What is a Profibus connector?

What is a Profibus connector?

The PROFIBUS DB9 connector is used in most IP 20 environments and is the best solution for high transmission speeds. The connector is perfect for establishing a connection between cables and to create the ideal branch. The majority of connectors have coils to suppress noise and reflections.

How does Profibus cable work?

The PROFIBUS DP network is a multi-master token network – that means when there are two or more masters in the system, a token giving the right to talk to the field devices is passed from master to master, and each gets a share of the communication time.

How do I terminate Profibus cables?

Termination Of Profibus Cables A Profibus termination is done by inserting a 220 Ω resistor in each end of the Profibus line. So, you insert a 220 Ω resistor in the first and one in the last station. The reason for using a 220 Ω resistor is that the two 220 Ω resistors are connected parallel to each other.

Is PROFIBUS still used?

While the transition to Industrial Ethernet is palpable on every level, no we are not done with PROFIBUS. In fact, it is still the main industrial communication protocol implemented in the Italian market.

What is the difference between Ethernet and PROFIBUS?

While Profibus cables may be up to 1000 meters long, shorter cable lengths are required for higher data rates. Profinet is a newer, Ethernet-based industrial communications protocol. Because Profinet uses the same physical connection standards as Ethernet, standard Ethernet switches can be used to expand your network.

Where does Profibus have to be terminated?

Therefore you must observe that PROFIBUS segments are only terminated at the two segment ends and nowhere else. Any additional terminations can cause corruption of the PROFIBUS signals and network malfunction.

What is the minimum length of cable between Profibus devices?

What is the minimum distance between 2 devices on PROFIBUS DP? When the transmission speed is 1,5 Mbps or higher, it is highly recommended to have at least 1 m of cable between 2 devices. De input capacitance of both devices will be compensated by the cable in order to preserve the common impedance.

Who uses PROFIBUS?

PROFIBUS PA (Process Automation) is used to monitor measuring equipment via a process control system in process automation applications. This variant is designed for use in explosion/hazardous areas (Ex-zone 0 and 1).

What is the difference between Ethernet and Profibus?

Which is better PROFINET or PROFIBUS?

PROFINET is one of the many industrial ethernet systems out there, which is often compared to PROFIBUS. Because it’s ethernet based, PROFINET can operate on a much higher transmission speed than PROFIBUS. With PROFINET, the cycle times are also adjustable for each device, whereas PROFIBUS has a fixed cycle time.

Is PROFINET serial communication?

In short: PROFIBUS is a classic serial Fieldbus, and PROFINET is an industrial Ethernet protocol. PROFIBUS and PROFINET are both IEC standards created by the same organization: PROFIBUS and PROFINET International.

How do I use the termination switch on a PROFIBUS connector?

Most Profibus connectors has a termination option. This means that you don’t have to connect your own resistor manually. You can activate or deactivate termination in the connector by flipping the switch, usually placed at the top of the connector. This is useful in two ways.

What is easyconn PB – PROFIBUS connector?

EasyConn PB – Profibus Connector with Diagnostic LEDs. The best-in-class PROFIBUS Connector EasyConn PB from profichip is used for the connection of Profibus participants to the bus line. It provides all test functions speeding up implementation and trouble shooting in an industrial environment.

Is the Profibus bus connector compatible with Siemens original part?

It is 100% compatible with Siemens original part. More profibus bus connectors we can offer as follows: Not made by Siemens,but the quality is 100% guaranteed,1 year warranty. All of our compatible products are tested one by one by our Engineer department before shipment.

What do the different colored connectors on a PROFIBUS cable mean?

Most Profibus connectors though has a green indicator for where channel A goes and a red indicator for where channel B goes. Using different colors or switching the green and red can cause a lot of confusion. Then we have pin 5 and pin 6. They are used for termination. More on termination of the cables later.
