  • Maintenance and Decoding of Field Buses
    MAINTENANCE AND DECODING OF FIELD BUSES Today, most of the electrical appliances that we use include internal electronics. These circuits often need to communicate via data buses, either with ancillary systems, such Maintenance as remote sensors, or with control systems. This is particularly true in industry, where a single PLC remotely manages multiple sensors and actuators. Formerly, communication with these buses took place via an analogue signal using the “4-20 mA” network. This communication mode had many disadvantages, including Measurements the need for extensive equipment and complex wiring, thus increasing the time required for installation. For this reason, digital communication standards have been developed and are now widely used to avoid these problems. “Fieldbus” is a general term which corresponds to a method of communication between different systems. There are many standards: those specific to manufacturers Analysis and those standardized according to the equipment involved. Here are a few examples of fieldbuses used in different sectors of activity: Diagnostics The example of the automotive sector The new means of intra-system communication have allowed This provides numerous advantages: developments in the systems. The most obvious example is in the • less wiring automotive industry. In this sector, with the development of safety and • lower production costs due to savings on equipment analysis systems such as airbags, anti-lock braking systems (ABS) and • easier maintenance as there is only one communication channel electronic stability programs (ESP), the number of sensors and actuators on vehicles is constantly increasing. Each of these systems could be In addition, performance is improved because the linked directly to the vehicle’s computer via data buses, but this would data are available at all points on the require too much cable.

  • Efficiently Triggering, Debugging and Decoding Low-Speed Serial Buses
    Efficiently Triggering, Debugging and Decoding Low-Speed Serial Buses Hello, my name is Jerry Mark, I am a Product Marketing Engineer at Tektronix. The following presentation discusses aspects of embedded design techniques for “Efficiently Triggering, Debugging, and Decoding Low-Speed Serial Buses”. 1 Agenda Introduction – Parallel Interconnects – Transition from Parallel to Serial Buses – High-Speed versus Low-Speed Serial Data Buses Low-Speed Serial Data Buses – Challenges – Technology Reviews – Measurement Solutions Summary 2 In this presentation we will begin by taking a glance at the transition from parallel-to-serial data and the challenges this presents to engineers. Then we will briefly review some of the most widely used low-speed serial buses in industry today and some of their key characteristics. We will turn our attention to the key measurements on these buses. Subsequently, we will present by example how the low-speed serial solution from Tektronix addresses these challenges. 2 Parallel Interconnects Traditional way to connect digital devices used parallel buses Advantages – Simple point-to-point connections – All signals are transmitted in parallel, simultaneously – Easy to capture state of bus (if you have enough channels!) – Decoding the bus is relatively easy Disadvantages – Occupies a lot of circuit board space – All high-speed connections must be the same length – Many connections limit reliability – Connectors may be very large 3 Parallel buses present all of the bits in parallel, as shown in the logic analyzer display. A parallel connection between two ICs can be as simple as point-to-point circuit board traces for each of the data lines. If you can physically probe these lines, it is easy to display the bus state on a logic analyzer or mixed signal oscilloscope.
