Automatic Program Operation - 73 - FDC MCT-MC
6.3 Monitoring Automated Ramp/Soak Program Operation
The program Status view provides all information regarding the operation of a program for each control loop
configured in the system.
The
Status field indicates the current operating mode of the program, i.e., On, In Hold and Off.
The
Cycles field indicates the number of cycles left to be completed for the current jump loop.
The
Steps field indicates the total number of steps in the current program.
The
Step field indicates the step number currently being executed.
The
Time field indicates the total length of time programmed for the current step.
Time Remaining is the time remaining in the current step.
The loop
SP indicates the programmed set point for the loop that will be achieved by the end of the step. The
field will indicate the current ramp or soak status for the loop based on the set point of the step. If the target
set point of the step is greater than the loop set point, “ramp up to” will be displayed. If the set point is lower
than the current loop set point, “ramping down to” will be displayed. If the step is a soak step or the target set
point is the same as the current loop set point, “soak at” will be displayed.
The loop
PV displays the current process value of the loop.
The name of the running program, or current program loaded to the loop control, will be shown at the bottom
center of the screen. If no program has been loaded, the field will be empty.
IMPORTANT: If the set point does not match the set point programmed for the step, check the lower and
upper set point limits for the loop (see Section 9.3 Setpoint Limits). The lower and upper limits
define the allowed operating range. If a step set point exceeds a limit, it will be coerced to the
lower or upper limit that it exceeds. This is done automatically without altering the original
program.
