Ensures Ethernet in industrial automation architectures

Industrial communication is moving against proven standards

Ethernet, which has seen great success and received universal acceptance in corporate, university and offices, has begun to find its way into the more demanding industrial applications. Ethernet can more and more be found in mission critical networks used in creating smart, self-healing, power grid systems, intelligent transportation systems and railway control systems as well as process control and manufacturing automation systems used across multiple industrial sectors.

Industrial communication is moving against standard Ethernet

Today Standard Ethernet (IEEE 802.3) has become a proven standard, allowing you to implement powerful, integrated data networks that are "future-proof." From simple sensor connecting to plant-wide quality and productions data acquisition and transmission, our comprehensive TCN tool for industrial communications solutions allow efficient timing analysis of all application flows within your network or system.

Switched industrial Ethernet is the backbone of efficient automation systems

Industrial data networks requirements in particular are extensive and constantly expanding. Switched industrial Ethernet is the established backbone technology to meet these needs. TCN's industrial Ethernet tools provide outstanding functionality and flexibility and can accommodate your changing requirements. The customers of TCN want to get answers to questions like this:

  • "This sensor value must reach my control algorithm host within 5 ms. Can the network forwarding delay of this frame ever exceed the deadline if I give this application data flow a priority of 2?"
  • "If this active link to this part of the network is broken, will the RSTP algorithm be able to re-establish packet forwarding using redundant links within 10 milliseconds?"
  • "My VoIP application should have a jitter less than 50 milliseconds for optimal user experience. Is that always the case?"
  • "Is there a risk that an I-frame in my MPEG-flow will ever suffer from packet drop?"
  • "How many cameras can I add to the network before response times goes down below the sharp dead-lines of other applications?"

What makes an Ethernet switch industrial?

As Ethernet moves from the office to the factory floor, you want to have equipment that works in your hot and dusty factory, not only in the comfort of the office. In fact, a whole new industry has sprung to provide Ethernet products that are designed for and tested to work under extreme conditions. The typical factory environment could be hot, humid, dusty and oily. Extreme conditions are also found outdoors, with huge temperature shifts, such as -30oC to +50oC.

Determinism is important for industrial communication

Up until now distributed real time systems have usually been based on field buses, but switched Ethernet is now an option. This is partly due to features such as: bandwidth, possibility of prioritisation and industrial specification of network equipment. However, also because Ethernet equipment prices have dropped.

Variable delay (latency) in a switched network means that data sent from nodes can be affected by different delays. This is due, among others, to the current load on the network. Variable network delay depends on: network load, speed, packet size and the topology used.

When using equipment in real time applications you may use different degrees of prioritization that guarantee the transfer of prioritized data. However, if one is capable to calculate worst case response time for all Ethernet flows this imply an even higher level of determinism for lower prioritized flows. In addition, it opens up for the possibility to not using the switch prioritization feature at all.

Time Critical Networks product offering

Time Critical Networks aims at a breakthrough in the area of system timing management of industrial automation and communication, by using a common, standardised approach for handling all timing-related information during the development process of Ethernet networks. The complexity, and the cost, of the development cycle is significantly reduced, while reliability is improved.


TCN Real-time Modelling & Verification Suite allows the network designer to construct a network topology using modelled switches and hosts, populate it with modelled flows, configure the switches with, e. g., different port priorities and link speeds and then assure himself that all requirements are met by letting the tool compute upper bounds on the latencies and jitter that each flow frame can experience. The tool allows easy exploration of a range of different what-if scenarios and identification of worst-case situations and thereby allowing the designer to minimize network resources while still being confident that every application will work as expected.

Unlike other solutions, which require costly installation of agents and probes on every LAN link, TCN Real-time Modelling & Verification Suite allow you to analyze and optimize a complete system or network, considering all necessary parameters to be able to guarantee latencies, jitter and no packet-drops in the switches.

TCN Real-time Modelling & Verification Suite give you the possibility to verify the simulated calculations against real physical measurements.
