h1spih23 Front-end Model Bug Fix for ADC3 map of REF and MEAS PDs
J. Kissel As I'm building up the MEDM screens for SPI, I'm finding some bugs in the Simulink model. This one: According to D2400111-v6, and the ADC/DAC Channel Usage Table in G2401479-v3, ADC3 CH20 = PWRIN_REF and ADC3 CH21 = PWRIN_MEAS. The initial release of the SPI model at LHO (LHO:89777, ${USERAPPS}/spi/h1/models/h1spih23.mdl userapps svn rev r34928, ${USERAPPS}/spi/common/models/SPI_LIBRARY.mdl rev r30005) had these flipped with ADC3 CH20 = PWRIN_MEAS and ADC3 CH21 = PWRIN_REF. I've fixed the bug, and the top level and library are now at rev r35060 and r35059 respectively, and Dave's installing / restarting for me. No DAQ restart required, as it's just simulink wires getting uncrossed.

The only issue we had with the install was a file permission on the filterfile userapps/spi/h1/filterfiles/H1SPIH23.txt (was not controls group writable). After fixing the permissions the install proceeded normally and the model was restarted at 14:07 with no DAQ restart needed.
