Post by opineiro on How to manage variable types larger than 64 bits - Ethernet/IP ^{CODESYS Forge talk (Post)}
Hi there, I have a Keyence bar code reader connected to my plc through Ethernet/IP. The Bar code is 20 digits long (like 30100790020493036016), the scanner reads it correctly (I can verify that through the keyence software) but when it sends it through ETH/IP, it doesn't fit into a 64 bit variable and it trunks the data.(I've tried ULINT and LWord without success). When I loaded the EDS file, the read variable was defined as a byte with 128 bits length, which is quite strange for me. (see attached picture) How do I manage this variable? Thanks!

I have tried downgrading and it seems fine now. I am now on version 4.3.0.0 for the library. Mainly the PN controller caused the issue for me. Funny weird is that even the PN controller versions 4.3.1.0 and 4.3.0.0 cause the error. Version 4.2.0.0 works fine.

I have code written since version 3.5.16 to access the USB drive, how can I do that now the file access has been taken away? I have tried adding a sybolic link to the usb drive in the following directories: /var/opt/codesys/PlcLogic/ /var/opt/CODESYS/PlcLogic/ /opt/CODESYS/PlcLogic/ I still recieve a "FILE_OPERATION_DENIED" response when accessing the USB drive.

Hello, I don't really know what my problem was, but it's working for me at the moment. All i did was to change my code because of some REAL_TO_INT conversions, like i wrote above. And later a complete new Pi setup (because of 64x support with 4.10.0.0 now).

Hey schnepper, when i look into your c-file, i would say that only the main-function is declared with cext-addendum in your codesys-library-project. all yöur funtions in library has to be the cext-addendum when the external implementation is activ. if i remeber right, methods and other subelements dont need that, but every base-elements

Hello Jusito, Can you share your final code, please ? I tried to implement a similar feature (going online, doing the reset and the start). But I get a timeout on the reset/start when I'm testing the script. If you got something working, I would appreciate to see it.

Hi @eschwellinger Just wondering if there is any update when the Expression or part of it has no effect will be fixed? Also have the ability to open an FB when online and offline. It would also be great to be able to view the ST code block when online.

Hallo Ton, vielen Dank für den Tipp. Das Löschen der '.precompile cache’ Datei behebt das Problem. Beim nächsten Programmstart ist die Datei bei mir aber wieder da und leider der Fehler auch. Ich habe in codesys auch keine Einstellung zum automatischen Löschen der Datei beim Beenden des Programms gefunden. Ist bei dir der Fehler dauerhaft weg?

Hello to all! How can I read or write, via my main code (ST), to the registers present in the DO of my ethercat CoE servo drive? These objects appear in the list of the INITIALIZATION page, and from here I can only access them at startup. How do I access it in run time from my main PLC_PROGRAM?

I have created an EtherCAT slave code and fixed two slaves (IDs written in the 0xF050 object dictionary). The module IDs are 0x1 and 0x101, respectively. It can be scanned normally in TwinCAT, but when scanning in CODESYS, it reports an error. Why is this happening？text in the second pic means 'device cannot be found in repository'

Have you received any feedback or found any solutions to the load problem. We are running into similar issues, even without codesys running the load avarage is above 1 meaning that it is to busy already without plc code running. Hope you might have some more insight.
