FAQ
Is a PROFIBUS radio connection stable?
Yes, for example, with an intelligent radio data transmission system such as DATAEAGLE, stable wireless communication between machines is possible. Schildknecht AG is a pioneer in the field of radio data links and has many years of experience with radio systems. The patented DATAEAGLE technology enables stable data transmission from PROFIBUS and also PROFIsafe.
Do I have to integrate the radio via the device description file?
No. The DATAEAGLE radio data transmission systems from Schildknecht do not have to be integrated into the control system via a device description file (e.g. GSDML for PROFINET or GSD for PROFIBUS). They act like a cable substitute and are transparent in communication. However, the devices can optionally be integrated into the PLC to activate the integrated diagnostics of the radio data systems. The diagnostic data provides information about radio interruptions or connection setups in the event of interruptions, allowing problems in the system such as defective cables or antennas to be detected.
Replacing cables with radio data transmission – without changes to the machine
Important for easy replacement of the solution for data transmission: If possible, nothing should have to be changed in the general setup of the machine or system. Often, the timing settings of PROFIBUS or PROFINET have proven themselves, fulfill important safety requirements, or require new approvals from TÜV and the like when they are adapted. This must be prevented. Wireless solutions often work with update times in the range of 16-32 milliseconds, while an update time of 1-2 milliseconds is common for PROFINET. Replacing it with such a solution would require intervention in the machine control system and thus possibly extensive testing and acceptance.
Wireless solutions from Schildknecht can be replaced 1:1 with existing cable or slip ring systems – without any changes to the machine. The replacement can be carried out quickly and easily by a company electrician, and extensive adjustments or re-certifications are not required.
With DATAEAGLE, no integration of data transmission into the hardware configuration is necessary. The device description files GSD (PROFIBUS) or GSDML (PROFINET) do not have to be changed and the “cable” configuration can be retained.

Is PROFIsafe via radio permitted?
The black channel principle allows the transmission of safe and non-safe process data over the same network or bus line. Independent 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 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, fibre optic cable, backplane bus or wireless. Neither the transmission rates nor the respective error detection play a role.
For PROFIsafe, the transmission channels are merely “black channels”. The DATAEAGLE 3732 and DATAEAGLE 4732 wireless PROFISAFE data radio systems were specially developed for the wireless transmission of PROFIsafe via Bluetooth. The use of the patented filter technology guarantees a stable, reliable radio connection, without bus errors in your PROFIsafe applications.
