Post by codesysbeginner on Eaton XC303 - USB Mounting / Trend manager ^{CODESYS Forge talk (Post)}
Hi, For a project I am using the trendmanager functionality, I changed the placeholder filepath to which the SQL database is saved to: home/disk_usb, $trend$. Which only works as long as the usb was mounted to the PLC at boot. However, I'd like to be able to switch the USB's out if they break or for data analysis. However when a new (or the same) USB is plugged back in the shortcut doens't exist on the device anymore. Also in the device directory under root/mnt/ a new folder appears SDB1 in addition to SDA1 to which the Trendmanager was originally writing. The SDA1 folder is empty/unreachable while the new SDB1 folder has the contents of the USB drive. I tried disabling the trendmanger while unplugging the USB's however this doesn't work. My question, how do I make it so that when I plug a USB drive back in, it will be mounted to SDA1 instead of SDB1? Kind Regards

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 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 e13740e on Сalling the context menu from the keyboard ^{CODESYS Forge talk (Post)}
Hello. I have a question for you, perhaps you have an answer to it. Regarding calling the Context menu from the keyboard in Devices, specifically calling the context menu window from the keyboard via an assigned combination. Goal: to have the ability to navigationally add internal Objects (Methods, Properties) to Function Blocks from the keyboard without using the mouse. The Codesys environment interface does not allow Windows access to this via Shift+F10. Externally (outside the Codesys environment), the hotkey call for the context menu (Shift+F10) from the keyboard works in various environments, but at the same time, in Codesys it does not (it doesn't work). I have already tried various options on my own to achieve this (but unsuccessfully): Tools\Customize\Keyboard\Objects (the set combination does not give the desired result) Tools\Customize\Keyboard\Objects... (the set combination is extremely useful as it provides access to adding objects directly to Devices but does not provide the ability to add an internal object (Method/Property) to a Function Block). Thank you in advance for your help!!! P.S. I have already started trying to implement a script-based solution to call the context menu via AutoHotkey - by relocating the mouse cursor to the area of the navigational selection with a subsequent call of the context menu on it and relocating the mouse cursor back to its initial position. And in order not to "reinvent the wheel," I am writing this request to you!!!

Post by xcqt on Oop best practice ^{CODESYS Forge talk (Post)}
Hi all, I’m currently trying to improve my OOP structure in CODESYS and I’m looking for some input on how others approach this. I understand the basics like inheritance, interfaces, abstract FBs, methods, and properties, but I still struggle a bit with the overall architecture and what’s considered clean or scalable in bigger projects. As an example, I’m working on two different energy meter function blocks: FB_EnergyMeter_MQTT reads data from MQTT (strings) FB_EnergyMeter_Modbus reads data from Modbus (words) Both have their own Update() method and implement the same interface (something like IF_EnergyMeter). Later on, I’ll probably add more meter types, but they should all behave the same from the controller’s point of view. Now, there’s a FB_GridControl block that needs power data from these meters. I see two options here: Define the meter blocks inside FB_GridControl and call them directly (for example fbModbusMeter.UpdateModbus()). Keep the meter blocks outside and pass them into FB_GridControl as interface references, so the control block doesn’t know which specific type of meter it’s dealing with. Option 2 feels cleaner and more flexible to me, but I’m not entirely sure how to handle the data flow in that case. Should I pass the meter instance through an interface reference (REFERENCE TO IF_EnergyMeter)? Or is there a better way to link the external FBs to the control block? I’d like to hear how you structure this kind of setup or see an example from someone who has done something similar. EDIT: I think i need to do something like this fbModbusUpdateInput(wInput:= wWordValue); fbMqttUpdateInput(strInput:= strStringValue); IF bUseMqtt THEN Meter REF = fbMqttUpdateInput; ELSE Meter REF = fbModbusUpdateInput; END_IF fbControl.SetMeter(UsedMeter := Meter); Or am i thinking wrong? Thanks, Thomas

Post by timvh on CANbus issue ^{CODESYS Forge talk (Post)}
On a PC with the Control Win, this is probably related to the fact that the CAN drivers are not loaded. Go to the folder where your Control Win Configuration file is: - E.g. C:\ProgramData\CODESYS\CODESYSControlWinV3x64\E1FA7ABE - Open the CODESYSControl.cfg - Remove the semi-colon in front of the CAN driver you want to use (section ComponentManager). - Set the component ID to the next number in the list (e.g. Component.8) - Save this file and restart the Control Win.

