Hi Roger

You can ask revpimodio2 related questions in the subforum of our makers corner: https://revolutionpi.de/forum/viewforum.php?f=41. Sven (the author of the library) frequently reads there and tries to answer the questions.

Re: Delay on DIO output when enabling AIO input

Hi Gianni, could you please share the image version of your RevPi and the version of the installed revpi nodes? Also the kernel logfile (/var/log/kern.log or dmesg) and revpi node logfile could be helpful in order to find the root cause of the delay. Do you use any other software on the RevPi which ...

Re: Modbus TCP as Master-Slave

Hi Joca, just to clarify if I understood your project requirements correct: You want to collect data from 4 modbus TCP slaves and export the collected data to your SCADA system via Modbus? The first part can be done by configuring an individual modbus TCP master for each slave (https://revolutionpi....

Re: PiControl porting to Lazarus/Delphi available?

Hi garysn, there is no Delphi library as far as I know, but you can probably access the process image directly via /dev/piControl. For some examples have a look into the article about using with C: https://revolutionpi.com/picontrol/?noredirect=en_US Using ioctl with lazarus: https://www.freepascal....
