_OSB_RM163_RH_PCT
H0:FMC-CS_OSB_RM165_RH_PCT
H0:FMC-EX_DIS_RH_PCT
H0:FMC-EX_OSA_RH_PCT
H0:FMC-EX_SPACE_RH_PCT
H0:FMC-EY_DIS_RH_PCT
H0:FMC-EY_OSA_RH_PCT
H0:FMC-EY_SPACE_RH_PCT
H0:FMC-LVEA_AHU1_DIS_RH_PCT
H0:FMC-LVEA_AHU1_OSA_RH_PCT
H0:FMC-LVEA_AHU1_SPACE_RH_PCT
H0:FMC-LVEA_AHU2_DIS_RH_PCT
H0:FMC-LVEA_AHU2_OSA_RH_PCT
H0:FMC-LVEA_AHU2_SPACE_RH_PCT
H0:FMC-MX_DIS_RH_PCT
H0:FMC-MX_OSA_RH_PCT
H0:FMC-MX_SPACE_RH_PCT
H0:FMC-MY_DIS_RH_PCT
H0:FMC-MY_OSA_RH_PCT
H0:FMC-MY_SPACE_RH_PCT

These channels are not yet in the DAQ.

I burtrestored the IOC to earlier this morning to set the alarm levels.

I've added them to H0EDCU_FMCS.ini and they will go in on the next DAQ restart. I checked that the new channels exist.
