Post by imdatatas on C0138: No matching 'FB_Init' method found for instantiation of VisuClientObjectMgr ^{CODESYS Forge talk (Post)}
Hello everyone, I downloaded the "Example: PLC Chat Net Base Services" example from the Codesys help site to review and try it out. https://content.helpme-codesys.com/en/CODESYS%20Examples/_ex_cds_plc_chat_net_base_services.html However, when I open and compile the example program with SP21 Patch2, I get the strange error message below regarding Visualisation component, and it fails to compile. " [ERROR] visuelems, 4.8.0.0 (system): VisuFbTabControl: C0138: No matching 'FB_Init' method found for instantiation of VisuClientObjectMgr " Are others experiencing the error "C0138: No matching 'FB_Init' method found for instantiation..." when trying to compile example projects created with older versions of Codesys with a later version of the IDE? How did you overcome this problem? Could you share your solutions? Regards, Imdat

Post by timvh on Codesys 3.5.18.60 – Application Loss and Persistent Data Corruption ^{CODESYS Forge talk (Post)}
Which device do you use? Does this have persistent memory (e.g. NVRAM) available? Maybe first ask your PLC vendor about the possibilities and how they advice to use persistent variables? If you have no NVRAM available, CODESYS will store the variables in a file when the device gracefully shuts down. But on an abrupt power failure, this is not possible. If you have no NVRAM and you want to use persistent variables, then consider using a UPS. In this case when the power is lost, the UPS can keep the power on the PLC which then can gracefully shut down. Alternatively use the Persistence Manager to store the variable values in a file e.g. only on change. See: https://content.helpme-codesys.com/en/CODESYS%20Application%20Composer/ac_pm_overview.html

Post by em1681 on Modbus RTU over 750-652 ^{CODESYS Forge talk (Post)}
Hi, It's my first time operating in Codesys 2.3, but I have done a good amount of Codesys programming, so I'm a little familiar. I haven't done a lot of RTU, but a lot of Modbus TCP. I don't have the PLC in my reach at the moment, but I'm trying to be a little ahead. We're adding the 750-652 module to read energy from a flowmeter over RTU. There will only be 1 slave. I attached pictures of my current hardware, PLC code, the register datasheet from the slave and the only modbus serial library I seem to have available. I'm uncertain if this will work. Any help or clarification on how things work will be greatly appreciated. Thanks in advance.

Post by alexgooi on Codesys virtual control redundancy ^{CODESYS Forge talk (Post)}
Dear Forum, I’m currently investigating the possibilities of Codesys virtual control (Linux). The research rig consists of a PC (Debian with real time kernel) with a docker server installed on it. The PC is communicating with a Remote I/O and I have to say the performance is great. The process in the container is running (soft) real time. Currently I’m checking if it is possible to replace physical controllers by remote I/O’s and run the Codesys applications on a docker server. If I’m going into this route the reliability of the server is very important (server down, complete installation down), is it possible to make the server redundant without needing 2 separate containers (including licenses), and maintaining the real time behavior? I’m not only expecting direct answers, if you have any idea or thought they are very welcome. Kind regards Alex

I can also add the kernel log messages from the same time. Seems like some kind of packet storm to the PLC?
