Monitoring and Controlling the
Loops
This chapter shows you how to monitor and control the PID loops.
This includes:
•
Loop Monitor screen
•
changing loop settings
•
Module Monitor screen
To monitor a loop of a particular module, at the Project screen, select
the module and loop; from the
Loop menu, select Monitor.
The Loop Monitor screen for the current loop appears.
The values on this screen are refreshed about once per second.
If the set-point ramp field:
Indicates:
Then:
No Ramp
setĆpoint ramping is disabled OR set point ramping is
enabled, but the set point is currently not ramping
Up
setĆpoint is increasing due to set point ramping
Down
set point is decreasing due to set point ramping
Holding
set point would be ramping, but the Ramp Hold bit is
set
Note: With Module Firmware versions prior to 3.3, this field will
display “No Ramp” when the set point is not ramping, and “Down”
when the set point is ramping, regardless of whether it is ramping up
or down.
