Basic Principles of Data Transmission Technology 1. Characteristic Impedance and Delay Characteristics Ideally, due to the in-phase relationship between the voltage and current of the resistive components, the input signal experiences no phase shift when passing through the resistive network, only inherent attenuation. In practical circuits, since cables do not possess purely resistive characteristics but … Read more
PROFIBUS (Process Field Bus) is the iconic protocol in the field of industrial fieldbus communication, fundamentally changing the way communication occurs in traditional industrial environments. This article will delve into this important industrial communication technology, helping readers gain a comprehensive understanding of the working principles and practical applications of PROFIBUS. The Past and Present of … Read more
In the last issue, we mainly introduced the definition of Profibus DP, the core content of its three different versions, and the differences in their applications. This time, we will share the differences between Profibus DP and Profibus PA. Three Types There are three compatible versions of Profibus: Profibus-DP Profibus-PA Profibus-FMS Of course, in an … Read more

PROFIBUS Connectors and Termination Resistors The connectors are used to connect the PROFIBUS cable to the PROFIBUS stations (as shown in Figure 1). Figure 1 Use of PROFIBUS Connectors On the PROFIBUS connector, there is an incoming port (In) and an outgoing port (Out), which connect to the previous and next stations respectively. 1. Each … Read more
(1) Overview of PROFIBUS PA Bus PROFIBUS is the abbreviation for “Process FieldBus”, which officially became the international standard for fieldbus in 1989. It currently dominates various automation fields and consists of three parts: PROFIBUS DP PROFIBUS PA PROFIBUS FMS PROFIBUS PA is suitable for process automation design, applying intrinsically safe transmission technology (Manchester coding, … Read more
Profibus Wiring Whether forming an MPI or a PROFIBUS-DP network, the main components used are the same: PROFIBUS cable: There are various cable models, among which the most basic is the PROFIBUS FC (Fast Connect) standard cable (order number 6XV1 830-0EH10). PROFIBUS network connectors: There are also various forms of network connectors, such as different … Read more
