SPM module template configuration

Deleting SPM module template function blocks

In some instances, it may be desirable to delete one or more of the function blocks from the control module. For example, if the PV is being used in a different control module (such as in a PID control module), then you may want to delete the PV function block from the SPM module. As another example, if the pressure transmitter is being used in a gauge pressure application, it may not be necessary to monitor the CV. You may delete any of the function blocks that is not needed.

After deleting unneeded function blocks, you must also do the following:
  1. Delete any alarms referencing the deleted function block(s).
  2. Modify the code in the CALC block. Right-click on the CALC block, and select Expression from the context menu. Follow the instructions in the code comments to delete sections of the code that reference the deleted function block(s).
Note

To use the operator faceplate with the control module, you must at a minimum keep either the AI1 or MEAN function blocks, and either the STDEV or CV function blocks.

Note

If any function blocks are deleted, the operator detail display will recognize this and automatically make the corresponding fields invisible.
