Post by bertus on Can't get SMC_SmoothPath to work ^{CODESYS Forge talk (Post)}
Hello all, I am trying to run a XY trajectory from a static G-Code file. Everything works except the smoothing/blending of the corners. My setup: Codesys v3.5sp18 Raspberry Pi 4 CODESYS Control for Raspberry Pi SL, using demo license. Zero axes (only using the interpolator). The order of processing for my decoding is: SMC_NCDecoder (ok) SMC_SmoothMerge (ok) SMC_SmoothPath (not ok) SMC_LimitDynamics SMC_CheckVelocities I created following instances and buffers: fbNCDecoder: SMC_NCDecoder; fbSmoothMerge: SMC_SmoothMerge; fbSmoothPath: SMC_SmoothPath; fbLimitDynamics: SMC_LimitDynamics; fbCheckVelocities: SMC_CheckVelocities; aNCDecoderBuffer: ARRAY[0..49] OF SMC_GeoInfo; // buffer stage 1 (fbNCDecoder) aSmoothMergeBuffer: ARRAY[0..19] OF SMC_GeoInfo; // buffer stage 2 (fbSmoothMerge) aSmoothPathBuffer: ARRAY[0..99] OF SMC_GeoInfo; // buffer stage 3 (fbSmoothPath) aLimitDynamicsBuffer: ARRAY[0..39] OF SMC_GeoInfo; // buffer stage 4 (fbLimitDynamics) My original G-Code file has a lot of short G1 elements but this example, I reduced it to a simple square: N000 G51 D10 N010 G38 O1 N020 G00 X0 Y0 F50 E1000 E-1000 N030 G01 X0 Y-37.5 N040 G01 X-75 Y-37.5 N050 G01 X-75 Y37.5 N060 G01 X0 Y37.5 N070 G01 X0 Y0 N080 G50 N090 G39 O1 In the Codesys CNC settings, I have these instances activated: SMC_SmoothMerge SMC_SmoothPath SMC_LimitDynamics SMC_CheckVelocities And with those settings (and the path-preprocessing button actived), the G-Code viewer shows the square with nicely blended corners (see attached picture). However, when running it on the PLC, it doesn't blend the corners at all. Below the relevant part of my code. The process is started with bDecode. // stage 1: decoding G-code fbNCDecoder( ncprog := square, bExecute:= bDecode, bAbort:= NOT bDecode, nSizeOutQueue := SIZEOF(aNCDecoderBuffer), pbyBufferOutQueue := ADR(aNCDecoderBuffer) ); // stage 2: merge short linear segments fbSmoothMerge( bExecute := bDecode, poqDataIn := fbNCDecoder.poqDataOut, nSizeOutQueue := SIZEOF(aSmoothMergeBuffer), pbyBufferOutQueue := ADR(aSmoothMergeBuffer), piMaxDifference := PI_MAX_DIFFERENCE, usiMaxDegree := 5, wFeatureFlag := 1, wAdditionalParamNumber := 0, dMinimumCurvatureRadius := D_MIN_CURVATURE_RADIUS ); // stage 3: smooth corners fbSmoothPath( bExecute := bDecode, bAbort := NOT bDecode, poqDataIn := fbSmoothMerge.poqDataOut, eMode := SMC_SMOOTHPATHMODE.SP_SPLINE5_MIN_CURVATURE, eAddAxMode := SMC_SMOOTHPATHADDAXMODE.SPAA_NONE, nSizeOutQueue := SIZEOF(aSmoothPathBuffer), pbyBufferOutQueue := ADR(aSmoothPathBuffer), dAngleTol := D_ANGLE_TOL, bSymmetricalDistances := TRUE, bImprovedSymmetricCuts := TRUE ); // stage 4: keep acc/dec and velocity within limits fbLimitDynamics( bExecute := bDecode, bAbort := NOT bDecode, poqDataIn := fbSmoothPath.poqDataOut, wAxis := 16#07, nSizeOutQueue := SIZEOF(aLimitDynamicsBuffer), pbyBufferOutQueue := ADR(aLimitDynamicsBuffer), bIncludePathSettings := TRUE, dMaxVel := 2500, dMaxAccDec := 10000 ); // stage 5: check the path speed fbCheckVelocities( bExecute := bDecode, bAbort := NOT bDecode, poqDataIn := fbLimitDynamics.poqDataOut, dAngleTol := D_ANGLE_TOL); pathQueue := fbCheckVelocities.poqDataOut; // repeat until MaxDuration ... Any idea what I'm doing wrong? Is smooth path supposed to work at all when using a demo license? Thanks.

