We are testing a new version of the TwinCAT EPICS Ioc in the corner.

To revert: remote desktop into h1ecatc1. Close the IOC (running in a poweshell window). Start a new one using the "Restart EPICS database" button in the "LIGO TwinCAT Target Configuration" app.

To restart: Make sure the old IOC is gone. Go into C:\SlowControls\Target\H1ECATC1, right click on "start_tcioc_2_0.ps1" and select "Run with PowerShell". ("start_tcioc.ps1" is for the old code)

Version 2.0

Added features:

• Updated to Visual Studio Community Edition 2017
• Updated to EPICS base-3.15.6
• Updated to expat version 2.6.6
