Data exchange between the process stations

The process stations may exchange data (outside temperature, heating / cooling demands etc.) between each other over the network. No other hardware nor software components are necessary, the only condition is that the process stations must be “visible” for each other in the network. This includes data exchange between different sites over the Internet; however, necessary routing rules must be configured in the active network components. Please consult the IT administrator.

The number of variables has no physical limitation, however, it is recommended not to use more than about 20 variables per process station to keep the software simple and easy to understand.

It is not a good idea to configure communication between the process stations inside of the control loops, e.g. a sensor in one station and the controlled valve in another station. The problem is not the data transport delay, which is hundreds of milliseconds. It should be avoided to configure the control loops dependent on the functionality of the network.
