WP6451 Dave:

The cell phone text alert system was modified to:

1. restore the actual pump level for CP4

2. annotate the daily messages with the error status for each channel

I restored CP4 and its ERROR channel in the h0ve alarm configuration file.

I modified the epics_alarm_texter.py code so each daily text for cryopump and vacuum gauge status shows the corresponding ERROR status of each value. The ERROR status is a single character following the value:

SPACE means no error

"!" means error

"?" means error channel data unavailable

Today's vacuum gauge text is:

2.602e-09  1.907e-09  1.365e-09  1.624e-09  
2.434e-09  9.976e-10  1.203e-09  1.317e-09  

spaces following the numbers means no errors

Today's cryopump text is:

cp1=92.0  cp2=92.0  cp3=-1.0? cp4=0.0! 
cp5=92.0  cp6=92.0  cp7=92.0  cp8=92.1  

CP3 has a value -1.0? which means both the value and the error are unknown (this is currently not monitored by the system)

CP4 has a value of 0.0! which means we are receiving a value of 0.0 but the ERROR channel is asserted (4-20mA current below 4mA)
