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?

Post by fajean on CODESYS control on RPi starts, shortly runs, then exits ^{CODESYS Forge talk (Post)}
I have a Raspberry Pi 4 we have been using for years to run CODESYS for development purposes. I recently have had to re-install the OS (Raspberry OS lite). The only change to the default configuration is not creating the "pi" user during install. I (apparently successfully) installed the 4.10.0.0 control on the Raspberry Pi. We have licences on a dongle. I am able to start the control. systemctl status shows it as running for a little while (exactly, precisely 30 seconds as per my tests, every time), then it becomes exited. I can restart the control, and the same thing happens again. Every time. In the brief moments it is running, I can log in to the PLC. Working fast and restarting the control many times, I have been able to configure users. I have been able to download my application. I have been able to run the application, and stop on a breakpoint. I have been able to connect with the licence manager and confirm the dongle is detected and licences are listed as OK. I see nothing wrong until the service just exits. I have found nothing in the logs. It is like the runtime just terminates with no error code or message after exactly 30 seconds. Any help would be appreciated.

Post by kleeswi on Visualization scaling problem with B&R T30 panel ^{CODESYS Forge talk (Post)}
The probelm arises for the B&R T30 panel after updating Codesys from 3.5.17 to 3.5.19 patch 5. We have to use 3.5.19 for other reasons so we cannot downgrade the version. The scaling problem only exists for the B&R 6PPT30.0702.20F025 panel, the B&R T50 panel and a esa lumia panel work. When we choose a fixed resolution it looks also good, however we also want to support the esa lumia panel with a different resolution. The images show the anisotropic and isotropic option. In the anisotropic option it scales the hight correctly but not the width and in the isotropic option is scales both hight and width false, it also does not start in the top left corner. Does someone have any suggestion why it does not work anymore with the new codesys version and are there workarounds? I added all versions with visualization packages as an image, visuElems is 4.4.0.0.

Post by paulorb on STRUCT AT %MW1000 ^{CODESYS Forge talk (Post)}
Hi I am trying to use STRUCT to parse commands from Modbus/TCP, Modbus client will fill the bytes related to a specific command (type, parameters), then PLC (Codesys) will access the command parameters. A STRUCT will simplify a lot the process of parsing the data, so I don't need to parse byte per byte, address will be mapped to a struct and I can use it for parsing the data. From what I understood, the compiler does not allow me to specify the location of the struct for a %MW register. VAR_COMMAND AT %MW1002: structGenericModbusCommand; This will throw: Bad declaration, use '%ML' for 'structGenericModbusCommand' variable But If I change it to %ML, when you go online you see that it is actually allocating the struct in another memory address. When we go online, on GVL we can see: VAR_COMMAND. structGenericModbusCommand %ML1002 commandType COMMANDTYPE %MB8016 ... %MB8020 I am not specifying a pointer or a reference it is a struct type, why is it mapping to a %MW location (random one). How can I control where it is mapping to? I need a consistent way to map STRUCT to specific modbus address. Is it possible? Thanks, Paulo Note I am using a Codesys OEM: Schneider Machine Expert Logic Builder (M241)

Post by karel-bas on Loosing connection to emulation running on Linux ^{CODESYS Forge talk (Post)}
Hello, I am trying to emulate my code but for some reason my Codesys IDE keeps loosing connection to the emulator. I am constantly pinging virtual machine on which its running and its running fine, but codesys refuses to reconect to it, and is not able to rediscover it. Codesys 3.5 SP20 Patch 1 I have linux installed like image in attachment.(using version 4.12) Linux VM is set up to use up to 4 cores and 8gb of ram, with nothing else runing on it. I dont have a license so I am aware that the emulation shouldnt run for more then 120 minutes I am able to, login, get sysinfo, reboot etc from codesys IDE for certain period of time (5minutes) then my connection gets lost, sometimes I can login again, but sometimes i have to reboot the VM. Any suggestions what might be the issue ?

