Daily monitoring of tiedowns.

• Digital plots  showing position,kips, and values of the digital bits (one plot for each tiedown) (more info)
  
• Analog plots : position, velocity,status, and torques (one plot for all 3 tiedowns) (more info)
  
• Cur : is the most recent date (usually the previous day since the script is run at 00:10 am each day.
• Cur_m1 : is 1 day before the Cur
• Cur_m2 : is 2 days before the Cur... etc...

Description of Digital plots:

• page 1
  
• top frame:tiedown position vs hour of day. black=td12,red=td4,green=td8
• bottom: tiedown kips vs hour of day.
  
• 2 loadcells per td.
  
• td12: black,red
• td4  : green,blue
• td8  : violet,pink
• page 2-8 digital bit values
• each digital value has a label to the left of the line
• If a - sign appears to the left of the label, then the label is true when the value is low
• eg
  
• Drv1Flt  .. drive 1 fault. Since no - sign, the faults is active when the value is hi
• -MampFdBk .. master amp foldback fault. Since a - sign, the fault is active when the value is low.
  
• The * by the label shows the location of the low value
• Page 2: device status
• Page 3: little star digital inputs
• Page 4: Universal I/O digital input 1 and 2.
• Page 5: Little start digital outputs
• Page 6: Drive and Fault status
• Page 7: torques for all 3 tiedowns:

Description of Analog plots:

• colors: black=td12, red=td4,green=td4
• Top: tiedown position vs hour of day.
  
• 2nd Frame: Velocity feedback of input to the amplifier.
• The pink color is the commanded velocity for 1td (def:td12)
• glitches can also be from interference at the input to the A/D (mainly from the amp).
• 3rd Frame: Amp speed monitor
• This comes from the speed monitor output from the amp.
• 4th Frame: drive status:
• 0:drive off, 2: drive powered, 1: drive enabled (it can move),  3: fault condition
  
• bottom frame: drive current (torque)
• this comes from the amp current/torque output.
