Here are the details to use the TaskManager.
1. Initialize the task manager.
Three arguments are: the max tasks you can run in a same time; How long did the next send message call happens(milliseconds); and you should keep the connection when a single message called complete.

2. Add the addresses that you want to communicate to PLC. Area are defined in AddressTranslator in each type of communiction.
Basically you can write only Id, Area, Address, CommunicationTag, DataType and Zoom, and it should work. And there are other fields that you can use.

4. Implement ReturnValues event.
The argument return values is a key value pair. The architechture is:
Key : the link address of machine (in sample is the second parameter).<p>
Value : Dictionary.<p>
----------Key : CommunicationTag in AddressUnit.<p>
----------Value : ReturnUnit.<p>
