Post by schnepper on Minor UI bug: cannot create SFC POU after creating a Function POU ^{CODESYS Forge} ^talk ^(Post)
After creating a Function POU, it is not possible to then create an SFC POU. Steps to recreate: * Create a new Function POU. SFC is not allowed for Functions, so SFC does not show in the Implementation language dropdown. * Click Add Object -> POU... Function is selected for Type. * Select Program * SFC is not present in the Implementation language dropdown

Post by ndzied2 on Rounding error in simple addition ^{CODESYS Forge} ^talk ^(Post)
This is a consequence of how computers store floating point numbers. 0.1 cannot be exactly represented in a computer. This is not a CoDeSys thing. Here is a link to a converter to show you the exact value that is represented when you use a REAL data type (which is a 32 bit float). https://baseconvert.com/ieee-754-floating-point If you really need to keep track of 0.1 increments. use INT OR DINT and then add 1 each time and assume that there is one decimal place.

Despite working on it for days, I haven't achieved any results. I followed the necessary steps one by one as mentioned in the file you sent, but there hasn't been the slightest change. I couldn't find the step you mentioned "Set the 'Can Board Type' to PCAN USB" in the Word document. There is no such setting anywhere I looked. Is there a more detailed explanation available, or can you explain it in more detail? What am I missing?

Post by andrej on Write to File on soft PLC winV3x64 ^{CODESYS Forge} ^talk ^(Post)
Hello all, I would like to store some data in text file. I use the soft PLC Win V3x64, on Windows 10. I use the SysFile Library 3.5.17.0. If I store the file directly in the in the directory of the PLC i.e. in '/CODESYSControlWinV3x64/E1FA7ABE/PlcLogic/LogAU.txt' the file is correctly filled with the data. However, If I use an absolute path to a different directory no data is stored in the respective file. Despite the fact that the respective file exists and the Filehandler is correctly opened (see in picture _fdSysFHandle <> -1). // sFileName : STRING := 'LogAU.txt'; // STORES FILE IN ../CODESYSControlWinV3x64/../PlcLogic/LogAU.txt' sFileName : STRING := 'C/Temp/LogAU.txt'// DOES NOT WORK --------------------- // FILE DESCRIPTOR _fdSysFHandle := SysFile.SysFileOpen( szFile:= sFileName,am:= SysFile.AM_APPEND,pResult := ADR(_Result)); Does some have an idea where the problem is, resp. how I can get store a file in an arbitrary directory. Thanks a lot and kind regards Andreas

Post by toffeebonbon on EL7041-0052 - does it run with EL7041 SoftMotion? ^{CODESYS Forge} ^talk ^(Post)
Good morning everyone. In my setup I am trying to use a couple of EL7041-0052 (the EL7041 variant without terminals for an encoder) to run stepper motors without feedback. When using the softmotion drivers for the EL7041 (Rev22 and Rev24, even selecting external feedback type doesn't work) the device log shows warnings for the corresponding hardware: "SDO write error 0x1 -> 0x8012:0x08 eError 0x1 AbortCode 0x6090011". 0x8012:0x08 is the register for the Feedback Type. My best guess was setting the the register value in the start parameters to zero, but the result is the same. What else can I try to get the hardware to work? I have screenshots attatched showing the running fieldbus and the log messages. EDIT: One clarification: the "device log" that shows the error is the PLC, not the ethercat terminal. The log of the terminal itself shows neither errors nor warnings. BR Robert

Post by manuknecht on High Cycle Times for SoftMotion_PlanningTask when using AxisGroup ^{CODESYS Forge} ^talk ^(Post)
Hello all I am using an AxisGroup with the Gantry2 Kinematics to move a 2D-Gantry system. When creating the AxisGroup, the SoftMotion_PlanningTask is created automatically with a cycle time of 2 ms in my case. I realized that the maximum cycle time of this task can spike to very high values (up to 60 ms) at lower speeds of the motion, leading to synchronization issues and errors on the axes. The same behaviour - though not as drastic - can be observed with virtual axes too. Is this behaviour intended or to be expected? Can the cycle time or type of the SoftMotion_PlanningTask be changed to prevent these errors? Or is there another fix for this issue? I tried changing the cycle type to Freewheeling, which solved the synchronization issues, but caused an error on the AxisGroup after a while, reading SMC_CP_QUEUE_UNDERRUN. Thanks in advance and best regards Manuel

Hi, I'm trying to monitor a specific PGN which I have it sending a pulse every 500mS Problem: Using the Watchdog for the ECU does not really help me as I have multiple instances with separate PGNs, if a PGN goes ghost, the ECU watchdog won't be flagged as the others will be running. I found the J1939.ReceiveWatchdog & J1939.ReceiveParameterGroup function blocks and they seem like a good solution for my problem, I just can't get them to work from my understanding you just build the J1939.ReceiveParameterGroup once and then connect it's output to the J1939.ReceiveWatchdog, here's my CODE for the setup HEARTBEAT_TIMER(IN:= TRUE, PT:= T#1000MS); //turn-on delay because of initialization race IF HEARTBEAT_TIMER.Q= TRUE THEN Glob_Var.DisplayReceive.xExecute:= TRUE; Glob_Var.DisplayReceive.itfECU:= Valve_X; Glob_Var.DisplayReceive.dwPGN:= 65511; Glob_Var.DisplayWatchdog.xEnable:= TRUE; Glob_Var.DisplayWatchdog.itfParameterGroup:= Glob_Var.DisplayReceive.itfParameterGroup; Glob_Var.DisplayWatchdog.tTimeout:= T#1500MS; END_IF Notes: Glob_Var.DisplayReceive is of type J1939.ReceiveParameterGroup Glob_Var.DisplayWatchdog is of type J1939.ReceiveWatchdog The above code is done once and not cyclically I'm monitoring Glob_Var.DisplayWatchdog.xError cyclically

