I'm also looking forward to KUNBUS addressing this issue soon. I'm currently working on a project with two MODBUS devices and am concerned about this issue.

I think that some of the issues I've been experiencing are related: https://revolution.kunbus.de/forum/viewtopic.php?f=6&t=2905 Could there be something about Modbus registers with 5 digits being mishandled somehow? It would be great to know what is causing this issue and if it's a piTest issue ...

Hello Nicolai Many thanks for suggesting that I look into the log files and those registers. That gave me new ways to debug what I'm experiencing. sudo journalctl -u pimodbus-master.service The log file indeed gave an error for reading the holding registers that I specified (40096/7 and others).

Answering my own question. Just need to follow the instructions for updating the Compute Module within the Connect: https://www.raspberrypi.org/documentation/hardware/computemodule/cm-emmc-flashing.md The Connect won't appear as a drive without first (setting up and) running 'rpiboot' (having booted...

I have a Connect+ and I'd like to use it as a MODBUS TCP master to read a holding register from a MODBUS device. The holding register is, in this case, 40097. The MODBUS device is connected to my network and from a PC on this network I can read the register -- using a Python script -- and it always ...

Is the checksum (MD5/SHA256, etc.) available for the RevPi Buster download?

I was wondering about this as well. I can run shutdown from the OS, but then the only option to power-down (or power-cycle) the Connect+ is to unplug it from power (and plug it back again). Is this the only way? Is it the recommended way? Would adding a switch module to my DIN be the way to go? Than...

Hello! I've just received a Connect+ and would like to upgrade to the latest OS from a Linux machine. I'm looking for something like this: https://revolution.kunbus.com/tutorials/images/install-jessie/ but more recent and for Linux rather than Windows. Any pointers to the best/easiest way to do this...
