6.Viewing Process Values and Changing Setpoint

6.1Introduction

For your convenience, the CN8-SW system provides several ways to view process variable and setpoint as described in 6.2 and 6.3.

Any operator whose login account is configured with the appropriate privilege can use the CN8-SW system to change a controllerÕs setpoint as described in 6.4. (Instructions for changing the setpoint using ramp and soak recipes are in Section 9.)

Some Omega controllers can use the single step Ramp to Setpoint function at times other than at startup. The CN8-SW system provides a method to start the timer on the ramp to setpoint as described in 6.5.
