Industrial Ethernet Switches for reliable communication in automation

The Scalance XC-200 product line from Siemens is a new generation of compact Industrial Ethernet switches offering many functions, including the option of complete PROFINET or Ehternet/IP diagnostics in one device.  In addition, these managed switches are gigabit-capable, support VLAN and redundancy mechanisms, and thanks to their diverse certifications and flexibility they can be used for a wide range of applications, such as:  

• mechanical engineering
• transportation, including along rail-guided routes
• automotive, food & beverage, and oil & gas industries

 Advantages
  • Robust housing and extended temperature range (-40 °C to 70 °C)

  • Gigabit-capable and bridging of up to 200 km between two SCALANCE XC206-2SFP

  • Trackside railway approval (EN 50121-4) and approval for use in hazardous areas (ATEX Zone 2, IECEx)

  • Optional support of real-time communication via PROFINET or Ethernet/IP

  • Prevention of downtimes caused by contaminated or worn optical connections by means of Fiber Monitoring.

The Scalance XC-200 devices let you set up electrical and optical line, star and ring structures in industrial networks. 

They are available in different versions with up to 24 RJ45 ports and two ST/BFOC or two SC ports. With the Scalance XC206-2SFP, users can flexibly select two ports. Depending on what is needed, fiber-optic SFPs are used for single mode with a maximum range of 200 km or for multi mode with a range of up to 5 km. All of the devices are equipped with a redundant power supply. It enables reliable operation even if one power supply system fails. The robust housing and the collars combined with the FastConnect connectors and cables ensure stable RJ45 connections in environments in which equipment has to endure shock and vibration. Due to their design, user can mount the managed Industrial Ethernet switches on the wall, on a 35 mm DIN rail, or on a Simatic S7-1500 mounting rail. Clearly arranged diagnostic LEDs and a signaling contact enable precise determination of the state of the equipment as well as fast and reliable diagnostic evaluations.

Furthermore, integrated firmware functionalities increase the reliability of the network. For example, virtual LANs (VLANs) divide the physical network into several virtual sections and thus 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: When the communication fails, there is a switchover to the redundant path within 200 ms. It is also possible to couple several redundant rings with each other via HRP (standby master/slave).

The Fiber Monitoring function, which is integrated in all Scalance XC-200 with a fiber-optic connection, continuously monitors the fiber-optic cables. It warns the user when the cables become old or impure. This allows predictive maintenance and reduces plant downtimes. Additional functions such as Link Aggregation and Remote Network Monitoring (RMON) round out the firmware range of the Scalance XC-200 line of products.

A five-year warranty applies to the new Scalance XC-200 switches, as for all Scalance products.
