In this case the data is passed on from one data terminal to the next. Therefore, the entire ring is always under load. The advantage of the ring network is that it can cover a larger area than a star n etwork because the length of the transmission path is only ever the distance between two adjacent data terminals. This is the current standard for the majority of corporate data networks. Two wires are used for transmitting data and two for receiving. These cables are well shielded and can transmit data with frequencies of up to 500 MHz over distances of up to 100 m.

Decentralised units are, for example, controls, computers, measuring sensors, actuators, etc. One unit transmits the data, the second unit receives it. This corresponds to the simplest method of data transmission. It is often necessary for one unit to receive data and then send an “answer” back to the other unit. Two data lines in a back-to-back arrangement are required for this, or data lines are combined by providing each end of the data line with a transmitter and receiver. Structures and properties of networks There are various options for networking data terminals. We distinguish between star, ring, point-to-point and bus networks. Star networks The main unit is located in the centre. The individual data lines then radiate out from this centre to the individual terminals. In this system all data terminals are connected to the central terminal via their own cable. D.2 Point-to-point networks These are basically networks between two data terminals that are connected directly with each other, e.g. an RS 232 or RS 422 link. Bus networks These are networks based on the parallel connection of modules. All components operate on one and the same line. Therefore, only two/four wires are required for the data bus. If bus cabling includes branches, then we call that a tree structure. Every bus system includes a bus controller that issues “transmission licences” to the individual data terminals. Transmission media In order to be able to send any data at all, data lines are necessary: Coaxial cable Sending data via coaxial cables is a rather old technique. This method is too slow and inflexible and only a few businesses are still using such systems. Speeds of up to 12 Mbps are no longer adequate these days. Over longer distances, modern fibre-optic cables have been replacing this technology; these can transmit several hundred Mbps. Serial interfaces A serial interface operates with 8 data bits (1 byte). A start bit (low bit) is always sent before the output of a byte, and one or two stop bits (high bits) are appended to the end of the byte. This encryption is critical for the data receiver as it can then detect where each data byte begins and ends. Serial interfaces frequently operate with +5 V (logical 1) and 0 V (logical 0). Advantage: less cabling (only 3 wires). Disadvantage: slow data transmission. Two- and three-wire systems Data transmissions requiring relatively low transmission rates can make use of two-wire systems. For example, an ISDN system acting as an exchange line to a building requires only two wires. However, there are bus systems which also require only two or three wires. 2028840000 Lightning and surge protection for data interfaces Surge protection fundamentals for data signals RS 232 Serial interface for point-to-point connections up to 20 kbit/s Voltage signal to earth: logic 1 (mark) -15 V to -3 V logic 0 (space) +3 V to +15 V max. signal level ±15 V Lines up to 20 m long depending on transmission rate.

For their own protection, these need to be installed in central switchgear cabinets. However, decentralised solutions that do not require large switchgear cabinets are increasingly being sought for use in modern-day industrial automation technology. It is true that shielded signals can be fed to the machinery via powerful fieldbus systems; but in each case, however, there remains an interconnecting cable between the subdistribution boards and the sensors/actuators that is susceptible to interference from surrounding operations. As has always been the case, signals are still influenced by overvoltages and earth loops; interference pulses are superimposed on sensor signals and malfunctions can be initiated. The result is that signal conditioning modules sealed to IP20 require terminal boxes, such as switchgear cabinets, or even cost-intensive special solutions (for example, sensor-actuator distributors with integrated signal-conditioning functions providing as many functionalities as possible, even when these are surplus to requirements). By introducing JACKPAC®, the M12/RJ45 signal box for Ethernet Cat. 6 with a high-protection rating of IP67, Weidmüller now has a modular, versatile strategy that makes it possible to condition signals in an industrial environment. Requiring no additional enclosure, these modules can be installed directly on the machine, in the production plant, conveyor system or within a process. The M12 connector, which is standardised all over the world, makes it possible to integrate the JACKPAC® at any point in the sensor-actuator cabling. The fixed pin assignment means it is easy to install and is protected against polarity reversal. This versatility really comes into its own when an installation needs to be altered or modernised, simply because no additional enclosures or cabling are required. By providing this high degree of protection and versatility, JACKPAC® renders possible innovative automation concepts based on decentralised applications – without large control cabinets or small distribution boards – for consistent, transparent, efficient and cost-efficient installations.

Likewise, the transmission paths should also be kept as short as possible because the longer the line, the greater is the chance of interference having an effect. Inserting surge protection increases the attenuation of the line and so changes the signal-to-noise ratio. Installation position Protective modules are frequently installed at both ends of the line. It is important to ensure that protected and unprotected lines are routed separately. Further, there should be some clearance between power lines and data lines. A common cable duct must be subdivided with metal partitions. D Shielded lines for data interfaces Systems involving several buildings should be designed with cable shielding capable of carrying current. These data lines often have two shields: one for carrying transient currents, the other as protection against coupled interference. Circuit concepts High transmission frequencies place greater demands on surge protection in protective circuits for data interfaces. Gas discharge tubes are frequently the sole means of protection in these cases. However, the disadvantage of this is that the protection level is very high. Lower protection levels can be attained at high transmission frequencies by using special low-capacity suppressor diodes. 2028840000 D.21 D D.22 2028840000 Lightning and surge protection for data interfaces
