Why has no one thought about this before?  How week-long commissioning times at the customer’s location can be reduced to a few days<\/STRONG><\/P><\/p>\n

\u201cWhy has no one thought about this before?\u201d is one of the most common rhetorical questions in the commissioning of complex industrial plants. Large scale systems can deliver great results if the software that is controlling them is written cleverly and without failures.  Using sophisticated programmable logic controller (PLC) logic, with smart algorithms and clever case distinctions, can easily double the plant capacity. On the other hand, if the PLC software is based only on simple loops of copied and pasted processing it is often slow and the entire system has to contend with the nominal power.<\/P><\/p>\n

How can really good, stable control software for large complex production facilities be created and tested before the system itself is built? Can control software that uses the amounts of data from numerous sensors and thus increase the system performance?<\/P><\/p>\n

The answer is virtual commissioning. A computer model of the plant is created instead of the real system. This virtual image enables users to test controls and to improve PLC without physically moving material, without consuming energy, without creating noise and waste, to normal working hours and not into production breaks at night and on weekends. Best of all, it allows stress tests in the office, with the experts the company together without play updates on site at the customer at the last minute and to troubleshoot.<\/P><\/p>\n

How does virtual commissioning work technically?<\/STRONG><\/P><\/p>\n

A complete production facility is modeled in Siemens PLM software Tecnomatix Plant Simulation<\/A><\/SPAN><\/P><\/p>\n

Sensors are created and named according to the real sensors using the OPC interface the simulation model with the Siemens TIA portal. In the TIA portal the real PLC code is developed. This video, \u201cVirtual Commissioning on Factory Level<\/A>,\u201d by Ralf Tobel, R & D Director, Tecnomatix Plant Simulation describes the process.<\/P><\/p>\n

Now, two cases are possible: Hardware in the loop and Software in the loop:<\/STRONG><\/P><\/p>\n

With Hardware in the loop,<\/STRONG> the real physical PLCs are connected with the simulation model e.g. using PROFINET \u2013For an example, view \u201cSiemens virtual commissioning portfolio<\/A><\/SPAN>,\u201d video. Now the real PLC that will control the system later to the simulation model controls the simulation model. Special situations can be played through and analyzed like in a flight Simulator. These include, for example, the discharging of parts, overheating at sensors, lack of parts and smooth filing of gaps via PLC Control logic.<\/P><\/p>\n

With the Software in the loop, no real PLCs are used, but PLC emulating software. The PLC code does 1:1 the code of which the system will control later. With this technology the complete system can be run on one PC  in which the production is modeled, simulated, visualized, analyzed and optimized without cable to connect  or hardware to be wired.<\/P><\/p>\n

What is the benefit?<\/STRONG><\/P><\/p>\n

The virtual commissioning is not new but it is booming at the moment because of numerous Industrie 4.0 projects and is increasingly becoming a core technology. So reports the head of electrical engineering at Grenzebach Group. This video, \u201cTecnomatix Plant Simulation saves assembly time<\/A><\/SPAN>,\u201d explains how they are achieving multi-week savings in operating per each project.<\/P><\/p>\n

Another highly interesting case is described by Mr. Johannes Roeck from Siemens AG in \u201dSiemens – your partner for the entire battery manufacturing process.\u201d<\/A><\/SPAN><\/P>

Modern lithium ion batteries are the key to the success of electric vehicles. Siemens supports the complete value chain from raw material extraction to testing the finished cells. The virtual commissioning of the lithium ion battery cells production reduces costs and increases profitability.<\/P><\/p>\n

What are the restrictions?<\/STRONG><\/P><\/p>\n

Layout, size and complexity of the explored facility are nearly unlimited: the company Eisenmann<\/A><\/SPAN>, for example, installed at the airport in Doha a 1.6 km long electrified monorail system with 130 trolleys and roughly 20,000 transports per day.<\/P><\/p>\n

\u201cUsing the joint work of the control programmer with the simulation expert who configured and used Plant Simulation, we created a virtual commissioning setup, in which we were able to identify and solve real problems of our routing strategy control program.\u201d<\/EM><\/P><\/p>\n

\u201c Connecting Plant Simulation to the MFC, we were able to conduct some of this testing virtually, in the office. That\u2019s another project first. More importantly, this means that the real commissioning effort was smaller. Because real onsite commissioning is expensive, this capability has the potential to greatly impact the competitiveness of our offering in terms of cost.\u201d<\/EM><\/P><\/p>\n
