ENERGy

Online Demos are available !

Animated software demonstrations show how ENERGy Software works.

Text balloons and notes explain the different actions.

 
To discover some of the concepts implemented in ENERGy, please have a look to the following scenarios.

Operator console and monitoring concepts

An animation presenting the operator console (interfaces, capacities, etc) and some monitoring concepts is available here.

Make your system evolve : services creation / modification

In this animation, we consider that the operator has designed and represented the managed system with the ENERGy console.

However, in many cases, new needs will appear (new services to monitor for example) and operators have to make changes to their system.

The following animation shows how to create low level and high level service and make your system evolve.

SLS Exchange

A Service Level Agreement (SLA) is a formal negotiated agreement between two parties. It is a contract that exists between customers and their service provider, or between service providers. It records the common understanding about services, priorities, responsibilities, guarantees, etc. the main purpose being to agree on the level of service. For example, it may specify the levels of availability, serviceability, performance, operation or other attributes of the service, like billing and even penalties in the case of violation of the SLA.

A Service Level Specification (SLS) is a subset of an SLA and describes the technical characteristics of the SLA.

The following animation shows how an SLS is automatically exchanged between the ENERGy management system and a Network Provider, in case of resource shortage and following the policies defined by the operator.

Industrial automation on a public access network

Click here to download the Powerpoint presentation available for this description (please extract into one folder then!).

We are currently running an automation process over a public access network. A simple control process running with PROFINET is used for this (cf. slide 3). The PROFINET networks are connected to industrial gateways (IGW), which have access to two different public access networks (Operator 1, Operator 2). The gateways make for a transparent connection between the PROFINET networks on both sides, resulting in one logical network.

The IGW are managed by OpenMaster, which takes into account information from the IGWs and from the operator's networks in order to configure the best connection.

OpenMaster has to configure the virtual connection between the IGWs, so the connection is not interrupted. An interruption of the network results in a stop of the industrial process.

We set up an example industrial process. The example consists of a fluid mixing machine, where three tanks are connected. On slide 5 you can find a video of the working of the fluid mixing machine (click on the right picture to start it). It illustrates a batch process for bottling liquids. The two "upper" tanks containing different liquids are equipped with an adjustable level control. The third "lower" tank is filled from the upper tanks in a concentration ratio and a charge volume defined by the operator. There, the fluids are mixed. When the mixing has finished, the content of the third tank is bottled.

When the connection between the IGWs breaks, the industrial process breaks. There are different ways how this can happen. One example of it can be seen on slide 7 (again, click on the video on the right side to start it). In this example, while filling the third tank, the connection breaks. On the left-hand side, this is shown with the color red in the batch control on the operator screen. The third tank is filled, until its overflow security mechanism makes sure that the tank does not break. Only after the connection is re-established (red blocks turn to green again on the left-hand side), the process continues. Thus, the third tank will be emptied.
