Loading the Controls through the ICC

The process of loading controls in a SCP is exactly the same as the real CP. The system definition of a plant can be used as-is and the contents of each real CP are downloaded to the corresponding SCP.

If running in standalone mode, the checkpoint file is valid. If using an SCP Engine connected to the DSS infrastructure, once the modifications are complete, run the simulation in order for the changes to take effect. After completing a control configuration modification, and running the simulation through a cycle, perform a Checkpoint through the ICC.

Once the simulation is loaded and "Frozen," take the following steps to load controls using the ICC.

If a simulation is open and loaded, then put the simulation in FREEZE mode until the completion of the steps below.

1. Invoke the ICC.

2. Click Config in the main menu bar in FoxView. (It may be necessary to change the environment in order to access this menu option). From the pulldown menu, select Control_Cfg, and then select CIO_Config.

3. The ICC window displays with the Compound Selection window inside the ICC window. Click the Vol button at the bottom of the Compound Selection window.

4. The Compound Selection window is replaced with the Select Station Type to Edit window. Click Edit Station.

5. The Select Station Type to Edit window is replaced with the Select a Control Processor to Configure window. Select the name (letterbug) of the SCP.

6. Insert the SaveAll diskette into the WSTA diskette drive.

7. In the ICC window, click MAINT, and then Load All.

8. A prompt appears to select the device for the LoadAll procedure. It should automatically select the correct host name and diskette drive. Continue with the load by selecting DONE.

Error Logs

Error messages encountered during the loading process are written to a log file located on the WSTA at d:/opt/fox/ciocfg/ld< letterbug>.log, where < letterbug> is the letterbug ID of the SCP station (CP270/CP280. This file is overwritten, as each new diskette is inserted and loaded.

9. Repeat the previous step for each SaveAll diskette. For each subsequent diskette, the following dialog box displays on the ICC screen:

   

10. Click YES to continue the loading procedure.

11. Once the control configuration is loaded, the Compound Functions window displays. In order for the control changes to take effect, run the model for at least a few time steps.

12. After the control configuration load is complete, run the simulation, and then freeze it. The simulation should run through the longest period/phase of your controls. This duration can vary from 0.5 sec to 30 minutes. Typically, 10 seconds is sufficient.

13. Compile IND, MON, DEP, and EXC blocks. When complete, run, and then freeze the simulator.

14. Perform a CHECKPOINT through the ICC.

    Note: if a checkpoint is performed before each block and cycled through its period / phase, the block is undefined, cross referencing does not function, and the checkpoint is not valid.
