Running IOC to convert CP1 Regen temp gauge signal to PT100A EPICS channel

Gerardo, Jordan, Richard, Patrick, Fil, Jonathan, Dave

A temporary vacuum gauge was connected to the h1vacly beckhoff terminal to monitor the CP1 regen over the coming weeks. In lui of adding this to the production h1vacly code, we chose instead to read the raw voltage from Beckhoff and serve this data on a temporary IOC.

I wrote pt100a_ioc.py which reads the raw voltage from the Beckhoff channel H0:VAC-LY_TERM_M14_CHAN2_IN_VOLTS. It reposts this value and then converts it to torr. These channels exported are:

H1:VAC-LY_Y5_PT100A_VOLTS

H1:VAC-LY_Y5_PT100A_PRESS_TORR

Jonathan setup a containerized IOC on the VMs to run this IOC.

We created H1EPICS_VACLY.ini to add these channels to the EDC. The DAQ+EDC was restarted at 16:21.

This work is in support of the CP1 regen work permit.
