Siemens Announces a New Line of Compact, Flexible Profinet Switches for Process Automation
Siemens offers Scalance XF-200BA, a new line of compact switches. The flexible use of various bus adapters allows users to set up electrical and optical line, star, and ring structures. Bus adapters are available with RJ45, SCRJ and LC connection systems. Two types of switches are available: Scalance XF204-2BA, a standard switch for universal, cross-industry use, and the Scalance XF204 2BA DNA Y-switch for special tasks in process automation. An extended temperature range from 40 to +70° C together with approval for use in hazardous areas (ATEX Zone 2, IECEx) allow reliable use, even in harsh environments.
Both versions support up to four ports and various firmware-functionalities. For example, virtual LANs (VLANs) divide the physical network into several virtual sections to minimize the number of broadcasts in the network. Redundancy protocols, such as Highspeed Redundancy Protocol (HRP) and Media Redundancy Protocol (MRP), permit a high availability of machines and plants: If the communication fails, there is a switchover to the redundant path within milliseconds.
Additional functions, such as Link Aggregation and Remote Network Monitoring (RMON), round out the firmware range of the Scalance XF-200BA line of products. The switches are characterized by a compact enclosure that was developed following the design of the Simatic ET 200SP HA. As well as mounting on a wall or a standard rail, the Scalance XF-200BA is ideal for mounting in a control cabinet alongside the new Simatic ET 200SP HA. Siemens is exhibiting the new product line, together with the new version of the Simatic PCS 7 V9 process control system, at the Hannover Messe 2017.
The Simatic ET 200SP HA I/O system enables optimal use to be made of the properties of Profinet. The remote I/O line is specially designed for the process industry, is highly available, and can be used directly in the field, up to and including Ex-Zone 2. The Simatic Compact Field Unit (CFU) is a field distributor connected via Profinet and combines easy handling of familiar 4 to 20 mA technology with the advantages of digital field technology. The Industrial Ethernet/Profibus(IE/PB)-LINK PNIO provides an additional gateway for connecting a Profibus DP slave to a Profinet controller. One great advantage is the flexible use of the bus adapters with all the products mentioned. The user can rely on many automation and network components having the same design, technical setup, and mounting options.
All these components are networked with the Scalance XF204-2BA and XF204-2BA DNA switches, which are equipped with coated printed-circuit boards (Conformal Coating). They also meet the requirements of NAMUR/NE21, which specifies the immunity requirements for process and laboratory control equipment. The Scalance XF204-2BA DNA also offers Y-switch functionality for connecting S2 devices to a high availability R1 system.
As well as the two Y-switch ports, two other switch ports are available. With their aid, the S2 devices are connected to Scalance XF204-2BA DNA via a redundant ring. A five-year warranty applies to the new Scalance XF-200BA switches, as for all Scalance products.
Siemens Offers New Firmware for Performance Enhancement of Advanced Controllers for Automation
The new firmware 2.1 for the Simatic S7-1500 Advanced Controller from Siemens now allows the user to use the new functions of the Engineering Framework TIA Portal V14 SP1. These include openness to other systems, such as the standardized, bi-directional exchange of engineering data via AutomationML (Automation Markup Language) with Eplan engineering software, the TIA Selection Tool or other CAE (Computer Aided Engineering) tools.
The two fail-safe 1511TF-1 PN and 1515TF-2 PN technology CPUs are new additions to the portfolio of the Simatic S7-1500 Advanced Controller. The fail-safe Simatic S7-1500 T-CPUs from Siemens combine extended motion control functionalities, such as gearing and camming, with safety-related applications in a single device. Together with the already existing, fail-safe 1517TF-3 PN/DP T-CPU, which is used for more complex applications, they complete the portfolio of technology CPUs. The Simatic S7-1500 Advanced Controller has a functionally and fully scalable portfolio available to the user for standard, safety and motion control tasks.
The Simatic S7-1500 T-CPUs are specifically matched with Sinamics V90 PN and Sinamics S210 servo drive systems for mid-range motion control applications: The new Sinamics S210 servo drive system is available in five performance classes ranging from 50 to 750 watts. The many possible motion control applications focus on dynamic movement and processing – such as positioning, conveying and winding. The fully scalable motion control solutions can be implemented efficiently in the Engineering Framework TIA Portal with technology objects, integrated diagnostics and detailed error detection.
The new PS 60W 24/48/60 V DC HF power supply module for the Simatic S7-1500 Advanced Controller buffers the energy in the event of power failures. Without a battery and therefore maintenance-free, the new power supply module offers full data remanence of up to 20 megabytes for the CPUs. It feeds directly into the backplane bus and supports the integrated diagnostic modules of the S7-1500 system – for standard, safety and motion control applications. This speeds up the restart of machines and plants, as the data is still there when the power returns, and the parameters do not need to be reset. The new power supply module now also allows production applications for which the Simatic S7-400 was previously used to be converted to up-to-date Simatic S7-1500 technology with no limitation of the remanence behavior.
