Industrial Wireless Communications

Question 1

What is the range for a radio connection with DATAEAGLE?

Answer

Depending on the selection of DATAEAGLE radio systems, up to 3000 metres is possible with wireless data communication. With Bluetooth, a range of up to 1000 metres with a line of sight is possible. The 869 MHz and 915 MHz radio technologies are used for longer distances.

Question 2

What does Black Channel mean?

Answer

What does Black Channel mean?

The black channel principle allows the transmission of safe and non-safe process data over the same network or bus line. Regardless of the regular data transport mechanism used on this line, safety components can transmit data using an isolated safe protocol that tunnels through the underlying network channel. Since safe fieldbuses are pure application protocols without their own physical properties, the available bandwidths and cycle times depend on the data transport protocol used. Possible transmission errors are known and are listed in the relevant standards IEC 61784-3 and IEC 61508.

What does this mean for PROFIsafe?

The PROFIsafe protocol has no repercussions on the standard bus protocols. It is intended to be as independent as possible of the respective transmission channel, whether copper cable, fiber optic cable, backplane bus, or wireless. Neither the transmission rates nor the respective error detection plays a role. For PROFIsafe, the transmission channels are merely “black channels”.

Secure data transmission by radio: the black channel principle in detail

This means that the use of wireless technologies is also provided for and possible by definition, just like other radio technologies. Both the safety controller and the remote IO system – for example a safety switch – contain the safety protocol. The interface between them is merely the channel for transmitting the safety information. Accordingly, no safety certification is required for the wireless device and it is treated like other infrastructure components, such as switches or cables. This makes the recalculation or verification of the safety level (SISTEMA) for using a black channel solution obsolete.

Question 3

Can I replace my cable chain, optical transmission or slip rings with radio transmission?

Answer

Yes. With DATAEAGLE radio systems you can establish a reliable and stable radio connection. Flexibly adaptable production plants, multi-axis robot systems and decentrally operating machines place high demands on signal and data transmission. Wired solutions reach their limits when moving or rotating parts as well as mobile systems are to be integrated via PROFIBUS, PROFINET, PROFIsafe and other fieldbus protocols. Absolute reliability is just as important here as long service life and freedom from maintenance with wireless communication. Only a secure connection between controllers and IO modules ensures permanent availability of machines and plants without downtime.
