Post by phoward131 on Alarm State Icon ^{CODESYS Forge talk (Post)}
I am trying to create an icon on an overview screen that depicts if an alarm group has active alarms, active acknowledged alarms, or inactive unacknowledged alarms (waiting for confirmation). I've attempted to set up Notification Actions in the Alarm Class to set variables based on state changes but have been unable to find a clean and effective way to do this. Because an action on any alarm will trigger the variable to be set as instructed, I'm struggling to find a way to configure it for what I need (ie if two alarms activate, then one deactivates, the variable for indicating an alarm is active would be cleared after the single deactivation). I've been pointed toward the Alarm Manager example project but I'm finding it too complicated to understand how to implement it in my own project. Has anyone come up with another good way to indicate the states of alarms or a simpler usage of the Alarm Manager functions?

What we are trying to explain is that, yes CODESYS creates the software, but Epis decides how they implement it on their hardware, which runtime version they use and they decide which functionality they support. So it is always a combination of the two. What CODESYS provides is a runtime with options for e.g. visualization or softmotion. Epis could add this softmotion license as default to their controller, but if they don't then CODESYS provides another option with a single license in a "Wibu CodeMeter" container. Eventhough the feature exists, Epis has to add this "CodeMeter" software on their controller to be able to access the licenses in the container. We don't know if they did this. Then finally it depends on what type of runtime is on this controller and which license Epis is using. So if they have an OEM license (not an application based license), then most likely you will need the Softmotion license (not a number of axis). See https://store.codesys.com/en/codesys-softmotion-sl-bundle.html. But to be sure if this is supported by the Epis controller, you must ask Epis.

Post by biiebs on Aufbau von Ablaufsteuerungen ermitteln ^{CODESYS Forge talk (Post)}
Hallo Zusammen, gibt es in CODESYS bei Ablaufsteuerungen weitere Möglichkeiten außer den AS-Einstellungen z.B. die Aufbaustruktur der Ablaufsteuerung herauszufinden? Gesamtanzahl der verwendeten Aktionen / Schritte - Im besten Fall auch die einzelnen Verzweigungen? Ich würde den gesamten Aufbau der Schrittkette gerne als "View" in einer übergeordneten Software abbilden lassen, da sich die Ablaufsteuerungen, je nach Projekt im Aufbau unterscheiden bräuchte ich die Kenntniss über den Aufbau dieser Schrittketten. Oder müsste ich mir hier einen "Workaround" programmieren, der z.B. bei Init erstmal den Aufbau der Ablaufsteuerung durchläuft und mir die nötigen Informationen liefert? Natürlich wäre auch ein Weg den Aufbau des AS-Bausteins über die PLCopen XML zu exportieren, jedoch müsste dies bei Änderungen jeweils nachgezogen werden - was etwas unschön wäre, falls dies vergessen würde. Mittlerweile habe ich auch das Tool "SFC Visu Generator" gefunden, dessen Funktion im Prinzip genau das darstellt, was ich benötige - jedoch leider nur als CODESYS interne Visualisierung. Ich würde den Export des Bausteins gerne in meine übergeordnete Software implementieren. Gibt es hier die Möglichkeit das Vorgehen zu Erfahren oder den vom Baustein generierten Export bei mir zu implementieren? Hat hier jemand sowas ähnliches schonmal gelöst? Vielen Dank im Voraus Mit freundlichen Grüßen Biiebs

Post by gediminas on Datasource OPC UA client system failure ^{CODESYS Forge talk (Post)}
I am using CODESYS v3.5 SP20 Patch 3 / Control for BeagleboneBlack SL v4.13 and after some time the OPC UA Server crashes. However, Runtime still works without any issues. The events leading up to the OPC server crash are the most suspicious: 1) Mutex deadlock detected - owner thread died, and 2) Runtime received SIGABRT. And it seems very similar with this topic except used versions - issues should be fixed with previous SP's. I can't seem to find any information about these events. Need some pointers in the right direction on how I can fix this problem.