Post by rossanoparis on Clarifications regarding the appropriate runtime system to use ^{CODESYS Forge talk (Post)}
Thank you @TimvH It is clear that licences are application based and now thanks to your reply I could understand the meaning of RT systems. The RT called "CODESYS Control for Linux ARM SL" can be deployed on a generic debian based ARM system. The RT called "CODESYS Control for Raspberry Pi MC SL" is more specific for Rasberry HW. Did I understand correctly? Regarding the RT called "CODESYS Virtual Control SL" despite its description it is not clear to me when to use it. It seems that a project created using such RT system can be deployed on any HW. It sound good obviously, as it means that it is possible to realize a completely abstract project from its hardware. The only limit could be represented by the need of using a specific HW or OS feature, in that case a more specific RT system should be chosen. Is my last consideration correct? Regards Rossano

Post by egau on Hard shutdown: no code on device after power on ^{CODESYS Forge talk (Post)}
This explanation aligns with the issues we’re experiencing with our machines. The scenario I described is happening with one of them (let’s call it Machine A). This machine is identical to another one (Machine B), except for some custom code that facilitates communication with an external Beckhoff PLC for MES integration in the production line. Machine B has been powered on and off daily for at least three months and has never had this problem. Given that, I highly doubt the MES custom code is the cause of the code corruption. This being said, your explanation does seem plausible. However, if faulty EtherCAT cables were the issue, why wouldn't the error occur during normal operation? Why would bad cables only cause problems during a hard shutdown? One last question: When you encountered this behavior, did you see a similar error in your logs? i.e, an "AccessViolation" exception in the EtherCAT Task?

Post by hyys12 on Help understanding analog in-/outputs ^{CODESYS Forge talk (Post)}
Hello. I am currently working on a WAGO PLC, where I am trying to wrap my head around how the analog inputs and outputs work in codesys. I have looked far and wide on the internet, for a general introduction to the whole concept, but I have not had any luck with finding anything that helped me understand it better. The whole goal is for me to be able to read an analog input from a temperature sensor, as well as using an analog output, to control a frequency inverter. I know these have nothing to do with each other, but that is all I have on hand right now. I am trying to program this using Ladder Diagram. The only thing is, that every video/guide I have seen/read using LD, just adds a whole lot of function blocks, to do all kinds of stuff they don't explain. My general question is, how would one go ahead and read the analog input, as well as transmit an analog output? Is there some kind of specific function block I would have to use for this, or some great video I can watch, to understand the inner workings. Is it somehow possible to see the values the PLC recieved/sends? Regards.

Post by mubeta on Profibus DP master with EL6731 and automatic restart of slaves ^{CODESYS Forge talk (Post)}
WHEREAS, I have already searched various posts and forums, where mostly there are few references and mostly geared toward integration in TwinCAT. I am looking for how to properly configure the EL6731 board as a DP master, (where I have its 3S license), with CoDeSys 3.5.19.x. I have three types of slaves, all integrated with their GSD descriptors. In the tab for the various slaves, I don't see options related to node restart on 'station return'. On the card manual, I read that for each slave I should be able to configure parameter 8000:2C: “8000:2C Restart behavior after DP fault Reserve, must be 0 BIT1 RW 0x00 (0dec)” However, in the project I see no way to configure this parameter, in any of the boards; and the arrays do not always have such an extensive size; most of the time they are only two or three words in size. The problem is that, after the hot reset of CoDeSys, the master restarts by starting all slave nodes, but if one or more get lost and go offline, there is then no automatic restart upon their return. I would need to figure out any solution, even via software, how to figure out that this one is back available and restart it.

Post by imdatatas on Auto Declare window disappears by itself in the Ladder editor ^{CODESYS Forge talk (Post)}
Hello Everyone, The "Auto Declare" window disappears by itself in the Ladder editor. For example, a new function block is wanted to be added to the Ladder editor. (For example; MC_Jog block and instance name will be fbMcJog). To do this, "Empty box with EN/ENO" is added to the ladder line from the Toolbox on the right and when you type MC_Jog in the empty box and press enter, normally the "Auto Declare" window appears and you are expected to be asked to write the instance name here. However, this "Auto Declare" window closes itself immediately, it does not wait for the user to enter a value or close the window. I often encounter this situation in many IDE versions. Does this seem like a bug? If anyone has encountered a similar problem while creating a new program name, function or function block instance name regarding the "Auto Declare" window and knows a solution, I would be glad if you could share it. Best wishes Imdat

Post by struccc on The future and proper use of CAA.BOLT, CAA.SEMA,.. ^{CODESYS Forge talk (Post)}
Dear All, Dear CODESYS, I'm curiously following CODESYS transitioning away from the CAA libraries, and I'm mostly in favor of these major changes. Naturally, I'd like to align my current (not end-user) developments accordingly. I'm tracking , reading release notes, ... And want to figure out the future :) Is it possible to hear / read more about the reasons, objectives and scope of these changes? One important element is CAA Types - CAA Types Extern. What is the plan with that? What's the future of CAA.SEMA, CAA.BOLT ? I have never used them (always relied on SysLib*), but they are tempting... Would be useful to have a platform independent "Macro" for this functionality... Is there something in existing or planned ? Are they suitable to be used in low level libraries... For Example IO-Drivers, Components, "to-become system libraries"? CAA.TaskLock, CAA.TaskUnlock ? Well, they don't claim platform independency, so I can't rely on those.... Any up-to-date advise, standard, pattern to follow in new libraries for task and resource locking? Practical set of conditional defines to be used? If this information is not publicly available, can you please send a private message about the proper way to achieve this? I have support agreement, just couldn't get trough with these questions... P.

