Post by rtlman on Scan devices hangs CODESYS ^{CODESYS Forge talk (Post)}
Hello, I have a problem that randomly appeared today. When trying to scan a network adapter in "Deploy Control SL" the whole program hangs and needs to be restarted. I have been running "CODESYS v3.5 SP21 Patch 3" for a while and it has worked without any issues until now. I've tried upgrading to "CODESYS v3.5 SP21 Patch 4" with the same result. I've not made any system settings recently that im aware of which could cause this. Has anybody had similar a issue?

If you use putty or any ssh client does this work to login to the plc?

I'm building up a 2nd PC to match an existing developer PC. Installed the same SP and Patch levels but when I open a project that was created on the existing PC, Codesys complains that it's not the same version. Attaching a screenshot..... What else is there to match? Also, can all of the libraries that are on the existing machine be copied from it to the new machine and if so, how? (So I get the same versions) Which files/folders do I copy? Thanks! -Farren

Open the CODESYS Installer. Create an export file from your current PC from your current version. Then on the other PC Open the installer and install a new version based on the same essentials version, but additionally select the export file which you have created on the first PC. Or just install (import) it within the already existing version. For the installer, you can install it from: https://store.codesys.com/en/codesys-installer.html For help see: https://content.helpme-codesys.com/en/CODESYS%20Installer/_inst_install_setups_and_addons.html On PC 1, save the project as projectarchive (which will then include all the libraries and devices). Then extract this projectarchive on PC 2.

Post by blitz on SMC_ERROR SMC_CGR_INVALID_POSPERIOD ^{CODESYS Forge talk (Post)}
Codesys - SMC_ERROR SMC_CGR_INVALID_POSPERIOD - Invalid modulo period less than or equal to zero or greater than half the bus bandwidth. Has anyone seen this error and actually understands what it means and how to get rid of it? I tried to work around it by reducing the number of increments on the drive but then the drive itself starts throwing errors.

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 bertus on Can't get SMC_SmoothPath to work ^{CODESYS Forge talk (Post)}
Hi Georg, thanks for your time. What is the value of D_ANGLE_TOL? It is set to 0.01. Do you need the assignment bAbort := NOT bDecoder? Does it help to leave it out? This seems to make no difference. Any errors (e.g. SMC_SmoothPath.Error/ErrorID) or PLC log messages? No errors or log messages. What if you comment out SMC_SmoothMerge and SMC_LimtiDynamics, is corner smoothing still not working? Indeed. Is bDecode written from a different task (e.g. visu)? Then I would recommend to assign to a local variable (bDecodeLocal := bDecode) and use that for all FBs. Otherwise, FBs might see different values of bDecode in a single cycle, which will cause problems. It is a local variable, written from a state machine inside this program. But there is new information: During some trial and error, I tried skipping "stage 2: merge short linear segments" (SMC_SmoothMerge). And suddenly it rounds the corners, see attached image. Looking a bit closer, I noticed that (with the original program) after a download (cold start?), it in fact did round the corners, but only once. Ever next cycle in which the NC program was executed, the corners where not rounded. Not sure if there is any relation, but SMC_SmoothMerge is also the only FB which has no bAbort input. Perhaps I need to reset it (or any buffers) by other means?