Post by climblinne on OPC UA Method - How to wait for result? ^{CODESYS Forge talk (Post)}
Hello, I am already able to run an OPC UA method in Codesys. Now my question, how can I interact with other tasks (e.g. read an SDO from EtherCAT and return it by the function)? The OPC UA method seems to be called only once (I tried to return BOOL or UINT values). Up to now I only found to do a while loop to wait for the result of the other task. Is there a better way to do it? Is this the way OPC UA functions should be used (for "not too long" function calls) or should I use another mechanism (method: Start, event: Finish, method: getResult)? Regards

Post by matthew on High resolution displays with 150% scaling causes CodeSys IDE to be blurry ^{CODESYS Forge talk (Post)}
I have just upgraded my laptop which has a high res display 2560x1600 and I have to have scaling switch on at 150% but everything looks blurry and not crisp, It seems CodeSys IDE is the only software on my system to look this bad, if I switch to 100% it's crisp but way to small. From a bit of research this could be due to the use of old windows forms or something? I have found a temp workaround that sort of works but not great. You have to run CodeSys in compatibility mode and adjust the DPI settings, this works ok and the editor is clear and crisp again but the actual tool bars are small like running at 100% Anyone got any tips for running CodeSys on high res displays with scaling?

Post by struccc on Problem Reading Registers via Modbus from non Codesys device ^{CODESYS Forge talk (Post)}
Hi, Might be a good idea first to try out the connection and the device with some handy software, like Modbus Poll. There you can see better, what's really going on... - Is it really connected? - What error code does it return? - Can it read from the register address? - Maybe try Input registers and Holding Registers - can make a difference - Sometimes register addresses are messed up: shifted +-1 (mixing of 2 standards) - Sometimes register addresses start with offset 30000, 40000 ... - Are you using the right protocol? - Is it RTU or TCP? Maybe ASCII? - Can even have a look at the data packets, etc... All this is easier to figure out first with some modbus utility... and then to set it up in CODESYS should not be an issue. P.

I'm programming an HMI for a machine. I want to log all the parameter's changes (used text field for displaying and changing) for particular User levels. Created a Numpad and want to log oldvalue and Newvalue on 'ok' Button press. To retrieve the oldvalue, i check if the dialogue opened is my Numpad, Then I retrieve the dialogue interface via GetDialogInterface(ADR(myNumpad)) --> numpadData.stVariableValue which contain my oldvalue and save it locally. Problem is sometimes i retrieve the data and sometimes not. Also observed when Numpad Dialogue is Opened, VisuDlgUtil_IsDialogOpen returns False in some cycles.Attached you will find my Project. please let me know what went wrong or if there is a better approach to collect old and New Value of a textfield.

Hi, i found a solution for me. I had installed a 'old' version of CoDeSys (3.5.18 P5). I tried to add channels there, which works fine. I created a new project, added an Ethernet-Port, added a Modbus-Master and then I copied the ModBus-Slave from my working project to the new project. Now I could add more channels. I add the channels 10 and 11. Then I deleted (please make a backup before :-) the original ModBus-Slave in my working project and copied the extended Slave back to my working project. Surprisingly it is now possible to add new channels. Maybe this will help you.

Post by jaspergain on Non-existing identifiers ^{CODESYS Forge talk (Post)}
Hello, I got a bit of a weird issue going on which is kind of annoying. So recently we switched a lot of Modbus IO to EtherCAT, as we were having issues with stability. All works fine, which is great. But sometimes when I change the program I get errors claiming that identifiers are not defined. Meaning I can't go online. See the picture below. I believe this is because some of these identifiers were used with Modbus, and they weren't properly removed/deleted? A clean all temporary fixes the issue, but it comes back again after a while of changing the code, and building. Any way to fix these non-existing required identifiers, or even find out where they are required? Thanks for the help in advance. Jasper.

Hello, CODESYS Control is running on my RevPi, and my system communicates over a CANbus with a master using the ConnectCan module (Slave - CANopen Device). The communication works perfectly fine so far. However, as soon as I call a Python script with "SysProcessExecuteCommand2" that creates a CSV file and executes without errors, the master does not adopt any changes to the Transmission Process Data Objects (TPDOs). I don't quite understand what one has to do with the other, and perhaps someone can help me with this.