ENG For some reason, I can't bind a variable to the data parameter. Also, why does only the sdo_read4 function work for me? I also can't write through sdo_write4. I can only view the received values via sdo_read4. Please help me with this task. Moreover, I tried to write the values through sdo write 4 and for a while the data stopped being written and I overwritten it manually and sdo read4 started working again and at the same time they do not want to work in the main task. RU Я не могу почему то привязать переменную к параметру data. Так же у меня почему работает только функция sdo_read4 так же не могу записать через sdo_write4. Могу только просматривать полученные значения через sdo_read4. Помогите пожалуйста с этой задачей. Причём я попытался записать значения через sdo write 4 и у меня на какое то время перестали записываться данные и перезаписал вручную и sdo read4 начал работать снова и одновременно они не хотят работать в main task.

Post by pernockham on Engineering IDE from linux? ^{CODESYS Forge talk (Post)}
I have done the switch (linux mint, virtual windows through QEMU/KVM) now and is generally pleased. Have had problems in two areas initially. To bridge IP to the Virtual unit (solved), I overthought things initially. Solution. Configure manually a bridge in the mint-"network connections". Use that bridge in the Qemu settings as "Bridge device", "Device name": "name of the configured bridge" Figure out where to store the projects. I started out have the data in linux world (sort of) and linking it the windows with "virtio-fs". That had some serious impact though on git-handling. It seems that virtio-fs interpreted any file-path as lowercase only even if there were uppercase, resulting in git not able to sync files between its repository and the source code (it created a new file-path for me with only lowercase). Then I switch to samba-share instead and this works much better, though (git-actions) is a part that still has low performance with lots of waiting for file-actions. What should be the best way of handling the source/git? Edit to answer myself: Save the project "locally" in windows, then a lot of slow performance is avoided. Then a git-remote sync for backup.

Post by mubeta on Strange problem with the ‘MC_SetPosition’ function ^{CODESYS Forge talk (Post)}
How are the servo drives controlled? EtherCAT, step/dir pulses, other? CANOpen, 1 Mb/s, bus load 35%, cycle time 2ms. Another thought is that - if it's step/dir pulse based control - the pulses from the PLC to the drive are getting missed/lost at high frequencies? If that's the case then there would be multiple troubleshooting steps/corrections that could be investigated. Here, it seems to me that we are getting completely off track with the observed problem. You could try to create a simplified program I had already written this elsewhere. The program before being brought into machines was exhaustively tested in SW emulation and the problem did not occur. However, in emulation I was interested in checking other aspects of the process, not this specific one which is for real a correction made necessary after the fact. The part of the program that does this correction with the function mentioned in the topic, came up from its origins, but I didn't know or didn't think it was really useful. A scruple that later turned out to be necessary. However, for now I do not think I will spend any more time on this verification, already lacking any to do my normal. I remain amazed, however, that a function intended to correct the axis position with the motor in motion and that it should not interfere with this, in fact instead changes behavior as the motor speed changes. Mah! When you manually control the motor directly from the servo drive software at the speeds you are calling for, does it move precisely to the target position? The drive and motor have been working fine for about 10 years. In replacing the machine control system, I opted for CoDeSys where before there was something else. But this is not the subject of the problem. What I need to resolve is the fact that a clutch specially placed at a certain point can slip and, therefore, I have the undeniable need to phase the 'prime mover' to the mechanical position of the machine, detected by a cam for each turn, in order to properly stop at its optimum point. Which for now I have ruled out doing. In fact, if I really have to say, since we have now gone brutally OT, I originally thought that this clutch should only come into action in cases of extreme necessity, as happens in most trials. But this one, the way it is made, slips more easily than I could estimate and the servo-controlled 'prime mover,' and the machine, get out of phase, maybe by a little, but frequently, and when the machine work at it's high speed, (in fact all of the time), I can't adjust properly the 'prime mover' position at fly.

