Post by vassilis91 on EtherCat-Rexroth Drive lost connection or no? ^{CODESYS Forge talk (Post)}
Hi all, i am encounter a mystery problem with a build with rexroth drives at my work. At my company we are make a machine with two Rexroth Indradrives . The two drives are goes by ethercat protocol . To be more specific i am going from my plc to the Beckoff El1100 coupler and after to the first drive and from the first drive to the second. The second drive works with no problem but the first(motor) sometimes without any pattern start to make a mysterious noise like stop and suddenly goes on again. If i couldn't hear the noise from the motor i couldn't Imagine that this happen. After a lot of research i see that sometime i have some strange zeros from the drive to the plc? Really i am in a deadlock and I don't know how to continue. From the other side the values on the other drive(second)are stable . The problem maybe: https://youtube.com/shorts/g7PCFLUaDUI?si=eiq0F2IzhQZax2e2

Post by oi18ct on ARM SL Development Board Recommendation ^{CODESYS Forge talk (Post)}
Hello codesys forum, My company is looking at developing a solution with Codesys ARM SL. The requirements will not tax the capabilities of Codesys. I would like to buy an AMR 7 or 8 Dev Board for experimenting. I am looking for a recommendation as I have minimal experience with Linux. Any input from the forum would be most appreciated as the hardware requirements as provided by Codesys for ARM SL seem pretty minimal (basically a arm7 or 8 with Debian is all). Our needs are small in scale- something like 8 digital inputs, 6 digital outputs, 2 analog inputs and 1 analog output. A small gui will be published via web visualization for external display (no local display). Communications with ModbusTCP and uart/RS485. It may be necessary to access i2c and make c or python calls to some existing code that is pretty small. Something like the EMCraft STM32MP1 SOM Starter Kit or Octavo Systems OSD32MP1-RED development board? Ideally something that has a path to a SoM for production. Kontron appears to have some interesting options too. Just having a hard time deciding where to start. Thanks in advance... LC

Post by nizrahel on OpC UA server on Raspberry Pi 64 SL runtime ^{CODESYS Forge talk (Post)}
Hi all! I'm working on an home project using a Raspberry Pi 3 device with Codesys for Raspberry Pi 64 SL runtime. I would like to create the HMI interface with Siemens WinCC Unified (or Advanced) configuring the Raspberry as OPC UA server. I tryed everything, but I didn't find the way to let the OPC UA connection works using UaExpert. I tryed to use anonymous connection, authenticated connection and the ip address instead of the server name in the path connection. There is no way to connect to the OPC UA server and I was asking myself if this feature is really supported for the runtime version used. Another strange thing I noted, is that is not possible to quickly create an OPC UA certificate in the Security Screen, as show in any tutorials. I have correctly created the Symbol Configuration enabling the OPC UA feature. I attach to this topic some printscreen of the actual configuration (sorry for the italian language interface, but I didn't find the way to switch to english). Thank you very much in advance for your support and advices!

Post by giackanto on Eoe issues with Windows and Linux ^{CODESYS Forge talk (Post)}
Hello, I've been trying to use EoE for communication between a Windows PC and an M753 drive from Control Technique. Despite following some online guides (https://content.helpme-codesys.com/en/libs/EtherCATStack/4.3.0.0/Ethernet_over_EtherCAT/fld-Ethernet_over_EtherCAT.html) I haven’t had any success. Both are connected to a Debian device where RTE is running: The PC is connected via the Ethernet port. The drive is connected via the EtherCAT port. I'm unable to ping the drive from my Windows PC. Here is my configuration: On Debian: (See attachments 1, 2, 3) enp1s0 = Ethernet port enp2s0 = EtherCAT port tap2 = TAP device IP forwarding and routes are both configured. On Windows: (See attachments 4, 5) On Codesys: (See attachments 6, 7) Version: Windows 11 Debian GNU/Linux 11 Codesys 3.5.17 Control for Linux SL 4.7.0 EtherCAT 4.4.0 With this configuration, I can ping the TAP device, but not the drive (See attachment 8). Could someone explain how to properly configure all these settings? Thank you, GA

Post by dhumphries on Minimum system requirements for codesys control standard S ^{CODESYS Forge talk (Post)}
I'm working on a low cost project and I'm considering installing the Codesys runtime on a PC running Linux Debian instead of buying a PLC with a pre-installed runtime. For my needs the Control Standard S license should be capable of running some IO over ethernet/ip, and a webvisu. The PC I am considering has a AMD GX-424CC 2.4GHz processor (4 core/4 thread) and 4GB RAM. This may compare to a raspberry pi4, but I know an X86 processor doesn't directly compare to an ARM processor, and a processor can have a high clock speed but other factors like L2/L3 cache can influence the overall performance. I can't find any published specs for the processor and RAM requirements to run the Codesys Control runtime, does anybody have a link to the minimum system requirements or experience using devices that are at or below the minimum system requirements. A raspberry pi with the control for raspberry pi SL runtime license would be the lowest cost option, but the license is not for commerical use. This restriction is somewhat vague, can anybody clarify if this means I can use a raspberry Pi runtime for in-house automation, what about if I am selling an integrated system that uses a raspberry Pi as a controller?

