Dear Nicolai, The command specified in your comment above doesn´t yield any result. There is no such file. Instead I´ve tried: # cat /etc/revpi/image-release: 2021-07-01-revpi-buster.img The system is fully updated. I could also not reliably reproduce the issue. But it happened to me multiple times ...

Hi Nicolai, Thanks for your quick reply. Since there can only be one Modbus Master at a time, would it be possible to use such a script in co-existence with the revPI Modbus Master running? E.g. the revPI Modbus Master service would poll the sensor registers at defined intervalls from Pictory and th...

I think I have confirmed that revPI keeps on sending the Output variable with the given action interval. Now my questions is, how do I send a ModBus command for calibration only once? The problem with the process image is that I don´t have direct control over the interface. So how can I send out jus...

Hi, I need to send a calibration value to different probes, e.g. PH and EC. Setting a register to 1 will activate the calibration function. However, I will only need to send this value once (when calibration should be initiated, not repeatedly). I am defining an Output_Word variable in Pictory, e.g....

Dear Nicolai, I just wanted to confirm that this issue exists. I am also using a Modbus 150 RTU Master and somehow my config.rsc had everywhere missing RegisterQuantities. The field was simply erased although a 1 was displayed in Pictory beforehand. After reloading the Startup config into Pictory, a...
