WP8563 Add four 256Hz PSL FSS fast channels to DAQ

Rick, Camilla, Dave:

The H1PSLFSS.ini file was hand edited to uncomment the four requested channels and set their data rates to 256Hz.

The new DAQ was loaded onto h1pslfss at 08:05 PDT by pressing the "DAQ LOAD" button on the GDS-TP MEDM.

At the next optimum time, the DAQ data concentrator was restarted (08:06 PDT). This did not go well, monit on h1dc0 did not restart the daqd process. I logged into h1dc0 as root, stopped and then started monit, which in turn started daqd. This meant the DAQ was down for an additional 2 minutes than expected.

I ran my new script to restart all the FOM plots which are NDS clients (ndscope and DTT).

To verify the new channels have been added:

on the PSLFSS GDS_TP MEDM the number of fast channels increased from 4 to 8, the DAQ data rate increased from 293 to 297 kB (+4 because 1024 single prec float data points added per second)

I ran ndscope to view the 4 new channels.

TJ confirms the FOMS are back up and running. I'll add an MEDM button to run my restart script.
