v2024.0.7.170010
2025-08-07
Fix for bug which could occasionally prevent the board to reach the
operational state after booting the robot controller. Remedy was to restart the
robot controller another time.
Adds support for EtherCAT slave (SubDevice). This requires at least robot system
software YAS5.70.00A for YRC1000 or YBS4.24.00A for YRC1000micro.
v2024.0.4.123413
2025-04-16
Initial release.
Configurations
The board supports the following EtherCAT configurations:
Slave (SubDevice)
Note
The slave can be configured as one of the following data packet sizes:
2b, 4b, 8b, 16b, 32b, 64b, 128b, 256b, 436b, 440b and 512b*.
* Depending on the type of robot controller and the installed option boards,
some of the larger data packet sizes might be available in the robot setup.
Important
Master (MainDevice) or safety slave (FSoE) are currently not supported.
Mount the board
It is a PCIe (PCI express) board, and can be can be mounted in either the
left or right PCIe slot of the robot controller.
Connect the EtherCAT cable(s)
Important
The YRCP-MP4P board is having a 2x2 ports configuration.
This means that there are two physically separated networks
(each with 2-port switch).
The functionality for the two networks is defined as follows:
Port X1, X2 (upper ports): EtherCAT SubDevice. These are used for the network where the robot controller is a slave
(and connected to a master such as a PLC).
Port X3, X4 (lower ports): not used.
Board firmware
Note
It is advised to use the latest board firmware
(see version information at the
top
of this document).
Check version
Start the robot controller (maintenance mode).
Access the webserver of the board (web based management, WBM) by entering one
of the given IP addresses in a webbrowser.
As it is not using encryption (using HTTP instead of HTTPS), it might get
blocked with a message like this:Browser security warning.
Proceed by clicking Continue to xxx.xxx.xxx.xxx (unsafe)
Login using the default credentials (user: admin / password: 00000000).
The actual firmware version is shown (in short notation) in the main screen’s
top right corner:Version info shown on the main screen.The more detailed notation of the firmware version is shown in
Menu Overview » General Data:Detailed version info.
Update process
Follow above steps for checking the firmware version.
Open the firmware page using menu Administration » Firmware update
Click Browse to select the new firmware file (.raucb) on your PC.
It will then show up:Firmware selection.
After clicking Start Update, the file will be uploaded to the board.Firmware transfer (upload) progress indicator.
After finishing the transfer, the board will install the new firmware.
During this process, the webserver is not accessible:Webserver connection lost.
The installation should take no more than five minutes.
If everything went well, the webpage will automatically reloaded and display
the login screen. Login and verify if the new firmware version is shown.
