It seems you have 2 network interfaces. Did you try eth1? Did you already configure the IP address for this interface in Linux? If yes, then maybe undo this. - or only set eth0 in the Nic configuration without anything else (so no IP address, because this is already set in Linux). For more information about the Nic settings, see (probably already read it?): https://content.helpme-codesys.com/en/CODESYS%20Control/_rtsl_obj_deploy_control_sl_configuration.html PS, if you only want to run CODESYS Control SL, you don't necessarily need the Virtual PLC variant. You could also install and run the CODESYS Control SL Runtime in the Host operating system. This way you should also be able to access the serial port and directly access all ethernet ports. Maybe this is easier?

Post by etienneneu on loading delay with the option "check client animations and overlay of native elements" ^{CODESYS Forge talk (Post)}
Hello guys, I have the following problem with the Codesys visualization (4.6.0) and Codesys V3.5.20.20. I would like to use my own HTML5 elements for my visualization. To do this, I have to select the option “Support client animations and overlay of native elements” in the visualization manager. But with the selection of this option, the visu has a massive loading delay when changing frame content. This happens even if I have not even added HTML5 elements. However, if this option is deactivated, then changing the content of the frames works without any problems, it loads instantly. I have already tried to change various refresh rates but without success. Have any of you experienced this and been able to fix it?

Post by john-robinson on Limiting Memory Access of an Array to Within its Bounds ^{CODESYS Forge talk (Post)}
Recently we had an issue regarding some simple code to calculate a rolling average. The code indexes from zero to 199 to properly store the current input into a circular buffer which then allows us to calculate a rolling average: VAR input_5s : REAL; outs_arr : ARRAY[0..199] OF REAL; i : USINT := 0; END_VAR ___ //this code runs every five seconds, calculating a rolling average outs_arr[i] := input_5s; i := i + 1; output := OSCAT_BASIC.ARRAY_AVG(ADR(outs_arr), SIZEOF(outs_arr)); IF i >= SIZEOF(outs_arr) THEN i := 0; END_IF There is a simple bug in this code where the index will be set to 0 when it has surpassed the length of the array in bytes (800 in this case) rather than larger than the number of reals in the array (200). The solution here is simple, replacing i >= SIZEOF(outs_arr) with i >= SIZEOF(outs_arr)/SIZEOF(outs_arr[0]). In this example when the index increased to 201 and the line outs_arr[201] := input_5s was called, codesys arbitrarily wrote to the address in memory that is where outs_arr[201] would be if the array was that long. I would like to find a way to wrap the codesys array inside of a wrapper class that checks if an input is within the bounds of an array before writing to that value. I know how I would implement that for a specific array, I could create a method or class that takes an input of an array of variable length, ie. ARRAY[*] OF REAL, but I don't know how to make this for any data type. I am wondering if anyone has ever done anything similar to this, or has any better suggestions to ensure that none of the programmers on this application accidentally create code that can arbitrarily write to other locations in memory.

