Appendix C: ANASOFT-RS
This appendix explains the Ramp/Soak (r/s) feature of ANASOFT. Use
the ANASOFT User’s Guide as the reference to the standard functions
of ANASOFT. For a complete description of the ramp and soak profile
and cycle operation, see Watlow-Anafaze Controller Hardware
Installation and Operating Manual.
What is Ramp/Soak?
The r/s feature turns your controller into a powerful and flexible batch
controller. You can program your controller to change a process’
setpoint in a preset pattern over time. This pattern, or temperature
profile, consists of several segments. During a segment, the
temperature goes from the previous segment’s setpoint to the current
segment’s setpoint.
•
If the current segment’s setpoint is larger or smaller than the previ-
ous segment’s setpoint, it’s a ramp segment.
•
If the current segment’s setpoint is the same as the previous seg-
ment’s setpoint, it’s a soak segment.
Each segment can have up to two triggers which are digital inputs
assigned to the segment. At least one of these triggers must be true
before the segment can start. While the input isn’t true, the profile waits
(Trigger wait state). You can use the same trigger for more than one
loop or one profile.
Each segment can also have up to four events which are digital outputs.
The events occur at the end of the segment.
