Post by ac-spr on Runtime variable that indicates a user is online to the code ^{CODESYS Forge talk (Post)}
Looking to access a variable at runtime that indicates a user is online to the code. essentially want to use this value to feedback to the user on the HMI. we use turck and bosch rexroth devices if this information helps. I was hoping there was a variable at the application level, or a library that could be used but I was unable to find anything. I know there's a pop up when you try to login/ go online to the code when a user is already logged in, so the system does provide an indication that it knows already online, but has no access to a value from what I can see. Any help is appreciated

Post by alez on CANopen safety , SRDO error behavior ^{CODESYS Forge talk (Post)}
I have a project in which there is a Safety device in CANopen, and the PLC interfaces with it as Master. I would like to understand if it is possible to set the behavior in case one of the SRDOs that I receive from the slave is no longer received. From what I have seen, if the SRDOs are not received, the CANopen safety status becomes "Not in progress" and the mapped variables freeze at the last value detected. I want to understand if it was possible to set the variables connected to the SRDOs to take a default value (e.g. zero) in the event of a CANOpen error during reception.

Post by struccc on HTML5 Controls - string(>80) values ^{CODESYS Forge talk (Post)}
Dear all, does anyone have experience with HTML5 controls recently? CODESYS 3.5.20.30 / Visualization 4.6.0.0 I'd like to create a simple lightweight text editor, with proper multiline handling, cut & paste, scrolling, etc. And it seems to work fine, just have problems with strings longer than 80 bytes.... Declaring a variable sText1 : STRING(8000) and referencing it in the HTML5 Controls corresponding value property works perfectly one way: the code receive the data as a string (See log1)... (Note TypeID 1000...) Also sending back the data (seems to work (See log2) except it doesn't change the value of the bound variable. Probably the issue is with using SendSimpleValue method... Naturally, I could do a workaround, but maybe there is a more standard way to implement this... Please let me know if you have any suggestions.

Post by sigurdrb on Read codesys version in the codesys application ^{CODESYS Forge talk (Post)}
Hi! I want to read the codesys version into the project, so I can highlight it in the SCADA system. VAR dwVersion : DWORD; END_VAR SysTarget.SysTargetGetVersion(pulVersion := ADR(dwVersion)); This gives me the value 100859909. I tried to search ths up and found som older post (https://forge.codesys.com/forge/talk/Runtime/thread/a55981ff4d/) that said each 4 bytes reads a number in the version. Example is 50662666 = 16#03050D0A which reads to V3.5.13.10 When I run this code I get the value 100859909, which I cant translate to anything meaningful. I am running it on Codesys V3.5.19.70. Help appreciated!

Post by peterkcontrols on Copying 2 byte word to output ^{CODESYS Forge talk (Post)}
Hello. I am using codesys 3.5. I would like to know if it is possible to set a variable to an output without declaring in. I have defined a STRUCT and within this struct I have a Struct for inputs called I and a struct for outputs called O. I have declared a variable of the type of this Struct, I would like to set or alias the value in this variable to an input/output value of an IO block that has a module on the ethernet tree. Is it possible to copy the contents of %IW0 -> STRUCT.I ? The size of both of these is 2 bytes. I understand that I can declare a variable with the input like Input01 AT %IX0.0 : BOOL; However how can I make STRUCT.I.D00 AT %IX0.0? Is this possible? Thanks

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 stuartjr on Disabling forcing of specific variables ^{CODESYS Forge talk (Post)}
I also thought that if I had logic writing a value to this variable, then it would override the force anyway, since I thought that the force request was only applied at the beginning and end of the PLC scan. But this doesn't seem to be the case, the force persists throughout the logic regardless of what I write to the variable with logic

Post by installwhat on raspistepper error after install ^{CODESYS Forge talk (Post)}
from another post on this forum .... In your library project select Project -> Project Information. On the Properties table remove the "LanguageModelAttribute" Value "Qualified Access Only". This will allow you to access the object without qualifying the access. ...... I guess they've compiled it the library with that setting and now I need to mess around with versions.
