ModesDeltaV Modes include:

Manual (MAN) — The output is set by the operator.

Automatic (AUTO) — The setpoint is adjusted by an external source and the loop calculates the output based on the algorithm.

Cascade (CAS) — The setpoint is adjusted by another function block through the Cascade input parameter and the loop calculates the output based on the algorithm.

Initialize Manual (IMAN) — The block output is being set in response to the back-calculation input parameter status. For example, when the secondary loop is not in Cascade, the primary loop goes to IMAN to prevent windup.

Out of Service (OOS) — The block does not perform the algorithm. The status is set to bad.

FISHER-ROSEMOUNT SYSTEMS DeltaV Regulatory ControlCourse 7009 - Rev 3 - 4/15/01

Modes Remote Cascade (RCAS) - Similar to Cascade except that the setpoint is

supplied by an external control program through the RCAS_IN parameter.

Remote Out (ROUT) - Similar to Manual except that the OUT value is supplied by an external control program rather than directly by the operator. OUT is supplied through the ROUT_IN parameter.

Local Override (LO) - The block is put into this mode when tracking is activated. When tracking is deactivated, the block returns to its target mode.

Note: IMAN = 2MAN = 8.0CAS = 48.0 (Target); 32.0 (Actual)AUTO = 16.0OOS = 1.0RCAS = 80.0ROUT = 144.0LO = 4.0

Mode Fields

DeltaV Mode Fields include:

Target - Mode is requested by the operator. Only modes from the permitted list may be requested.

Actual - This is the block’s current mode. This may differ from the target based on operating conditions.

Normal - This is the mode the block should be set to during normal operating conditions. May be configured and read but is not used by the block algorithm.

Permitted - List of valid mode choices.

Workshop -Creating a Regulatory Loop

This workshop requires you to perform the following tasks:

Task 1. Configure the regulatory loop FIC-102 using the PID_LOOPmodule template.

Task 2. Display loop parameters using Datalinks.

Task 3. Display PipesAnim Dynamos.

Workshop -Using the PID_LOOP Template

Create Regulatory Control module FIC-102 in the following manner:

Step 1. From the DeltaV Explorer, drag ‘n drop the PID_LOOP template from the Library to PLANT_AREA_A.

Step 2. Rename the module FIC-102.

Step 3. Launch the Control Studio and modify the module as indicated below:

Workshop -Modifying the Operator Display

Modify the operator display by adding Regulatory Control module FIC-102 to the Tank101 display in the following manner:

Step 1. Launch the DeltaV Operate (Configure) application and open the Tank101 display.

Step 2. Add Datalinks with the following characteristics:

FIC-102/PID1/SP

FIC-102/PID1/PV

FIC-102/PID1/OUT

FIC-102/PID1/MODE.A_TARGET

FIC-102/PID1/MODE.A_ACTUAL

Step 4. Animate the Valve color:

MTR-102 is RUNNING AND XVSTAT-101 is OPEN

1 - True YELLOW 0 - False GREEN

Step 5. Animate the Actuator color:

FIC-102 is OPEN

1 - True YELLOW 0 - False GREEN

Step 6. Connect the TANK, PUMP and VALVES together using PipesAnim.

Step 7. Save the display.

Operating & Verifying

Verify the operation of Regulatory Control loop FIC-102 in the following manner:

Step 1. Run the DeltaV Operate application.

Step 2. Verify Regulatory Control loop FIC-102’s functionality by manipulating the SP.

Step 3. Open the detail picture for FIC-102 and adjust the tuning parameters.

Note: Open the real-time trend from FIC-102’s faceplate.

Uploading Parameter ChangesYou can change the parameter values in a module online, in a running controller, by using either Control Studio or DeltaV Operate (Run). As soon as you make one change to the module online, the database module and the online module no longer match. Uploading parameters record parameter changes in the database.
