Post by sturmghost on Mimic behavior of the visualization button element with a custom button ^{CODESYS Forge talk (Post)}
Im wondering how Codesys is doing the mouse event capturing with their visualization button element? If you add such a button without configuring any input configuration event (like OnMouseDown) or button state variable and then click on the button, the button changes to the visual pressed state and back if you release the button (so they must react to an OnMouseDown event). But how? If I try to mimic this behavior with my custom button visualization element (like a basic rectangle) I need to use an input configuration event to change the color of the button (to make it look like the button was pressed on OnMouseDown event). When I try to add this button via a Frame-Element to my main visualization page I'm unable to use an input configuration event on the Frame-Element because the input configuration event on the button element won't be evaluated anymore (it seems like you can't stack input fields, e.g. invisible input elements, onto each other). Hence the button is not shown pressed anymore. How they do it?

Post by andrax on CodeSys Raspberry pi I2C driver not found ^{CODESYS Forge talk (Post)}
Hi, Communication with the ADS1115 is actually simple. 1. write config 2. write address pointer 3. read conversation register The ADS1115 works like a multiplexer. This means that you do this individually for each channel that you want to read. e.g: Channel 1: write config > write address pointer > read conversation register Channel 2: write config > write address pointer > read conversation register Channel 3: write config > write address pointer > read conversation register Channel 4: write config > write address pointer > read conversation register then you start again from the beginning You can also omit individual channels or read only one. It doesn't matter. I have written the driver so that I can also use it on the TCA9548. The driver is from Stefan Dreyer. In your case, the driver works and communication with the ADS1115 is running. As you can see, the cfgWrong:=FALSE If you could not write or read data, cfgWrong:=TRUE; This means that either something is wrong with your ADS1115 or you have connected something incorrectly. Question: what voltage do you want to measure?

Post by edvard-munch on How I can get "Done flag" for "Modbus Slave Channel"? ^{CODESYS Forge talk (Post)}
This is from 10 years ago, I know. But I have been using (SLAVE_DEVICE.iChannelIndex = CHANNEL_NUMBER) AND (SLAVE_DEVICE.xDone) I suppose that it shows xDone for the channel that shows up in the iChannelIndex at the same cycle? It seems to be working properly for two devices that I have been using it before But now I have another device and using two write channels, for one register each. One channel works properly and returns DONE flag When another channel is triggered, I see that it shows up in iChannelIndex, but flag DONE not received, but no Error for the channel. Also, when i check the register in the device it's evident that data has been transferred. Is this could happen sometimes with CODESYS, so DONE flag not received? Or this is a problem with a given device? With this certain register

Post by canplum on Codesys 3.5.21 fails to copy file to USB ^{CODESYS Forge talk (Post)}
Although I have set in /etc/codesyscontrol/CODESYSControl_User.cfg the [SysFile] PlaceholderFilePath.1=/media/pi, $usb$ PlaceholderFilePath.1.View=1 PlaceholderFilePath.1.Volatile=1 I am not able to copy a file to this directory defined by the placeholder. Neither SysProcess.SysProcessExecuteCommand2 nor SysFileCopy nor FileCopy is working. If I try to copy the same file to /home/pi all is working fine. I also can create and open a different file by using SysFileOpen. I don't understand why the system allows to open (create) and write files into that directory but doesn't allow to copy into it. Obviously there is a rights problem with the USB drive. I have already set the permissions to drwxr-xr-x 2 and the user to pi but without any success. With 3.5.16 I never had such an issue. Is there anybody with some hints how to solve that problem? Cheers, canplum

Post by danieldiaz on Problem with FB execution ^{CODESYS Forge talk (Post)}
Hello everyone, I've been working on a system which needs an error function, with this purpose I've created a FB programmed in LD, after debugging I run the simulation. It seems that the variable linked to a coil doesn't change the value when the contacts are associated to input variables. When I use internal variables the logic works properly. I don't know if the problem is related to the variables definition or with the logic program. As you can see in the image, I1 and I2 are variables declared on the FB, the rest are input variables. If I force the eStop and Reset signals to TRUE the coil value should change, but it doesn't. However in the second network if I1 is TRUE the coil change to TRUE as it has to be. To sum up, my doubt is why that coil doesn't change its value? I would like someone to shed a light on this. Thanks!
