Hello,

I just installed CODESYS V3.5 SP8 and updated the RPi Runtime (V3.5.8.0) on my Raspberry B+.

When I start a new project, I get the following Warning in "Application":
"Funktionsblock 'IoDrvGPIO' muss für den Zugriff instanziert werden"

Can someone tell me what to do?

Thanks!

Best regards,
Oleg

Hi Oleg,

this is a bug and will be solved for 3.5SP8Patch1 4BR

I have the same error, do you know when patch 2 will be released?

Hi,

18th February (which will include this fix)

Hallo,
versuche gerade mich in das Beispielsprogramm "I2CExamples" für den Raspberry einzuarbeiten und verwende CoDeSys V3.5 SP8. Ich bekomme die Meldungen

C0080: Funktionsblock 'IoDrvGPIO' muss für den Zugriff instanziert werden
C0080: Funktionsblock 'AdafruitPwm' muss für den Zugriff instanziert werden.

Was kann ich tun?

Hi,
this is only a precompile error, you could download the applicaton without any functional restriction.
This error will be removed to 3.5SP8Patch1 (next release)

Hello Edwin,
thank you very much for your answer. I have know zero errors and two more questions running the program I2CExamples:
1. The address of Adafruit 16-channel/12-Bit PWM is 16#40. Where can I put it in the example?
2. Since I can control 16 servos, where can I fix the output of a single servo?

Best regards

Hi,

a) screenshot
b) you mean you want to manually control each servo by value?
From this example here:

"c:\Users\<yourwindowsusername>\CODESYS Control for Raspberry PI\3.5.8.0\Examples\I2CExamples.project" </yourwindowsusername>

Adafruit_PWM.alrPWM[0] := lrMyValueforServo0
Adafruit_PWM.alrPWM[1] := lrMyValueforServo1
Adafruit_PWM.alrPWM[2] := lrMyValueforServo2
Adafruit_PWM.alrPWM[3] := lrMyValueforServo3
.
.
