The main function of this module is the reflection of the data of the "Data acquisition" subsystem of the remote OpenSCADA stations on the local ones. In its work, the module uses the self protocol of the OpenSCADA system (SelfSystem) and service functions of the subsystem "Data acquisition".

The module realizes following functions:

Using of the available redundancy schemes is graphically represented in Figure 1.

From this tab you can set:

2. Parameters

The module though provides the ability to create the parameters manually, but it does not make sense as a parameter in absence it on the server will be empty. All parameters are created automatically, taking into account the list of reflected controllers and parameters. The parameters can be stored into the cache for following its creation even on link to the server miss. Example of the reflected parameter is shown in Fig. 3.