Post by naks on Change IP address from IEC code ^{CODESYS Forge talk (Post)}
Hi, I'm working with wago 750-8212 controller. I want to change the IP address of the Ethernet adapter from webvisu. I have read some other threads in this forum and I have tried the following: Added the following text to the config file CODESYSControl.cfg: [SysSocket] Adapter.0.Name="br1" Adapter.0.EnableSetIpAndMask=1 Used the below code : IF xUpdateEthernet THEN Ethernet.Enable := FALSE; Reconfig ( xExecute := TRUE, itfNode := Ethernet, eError => ErrorReconfig, xBusy => xBusy, xDone => xDone, xError => xErrorReconfigure); IF Reconfig.xDone THEN ErrorCode := Ethernet.UpdateConfiguredIPSettings(IpAddress := NewIp, gateway := newGateway, subnetmask := newSubnetmask); END_IF IF Reconfig.xDone OR Reconfig.xError THEN reconfig(xExecute := FALSE); END_IF Ethernet.Enable := TRUE; Reconfig(xExecute := TRUE, itfNode := Ethernet ); END_IF I could change the IP address but when i restart my Controller then the IP address resets to the original, Is there anything I have missed, what else can i try ? Thank you in advance.

Post by alimans on OPC-UA Server, Symbol Set: Raise an error: Object reference not set to an instance of an object. ^{CODESYS Forge talk (Post)}
Hi everyone, I just created a very simple library without any code and, added it to my very simple project. after adding this library, I get an error when I try to open "Symbol Set" in "OPC UA Server" in "Communication Manager". Here is the code of my POU in the library: FUNCTION_BLOCK POU VAR eCommand : (CMD_NONE:=0, CMD_RESET:=-1) INT := CMD_NONE; END_VAR Attached is the error that I get. I also noticed that by removing the enumeration variable above (eCommand), I can open the "Symbol Set" again. Anybody has any idea why this error is raised and how could I use enumeration variables without error in "OPC UA Symbol Set"?

Post by opineiro on How to manage variable types larger than 64 bits - Ethernet/IP ^{CODESYS Forge talk (Post)}
Hi there, I have a Keyence bar code reader connected to my plc through Ethernet/IP. The Bar code is 20 digits long (like 30100790020493036016), the scanner reads it correctly (I can verify that through the keyence software) but when it sends it through ETH/IP, it doesn't fit into a 64 bit variable and it trunks the data.(I've tried ULINT and LWord without success). When I loaded the EDS file, the read variable was defined as a byte with 128 bits length, which is quite strange for me. (see attached picture) How do I manage this variable? Thanks!

Post by bjarne-pagaard on Global Variables ^{CODESYS Forge talk (Post)}
Old thread, I know - but it still has good answers. I would like to add a bit of info to it, as I was having a problem that lead me to this thread, but didn't give an exact answer. I am porting a project to a different PLC architecture. (Wago PFC300) A GVL named 'GVL' in the POUs section of my project was shadowed by a PLC-specific library in the Application->Library Manager. So all the existing references in the device specific code to 'GVL.something' would not resolve. Right-clicking the GVL in the code and 'Go to definition' would point me to the library in the Application Library Manager. All I had to do from there, was right-click the library, and set the property 'Only allow qualified access to all identifiers' in the library.

Post by ignat on Change date range of Trend ^{CODESYS Forge talk (Post)}
Hi ryusoup, looking for the same functionality. I tried to use your code but couldn't figure out all the details. to enable Listener should it be called once or cyclically? the listener should be called with the intance of FB which you described? should it be this instance to be called cyclically too? I tried to make it simpler, just force the uiYear/uiMonth etc. but couldn't make it work. Could you please share some details how the whole struckture looks like? Would be great if you share an example UPD: found the issue. Your code works. Thanks for the posts

Post by alexgooi on Function Blocks and arrays of function blocks ^{CODESYS Forge talk (Post)}
Hi Jack, I think you have to look at a FB in a different way. A Function block (Class) can contain its own data. In other words don't define loose data in your GVL, but define a instance of a FB (Object) in your GVL: Example: Function_Block Basic_Class VAR_INPUT Open_Command: BOOL; END_VAR VAR_OUTPUT Opened: BOOL; END_VAR if Open_Command then Opened := TRUE; ELSE Opened := FALSE; END_IF Global Variables Objects: ARRAY[1..100] OF Basic_Class; //Here you ar defining you objects END_VAR In your code you can directly acces the data and couple it to the IO: GVL.Objects[1].Open_Command := %IX0.0; %QX0.0 := GVL.Objects[1].Opened; //To call the code itself use: GVL.Objects[1](); If you want to take this a step further you are also able to add methods and properties to the FB/Class end thereby creating a OOIP program

Post by ewi04 on How to upload application file to remote controller (offline) ? ^{CODESYS Forge talk (Post)}
Thank you very much for your time and replay! Sounds like a good idea. Unfortunately, I have no other option to run the code from the running plc. So, I can’t stop any services. If anyone has the same problem, I've gotten a little closer to understanding it: Sometimes the copied files are empty after the restart. The update code checks if there are any empty files. Before I turn off the device, everything is okay. But after starting, some files are suddenly empty and that cause the problems. I don't know why this happens.

Post by dkugler on build (F11) / generate code using a python script file ^{CODESYS Forge talk (Post)}
thank you very much! I found the generate_code methode, but struggled with the primary and active_application. With this expample I will be able to play around. If the code generation takes a minute or more I often switch to other programs and don't notify the process is finished. So now I'll get an alert and will switch back immediately. My next little project will be, to beep different if there are errors and a seperate script to do the download incl. the user management data base without stopping at the dialogs asking for onlinechange/complete download and overwriting an existing database and as goody, play a beep/sound again.
