In structure i want to add a tag with systemnumber and sensorname. '320.001-RT401' In pou i use this RT401: NTC10k;, and tried this RT401: NTC10k(Tag:='RT401'); Anyone done this?

Post by nmcc on Viewing PDF in WebBrowser Visual Element ^{CODESYS Forge talk (Post)}
I am trying to show a PDF in a WebBrowser element. I have the file saved to the drive of the HMI/PLC. I am linking it in the URL parameter of the WebBrowser using the following directory link. 'http://localhost:8080/$$sdcard$$/FileName.pdf'. This allows for the program to download without any errors. When I navigate to that screen it is just a white box and nothing shows. I attempted putting the same link in the show parameter and I get a loading icon on my cursor when monitoring the HMI with my PC. Any help is appreciated. Thank you.

Post by jens on Modbus tcp - channel ^{CODESYS Forge talk (Post)}
Help wanted This is the first time i'm doing a Modbus Tcp project. I have some VLT with a extension module MCA-122. i'm currently unable to write to the VLT slave, but i can read from status word parameter=1603 and address := 16029 where the address is calculated from parameter is ((id x 10)-1). in the manual the functions that are supported are 3 hex, 6 hex, 10 hex, b hex and 11 hex. read holdin registers, write single register, write multiple registers, get comm. event counter, report slave id. i'm only using the Modbus Slave Channel is this wrong when trying to write to the vlt ?

Post by i-campbell on Official MQTT-Client: MAX_RECEIVE_BUFFER_SIZE_EXCEEDED ^{CODESYS Forge talk (Post)}
I can't answer why it's not resetting, but from the description of g_udiMaxReceiveBufferSize, I would guess the sum of sizes of the mqtt packets received in one cycle exceeded this value. So the answer may be to increase that parameter. https://content.helpme-codesys.com/en/libs/MQTT%20Client%20SL/Current/MQTT-Client/Common/Params/MQTTParam.html https://content.helpme-codesys.com/en/CODESYS%20Development%20System/_cds_dlg_library_parameter.html

Post by ewi04 on Recipe Manager - RecipeManCommands, load & write wrong values, Bug? ^{CODESYS Forge talk (Post)}
The individual structures were declared in a separate global variable list on a trial basis. But even this did not change the behavior. A total of 1667 variables are processed in a recipe. A reduction (e.g. saving only the first three drive parameter sets) also brought no change.

Post by scarter on Bit / Bool data types in function parameters ^{CODESYS Forge talk (Post)}
Any reason BIT and BOOL data types are not interchangeable? Trying to make a function which takes a BOOL IN/OUT parameter (Not allowed to use BIT) In the main logic if I make a DINT variable, and want to use each bit on different functions CODESYS will not allow it.

Post by koppit on SysComRead Timeout Parameter ^{CODESYS Forge talk (Post)}
Im using SysCom ver. 3.5.17.0 and seem to have the same issue on a Raspberry Pi. It's not waiting for the requested number of bytes, no matter if "ulTimeout := SYS_INFINITE" or any other value. The only solution I have found is to stall the program to allow the serial port to recieve the data.

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...

Hello everyone, I am using SP19 patch 2 on a Kunbus device with runtime package 4.9.0.0. I am having the same problem as mentioned above. With the FB File.open I get the FILE_OPERATION_DENIED error. I have also tried the path /var/opt/codesys/PlcLogic. Any advice? Chris

When I load the SMC_GroupWait command twice in a row into the buffer an error occurs when I try to MC_MoveLinearRelative in the dynamic coordinate system. If I use MC_MoveLinearAbsolute in the dynamic coordinate system, it still works

Good morning, Yes, this is a known bug that has been reported. For now, the only workaround is to open the function block instances from the device tree. Regards, -Shawn

Die im FB 'zeitschalter' deklarierten Variablen sind nur lokal gültig und global nicht sichtbar. Deshalb kannst du in'PLC_PROG' nicht darauf zugreifen. Hier must du entweder eigene Variablen deklarieren oder globale Variablen in einer globalen Variablenliste (GVL) anlegen. mfg Reinhard

Thanks for the update, Since you can't double click is there another way to enter the FB when online and see the running code of that instance? When can we expect to see v1.0?

Post by fless on See only variable ^{CODESYS Forge talk (Post)}
either you have "Insert with namespace" enabled in the SmartCoding options or your GVL_GLOBAL starts with {attribute 'qualified_only'} btw it's considered good practice to put the namespace in front of the variable. you could have variable with the same name in your PRG or FB.

Hi, I have the same issue. It should be possible to create a certificate without using Codesys IDE. The functionality of the security agent could be handled in some fb. Can anyone here give the right hint?

Hello, you probably fixed in this meanwile, but I think your problem comes from dependencies of other libraries. I see in the Project column of errors the "caa types extern" and "caa fb factory", that both have dependencies. Try to check there. Regards, Francesco

Post by salvadegianluca on How to use TON inside an FB that is instanced within a Visu page ^{CODESYS Forge talk (Post)}
Hi everyone; I'm building a project in which the drag of the mouse over some controls (or the click event) changes the background color of the control items; this change of color is made with an FB that assignes a color code to the background with MUX command based on the value of an enumerator, this part is perfectly working but, when I'm using a touchpanel instead of a web visu (controlled by a mouse) I get into some issues as it seems that the touch operations are not triggering the MouseEnter and MouseLeave properties as it's done with the mouse.... For this reason I'm trying to add a TON to my FB and, if the enum that changes color remains at the same state for more then 3s I'm automatically resetting it to it's "0" so the item gets back the not selected color. Anyhow it looks like the TON function from library is not working in these FB that are instanced in the various visualizations, as instead they do if I create some instances within the POUS. Anyone has ideas of how to make them work?
