Problems when I change something on the MQTT side

[famalicom0]

Hi All,

I'm trying to use this library to communicate with MQTT. Every time I change something in the MQTT program, on the PLC side, I need to force reboot in the update, otherwise I run the risk of sending the PLC into the shutdown state.
Is this a problem with the library?

Hello,
I do not have information about an issue when updating. Maybe you can share a quick example which causes the problem?

Maybe you can add the deactivation of the functionblocks to your program and check if the issues still exists.
The screenshot is taken from the examples shared with the library if you want to take a closer look.

Hello,

I was trying to use the TCP example with some changes according to my needs, I tried to put the Repeat code as you have in the example and it seems to work a bit better.

Now the PLC goes to service after some time

Hello,
the error in the logbook 6403 indicates that there might be an issue within the user application.
Check https://help.br-automation.com/#/en/4/diagnostics_support/sys_error/files/syserror_br2000_6403.htm
The modules marked by the logger are usually not causing the error but are affected by it.
Please check your implementations (foremost all pointer usage)
I'm unsure if I can help you without a closer look to the project.

Hello,

This only happens when we update the PLC and it has changes on the MQTT package.
After rebooting the PLC, it works as expected.
