3.4 TYPICAL BLOCK CONNECTIONS FOR RAMP/SOAK BLOCK
A typical Ramp/Soak Profile is used as the Remote Setpoint to the PID block. Whenever the
PID block Output Mode is not AUTO or the Setpoint Mode is LOCAL the PID block Track
Status is set TRUE. Therefore, the Ramp Soak block will go to the TRACKING state.
Connections between the Ramp Soak block and the PID block are shown in Figure 3-7.
