System Platform Mediator : Principle of the use of the mediator 🔒
The mediator for Application Server uses the MxAccess Object to make the link to the data of Application Server. By default, the mediator makes a link to the property “.InAlarm » for the management of the alarms. In such case, it also makes a link (on option) to the properties “.Acked” and “.AckMsg” for the synchronization of the alarm acknowledgement between Alert and Application Server.
It is also possible to create a link to a single variable and define an alarm from this variable in Alert. But in this case the alarm acknowledgements are not synchronizing between Alert and Application Server.
For the importation of the variables/alarms, the mediator uses the object GRAccess.
The mediator can be installed on the same computer than Application Server (on the GRNode) or on another computer.
If the mediator is not installed on the same computer, you first have to install a bootstrap on the computer where Alert (and the mediator) is installed and the computer must be defined in the galaxy. (See the documentation of Wonderware to know how to configure a remote access link).
