Hi, I have the same problem. However I am using ethernet connection not USB. I can ping the PLC and also connect to it via Wago ethernet settings, but I cannot upload using the Codesys 2.3. My PLC is Wago 750-862. The detailed error is - " connect: Connection refused Write attempt from invalid socket. " Any help would be appreciated.

Hi, I am new to modbusTCP and I am trying to access Input registers from codesys (3.5.SP13). The offset is 16#0000 and I am trying to access Channel 1[24] %IW24 to pull analog values. I am using pyModbusTCP and I need to supply a modbus address and the number of registers to read. What does 16#0000 mean in terms of the actual offset, how do I translate this number plus the channel to access this info via python? Any help would be appreciated, thank you.

Hello everyone, I created a visualization with a lot of REAL, with one or two digits after the decimal point. This causes me problems in terms of rounding and memory... is it possible to display an integer with a comma, like with PROFACE or SIEMENS? It's just an "abuse" of display, the comma is just on the visualization. This limits the memory (16 versus 64 bytes) and rounding is easier to manage... See print screen on proface software THANKS

CODESYS Forge

We are experiencing serious jitter issues on an ARM64 imx8. Until now, on rpi and beaglebone derivatives, and on Intel, we never encountered jitter issues unless they were already present on the device. In this case, as can be seen from the attached graph, we have excellent maximum latency. The cyclictest on the isolated core dedicated to IEC CODESYS tasks shows a latency of 37Β΅s, with an average of 14Β΅s. Usually, on all other devices, with an RT kernel, with the appropriate parameters to avoid frequency throttling, with properly managed IRQs, and with the disabling of large page sizes, the jitter measured by CODESYS is very close to the cyclictest latency. However, on this imx8, we are noticing a fluctuating value of +/- 300Β΅s that seems to be added to this latency, as if something occasionally miscalculates the sleep times by exactly +/- 300Β΅s. Two screenshoot attached. - Result of cyclictest - Jitter on CODESYS Tasks are assigned to isolated core!

If I do online monitoring of code in f.i. a function block, I cannot see if the function block is called or not. In software from other vendors you normally have an indication if the online code you are looking on is scanned at that moment or not. Is there a way in Codesys to determine in the online view if (parts) of the code are scanned or not? Thanks

Hi all, Is it possible to hide or show tabs from the PLC code? I have created a few tabs in my visualizations to configure the program behavior, I'd like to be able to hide some of them if the related option in the main tab has been disabled. Is that possible? if so, how should I do it? Thank you all in advance.

Pretty sure I know the answer, but thought I would ask just in case. Is there a way to set variables declared in a POU to private so that they can not be accessed from other POUs. I tried using the library pragma, but that just stops the variables being displayed in the selection tree. My compiler version is 2.3.9.62 if that's relevant, and I'm using an ABB AC500 V2 PLC. Cheers

Dear Forum, We are currently making the switch from OPC-DA (Codesys server) to OPC-UA (Running on a Codesys controller). We are using Codesys version 3.5 SP 20. Our Scada system is expecting Boolean's to be represented as a 0/1 (True Boolean) but the OPC-UA server is representing a boolean as False/True This indeed matches the OPC-UA standard, but is there a way to configure the OPC-UA server's boolean representation? Thank you in advance

What could the problem be, and how would I resolve this?

To search for an exact phrase, put it in quotes. Example: "getting started docs"
To exclude a word or phrase, put a dash in front of it. Example: docs -help
To search on specific fields, use these field names instead of a general text search. You can group with AND or OR.
