Yes, use SSH keys and execute the commands on the remote device over the network.
https://revolutionpi.com/forum/viewtopic.php?t=4224There is the Bit Mirror Python example, take a look here: https://revolutionpi.de/forum/viewtopic.php?f=6&hilit=bitmirror&p=9196&t=2535&sid=243930e8379560d9d658ecce7b9f1a65#p9196
You may need to save your PiCtory change and perform a driver reset, then you should be able to access the variable “LM” like so:
piTest -w LM,1 |
Or via Python and the popular Revolution PiModIO2 library. See the “BitMirror” forum for examples:
https://revolution.kunbus.de/forum/viewtopic.php?f=6&t=2535&p=9196&hilit=bitmirror#p9196
Yes, but this application is beyond the reach of KUNBUS.

The gateway module for CANopen has been discontinued
Yes, this is possible, take a look here
EtherCAT Master with RevPi Codesys and Slave RevPi EtherCAT Gateway
Yes, thanks to a soft PLC this is possible, e.g., with CODESYS:
Only low-level debugging can help. Please create, e.g., with an oscilloscope or a logic analyzer traces for the analysis of the signals on the RS485 interface. Are there cyclic or sporadic disturbances, etc.? What does the image on the RS485 interface actually look like?
https://revolutionpi.de/forum/viewtopic.php?f=14&t=2697#p9813
Yes, it works with various USB-RS485 interfaces. These are then addressable via “/dev/ttyRS485” and “/dev/ttyUSB2” for example.
If it is about Holing Register, the behavior is correct.
No, unfortunately this functionality does not exist at the moment.
Yes, this is possible. e.g., with CODESYS

Serial number. You can find this information here:
We’ll restore your CODESYS license.
Yes, we recommend these minimum clearances to ensure sufficient air flow around the enclosure when the Revolution Pi modules are mounted on a top-hat rail.
Excessive temperatures can damage your module.
Make sure that the ambient temperature in the control cabinet is less than 55 °C.

Without conveying a preference, I can say that we offered monitors from Faytech in our online store.
However, we have benevolently removed them again, as well as other additional items to focus on the core business.
Yes, it may be feasible. There is a discussion here:
Take a look here: Video Webcam Stream - Revolution Pi Forum
Unfortunately, there is no implementation which interest as possible, Our source code is public. The interfaces are documented and freely available in our GitHub repository:

Use "pi/raspberry". Please note that if you want to log in with a keyboard and HDMI screen, the default layout is English (QWERTY).
How do you log in to the system? Possibly via HDMI screen and USB keyboard? Then it may be due to the English keyboard layout of the target system. So QWERTZ or QWERTY.
It should be printed on the side of the device.
Yes, the Modular Gateway modules do not have master/controller functionality. They function as slaves.
Yes, you can run a PROFINET Master not with the Modular Gateways but, e.g., with CODESYS:
Please try to set the hostname with:
sudo raspi-config |
RevPi Core / Core 3(+) / Core S (until Revision 1.0) / RevPi Compact / RevPi Connect (+) / RevPi Connect S / RevPi Connect SE:
The mac address is set during factory reset and can be changed afterwards by modifying the file /boot/config.txt. The dtparams eth0_mac_* (and eth1_mac_* on Connect and compact) are read from the kernel driver.
RevPi Core S (starting with Revision 1.1) / RevPi Core SE / RevPi Connect 4:
The mac address is written into an eeprom, which is attached to the ethernet controller. The mac address can be changed (written into the eeprom) with the tool /usr/sbin/revpi-set-mac (part of package revpi-tools).
NOTE: The mac address for wlan0 and eth0 on Connect 4 are set differently, as the controllers are directly attached to the compute module. These mac addresses are set via an udev rule. See section revpi_connect4 in file /lib/udev/rules.d/50-revpi.rules
Please refer to this article Revolution Pi Connectivity .
The dhcpcd is no longer used since the Bullseye release and the NetworkManager is used instead. You can find more details on the changeover in the release notes of the first Bullseye image. The IP must therefore be configured in the NetworkManager. If you activate the dhcpcd, it gets in the way of the NetworkManager.What knowledge can we derive from it?
Take a look at this discussion
Watch this video tutorial #6 explains how a network configuration works with two networks:
https://revolutionpi.com/tutorials/video-tutorials/?noredirect=en_US#VT6
Yes, it is possible. You can combine the two ports into one bridge. The necessary steps can be found here:
https://github.com/RevolutionPi/revpi-ansible-recipes/blob/master/roles/network-bridge/README.md
No, the Revolution Pi is by default configured using DHCP
If you want to set up a static IP address, take a look at Video Tutorial 07 – Static IP Address
The RevPi Connect 4 uses mDNS, which makes it easier to locate the device in the network
You can see an Example, how to convert data from a pressure sensor. The sensor has a range from 1V to 5V and a measuring range from 0kPa to 2kPa.
See here: Sensordaten umrechnen - Revolution Pi Forum
If the Raspberry Pi can do it, so can the Revolution Pi.
KUNBUS doesn't have any shares in it, but the possibility is certainly there to run entirely different OPC servers or clients on Revolution Pi devices
No, but it would work with the Revolution Pi Compact, where we allow 250 usec cycles for the digital I/Os and analogue outputs.
The Revolution Pi DI/DO/DIO modules cannot be used for such applications due to the limitation of the PiBridge communication cycle.
No, the sampling in microvolt is not possible but with the Revolution Pi Compact, there is a workaround to increase the sampling frequency.
https://revolutionpi.com/tutorials/analoge-ein-und-ausgaenge-compact/?noredirect=en_US
We cannot recommend down clocking the CPU. This means that the functionality of PiControl can no longer be guaranteed correctly.
Yes, it is true. Here is the datasheet:
https://datasheets.raspberrypi.com/cm/cm3-plus-datasheet.pdf
Yes, this is technically possible, but without official support. The two network interfaces “pileft” and “piright” are available in the system. Via these two interfaces, a network can be configured between two communication partners that are connected via the PiBridge.
Revolution Pi Core #1 | Right PiBridge | Left PiBridge | Revolution Pi Core #2 | |
Network Interface | piright | pileft |
Take a look at Tutorial 07 – Static IP Address: https://revolutionpi.com/tutorials/video-tutorials/?noredirect=en_US#VT7
No, the Revolution Pi doesn't retain the last value when power is off (except for the real-time clock, which is buffered for 24 hours).
Take a look at the PiBridge driver source, it's pretty well commented.
Yes, take a look here
There is a fruitful discussion about the documentation of the RSC files and types in it
The process “pl011_pio_tx” is a sub process that is responsible for the data exchange between the modules and Revolution Pi. This requires about 20% of the CPU resources.
There is nothing you can configure about this behavior.
The standard value of the baud rate is 19200. No threshold is defined for the RS485. You must proceed randomly to define the maximum baud rate threshold that suits you.