Post by wbj0t on mobus tcp slave device. read/write holdings with 2 variables. ^{CODESYS Forge talk (Post)}
Hi there. I have an issue to read and set time for the controller. In the issue many registers described as writable by 6/16 functions, and, in this time, also(!) readable! For example: I have time registers: min, hour, day, mon, year. By specifications it is possible check time (so I need always update these varibles in loop) and set time by writing these same registers, BUT how to set, if they will immediatle updated by current time after writing? So, I need to separate one address at two variables. I have seen option mark: Overlay of the process image by the holding and input register. I understand this so: When I READ by function 3, I will get variable that connected with the same INPUT address and when I WRITE by 6/16 this will change second variable that connected with HOLDING address. BUT, this mark doesnt work, when I write 6/16 and try to get by function 3, I will get written value instead INPUT variable. So, what to do?

Post by shabroz-gill on Exception when OPCUA datasource disconnects from Server ^{CODESYS Forge talk (Post)}
If i loose the network and the opcua data source suddenly looses connection with the server, i get an exception and my application stops working. I am using the latest version of the communication add v4.5.2.0 Is this a known issue? This makes the datasource unusable because it is inevitable that we will loose connectivity at some point, and the datasource crashing everything due to that seems to be a deal breaker. I can provide more details is someone from codesys is reading this. You can recreate is by just shutting off the Opc server after the codesys data source is connected and reading data from it. The codesys app does not crash everytime and sometimes it is able to reconnect without crashing, so you may have to try this a few times to see the exception. Best regards

Post by ivanj on Codesys V3 + Rpi + PCA9685 + two robot arms ^{CODESYS Forge talk (Post)}
greetings to everyone I have a system consisting of rpi3 computer with codesys v3 installed connected to one pca9685 through which the servo motors of the two robotic arms are connected (each robot arm has 6 motors) I managed to get that the pca9685 can only drive 4 servos on the first arm the other 2 on the same robot arm do not respond, nor do the remaining 6 they do not react on the other robotic arm. Power is connected to the pca9685 for motors of sufficient power or amperage. I tried to put another pca9685 but the same thing happens again. What is the possible problem?

Post by trusty-squire on Read "Homed" status from EtherCAT drive ^{CODESYS Forge talk (Post)}
Hi, Is there a way to read the homed status from the EtherCAT drive directly? I am currently flagging the homed status on the succesful completion of the MC_Home function block, but I have had false triggers where the drive didn't actually execute the homing procedure but the MC_Home FB is marked as complete without error. I looked at other MC/SMC function blocks but the closest I can find is the "Homing" bit from MC_ReadStatus FB, but this doesn't show if the drive is succesfully homed, only that it's homing. Any guidance is welcome. Thanks!

Post by sawicpx on CANbus Remapping PDOs During Runtime ^{CODESYS Forge talk (Post)}
Hello, I am working on an application where I need to remap PDOs to a different CANopen object during runtime depending on what value is at a specific register. I have gotten to the point where I put the device into Preoperational State using the CIA405.NMT function. I then reconfigure the PDO 180x and 1a0x obejcts usings SDOs to point to a new canopen object on the device however when I go to restart the Device from PREOP to OP using the CIA405.NMT function the device is reset back to the original configuration as per the initial setup. I am wondering is there any way to change the PDOs at runtime is there some more functionaility I can access to do this. Any direction is appreciated!

Post by mp9876 on Device User Logon ^{CODESYS Forge talk (Post)}
Following up on the invalid user authentication on the target Not 100% sure what the problem was but following my post I managed to create an administrator level user. Then my next issue was that I could not connect to the device. I might have flipped the device from a 64 bit version to a 32 bit version so I did UPDATE DEVICE back to the 64 bit version; still could not connect somehow. Then I did two things at the same time that fixed my problem: Wiped the Codesys Control Win 64 bit version and installed the 32 bit version Installed latest Codesys Control Win V3.5 SP20 (released today) I wish I knew which one of these actions fixed the problem but at least the problem is solved. Hoping this post may help someone one day
