Often a need arises to display on a mimic some or all of the following OPC properties for an object or a group of objects.
Naturally, users add these OPC properties to mimic animation. This is not recommended as it may cause additional load onto the client as well as the server. Especially, if these OPC properties are for the Root object or a group with large number of objects in it.
Instead, the following approach needs to be taken:

Instead, the following approach needs to be taken:
- Create a logic program or a series of logic programs
- Set these logic programs to execute every 5 seconds or so
- create an internal point or a variable (if the point count matters) for each OPC property
- In the logic program (s), map the actual OPC properties to their respective internal points or variables and use these internal points or variables in mimic animations.