TeamViewer-Revolution Pi has moved to a new product called TeamViewer-IOT. Take a look at Video Tutorial 24.1 – TeamViewer IoT for a brief introduction.
https://revolution.kunbus.com/tutorials/video-tutorials/?noredirect=en_USWe do not support natively a g-code sender on our platform. But there are several user tutorials “How to implement g-code sender on the Raspberry Pi”.
https://cebess.wordpress.com/2019/10/14/installing-universal-g-code-sender-on-the-raspberry-pi/
Partly because KUNBUS does not guarantee or support the functionality. However, there are first successes, see here:https://revolutionpi.de/forum/viewtopic.php?f=6&t=1348&sid=8f14e354417f231440acea6579478bdc#p9212
Please take a look here, maybe you get your answers for installing ROS
https://revolution.kunbus.de/forum/search.php?keywords=ros&sid=642735a3d64404db2e3586ae95bdd512
Our image is derived from Raspbian, perhaps you get further instructions here http://wiki.ros.org/Installation
Or here https://www.ros.org/support/.
Yes, this is possible with a few steps. Take a look here:
The resistance between the pins is 100kOhm. The resistance between the RTD pins of the two Revolution Pis is also 100 kOhm. The PT100 has a maximum of 3kOhm. You can calculate the influence of 100kOhm on 3kOhm with an error calculation.
Usually, time is synchronized automatically. You can check the status via

The Bullseye image uses UTC as the system timezone. For previous images, you can manually change it by running:
sudo timedatectl set-timezone UTC |
Yes, there are “udev rules”.
https://revolutionpi.de/forum/viewtopic.php?f=3&t=2646#p9647
/dev/serial/by-id path and only /dev/serial/by-path/ is generated. What can I do so that both devices are displayed?Please update your device so that the UDEV rules are up-to-date.
Please check the watchdog jumper at connector X4.

We just uploaded a fixed version of RevPi-tools (2.0.1-1). After an update via “sudo apt update && sudo apt upgrade” everything should work as expected.
https://revolutionpi.de/forum/viewtopic.php?t=3732#p13466
Please check if the Wi-Fi network is compatible (WPA3 is not compatible).
No, unfortunately, there is no native SMS functionality. You can use a web-based SMS service which is called from your software on the Revolution Pi module (requires internet access). Another way is to attach a hardware modem that offers that functionality.
https://revolutionpi.de/forum/viewtopic.php?f=6&t=3148#p11207
Yes, Wi-Fi is integrated in the Revolution Pi Flat
In general, Wi-Fi works with additional hardware. We recommend the LTE & Wi-Fi router for professional use:
Yes, just take a look at these pages