Hi. As far as projects in "old version"s are concerned, these can be upgraded to newer versions at any time. To do this, the device must be updated accordingly and the copilers and library versions must be adapted. You can find instructions on how to proceed in the online help/FAQ: https://content.helpme-codesys.com/en/CODESYS%20Development%20System/_cds_changing_compiler_version.html https://content.helpme-codesys.com/en/CODESYS%20Development%20System/_cds_cmd_update_device.html See also 4.3.22.4 "How to open an Example Project" within the following pdf for more details on the single steps: https://forge.codesys.com/lib/counit/tickets/_discuss/thread/3e991befbc/ca97/attachment/Public%20FAQ-v13-20240610_075228.pdf Regaring your OPCUA connection state always showing just "DISABLED", without knowing both sides of the assembly in detail, one can only approach the problem theoretically. We can give a chekclist on how to proceed: Fist, please recheck the communication settings in the OPC UA connection function block to ensure that the server URL, endpoint URL, and other settings are correct and match the configuration of the OPC UA server. Verify that the OPC UA server is running and accessible. -You can try to connect to the OPC UA server using a separate client, such as UAExpert, to ensure that the issue is not related to the OPC UA server itself. Test the security settings in the OPC UA connection function block to ensure that the correct security policy and certificate are selected. If you are using a dynamic connection to the OPC UA server, probe that the connection settings are correctly configured and that the OPC UA client is able to establish a connection to the OPC UA server. Also, please loock into the log files for any errors related to the OPC UA connection function block, these should be listet there. The log files may also provide additional information about the issue and help you to further troubleshoot the problem. FYI - Please see https://content.helpme-codesys.com/en/CODESYS%20Communication/_cds_obj_data_source_communication_opc_ua_server.html: Her you can finde the Communication settings via OPC UA Server -> layout Browse Live Server: The client connects to the server and detects the existing variables and types. From Information Model The client reads the data structure (layout) of the OPC UA Server from the information model set here and as a result receives the information about available variables and types. A connection to the server is not required. The list contains the information models installed in the OPC UA Information Model Repository. "Read Connection" Settings from IEC Variable (option set): - The connection settings used by the device are not read here from the dialog, but at runtime from the IEC variable specified here. - For this possibility, please see the Using a Dynamic Connection to an OPC UA Server (https://content.helpme-codesys.com/en/CODESYS%20Communication/_comm_use_dynamic_opc_ua_server_comm_settings.html) The settings for the communication of a Client-data source to an OPC UA Server can also be dynamically configured from the IEC code and can also be changed at runtime. For such a purpose, a structure is available in the DatasourceOpcUAServer library (For a description of the OPC UA Server, there is one included in the standard installation of CODESYS, https://content.helpme-codesys.com/en/CODESYS%20Communication/_cds_encrypt_communication_data_sources_opc_ua_client.html)

Post by ryandmg on Web Client (HMI) Disconnects from Webvisu (Weidmuller u-OS) ^{CODESYS Forge talk (Post)}
Hey Everyone, I'm having a bit of a struggle finding settings that will reliably maintain a connection between the webvisu and a touchscreen client. Every so often the HMI disconnects and will perpetually display the red spinning arrow with the "Error Happened, Will resume automatically" text. Power cycling the HMI to force a reconnect will re-establish comms. It seems to happen during periods of inactivity if that's a clue. From what I've gathered so far this seems to have something to do with the webvisu update rate, buffer size as well as the visu task scan rate. We first tried the default settings as follows: Webvisu Update Rate: 200 ms Webvisu Buffer Size: 50,000 Visu Task Scan Rate: 100 ms Priority 31 Other Tasks for Reference: Main Task Scan Rate: 100 ms Priority 1 Alarm Manager Scan Rate: 50 ms Priority 31 Ethercat Task: 4 ms Priority 1 This would disconnect some what regularly. We then made the following changes to try and stabilize: Webvisu Update Rate: 150 ms Webvisu Buffer Size: 75,000 Visu Task Scan Rate: 75 ms Kept other tasks the same. This seems to disconnect even more frequently. Also for reference the network is very small and only consists of the PLC, a small switch and the HMI. We're also not controlling frames from outside the visu program itself. The frame changes are all done natively. Any suggestions to get this to stop disconnecting? Oh and whatever the issue is the log does not record it. Figured I would ask here before opening a ticket. Thanks in advance for your help!

