Hallo zusammen, ich habe schon einige Zeit 16 DS18B20 am 1 Wire laufen ... auch die ganze Zeit stabil ... jetzt habe ich ein PWM Signal über i2c für eine Pumpenansteuerung zusätzlich in Betrieb genommen.. nur das Signal für die Pumpe geht über i2C ... 100Hz 10ms. Es läuft auch alles soweit ... nur fallen mir jetzt die Temperaturen in Abständen aus ... Vertragen sich die beiden Systeme zeitlich evtl. nicht so gut ... 1 wire extra task mit 200ms Prio 0 i2c task 10ms ... damit die 100Hz auch übertragen werden Prio 1 (Adafruit_PWM) Main Task 20ms Prio 5 Oder jetzt besser beides über i2c abrufen ... ist aber dann evtl. für die DS18B20 zu schnell ? Oder sind die 5V vom Pi jetzt zu schwach für beide Signale? Vielen Dank euch

Switching to Linux can be a great choice, but I understand the concern with Codesys development. Using a virtual machine (VM) is definitely a solid option, as it allows you to run Windows and Codesys without compromising your Linux environment. Many users have had success with this setup, and it keeps everything neatly contained. Alternatively, Wine can work for some applications, but compatibility can vary. If you choose the VM route, be sure to allocate enough resources for smooth performance. Good luck with your transition! stickman hook 3

It sounds like an exciting project with the Revolution Pi and USB joystick! Just like in the dummies world cup game, where teamwork and coordination are key, integrating your joystick with CODESYS will require a solid approach to ensure smooth control of your robot. Have you considered using a library that bridges joystick input with CODESYS functions? Good luck!

Hi, I have similar issue. Is that possible to use more than 4096 registers with Modbus RTU slave?

I'm not sure it will work, but you could try it with the CmpCharDevice library. You could create a function block that looks something like this: As input for the filename, you have to use your Linux device, e.g.: '/dev/input/event0' '/dev/input/by-path/platform-button@23-event' Off course you must also pass the pointer to the memory where the data can be written to and the size (count in number of bytes) of the buffer. FUNCTION_BLOCK FB_CharDevice VAR_INPUT szFilename: STRING; pbyBuffer : POINTER TO BYTE; udCount : UDINT; END_VAR VAR_OUTPUT iState : INT := 0; nrBytesRead : DINT; END_VAR VAR xInit : BOOL := TRUE; dFlags: DINT := CmpCharDevice.ACCESS_MODE.O_RDONLY + DINT#4000; // see details for flags: http://linux.die.net/man/2/open, + DINT#4000 is for non-blocking hDevice: CmpCharDevice.CmpCharDevice_Implementation.RTS_IEC_HANDLE := -1; Result : CmpCharDevice.CmpCharDevice_Implementation.RTS_IEC_RESULT; END_VAR IF xInit THEN hDevice := CmpCharDevice.CDOpen(szFilename, dFlags ,Result); // if it would not succeed, the result is -1 (Invalid handle) IF hDevice <> 16#FFFFFFFF AND Result = 0 THEN iState := 5; END_IF xInit := FALSE; END_IF IF iState = 5 THEN nrBytesRead := CmpCharDevice.CDRead(hDevice, pbyBuffer, udCount, Result); ELSE nrBytesRead := 0; END_IF Make sure you close the connection properly, maybe by overwriting the default FB_Exit method of the FB: // Clean up device IF hDevice <> 16#FFFFFFFF THEN __TRY CmpCharDevice.CDClose(hDevice,Result); __CATCH ; __ENDTRY iState := 0; END_IF
