The temperature probes are acquired at 100Hz by the ADC7674 SN43 labelled as "TCS_ADC_Moni2" located into the TSC room using the following channels, the bias and the slope remains to be tuned
- ADC7674_CHANNEL TCS_HWS_NI_TE1 2 100 Butterworth_8_20dB 0. +1 "V"
- ADC7674_CHANNEL TCS_HWS_NI_TE2 3 100 Butterworth_8_20dB 0. +1 "V"
- ADC7674_CHANNEL TCS_HWS_WI_TE1 4 100 Butterworth_8_20dB 0. +1 "V"
- ADC7674_CHANNEL TCS_HWS_WI_TE2 5 100 Butterworth_8_20dB 0. +1 "V"
These channels are sent to the SUSP_rtpc(rtpc4) and made available for 2 dedicated Acl servers: TCS_HWS_NI and TCS_HSW_WI running at 100Hz
These servers have been setup using a configuration already tested in the Virgo RD VPM domain with few minors modifiactions:
- an ACL_RELAY_CH called ENBL has been added to enable the loop and to reset the filters when the loop is opened
- the filter computation method has been set to use the long double computation to reduce the possible digital noise
- a include file with the filters definition has been created to ease the filters modification
- the correction channel CORR_U has been made available as 64 bits double for the server TCS_CEB mananing the DAC1955 SN40
The TCS_CEB server, running at 10KHz,
- read the TCS_HWS_{NI,WI}_CORR_U (line25-26)
- extend the channels at the DAC1955 running frequency(100KHz)
- implement a clipping (line 72-73) at 0 and 1V after the channel extension to be tuned if needed
