Der Eintrag in /etc/CODESYSControl.Usr.cfg war schon vorhanden. Bisher habe ich das Gerät Pi MC SL verwendet. Laut H. Zenker ist das die "Produktionsversion“ der Raspberry-Laufzeitumgebung. Gibt es kein MC SL Runtime Package mehr? Ist dieses in der Standardinstallation nicht mehr vorhanden und muss manuell installiert werden? Beim Wechsel auf Pi 64 kann ich nicht mehr kompilieren wegen folgender Fehlermeldung: "cmperrors interfaces, 3.5.5.0 (system): C0338: Die Bibliothek 'cmperrors interfaces, 3.5.5.0 (system)' wird nur in 32-Bit-Applikationen unterstützt" Vielen Dank für die Hilfe

This is a consequence of how computers store floating point numbers. 0.1 cannot be exactly represented in a computer. This is not a CoDeSys thing. Here is a link to a converter to show you the exact value that is represented when you use a REAL data type (which is a 32 bit float). https://baseconvert.com/ieee-754-floating-point If you really need to keep track of 0.1 increments. use INT OR DINT and then add 1 each time and assume that there is one decimal place.

Yes it had been the case I believe as I have seen that message regarding they were not the same. I had update the device though to match them and that still did not fix the problem. I gotta say I wanted to get out of that situation and attempted a lot of things and then I did two things at the same time that fixed my problem: Wiped the 64 bit version and installed the 32 bit version Installed latest SP20 I wish I knew which one of these actions fixed the problem but now I gotta catch up on this IDE learning; it's been quite a learning experience I have to say! Thank you very much for your time and advice; much appreciated!

Post by salvadegianluca on SysPlcCtrl23 and C0338: The library 'cmperrors interfaces, 3.5.5.0 (system)' is supported just in 32 bit applications ^{CODESYS Forge talk (Post)}
Good afternoon to everyone; I'm stuck with this error and I don't know how to get out from it... I tried several time googling for alternative systems to control the PLC applications and resets but without success. I would like to realize the possibility to reset the CPU and to start/stop the applications as it was possible with the SysPlcCtrl23, but this library is no longer supported in 64 bit systems and it seems due to the cmperrors interfaces sub library that was included in the above said one. Someone found a work around for this issue?

Post by solidlogicguy on Little endian to Float from Modbus RTU ^{CODESYS Forge talk (Post)}
Hello, I got a device from which I require to read values from I am using a WAGO PLC 750-8212 and I am communicating through Modbus Master FUNCTION BLOCK from library WagoAppPLCModbus in Codesys 3.5 to this device. I already receive data from the device that is a CVM to monitor voltage from a fuel cell. The technical support of the company that makes these devices says that the data is sent in little endian form. And I want to convert it to a float value. The tech support sent me the next instructions of how to do it but I am new using codesys, so any advice or help I will really appreciate so much. Message from tech support: The process is complicated, better to do it with already implemented library in the language/program you use. Basically the process should be next: To convert the two Modbus registers containing parts of a 32-bit float in little-endian byte order to a floating-point number using mathematical operations, you first need to combine the two 16-bit integers (assuming reg1 is the lower word and reg2 is the higher word) and then interpret the result according to the IEEE 754 standard. Given: - Register 192 (reg1) = 4096 - Register 193 (reg2) = 14884 Step 1: Combine the two registers. Since we are dealing with little-endian byte order, reg2 is the high word, and reg1 is the low word: combined = reg2 * 2^16 + reg1 combined = 14884 * 65536 + 4096 combined = 975175680 + 4096 combined = 975179776 Step 2: Convert the combined value to binary: combined_binary = '1110101101011100000000000000000' Step 3: Split the binary into IEEE 754 components: Sign bit (1 bit): 0 Exponent (8 bits): 11101011 Mantissa (23 bits): 01011100000000000000000 Step 4: Convert the binary exponent to decimal and subtract the bias (127 for 32-bit floats): exponent = int('11101011', 2) - 127 exponent = 235 - 127 exponent = 108 Step 5: Calculate the mantissa as a fraction: The mantissa in IEEE 754 format is the fractional part after the leading 1 (which is implicit). Therefore, we need to convert the binary mantissa to decimal and add the implicit leading 1: mantissa_fractional = 1 + int('01011100000000000000000', 2) / 2^23 mantissa_fractional = 1 + 18688 / 8388608 mantissa_fractional = 1 + 0.002227783203125 mantissa_fractional ≈ 1.002227783203125 Step 6: Combine the sign, exponent, and mantissa to get the float value: float_value = (-1)^0 * mantissa_fractional * 2^exponent float_value = 1 * 1.002227783203125 * 2^108 Because the exponent is quite large, the resulting float value is a very large number.

