      I am rather new to Codesys and I'm trying to figure out how to get the status of an alarm. This to interlock the start of a device until the alarm has been acknowledged... I am not sure if IAlarm.GetState (METH) can be used for this purpose. If yes then could someone please briefly explain how to use this? https://content.helpme-codesys.com/en/libs/AlarmManager/4.1.0.0/Interfaces/pou-IAlarm/GetState.html Thx & grtz, Kris

      Hi, Let's assume following: PRG_1 fb_1 : fbExample1; fb_1.method_1 do something... PRG_2 fb_2 : fbExample2; fb_2.method_2 if xTest then PRG_1.fb_1.method_1(); end_if; Is there a reason why runtime hangs when I call the method_1 in PRG_1 from a method in PRG_2? Both programs run in the same task. No chance that any other program calls the method. What I practically do there is that in the program PRG_2 I add a structed object into a buffer. In PRG_1 I just process the items in the buffer.

      Good morning, I'm trying to open a project but codesys tells me that there are certain packages that I don't have and that I need to download them. Once the installation of the packages begins, it shows me a error that the signature of certain packages does not correspond to that coming from the accepted installation context. Do you have a solution to my problem please, it is very urgent in my work. Sincerely

      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.

      What worked for me: Use SMC_SetControllerMode and set the nControllerMode to SMC_nocontrol. With that, you can control the drive via Modes of Operation(16#6060) and Controlword(16#6040) directly. Hope that helps, Cheers!

      Have you looked at this? https://forge.codesys.com/prj/codesys-example/element-collect/home/Home/ It's not exactly what you're looking for, but I've been able to make some things work more efficiently using this library.

      Select in tree "DEVICE", right-click and select "Update Device" Select "Library manager" and Change the version of the Library (down manualy). Samoetimes "Try reload Library". If you open a project version 3.5.19 in version 3.5.16, there are difficulties.

      Hi, I am looking for a way to define a local variable that will be multi user independent. This is so several user can connect at the same time select frames independent of each other.

      Thanks So Much for the reply! Were using the Weidmuller UV66-ADV-10-CAP-W The HMI is pointed to the URL which is assigned through u-OS. Basically when you log into the controller's webserver via browser you can view the installed apps. One of which is the Codesys runtime. When you click on that it takes you to the visualization. That corresponding url is what the HMI is looking for. I apologize I don't have that on hand as I'm in the office right now. I don't think I tried connecting using the port you mentioned and https in lieu of the u_OS URL. I can certainly try. Out of the box the u-OS is set for HTTP. Since we're isolated I havent changed that yet. When this has happened while logged on via chrome on my laptop, simply refreshing brings the visualization right back. In the case of the HMI in kiosk mode, we power cycle the HMI to force a reconnect, log back in u-OS and the visualization is back.

      Hi, I have a similar issue - we have been using codesys V3.5.16.20 Do you have any suggestions or confirmation that this will work with a different version of codesys and Pi extension

      I believe the reason that I eventually lose my ability connect is because of exceeding the time limit for demo mode. Still unsure why I cannot update the edge gateway though.

      Thanks very much for the explanation. I am basically new to the rpi world, but somewhat familiar with the indraworks/CtrlX versions of codesys. Appreciate your help.

      In the example project, you can see that a CAN.CANAreaReceiver is used which has an VAR_IN_OUT reference to a RECEIVER_AREA structure. This structure has a dwIdStart and dwIdEnd to filter a range of ID's and process them through the referenced msgProcessor.

      You could work around this problem by implementing some sort of "state machine". Each dialog sets a boolean variable when they are closed so you know which dialog was closed. Then you can react to this accordingly.

      I solved it by creating a new element of IElement according to the ElementExample (MyElement) in the ElementCollectionsExamples project. The variables in this element can then be defined in any properties as needed.

To search for an exact phrase, put it in quotes.  Example: "getting started docs"
To exclude a word or phrase, put a dash in front of it.  Example: docs -help
To search on specific fields, use these field names instead of a general text search.  You can group with AND or OR.
