Post by abrarsk on SysCom Library Usage ^{CODESYS Forge talk (Post)}
Hello all, I am facing issues with using SysCom library. With SysCom23 library things were simple but since we are migrating to 64bit systems, I am writing a Porting program. With SysCom23, opening the comport was as simple as providing the ComPort no. which returns the Handle as a DWORD. dwHandle:=SysComOpen(Port); But the new library is a bit different. It is asking for 2 input parameters to open the Com Port - Port Number and POINTER to RTS_IEC_RESULT IF hCom = 0 THEN hCom := SysComOpen(ComSettings.sPort, ADR(pResult)); How should I use the RTS_IEC_Result? I can find RTS_IEC-REUSLT under SysType2Interfaces of SysCom library. Also, can someone give me a general understanding of this RTS_IEC_REULT and RTS_IEC_HANDLE, etc.?

Post by pernockham on Linking to IO during runtime with hot swap? ^{CODESYS Forge talk (Post)}
I have a project where a single PLC shall control multiple nodes (up to 10 units?) with IO connected through profinet. Ideally each node should be identical however with time I see situations were different setups/configurations will be used. Codesys PLC (GVLs) |Profinet | |--PNIO-node-1--| | | AIO, | | DIO, | | CNT etc. | |--PNIO-node-2--| | | AIO, | | DIO, | | CNT etc. Ideally I think of a configuration through yaml/xml-files (the assignment/linking of the profinet nodes towards GVL-variables in the PLC as well as scaling, channel configration etc.). Would be grateful if someone could suggest library/-ies that can handle the following: - Verify what IO is connected to a device/node. - Hot-swap/assign link for IO towards GVLs, either automatically or through a HMI.

Post by dhumphries on Toggling Visualizations using HMI Physical Buttons ^{CODESYS Forge talk (Post)}
Nothing wrong with ladder, in a lot of applications it is simpler than ST or CFC, you're a lot less likely to have syntax issues in a ladder diagram than in structured text as long as you stick with traditional ladder elements. Your attempt was almost valid, but you tried to change the currentvisu variable using a blend of structured text and ladder, which isn't allowed. You need to use the MOVE operator and define the visualization name as a string on the input side and the visuelems.currentvisu as the target on the output side.

Post by janber0206 on Adding PLC to the List view resolves in Unknown Error ^{CODESYS Forge talk (Post)}
Hello, I try to add one of my PLC from the Gateways to the List view. The Gateway is shown me as online, also i have other remote tools to verify the Internet connection is working. I do the Network Scan and the Gateway shows up, i select it and click on "Add to Server". Then I type in Username and password and click on confirm. There it shows me the "Unkown Error", see screenshot. If I use the wrong credentials it gives me the error message for this. Other Devices work fine it's just this one. Greetings Jannis

Post by otbeka on CAA File Handling: "Read only" error ^{CODESYS Forge talk (Post)}
Hi, sorry for the late reply. After some investigation, the read-only error was being triggered by a FAT-fs filesystem panic on the kernel end, probably caused by unfinished write/reads causing corruption. I found this thread https://forge.codesys.com/forge/talk/Engineering/thread/e637d252b7/ which seems to give a solution of using SysProcess to send the 'sync' command to the console immediately following a write to prevent issues if power is lost or, in my case, if the unit is harshly power cycled. Indeed this seems to resolve the issue bar the worst possible edge cases.

Post by abuckie on Getting raw value as full resolution for ADS1115 ^{CODESYS Forge talk (Post)}
I just found this and I am getting a value larger than 16 bit, around 81000 something. I am reading a 5 volt value and I am using level shifters for the i2c bus. This is how I have the channel configured: ADS1115.usiAddress := 16#48; ADS1115.ChannelConfigs[0].Active := TRUE; ADS1115.ChannelConfigs[0].PGA := FSR_6144mV; ADS1115.ChannelConfigs[0].InputMux := Single_0; RawAnalogValue := ADS1115.Channels[0].Value; It looks like every value is a multiple of 3. Any idea where to look to fix this? I think i found what I want to change in UpdateChannels Channels[FChannelNo].Value := INT_TO_REAL(WORD_TO_INT(LValue) * GetFullScaleRange(ChannelConfigs[FChannelNo].PGA)) / 2048.0; I try to edit it but I can't, sorry if this is a basic question, I am new to CODESYS.

Post by andrej on Signing of Boot Application for Raspberry Pi ^{CODESYS Forge talk (Post)}
Hello all, I would like to sign my boot application for my Raspberry PI. I generated the X509 Certificate and loaded it to the raspberry. It is successfully displayed as trusted certificate. However, I cannot download and start the Application to the Rasperry, due to a signature mismatch.The error message is rather clear, but I still don’t see how I can fix the issue, since the certificates on the Controller seem to mach the certificate in the user profile. Could you tell me where the error is or which step I am missing. Many thanks and kind regards Andreas

Post by robpqs on Program from one PLC to other WAGO 750-8204 ^{CODESYS Forge talk (Post)}
Hello, You use the WAGOUpload tool. You can download it on the download center of WAGO. Make a backup and restore it on the new device. (if can check the remanent data to copy the persistent variables if necessary) You can also use a SD card, go to the WBM copy it the image to the SD card and restart the other controller on the SD card. In the WBM, copy it back to the internal flash. If you contact your local Wago office, they will more than probably help you. There is also a WAGO forum. RP,

Post by mahmutbeyaz on Create a Motion Profile ^{CODESYS Forge talk (Post)}
Dear All, I hope first to get notice and somebody answer my question. How can I create a motion profile with the axis following it (once or periodically)? As my research shows, Schineder has a UI-based (Motion Sizer) program that helps create a motion with different configurations, which is Codesys-based. I need to create a motion profile based on position, changing the speed. (i.e., 0-300mm moves with 300 mm/s, 300-400mm moves with 500 mm/s, 500-800mm moves with 1000 mm/s, and 800-0mm moves with 2000 mm/s). MC_PositionProfile does it time-based, which is not working for me as the axis may not stabilize the position in time, which may cause a big failure in the system.