Post by forest on SM Drive license error ^{CODESYS Forge talk (Post)}
Hi, when it comes about license, I used INVTmatic Studio, which uses Codesys, for programming INVT plc. I bought Codesys Modbus license, it was not expensive, and then realised that INVT didn't have License Manager option (greyed out in program) which is needed for using of Codesys License. I contacted support from INVT, but developers told me that option is still not available. So depending on environment for programming Codesys, you can or not use Modbus license. Good thing about this version of Modbus TCP it works both direction. I could send commands and receive feedbacks from drive. But communication stops after 30 mins. So I used simple version of ethernet modbus which is somewhere in INVT or Condesys library (I can check tomorrow) which works only one way. I could send cmd to drive, and control it, but didn't have any feedback, like some readings back in PLC. which is bad, but at least I could start it and it didn't fail after 30 mins.

Post by levih on DocScripting ^{CODESYS Forge talk (Post)}
Hello I'm trying to use the DocScripting collection in Codesys. I've made it work on one PC(1) for the 3.5.16.4 version of the script collection. But when I try the same setup on another PC(2), I get an error message: Error loading Python DLL: D:\SCRIPTING\3.5.16.40\python27.dll (error code 14001) My setup on both PC's is thus: 1. Downloaded and installed Python 2. Copied the folder with the scripting collection to C: (because of admin rights) 3. Placed my .library file in the same folder as the scripting collection Only difference is that Python is v3.12.0 on PC1 and v3.12.1 on PC2. I thought maybe it was something with Python, but then I have tried using the scripting collection from 3.5.16.1, and that seems to work. Just not for scripting collection 3.5.16.4. I also can't seem to find any scripting collections on newer versions of Codesys? (e.g. 3.5.19.10) Thanks in advance!

Post by alex00 on DCS / Central Engineering with Codesys support ^{CODESYS Forge talk (Post)}
Hello together I'm currently investing in possibilities to have a central engineering software / system for Codesys based controllers. Something like a DCS / SCADA depending on where you see the functionality. We plan to use more or less vanilla codesys. The tool should support the following: - Connect to multiple PLC's in a project to see its variables and debug it. - Central Engineering capabilities (for example shared libraries in a project). - Download the new code / binaries to the plc. - Maybe have functionality to combine visualization elements and logic together. - See the live status variables on all the systems (crosscommunication). I see that codesys theoretically supports engineering of multiple PLC's, but I couldnt find to much functionality for a DCS type of operation, but that could be lack of knowledge. Any tips from you? Is Codesys good enough for this and maybe there are some manufacturers which build around it? Or are there good tools on the market with Codesys support (and the engineering is separate, but download to codesys possible). The use case is distributed energy installations like Heating pumps, Photovoltaics, etc. All these installations should have a PLC with codesys installed and run in one larger network, the PLC's are connected via VPN. Thanks for your inputs Greetings

Post by brell on Automatic xExecute NBS.TCP_write ^{CODESYS Forge talk (Post)}
I've recently started experimenting with CODESYS for a project and am fairly new to it. I'm currently working with Function Block Diagrams (FBD) to set up TCP communication between a server and a client, where the client is implemented as a Python script. Once the communication is established, my connection status changes to True, which is the expected behavior. My challenge arises with the TCP write module, which requires the xEnable_write flag to toggle between True and False. If xEnable_write remains True, the module only performs a single write operation. To address this, I introduced a falling edge trigger (F_TRIG), expecting it to help in toggling xEnable_write and it does, However, I've encountered an issue where in the beginning after connxion established I need to manually set xEnable_write to True for the system to work as intended. I'm looking for a way to automate this process so that xEnable_write becomes True automatically upon establishing a connection . Initially, I tried setting xEnable_write to True from the start, but this approach didn't work well since it left the flag permanently True, preventing further toggling. I also experimented with using a TON timer, but I faced similar issues. I am seeking a solution that automatically toggles xEnable_write between True and False after a connection is established, ensuring continuous write operations without manual intervention. Any advice or guidance on how to achieve this would be greatly appreciated."

Post by mtho on JSON Utilities - JSON file written with invalid structure ^{CODESYS Forge talk (Post)}
I'm using the JSON Utilities SL library to write configurations in my program to a file. I'm generating the JSON data using the builder function block and all appears to work correctly. When I write the jsondata to file, I'm finding that some of the JSON elements are not being written in the right location in the file. Rather than writing they keys under the parent object, they get written outside the root JSON object at the end of the file. If I then try to read the file back into the program, I get an invalid_structure error. I don't get any errors when populating the JSON data or when writing the file. I attached an example of the JSON writer output. The problems begin with key P200. Each P200 should go under MBR1 through MBR3. Among the rest of the keys, they are supposed to be under different parent objects. I am using default values for wsLineBreak and encoding.

