Post by yannickasselin on MQTT QoS 1 & 2 ^{CODESYS Forge talk (Post)}
Using Wireshark, I can see that the broker sends the QoS 1 or 2 messages when Codesys MQTT client reconnects but they are just discarded and not acknowledged by Codesys MQTT Client. So the broker holds on to them and tries to send them back to Codesys every time the client reconnects but they are always discarded by Codesys. There really seems to be an issue with QoS 1 & 2 in Codesys. It really does not behaves like it should.

Post by pernockham on Persistence Manager: Config File not found? ^{CODESYS Forge talk (Post)}
Trying to utilize the persistence manager, but system do not write to file and do not create the config file. System is a Linux SL, version 4.13.0.0 Problems with persistence/config started when I had other problems to go online, I deleted the config file and the persistent files, but the system will not re-create them. I have tried to remove/re-install the "PersistenceManager"-module, create the folder-structure myself. And also reinstall the linux-runtime but its clearly not working. Any help appreciated.

Post by warrumungi on Opening a Dialog on a specific Client from ST ^{CODESYS Forge talk (Post)}
Hi Thanks, Manuel, for providing this solution and insight. I too had exactly the same problem as you did. While I did implement a custom filter, I'd also like to point out what jinlee mentioned above...I see no reference to VU.PublicVariables.Clients.Current anywhere?? In my case I only needed to show a dialog on a "master" client, not all the clients, so I filtered by IP address to do this.

Post by ben1 on How to write multiple coils (Modbus FC15) ^{CODESYS Forge talk (Post)}
When you say it does not work, does nothing happen or do you get an error? I have not used this function in codesys but from my past experience with Modbus I believe the coils need to be contiguous, which may be why yours is failing? Have you tried using Write Registers (16) to do the job? Or is their data in-between you do not want to edit in the transaction?

I did not able to receive the signal from Modbus RTU to Raspberry PI5 where I use the RS 485 serial connection.

Post by micik on PLCOpenXML Export/Import with Visualisation ^{CODESYS Forge talk (Post)}
I have noticed that Codesys doesn't provide option to Export any Visualization objects even though there is option to check to export VISU_TASK, which is strange because when Import in another empty project, user will end up with build errors. I understand that probable reason for this is that PLCOpenXML specification includes only "PLC" parts of the project (POU, PRG, variable lists, device ....), but not sure about it. Perhaps, there is some option to include visu objects also in the plcopen xml export list??

Post by bertcom on STRING conversions to DWORD ^{CODESYS Forge talk (Post)}
Good afternoon. I want to communicate with a Domino Industrial Printer using its Codenet protocol. The printer wants a series of Hexadecimal characters with no spaces or '00' characters. Because of that i chose the option to make the prefix and subfix for my code in a string. I have variable data in another string. With a complete program of a lot of CONCAT functions i eventually get the format of code that the printer accepts ( tested it with the hercules tool). Hercules String : 1B4F513030311B7532626C61636B04 The problem is : Codesys adds automatically 'code' to the code to show it is a string. Codesys string : '1B4F513030311B7532626C61636B04' The printer does not understand this. My idea is to convert the string datatype to an LWORD. I have no idea how to do this. I random types in STRING_TO_DWORD, as return i get 0. That didn't worked. Also on internet the explenations around string converting in codesys are very limited. If there in anyone who can explain me how to do it, i would appreciate it a lot ! Thank you!

Post by pedrorgd on SFC Exit Action during SFCReset Flag ^{CODESYS Forge talk (Post)}
I have an SFC POU with an SFCReset Flag that I use to restart it from the beginning. It works properly. During an Action Step I set one variable to TRUE and I reset it to FALSE during the Exit Action. My question is if this Exit Action will be activated -and the variable reset to FALSE- if I get out of the active step using the SFCReset Flag.

Post by konstantinoskr on AXIS Rollover ^{CODESYS Forge talk (Post)}
The MC_Home or MC_SetPosition requires a programm cycle to be completed. In my application the speed is approximately 120m/min and the programm cycle is 2ms. That means that i will have a 4mm loss on each Trigger of either MC_Home or MC_SetPosition. The best option is to change the value defined in the axis configuration. I tried the SMC_SetMovementType but it only works with the axis standstill or powered off. I need to be able to change it while the axis is moving.