Post by mubeta on parker servo and position ^{CODESYS Forge} ^talk ^(Post)
In general, drives have parameter sets to adjust behaviour in such cases: position recovery, adaptation with resistant torque, out-of-position window failure, etc. (Much depends on the type of configuration set for the axis: positioner, speed controller, torque controller, etc.). I have used that type of drive very little, in only two cases and a long time ago. To tell you what is normal is impossible. I know by reputation they are very simple objects, without too many pretensions and adjustments possible. Try running traces by monitoring actual position, motor current, torque and following error. These are the most sensible curves to understand what is going on. Maybe by fine tuning the motor tuning, the current controller or the speed controller you will get something closer to what you want. For example, from DS, the motor has a standstill torque of 3 Nm. Observe with traces whether this is effective: motor current trend. And afterwards, when you have your own accurate picture of the situation, you can also hear from the product's local support to see if you can steal a few more things from it performance-wise.

Post by paulorb on STRUCT AT %MW1000 ^{CODESYS Forge} ^talk ^(Post)
Hi I am trying to use STRUCT to parse commands from Modbus/TCP, Modbus client will fill the bytes related to a specific command (type, parameters), then PLC (Codesys) will access the command parameters. A STRUCT will simplify a lot the process of parsing the data, so I don't need to parse byte per byte, address will be mapped to a struct and I can use it for parsing the data. From what I understood, the compiler does not allow me to specify the location of the struct for a %MW register. VAR_COMMAND AT %MW1002: structGenericModbusCommand; This will throw: Bad declaration, use '%ML' for 'structGenericModbusCommand' variable But If I change it to %ML, when you go online you see that it is actually allocating the struct in another memory address. When we go online, on GVL we can see: VAR_COMMAND. structGenericModbusCommand %ML1002 commandType COMMANDTYPE %MB8016 ... %MB8020 I am not specifying a pointer or a reference it is a struct type, why is it mapping to a %MW location (random one). How can I control where it is mapping to? I need a consistent way to map STRUCT to specific modbus address. Is it possible? Thanks, Paulo Note I am using a Codesys OEM: Schneider Machine Expert Logic Builder (M241)

Post by macros8 on Translation - How to get text as reference in Frames translated? ^{CODESYS Forge} ^talk ^(Post)
Hi, thanks for the link. Maybe I create elements in incorrect way. I always use Interface Editor to create variables which are used inside element (see pics). After that I place element in my visu and use Reference property to link variable or set the value. In that case the value of string is not transferred to general text list for translation as I mentioned before. Do I have to all properties which influence behavior of my element create in Frame configuration instead? What´s the difference to the Interface editor? Thanks a lot. M.

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 sumit on Not able to see input data coming from eip adapter on codesys ^{CODESYS Forge} ^talk ^(Post)
dhumphries, I changed the datatype this time from BYTE to USINT (because that's what my adapter is sending: array of uint8_t). The text "New Help String" you saw in previous screenshots is just the description of the input/s (it can be anything). I also looked into the logs (see attached) for that ! sign next to the device, I found that connection is being timeout. I tried some suggestions from online such as increase the RPI but still got connection timeout issue, also by changing the datatype, I still don't see incoming data from the adapter, although its visible on wireshark. thanks,

Post by phoward131 on Text List Fallback Value ^{CODESYS Forge} ^talk ^(Post)
I am relatively new to Codesys and I'm trying to develop an HMI that displays what mode a particular device is in based on an integer value. I am currently using dynamic texts with a text list which works fine but I am looking for a way to display a particular string (ie 'Unknown') when the index doesn't match any of of the indices in the text list. I can enter 'Unknown' in the text property of the text field element which works as expected but it displays the single quotes on the visualization. How can I escape these quotes to simply display the word Unknown? Thanks!

Does anybody know how to get a specific text from a text list within a program. Obviously it works in a visualization, but because I will have an HMI that has it's own system and I will have to send variables to this HMI via an OPC UA connection, I need to be able to get a text into a string. I tried using the VisuElems like this, but it only returns an empty "" and nothing else. IF trig THEN sText := VisuElems.cmpDynamictext.DynamicTextGetDefaultText(ADR(sTextList), ADR(sAlarmID))^; //sText := VisuElems.cmpDynamictext.DynamicTextGetText(ADR(sTextList), ADR(sAlarmID))^; trig := FALSE; END_IF Any help and idea is highly appreciated because I am getting desperate here.

Thank you so much. This worked. Waht im trying to do here is to automatically tag each sensors, valves and so on. There is a preatty nasty tag system i working on. "_320" is not alloved. I can have a tag "+4f=320.004-RT001V" In codesys I want to build the FB in folders. -4f | --320 | --001 This is the system structure. Inside here is all of the sensors and so on. But with Codesys, I cannot tag this like this. So what I'm trying to do now is to Make a folder for the building "4f" and one for the system "320", and a POU _001. Is there a way in init to get folder names?
