4.3.1.2.1 Ramp & Dwell:
Many applications need to vary temperature or process value with time. Such
applications need a controller which varies a set point as a function of time. This Process
Control Process Control Card can do this. The set point is varied by using a set point
profiler. The profile is stored as a series of “ramp” and “dwell “segments, as shown below.
Figure 4-59.Set Point Profile
In each segment you can define the state of up to 3 event outputs which can drive either
relay, logic or triac outputs, depending on the modules installed. A profile is executed either
once, repeated a set number of times or repeated continuously. If repeated a set number of
times, then the number of cycles must be specified as part of the profile.
