The DeltaV library includes module templates that you can copy and customize. When you copy a module template from the library, the module includes history collection. For each module or node parameter field, the history collection strategy determines how values are recorded and displayed, the sampling period, and so on. You do not have to set up history collection for modules that you copy from the library.
If you are copying a module from an area, you must hold down the CTRL key or the module will be moved rather than copied to the new location. If you are copying a module from the library, it is not necessary to hold down the CTRL key while dragging the module.
You can add additional history collection to the module if you wish. We will add history collection to the module that we create from scratch. Later, we will use the Process History View application to view the field value.
In naming the motor (MTR) templates, the following convention was used: the first digit after MTR is the number of outputs; the second is the number of inputs. Thus, MTR-11_ILOCK is for a motor with one output, one input, and interlocks.
