DAQ restart for Vacuum PT180 upgrade

Patrick, Jonathan, Dave:

PT180 (BSC8) was upgraded from a BPG402 to a BCG450. Patrick generated a new h0vaclx.ini file with the following changes:

MOD2 number of channels down by 2

MOD3,MOD4 added, each 7 channels

So net increase of +12 channels.

I created two new INI files, one for the standalone EDC (h1nds3) and one for the main DAQ.

I restarted h1nds3 at 12:30 PDT, the number of channels increased as expected and all channels connected correctly.

I restarted the main DAQat 12:38 PDT in the sequence: h1dc0 shutdown, followed a few seconds later by h1edc restart.

Monit had lost connection with the h1dc0 daqd process and did not restart it automatically. I manually instructed monit to restart using the web interface, and the DAQ came back after a downtime of several minutes.