Post by r-niedermayer on C0564 Warning Message ^{CODESYS Forge talk (Post)}
Please see or Online Help on how to initialize variable before using them: https://content.helpme-codesys.com/en/CODESYS%20Development%20System/_cds_pragma_attribute_global_init_slot.html Regarding the Attribute global_init_slot: You can use this pragma to influence the order in which signatures are processed during global initialization. It can only be applied to signatures. By default, the initialization sequence for variables from global variable lists is undefined! However, if, for example, variables from one list depend on variables from another list, it is necessary to initialize one before the other. (Aee OLH and Syntax) The placeholder <slot> must be replaced by an integer value that defines the position in the initialization sequence.</slot> The default value is 50000. A lower value causes an earlier initialization! If several signatures have the same value for the 'global_init_slot' attribute, the order of their initialization remains undefined! Cautious application should therefore be considered! Example: The project contains f.e. two global variable lists GVL_1 and GVL_2. The global variable "A" is part of the global variable list GVL_1: {attribute 'global_init_slot' := '300'} VAR_GLOBAL A : INT:=1000; END_VAR The initialization values of the variables "B" and "C" of GVL_2 are dependent on the variable "A". {attribute 'global_init_slot' := '350'} VAR_GLOBAL B : INT:=A+1; C : INT:=A-1; END_VAR So if you set the 'global_init_slot' attribute of the global variable list GVL_1 to 300, i.e. to the lowest initialization value in the example, then it is ensured that the expression "A+1" is well-defined at the time of initialization of "B".

Hi after some assistance with an error on a Groov PR2 PLC. We have a few different communications set up as shown below: One Modbus TCP Slave Connection - ( Sending / Receiving Data from a PC ) Two Modbus TCP Master Connection - ( Reading Data from a UPS Panel and Reading Data Gas Chromatograph) One Modbus RTU Slave Connection 485 - (Reading Data from a fire and gas panel) One Modbus RTU Master Connection 485 - (Sending Data to a Telemetry Unit) All Licenses have been installed as per OPTO22 suggestions of the order below: Modbus TCP Master Modbus TCP Slave Modbus RTU Master Modbus RTU Slave When I check on License manager the RTU Master license seems to disappear on installing the RTU. (What ever reason I’ve been told this is “normal”). If I use Device License Read It will successfully read all the licenses correctly. Now the issue is every 2 hours and between 4. For what ever reason the communications seems to end and lock up for about 20 seconds. During this time even if I was logged into the PLC it would kick me off and I’d have to re type the password to enter. Most of the devices can handle this however the RTU flags up a communications failure at the SCADA and is raising alarms every 2 hours and 4 mins. We’ve had multiple people go through the code to check for anything obvious. Does anyone have any ideas?

Post by jeffg on ERROR: GetNetLinkSockAndInfoByMac(): could not open netlink socket: Too many open files ^{CODESYS Forge talk (Post)}
I just installed codesys runtime on a raspberry pi Cortex-A72 (ARM v8) 64-bit SoC @ 1.5GHz (Compute Module 4) I am running on Codesys control for raspberry pi 64 SL ver 4.13.0 and I keep getting a crash after about five to ten minutes. This program was running fine on a 32bit system with runtime 4.8 previously but they upgraded the panel PC cause it got smashed. Looking at the logs I see this error "ERROR: GetNetLinkSockAndInfoByMac(): could not open netlink socket: Too many open files" at the time of crash. I do have a UDP socket open for a serial to ethernet adapter and im wondering if maybe its opening a bunch of sockets and while receiving messages, Im not sending anything to the device only receiving. Below is the code used for the UDP VAR // Scale Comm fbPeerServer : NBS.UDP_Peer; ipAddress : NBS.IPv4Address; fbReceive : NBS.UDP_Receive; xPeerActiv : BOOL := TRUE; abyReceive : ARRAY [0..255] OF BYTE; sLastValidReceive : STRING(255); udiIndex : UDINT; END_VAR IF xPeerActiv AND NOT fbPeerServer.xBusy THEN ipAddress.SetInitialValue(ipAddress := gvlSettings.sIPAddres); fbPeerServer(xEnable := TRUE, itfIPAddress := ipAddress, uiPort := gvlSettings.uiPort); END_IF fbPeerServer(); fbReceive(xEnable := fbPeerServer.xBusy, itfPeer := fbPeerServer, pData := ADR(abyReceive), udiSize := SIZEOF(abyReceive)); IF fbReceive.udiCount > 0 THEN IF fbReceive.udiCount < SIZEOF(sLastValidReceive) THEN SysMem.SysMemCpy(pDest := ADR(sLastValidReceive), pSrc := ADR(abyReceive), udiCount := fbReceive.udiCount); // Set End of String sLastValidReceive[fbReceive.udiCount] := 0; END_IF END_IF If anyone as seen this I could really use some help figuring it out.