Post by squiggleypuff on RemoteTargetVisu creates Unresolved Reference ^{CODESYS Forge talk (Post)}
I have a project with a Festo CPX-E-CEC-C1-PN PLC (Run-time version 3.5.12.50) that I have been developing on just fine using Codesys V3.5 SP19 Patch 5 (64bit). I am at the stage where I wanted to use the Festo HMI screen, and have added a RemoteTargetVisu object to my application. After adding this object, I am no longer able to log in to the PLC as I get an Unresolved Reference warning for 'USERMGRUSERGETPROPERTY' towards the end of the download process. I was able to find this post (https://forge.codesys.com/forge/talk/Visualization/thread/fc686a6cb2/) where the two possible solutions are to "set the placeholder to emtpy" or update the runtime. Problem is, I don't know how to do either of these things, as I'm still very green in Codesys land. I'd be happy to update the Festo PLC runtime, as that seems like the better option, but have not had any luck in finding a tutorial for this online. If anyone could point me in the right direction I'd appreciate it.

Post by alexgooi on Modbus writing on value change ^{CODESYS Forge talk (Post)}
Hi Duvan, You could make this in 1 single object (FB), Indeed don't use a function for this beacuse you need some memory to keep the old value. For i := 0 TO 200 BY 1 DO //Check if the value has been changed IF Old_Value[i] <> Value[i] THEN //Set the trigger to TRUE Trigger[i] := TRUE; Old_Value[i] := Value[i]; END_IF END_FOR If you define the Value array as an In_Out and the Trigger as an In_Out you arn't claiming any aditional memory to your system. You ofcourse then need to add some code arround it that does something with the trigger and writes it back to FALSE again. If you want more flexability you also could use pointers instead of using the IN_OUT FOR i := 0 TO 200 BY 1 DO address := address_Input + i * SIZEOF(*Put type here); IF Address^ <> Old_Value[i] THEN Trigger[i] := TRUE; Old_Value[i] := Address^; END_IF END_FOR

Post by duvanmoreno24 on Modbus writing on value change ^{CODESYS Forge talk (Post)}
Yes, I tried to do what you put in the first code. However, I have a problem with that and that is that the inputs must be declared with the type. I have many data types running in my code (real, int, uint, bool) and I can't put them in the same function, another thing is that I need to instantiate that function for everything I want to write to the slave. You put a for to 200 but it means that it has to be the same data type and inside the array, but I want to get them individually. I'm struggling to do it in a good and efficient way like wago's E-cockpit does. in the first screenshot you can see, you simply type in value, change the package of things you want to write in value change and it does everything by itself automatically, without comparing any old and new values and even less having the need to activate a bool. , it is perfect.

Post by squiggleypuff on Can't Add New Version of Modbus TCP Master ^{CODESYS Forge talk (Post)}
I'm having a tough time trying to get Modbus working on a Festo CPX-E PLC; it throws these pre-compiler errors as soon as I add in my Modbus TCP Master 3.5.12.30 to my project: I'm confused about the C0046 error, as I have IODrvModbusTCP 4.3.0.0 Library installed. So I thought maybe I needed to use the newest Modbus TCP Master 4.3.0.0, which is in my device repository: However, whenever I go to add this underneath the Ethernet adapter (which is version 4.2.0.0), the only TCP Master version available is the old 3.5.12.30 one, even if I have Display all versions checked.: I even went so far as to delete the old version, but then there were no options to add a Modbus TCP Master under my Ethernet adapter. What needs to be done to use the newest Modbus TCP Master? Or are these pre-compiler errors unrelated and I'm missing something? Any help greatly appreciated.

Post by fontrap on cmDongle Raspberry Pi issue ^{CODESYS Forge talk (Post)}
Hello mates, I'm working with CODESYS V3.5 SP20 on a Raspberry Pi and I use "Raspberry Pi MC SL" as device on the project. I've installed the Control Standard L (multicore) license on a Wibu System usb-Dongle (cmStick/4.50) that already had another license from another vendor. I follow the online activation procedure from CODESYS documentation. Raspberry Pi has already CodeMeter installed for the other license. When I plugin the dongle on Raspberry and start the Runtime from Raspberry Pi Update in CODESYS I receive the message that I'm on Demo mode because the license is missing. I double checked that the license is activated in the dongle, through the WebAdmin of CodeMeter and the second license runs properly without any issue. I have already try to change the dongle from HID to MSD device and backward but the the Runtime cannot recognize the Dongle. I have also try to stop and start the Runtime through CODESYS without success. Is there anything else I can do to fix this issue?

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?

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.