Post by matt-s on HMI Pushbutton/Move Instruction ^{CODESYS Forge talk (Post)}
I am having an issue where the manual start/stop push buttons on the HMI are supposed to take the pumps/blowers out of auto. The logic I have attached works for the pumps, but not the blower. From what I can tell it is the exact same logic, but it is not writing a 0 to the Auto PB variable. Attached is the logic, cross reference list to show nothing else is writing to it, and the HMI screen. Any help? Am I missing something? I am using a Groov Epic PR1, my software version is 3.5 SP19 Patch 5 32 Bit.

Post by karol-abktech on Raspberry and problem with runtime ^{CODESYS Forge talk (Post)}
Hi, My problem is with raspberry pi 4 with 2 GB ram,. Install codesys is correct but runtime works only few seconds or I can connect with device few seconds. I can ping raspberry and in system info I can see " !!!! Warning: no runtime license - running in demo mode(~2 hours)" but it is 2 minutes after runtime. When I press Start runtime I have another few seconds when I can connect to raspberry. After this time I couldn't find device. Of course, reapet start runtime works every time on few second. Raspberry is new and works with fresh install raspberry os 32 bit. Where should I start looking for solve of my problem ?

Post by eschwellinger on Zielsystem stimmt nicht mit dem verbundenen Gerät überein ^{CODESYS Forge talk (Post)}
na ja es gibt halt einfach die Möglichkeiten: 1. Man installiert Raspberry PI OS 32Bit -> dann geht PI SL und PI MC Multicore als Target 2. Man installiert Raspberry PI OS 64Bit dann muss es PI64Bit sein falls der Übersetzungsfehler nicht in einer Bibliothek ist (die du vielleicht nicht ändern kannst) https://faq.codesys.com/pages/viewpage.action?pageId=128253958 Hier der Hinweis was man tun muss das dein IEC Code für 32Bit als auch 64Bit Targets funktioniert Also entweder zurück auf Raspberry PI OS 32 Bit: nur zur Info noch was im Config file steht für welche Plattform/Produkt [CmpRasPi] Architecture=aarch64 (-> 64Bit PI) oder Architecture=armv7l (-> PI MC Multicore) oder Architecture=armv6l (-> PI SL Single Core)

Zu der o.g.

Beim Doppelklick auf die Fehlermeldung würde ich einen entsprechenden Hinweis erwarten. Aber es passiert gar nichts. Wenn ich im Bibliotheksverwalter manuell den Baum durchsuche, finde ich nur Referenzen auf CmpErrors2Interfaces, die ja 64bit kompatibel sind. Leider konnte ich bisher nur eine SSD mit einem 64bit OS für den RPi zum Laufen bringen. Deswegen gehen mir langsam die Ideen aus. Vielen Dank für die Hilfe

Post by dhumphries on Rounding error in simple addition ^{CODESYS Forge talk (Post)}
Thanks for the response, as I've thought about this problem over the last month I began to suspect this was a problem with not being able to exactly represent .1 as a 32 bit binary number. I think I've found a work around by making the number an integer, then dividing it by 10 and storing that value as a floating point number. There is still an issue with the value not being exact somewhere in the 8th or 9th decimal place, but because I'm incrementing an integer value then dividing it, the error doesn't compound.

Hello, I have just went through all steps shown on Codesys YT channel https://www.youtube.com/watch?v=RPoPscbo3Kc And it works, I have installed PI OS 32 bit and choose Single Core. However, immediattely when I create standard project with Raspberrz pi device, "Application" is underlined, like there is an error, but in reality there are no errors, and I cannot see what are these 3 messages like shown in attachment. Aside for this red underline, everything seems to work fine. How to correct this? Thank you! Update: I have found what errors are, but not sure how to correct them: Identifier 'IoDrvGPIO' not defined Function block 'IoDrvGPIO' must be instantiated to be accessed 'IoDrvGPIO' is no component of 'IoDrvGPIO'