Post by mubeta on Some 'pathetic' errors in SoftMotion program ^{CODESYS Forge talk (Post)}
Hello everyone, I have a very simple program for the process, but it's driving me crazy and I can't see the problems I'm left with: Short topological description: Dual Core Berghof controller with softmotion runtime version 3.5.19.30; Two axes with servodrive on canopen bus, clocked distributed from master; Ethercat I/O node; 2 ms ethercat task, 2 ms canopen bus cycle time; I/O objects of the canopen master and canopen drives connected to the ethercat task cycle; Problem 1: Two separate programs each manage their own axis and drive, with separate state machines. A first axis moves primarily in velocity, except having to position itself absolutely at a predetermined point at the end of the job; the second axis, on the other hand, is a paper unwinder that changes, for each job cycle, from actions in absolute, relative, and cam displacement with the master axis. Well, the state machine of both axes was written in such a way as to call running the useful FB and change it on state change in this way: CASE i_stateMachine OF 0: o_Power(Enable := TRUE, bRegulatorOn := FALSE, bDriveStart := FALSE, Axis := o_PaperUnwinderAxis); o_MoveAbs(Execute := FALSE, Axis := o_PaperUnwinderAxis); o_MoveRel(Execute := FALSE, Axis := o_PaperUnwinderAxis); o_CamSelect(Execute := FALSE, Master := o_MachineAxis, Slave := o_PaperUnwinderAxis, CamTable := cam_PaperUnwinder); o_CamIn(Execute := FALSE, Master := MachineEncoder, Slave := o_PaperUnwinderAxis); o_CamOut(Execute := FALSE, Slave := o_PaperUnwinderAxis); o_SetPosition(Execute := FALSE, Axis := o_PaperUnwinderAxis); IF ... THEN i_StateMachine := 10; END_IF; 10: o_Power( Enable := TRUE, bRegulatorOn := TRUE, bDriveStart := TRUE, Axis := o_PaperUnwinderAxis ); IF o_Power.Status THEN i_StateMachine := 20; END_IF; 20: (* Avanzamento carta *) o_MoveAbs( Execute := TRUE, Position := o_Somewhere, Velocity := 25.0, Acceleration := 3666.7, Deceleration := 3666.7, Jerk := 48000.0, Direction := MC_DIRECTION.positive, Axis := o_PaperUnwinderAxis ); IF o_MoveAbs.Done THEN o_MoveAbs(Execute := FALSE, Axis := o_PaperUnwinderAxis); i_StateMachine := 30; END_IF 30: d_HomingPosition := ...; o_SetPosition( Execute := TRUE, Position := d_HomingPosition, Mode := FALSE, Axis := o_PaperUnwinderAxis ); (* ... *) IF o_SetPosition.Done = TRUE THEN o_SetPosition(Execute := FALSE, Axis := o_PaperUnwinderAxis ); o_LogServer.Append(sMessage := '...', lscClass := LOGSERVER_CLASS.ALWAYS, sdt := o_CommonsMgrData.systime.sdtLocal); i_StateMachine := 40; END_IF; 50: ... The code above is a sketchy example of what I wanted to write. But it gives me a spot problem: in some, the state change results in a drive error, which is unrecoverable except with a reinitialization via SM3_ReinitDrive(). Things are improved a little if in the program I always run the call of all softmotion blocks in this way: o_Power(Axis := o_PaperUnwinderAxis); o_Jog(Axis := o_PaperUnwinderAxis); o_Halt(Axis := o_PaperUnwinderAxis); o_MoveAbs(Axis := o_PaperUnwinderAxis); o_MoveRel(Axis := o_PaperUnwinderAxis); o_CamIn(Master := MachineEncoder, Slave := o_PaperUnwinderAxis); o_CamOut(Slave := o_PaperUnwinderAxis); If I don't execute all the calls of all the motion FBs used, when exchanging machine state often (but not always), the axis goes into error with event id THE_FB_WASNT_CALL... Done a little diagnostics it seems that the FBs return the bDone, before they are completely terminated. I tried doing the machine state exchange not with the bDone bit of the FBs, but with the 'standstill' state of the axis. It didn't seem to change anything. Problem 2: During the use SM3_ReinitDrive() I get the erro in the log: "NetID 0: SDO read error for object 16#607C..." Assuming that the device involved it's one of the two servodrive, (no others device are present in the network), I don't found any object 0x607C in the 'possible object list in/out' of the two drive, and I don't understand where this object can be listed. So any ideas and suggestions regarding these two issues will be very, very welcome. If you need the source project, I am willing to send it.

Post by kblundy on Change the Opening Position of the Dialog using VU.FbOpenDialog ^{CODESYS Forge talk (Post)}
I hope the community can help me with this. I need to use the Visu Utils FbOpenDialog to control the opening and closing of a dialog. I have the Opening and Closing working, but I can’t get the dialogue's position to be controlled. The code looks like this: PROGRAM OPEN_DIALOG VAR xOpenLatchSettingDialog : BOOL; TopLeftDialog : VisuStructPoint ; fbOpenLatchSettingsDialog : VU.FbOpenDialog ; END_VAR IF xOpenLatchSettingDialog THEN xOpenLatchSettingDialog:= FALSE ; TopLeftDialog.iX := 100; TopLeftDialog.iY := 23; fbOpenLatchSettingsDialog(sDialogName := 'visu_AlarmLatchSettings', xExecute := xOpenLatchSettingDialog , xModal := TRUE, itfClientFilter := VU.Globals.OnlyTargetVisu, pTopLeftPosition := ADR(TopLeftDialog)); CloseVisuDialog(sDialogName:= 'visu_AlarmLatchSettings'); ELSE xOpenLatchSettingDialog:= TRUE ; IF fbOpenLatchSettingsDialog.xError THEN xOpenLatchSettingDialog := FALSE; END_IF END_IF I can't seem to work out a way to make the values in TopLeftDialog.iX and TopleftDialog.iY be passed correctly in the call and for it to change the position of the dialogue box. The code is compiled, but the position has not been changed. Any guidance or suggestions for revising this code would be incredibly valuable. Your insights could be the key to solving this issue.

