Siemens Safety Evaluation Tool nu ook offline beschikbaar!

Met de TIA Selection Tool kun je zonder uitgebreide kennis van het Siemens producten portfolio, de voor een machine of productielijn benodigde producten eenvoudig selecteren. 

Configureer een compleet project met slechts een paar muisklikken - zonder handleiding, zonder speciale kennis. De gerealiseerde hardware configuratie kan worden geëxporteerd naar het TIA Portal en/of andere systemen. De TIA Selection Tool kan worden gebruikt als cloud-variant, maar kan ook worden gedownload als desktopversie. In de cloud-variant is het mogelijk om de projectconfiguratie met meerdere mensen in een team op te zetten.

Berekening PL/SIL

Na de keuze van de hardware componenten van een besturingstechnische veiligheidsfuncties dient de ontwerper ook aan te tonen dat de gerealiseerde veiligheidsfunctie voldoet aan het vereiste veiligheidsniveau. Daarbij kan de bekende Siemens Safety Evaluation Tool (SET) worden gebruikt. Met de Safety Evaluation Tool (SET) kan je voor besturingstechnische veiligheidsfuncties van machines het Performance Level (PL) volgens de EN-ISO 13849-1:2016 of het Safety Integrity Level (SIL) volgens de EN-IEC 62061:2015 berekenen.

Eén softwareplatform

Het handige van de integratie van de Safety Evaluation in de Siemens TIA Selection Tool is dat nu alles in één softwareplatform gebeurt. Dus als je bezig bent met het selecteren van de producten voor je productielijn en de veiligheidscomponenten, kun je ook de veiligheidsfuncties modelleren en direct het PL -en/of SIL-niveau doorrekenen. Daarnaast is het ook zo dat door de periodieke updates van de TIA Selection Tool, nu ook de Safety Evaluation automatisch in dit update traject mee gaat lopen. 

Producten van andere leveranciers

Het is ook mogelijk naast Siemens veiligheidsproducten ook producten van andere leveranciers aan de TIA Selection Tool toe te voegen. Op dit moment levert bijna elke leverancier van (veiligheids-)componenten de productspecificaties volgens het VDMA 66413 format. De VDMA is het Duitse Fachverband Verfahrenstechnische Maschinen und Apparate, dat enkele jaren geleden het dataformat  (de VDMA 66413 bibliotheek) voor componenten in veiligheidsfuncties heeft vastgelegd, zie de link: https://ea.vdma.org/66413bibo. Daarmee zijn ook de specificaties van componenten van andere fabrikanten te importeren in de TIA Selection Tool en te gebruiken in de berekening van de Safety Evaluation. De VDMA bibliotheek van de Siemens veiligheidscomponenten en -systemen is al standaard in de TIA Selection Tool opgenomen.

Voordelen

Het grote voordeel van de integratie van de Safety Evaluation in de TIA Selection Tool is dat alle informatie beschikbaar is in één platform. Vooralsnog zal de eerste release van de Safety Evaluation alleen in de offline-versie van de TIA Selection Tool beschikbaar zijn (Beta-versie). Later zal ook de online-versie beschikbaar komen. 

Een ander voordeel is dat door met de OFF-line TIA Selection Tool de berekeningen nu ook uitgevoerd kunnen worden op locaties waar geen toegang tot het internet beschikbaar is.

Siemens Safety Evaluation Tool now also offline avaliable!

Siemens has recently (June 2020) integrated its Safety Evaluation Tool (SET) into the Siemens TIA Selection Tool. With the SET, the Performance Level (PL) or the Safety Integrity Level (SIL) can be calculated off-line and in the cloud. 

With the TIA Selection Tool you can easily select the products required for a machine or production line without extensive knowledge of the Siemens product portfolio. Configure a complete project with just a few mouse clicks - without manual, without special knowledge. The realized hardware configuration can be exported to the TIA Portal and/or other systems. The TIA Selection Tool can be used as a cloud version, but can also be downloaded as a desktop version. In the cloud version it is possible to set up the project configuration with multiple people in a team.

Calculation PL/SIL

After selecting the hardware components of a control safety function, the designer must also demonstrate that the realised safety function meets the required safety level. The well-known Siemens Safety Evaluation Tool (SET) can be used for this purpose. The SET can be used to calculate the Performance Level (PL) for machine control safety functions according to EN-ISO 13849-1:2016 or the Safety Integrity Level (SIL) according to EN-IEC 62061:2015.

One software platform

The advantage of the integration of the SET into the Siemens TIA Selection Tool is that now everything is done in one software platform. So when you are selecting the products for your production line and the safety components, you can also model the safety functions and directly calculate the PL and/or SIL level. In addition, due to the periodic updates of the TIA Selection Tool, the Safety Evaluation will now automatically be included in this update process.

Products from other suppliers

In addition to Siemens safety products, it is also possible to add products from other suppliers to the TIA Selection Tool. Nowadays almost every supplier of (safety) components delivers the product specifications according to the VDMA 66413 format. The VDMA is the German Fachverband Verfahrenstechnische Maschinen und Apparate (Fachverband Verfahrenstechnische Maschinen und Apparate), which several years ago defined the data format (the VDMA 66413 library) for components in safety functions, see the link: https://ea.vdma.org/66413bibo. This allows the specifications of components from other manufacturers to be imported into the TIA Selection Tool and used in the calculation of the Safety Evaluation. The VDMA library of Siemens safety components and systems is already included as standard in the TIA Selection Tool.

Advantages of the tool

The major advantage of integrating the Safety Evaluation into the TIA Selection Tool is that all information is available in one platform. For the time being, the first release of the Safety Evaluation will only be available in the offline version of the TIA Selection Tool (Beta version, june 2020). Later, the online version will also become available.

Another advantage is that with the OFF-line TIA Selection Tool the calculations can now also be performed in locations where there is no internet access available.

PL and SIL; misconception number 1: "SIL is only for machines in the process industry."

Introduction:
Developments such as electronics and software for safety functions in the machine control system have led to fact that the standard EN 954-1 1996 no longer meet the requirements and will be withdrawn on December 31, 2011!

Therefore two new standards were established for the machinery sector. In the year 2005 the standard EN 62061 was adopted and one year later the EN-ISO 13849-1, respectively giving a classification of the safety level in a "Safety Integrity Level” (SIL) and a “performance level” (PL). Both standards are harmonised under the new Machinery Directive 2006/42/EC.

The misunderstanding:
A frequently heard statement from suppliers as well as consultants, "The SIL standard has its origins in the process industry and is primarily intended for companies who deliver machinery in the process industry." When you don’t deliver machines to the process industry, it is much more logical and better to apply the PL standard.

The reality:
The old EN 954 had no requirements for safety components made up of programmable logic. It refers users to the standard "IEC 1508”, which in 2000 was adopted as European standard EN 61508 (IEC 61508). This standard consists of seven parts and is very extensive (740 pages).

The EN 61508 is written by people from various industries and should be seen as a "basic safety publication". This means that this standard can be used by IEC technical committees to create their own industry sector standard or product standard. See also a useful book [1] from IEC about the purpose of this standard.

The standard EN 62061 (IEC 62061) is derived from the EN 61508 and the IEC standard committee TC44/WG7; safe control systems for machinery made it an industry sector standard [2]. The EN 62061 is specially developed for the machine industry! This committee consists of several experts in the field of control technology, ranging from product suppliers and consultants to notified bodies.

In addition, the process industry since 2003 has their own derivative, called IEC 61511. The figure below shows that in various industries a specific “SIL sector standard” is created already.

In short, EN 62061 is specifically developed for the machine industry!
