Post by talhaali on Persistent variables not working for Control Win ^{CODESYS Forge talk (Post)}
Hi everyone, I am facing issues with persistent retain variables. It was working fine. I added a few new Persistent variables and it stopped working. If I do cold reset it holds persistent variable values. But when I close control win gracefully, and opens it again then it does not. Even, it is not saving ret file in application.

Post by eschwellinger on Gateway ^{CODESYS Forge talk (Post)}
yes, sorry this is an accident in current Gateway Version. Either use 3.5.20.0 Version. (download from CODESYS Store standalone setup - https://store.codesys.com/en/codesys-edge-gateway-for-windows.html ) or do it manually by: 1. stop Gateway: 2. Add in c:\Windows\System32\config\systemprofile\AppData\Roaming\CODESYS\CODESYSGatewayV3\xxxxxxxx\Gateway.cfg [CmpEdgeGateway] MaintenanceMode=1 3. start Gateway again 4. add it to your CAS Instance

Hi, thanks for the fast response :) Yes I Have a .err file. Sorry I forgot to upload it. It is a binary file though... "Runtime goes in exception before the shutdown ?" I think it goes into exception at the same time as the power is lost...

Post by gabor-n on PNIO Connect Parameter Error ^{CODESYS Forge talk (Post)}
It's a bit confusing, the two RPI is the same (board, OS, runtime, programing with Codesys V3.5 SP20 P2) but the one has a codesyscontrol.cfg file and the other has a codesyscontrol_user.cfg file. Shouldn't be the same? And because I over Codesys 3.5 SP 12 this would be the '_user.cfg' for both. Attached...

Post by davidmic on What is this ST syntax? ^{CODESYS Forge talk (Post)}
I found some structured text code which contained this statement: bHidden:= TRUE(*NOT _somevariable*) I haven't seen TRUE() used like a function before, and I also haven't seen the enclosing asterisks * * before. What do they do? (sorry if this is a duplicate question, I don't know what words to use to search for this syntax)

Hi, Is it possible to know of an output of a function block is used? I've found there is a way to find unused inputs of a fb, through the attribute: is_connected. But I'm wondering if the same can be done for an output. Thanks in advance!

Hi if you add in (ttyAMA0 should fit to your HAT's device [SysCom] Linux.Devicefile.1=/dev/ttyAMA0 to /etc/CODESYSControl_Usr.cfg since 4.12.0.0 version /etc/codesyscontrol/CODESYSControl_Usr.cfg then access in CODESYS with Com1 should do it. Keep in mind that only adapters work (for RS485) which do determine the send/receive direction in hardware

yes i took the library from another forum: https://forge.codesys.com/forge/talk/Runtime/thread/f1400b71b6/, it is made for the ads1115 but the ads1015 is almost the same device with same adresses i only changed the divide value of the analog value, because thats the only difference between the ads1115 and ads1015.

Is it possible under CODESYS V3.5 SP18, to connect a split (german Leitungsverzweigung) with an existing block (e.g. AND-module)? Or to connect the output of an existing block to the input of an existing block (e.g. OR-block)? Any ideas? P.S.: Sorry for the german title, I do not know how modify the title.

Post by andrax on CodeSys Raspberry pi I2C driver not found ^{CODESYS Forge talk (Post)}
Ok, this is a test programme with ADS1115. It is currently configured for the TCA9548 muxboard. If you want to run the ADS1115 single, then change the settings to the default values: ‘Is Multiplex:’ False ‘Stage mux channel numbers:’ [0,0,0,0,0,0,0,0,0] It is also important that the libraries are installed correctly here. But should be in this project

Okay i will try. I tried already the different settings. The CodeSys version i use, is CodeSys 3.5 SP20 Patch 3. The device which i use is CodeSys Control For Raspberry PI 64 SL version 4.13.0.0. The wiring should be okay because i'm using the Edatec ED-CM4IND-1432-4C(EU).

Post by lsislsis on SIGABRT Error ^{CODESYS Forge talk (Post)}
After many tests i see that problem comes when serial communication established for modbus rtu. If the slave device not connected we don't see the exception. If the slave device connected at serial port then we have exception about 1 hour after startup and every 10 or 15 minutes. Any suggestion?

Post by tyronnosaurus on SysLibMem.lib Where To Download? ^{CODESYS Forge talk (Post)}
It should come by default on a normal install of Codesys 2.3, but it's a bit hidden: Like for any other library, go to Resources > library Manager > Right click on list of libraries > Additional library. On the browser that opens, instead of looking in the default folder, use the dropdown menu at the bottom to change the folder (SysLibMem should be on the 3rd folder).

Hi, I updated codesys IDE to the newest version, but I lost the "professional developer edition" in the process. It still works fine on the older version I have been using previously. Do you know what the easiest process for getting the same integration in the newer version? It is only the GIT integration that I really miss.

The story behind: I have had a EhterCAT fieldbus system where sometimes error frames occured. I noticed that the master is tolerant for some error frames, but if there are very much error frames the bus goes in error state. Does somebody know the limit of error frames above the bus changes to error state?

Post by durallymax on Help understanding analog in-/outputs ^{CODESYS Forge talk (Post)}
WAGO will use 0-32767 as the raw units. Note a value of 3 means over/under range. Map that IO however you please, then scale in your program using any of the available libraries or with your own simple y=mx+b scaling formula to get to the engineering units you desire. Inverse for the AO to get back to 0-32767.

I just had the same problem in 3.5 SP19 Patch 6. Trying to use a textlist for Combobox Integer element. The textlist cannot be selected in the IDE, and is not found when manually entering the name. The textlist is copied to the device, but is not used. Can confirm, that copying an existing textlist and renaming it does work.
