Example: Using an analog template for three containers

In a cement factory, there are three containers with mortar, sand and cement, respectively. The volume of the three containers is identical, namely 100 cubic meters. The containers should not hold more than 70 cubic meters. On the other hand, they should never be empty.

A common template will define the measuring of the contents of the three containers. All of the variables, such as the dynamic area, unit of measure, alarm limits, alarm number, etc. are the same for the three containers. The only information which is not the same, and therefore must be entered for each container, is the PLC address - the three containers contain different materials and, as a result, are measured/controlled from different PLC addresses.

After defining the template, the three objects which represent mortar, sand and cement are defined. The only additional information the system needs for each object is a unique name, the specific PLC address, and, if necessary, an explanatory text as well as graphical display.