So the idee by 3s has a flod. Epis change the system to add the Stick. I send controller inc stick to Epis. On my software i can see the stick. An then you tel me i need a other license to use an license ?? Makes completly no sense. Codesys should be flexible but is not. I tried Delta. But has no HMI and has its own Codesys ?? Why ?? Then i tried Crist. The block there own system by a password. But dont know the password and cant switch it off. At the end the want me to pay for support to solve ther own made problem. So i send it al back. The extra license is adviced by 3s . Now a few month later still no working solution.

Post by yannickasselin on MQTT QoS 1 & 2 ^{CODESYS Forge talk (Post)}
Hello, I am using Codesys sp20p3 and IIoT library 1.11. I am trying to test QoS 1 & 2 and I have some issues. I am using mosquitto as the broker. I am also using some other MQTT clients like Node-Red and TwinCAT. They all work as expected for every QoS levels. I only have issues with Codesys MQTT client. In the Codesys client, if I subscribe to a topic as QoS 1 or 2, and a client publishes to this topic, I receive the message. But if I disconnect the Codesys client from the network and a client publishes to the subscribed topic, when I reconnect Codesys client to the network, I don't receive the messages as expected. Also there does not seem to be an auto-reconnect feature. So I have to manually set the mqttClient.xEnable bit to FALSE then back to TRUE in order to reconnect to the broker, then I also have to set the subscribe.xEnable to FALSE and back to TRUE in order to re-subscribe to the topic, but even then, I don't receive the messages that were published while I was disconnected. What am I doing wrong? I set the cleanSession bit to FALSE and I give my client a clientID. With the TwinCAT MQTT Client, I do the same thing and everything works as expected. It even auto-reconnects to the broker. I would expect Codesys MQTT Client to be as reliable as TwinCAT. Maybe I am doing something wrong? I also noticed that when trying to publish a QoS 1 or 2 message while disconnected from the broker, it does not work. In TwinCAT, I am still able to publish. The messages are stored in the client and published once reconnected to the broker. I would expect to be able to do the same thing in Codesys. Is this all possible? Am I doing something wrong? Thank you

If I do online monitoring of code in f.i. a function block, I cannot see if the function block is called or not. In software from other vendors you normally have an indication if the online code you are looking on is scanned at that moment or not. Is there a way in Codesys to determine in the online view if (parts) of the code are scanned or not? Thanks

All screenshots are enclosed in MS Word document. NOTE; 4 questions features at the end. Any assistance would be greatly appreciated! Hi everyone, I am still having device logon problem following a fresh install Here are the STEPS I went through following a FRESH CODESYS Win 64 3.5.19.60 install on a different computer. ‘Gateway not configured properly’ when attempting to REFRESH from the Users and Groups. Then did Gateway manage and confirmed it was ok: This message popped out as it was a fresh install: YES then: Initially went with Administrator twice (user & password) but it did not like it. No device is responding to …: Continued by setting a new user Pressed OK and obtained the following message: Stopped and Restarted PLC at that point: Obtained the following: Attempted to login a 2nd time without success. Then I scanned the network to see if matching device can be detected: Only way to get it detected was to remove the tick in the ‘Hide non-matching devices…’ Attempted a WINK but got a return like this one: REFRESH either @ Users and Groups or @ Access Rights returns: Then created user ‘mp’ at Project level ang logged in: Understandably device user mp9876 was not valid for the Project. Device information A few questions comes to my mind following these connection attempts: 1- Gateway not configured properly message pops out because of a non-compatible device ? 2- Why would the device not be compatible ? 3- Any way to make the device compatible ? 4- Any ideas on how to get this connectivity problem to the device solved ?

Hello TCIS_Send needs to be longer than 4 bytes because idata is 28 bytes long. There may be other ways, but I would make a UNION with string/array of bytes. Write your STRING into the AsString part then copy the AsBytes part into TCIS_Send (Elements [3] to [30]) then 252 would be in [31] (I've assumed the idata is always the same length)
