Post by tvm on Web Client (HMI) Disconnects from Webvisu (Weidmuller u-OS) ^{CODESYS Forge talk (Post)}
ok, that's different than our issue then. We're using Schneider Electric M262 PLCs, and we've had it where certain web browsers cause the web server to only allow https connections, but it's not recoverable with a refresh. It usually requires a power cycle or even a full firmware flash. Your issue might have more to do with the timing. I don't know if it helps you, but we normally run our visu task at 200mS, with an update rate of 200mS. Seems to work. I went through this: https://faq.codesys.com/pages/viewpage.action?pageId=112525371 but it really seems like trial and error.

Post by dsa28 on OPC UA subscriber not operational ^{CODESYS Forge talk (Post)}
Hi, Thanks for the reply. Please note that the information and links provided are related to OPC UA Client/Server. My problem was related to OPC UA Pub/Sub. In the end I have managed to establish OPC UA Pub/Sub communication between Codesys and TwinCAT systems. Keep in mind that OPC UA Pub/Sub example is not provided in the latest library version 1.1.0.0. The user needs to download the previous version to get the example. During the configuration I ended up with some doubts regarding the usage of IEC_ARRAY type in the dataset definition (see attachment). Can you please give more information on how to use this type? Many thanks.

Post by elsmart on Sequential read and triggering of Modbs RTU channels in application ^{CODESYS Forge talk (Post)}
Hello I need some help understanding how to use Modbus RTU (COM port) in Codesys enviroment. I defined a Modbus Server device (slave) in device tree and added some channels to read from (function 3). Also I set trigering mode to Application. I have a POU in which I want to trigger each channel one after the other something like this (C code for better visualisation): for (int i = 0; i < channelsCount; i++) { triggerChannel(channelsArray[i]); // Start transmission while(channel.xBusy); // Wait for transmission to complete } I have found ModbusChannel function block documentation but examples are scarce. I don't understand how rising edge triggering works. What would be the best solution for achieving sequntial channel triggering? What is the common way to read multiple Modbus channels once every time a specified POU is executed?

Post by alexgooi on Licensing info not available. ^{CODESYS Forge talk (Post)}
Thank you for your quick response, I have updated to the 4.17.0 (Virtual control and the license server). Now I am able to see the softcontainer from the Codesys IDE. But when I want to activate the license I get the following message: Licensing info not available. The device does not support this service (See picture). I then tried to active it via the WBM service like you suggested. But when I try this is get an error (see picture for error). I also tried to put RTS- in front of the serial number, but when I try this I get an error that the serial number is not correct. I think I'm getting closer, but I'm not there yet.

Post by egr99 on Modbus TCP Server connection is ESTABLISHED but all holding registers are value 0? ^{CODESYS Forge talk (Post)}
You're absolutely right. Sorry for that. In the meantime I wrote a Function block to handle the reads and writes to the different attached RTU-devices. It processes the parameter like (str_Modbus:=(usiSlave:=1, uiFC:=5, uiLEN:=1, uiOFFSET:=0, uiInterval:=500)) and the corresponding output, waits for the response and processes next request in a 5-state procedure. It's working for 2 gateways (stable without errors, although error recovery is included). But nevertheless it should be possible with the Channel definitions of Codesys. Much easier to maintain :)

Hey there, is there a way to extract any data out of a .library or a .compiled-library file? Do you have any tools or a description of the binary or something like this to get for example the referenced libraries of a *.library file or any other stuff? Thx in advance M.

When trying to use the Visualization ToolBox, no objects appear and the following error appears. Could you tell me what this error could be? The element of type 'VisuFbElemImage' could not be updated. Reason: Index was outside the bounds of the array. Can anyone tell me what this error is?
