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.

You could create a DUT of the Type Union and add an array of 2 bytes + an Int. Then write the byte values in the array of the Union and read the Int. Or VAR iInt : INT; byHigh : BYTE := 2#1111_1111; byLow : BYTE := 2#1111_1111; END_VAR iInt := TO_INT(byHigh*16#100 + byLow);

Post by csu-chris on No file found ^{CODESYS Forge talk (Post)}
I'm having trouble getting started with the SysFile library. I tried copying and running the code found here: https://forge.codesys.com/forge/talk/Engineering/thread/f17c3d0e64/ Every time I try to run the file handle pointer returns: 16#FFFFFFFFFFFFFFFF <dereference of="" invalid="" pointer=""></dereference> I can see the file when I look in the Device -> Files window Any idea what I'm doing wrong?

Post by timvh on CAN Open Manager - varible of SYNC ^{CODESYS Forge talk (Post)}
You can enable "Sync Producing" in the configuration of the CANopen Manager. Then this manager will send a SYNC message every interval you set. Depending on your PDO configuration, the CAN nodes can send a PDO on every Sync (cyclic-synchronous). If this is not possible, then as alternative you can send a low level CAN message with COB-ID 16#80.

Post by atone on Change IO-Link Device Interface connected to a Profinet-Slave at Runtime ^{CODESYS Forge talk (Post)}
OK, I figured out that I can simply define all the sensors as 16 bytes IN/OUT, even if they are not all used. EDIT: The negative effect is that each bit is taken into account as an I/O for the license, even if not used.

Post by thierry-b on Blocking UDP ports 1740–1743 and 22350 to disable CODESYS network scan (startup + device discovery) ^{CODESYS Forge talk (Post)}
Hello, I am currently investigating the network behavior of CODESYS 3.5 (IDE + Gateway) in environments where the engineering workstation is connected to a very large /16 network. In such networks, the automatic device scan performed at IDE startup (and the manual “Scan Network” device discovery) can cause significant delays or freezes, due to the broadcast‑based discovery mechanism. After analyzing the traffic with Wireshark, I identified that the IDE uses the following UDP ports: 1740 – broadcast discovery 1741 – handshake / responses 1742 – fallback discovery 1743 – fallback handshake 22350 – additional runtime / gateway communication (WAGO, debug, extended discovery) To prevent the IDE from scanning the large /16 network, I tested blocking these ports in both directions (IN/OUT) on the network interface connected to the /16 segment (while keeping them open on the OT /24 network interface). Result: When UDP 1740, 1741, 1742 and 1743 are blocked on the IT interface, the IDE no longer sends any discovery traffic on that interface. The IDE still works normally on the OT interface (device discovery, online mode, download, etc.). Blocking port 22350 does not seem required to stop the scan, but I included it for completeness. My question: => Can you confirm that blocking UDP ports 1740, 1741, 1742, 1743 (and optionally 22350) on a specific network interface is a valid and supported way to completely disable the CODESYS IDE network scan on that interface (both at startup and during manual device discovery)? I am not trying to block communication with controllers on the OT network — only to prevent the IDE from scanning the large /16 IT network. Any confirmation or additional technical details about the discovery mechanism would be greatly appreciated. Thank you.

Post by pistola on How to change font and font color rectangle/or related object ^{CODESYS Forge talk (Post)}
Here is the help sections for visual elements rectangle. https://content.helpme-codesys.com/en/CODESYS%20Visualization/_visu_elem_rectangle.html Under "Font Variable" there is "Color" which is a Dword, you can make a variable that changes colour within your code to the color needed. Note the format for the Dword variable is: colorVariable := 16#TTRRGGBB Where: TT = Transparency 00-FF RE = Red 00-FF GG = Green 00-FF BB = Blue 00-FF https://content.helpme-codesys.com/en/CODESYS%20Visualization/_visu_animate_color.html

Post by viksym on How to get the motor scaling value from code ^{CODESYS Forge talk (Post)}
If anybody finds this in the future, I managed to do it like this: scalingValue := EncoderPulseCountPerRev / ABS(AxisName.fScaleFactor); No need to use MC_ReadParameter as I am able to read this value directly from the axis object. Using an absolute value of the fScaleFactor is there in case the axis is set as inverted, in which case it would be a negative value. I was not able to figure out how to get EncoderPulseCountPerRev programatically, but since all my servos use an encoder with pulse count per revolution of 16#800000, the final equation looks like this: scalingValue := 16#800000 / ABS(AxisName.fScaleFactor);

Post by mmoncada on Dinamically loading recipes ^{CODESYS Forge talk (Post)}
I'm having trouble with the initial loading of recipes. I can create them and load one or the other, but when the program restarts the recipes are not listed. I'm calling: RecipeManCommands.ReloadRecipes and then RecipeManCommands.GetRecipeCount which returns 0 recipes. None of the methods returns error and if i call them again after RecipeManCommands.CreateRecipe RecipeManCommands.ReadAndSaveRecipe getRecipeCount returns the number of recipes created. When i restart the system, once again they are not listed even though the recipe files are there. Any ideas? Martin Btw, Codesys 3.5 SP 16 Path 9
