Mathcad-HotRod2a2bc.pdf Calculations to compute the model for the hot rod system and for the gains.
HotRod.pdf              Hotrod.rss printed out in .pdf format.
HotRod 100 to 350.bmp	A picture of the RS500 trend showing a transistion from 100 to 350 degrees.
HotRod 350 to 100.bmp	A picture of the RS500 trend showing a transisition from 350 to 100 degrees. 
HotRod OSC.bmp		A picture of the RS500 trend showing how the simulated Hot Rod oscillate just
			like the real hotrod when the gain is set to 327.67
The Real HotRod response.jpg	A RS500 trend showing the response of the real Hot Rod.
HotRod RG bit on.jpg	A RS500 trend showing the response using when the RG bit is set.  Notice the
			output overshoots and oscillates more causing the PV to do the same.
HotRod picture.jpg	What the real HotRod looks like.
HotRod RG bit off.jpg	The trend shows the response when the RG bit is off.  Compare this to when
			the RG bit is on.   Both trends were using the same gains.
Real HotRod response with calculated gains.jpg
			This trend shows how the gains calculated using Mathcad worked on the real HotRod.
HotRod with Kc at 327.67.jpg
			This trend shows hot the real HotRod oscillates when only Kc is used and it is
			set to 327.67.  Compare with HotRod OSC.bmp above which is the simulated HotRod's
			response.
SLC AtoD scaling.jpg	Ron Beaufort's example of scaling the inputs for a SLC.
HotRod-PID-ML.RSS	A MicroLogix program showing how to control temperature systems using a PID.  The
			HotRod system is simulated.
HotRod-pid-ff-ml.jpg	A MicroLogix program show how to control a temperature system using only the P gain
			and feed forwards.
HotRod-PID-ML.pdf	A .pdf printout of the HotRod-PID-ML.RSS.
HotRod-pid-ff-ml.pdf	A .pdf printout of the HotRod-pid-ff-ml.RSS
petera.dbf		A data base file with data showing how the real HotRod's PV reacts to changes
			in the CV.  This data was provide by Ron Beaufort.
petera.bmp		A image generated using the petera.dbf data from above.
HotRod 100 to 350 10 sec loop.bmp
			A trend image showing how slowing the loop update time to 10 seconds adversely
			affects the PID control.
HotRod-pid-SLC.RSS	A SLC version of the HotRod-PID-ML.RSS program