CODESYS IDE is not a modern IDE. Its interface is ugly, its operation is not user-friendly, its functions are lacking, its feedback is slow, and its development is not good enough. In fact, CODESYS is a helpless choice under the current situation. But this situation will not last long. For example, SIMATIC AX is a strong competitor of CODESYS, which is more open and inclusive.

Post by dantheman on Connecting to SoftPLC Only Works By Turning Off Modbus Ethernet Port ^{CODESYS Forge talk (Post)}
I have an IPC with 2 ethernet ports and 1 Wi-Fi. I'm using ModbusTCP with the ethernet port named "enp2s0" connected to my remote I/O. This works fine when testing with Python and also works with CODESYS, but CODESYS is only able to scan for the Linux SoftPLC when I turn off the "enp2s0" interface. In other words, I can't get online with the IDE if I want my ModbusTCP comms to run with CODESYS. I'm using a Linux SoftPLC that has the following entry in CODESYSControl.cfg, hoping that this will allow me to connect with "enp1s0" or "wlp3s0", and leave "enp2s0" for field comms, but this seems to only make the source IP of the ModbusTCP comms to be bound to "enp2s0". That last point is the case only if I don't restart the service, but if I do restart the service after changing the config file, the source IP for the ModbusTCP comms then becomes the one for "enp1s0", which is very confusing to me: [SysSocket] Adapter.0.Name="enp2s0" Adapter.0.EnableSetIpAndMask=1 On the device list, I only have "enp2s0" given as the ethernet device that has the ModbusTCP master & slave beneath it, shown in Screenshot 1. On the IPC, I can ping the ModbusTCP client (remote I/O) from "enp2s0", and I've attached a Wireshark capture of running ModbusTCP from the CODESYS runtime as Screenshot 2, 3 & 4 (again, I can't get online when this is running, I have to turn off "enp2s0" to connect even when it's idle and I don't have an active TCP session with my Python tests). Like I explained above, the source IP is "enp1s0", even though the ethernet device on the project is "enp2s0". I was lucky to catch the red message that showed the source IP that makes sense to me (the one for "enp2s0"), but for some reason that connection was reset and I never saw that packet again. I've also tried this with Auto-reconnect both enabled & disabled, for the ModbusTCP Master device. I also have to turn off "enp1s0" and then turn it on, just so that I can have the ModbusTCP comms running from "enp2s0" (which is not intuitive in any way to me, I'd love some help understanding that phenomenon as well) in the weird manner that I've described above. I would be very appreciative if someone can help me figure out this pickle. I'd love to just connect to CODESYS through my Wi-Fi interface and leave my ethernet ports for field comms.

Post by duvanmoreno24 on Modbus writing on value change ^{CODESYS Forge talk (Post)}
Hi all, I want to know if someone has an idea of how I can write on value change in Modbus Codesys. I have a Wago PLC and I was used to work with E-cockpit which it was quite easy to do that without the necessity to trigger any value when there was a change in the variable ( I will put how easy is ). how you can see just changing the trigger in "On value Change" will do that channel writing automatically when It detects a change in those arrays. On the other hand, in Codesys if I enable the rising edge in Codesys It ask me to put a bool variable and if triggers is going to write that value. That is making me that I have to create a function or a logic to detect the change, the problem I have is that doing that is very tedious. I first approach I got it was to create a Function who returns a bool when the value change, but I tried to keep the old value but what is happening is that in Functions all the data is erased every cycle so I can not keep any Old value. so in the Main program the trigger is going to be TRUE all the time due, the old value is cero every cycle. The second approach I got it was using a function Block (POU_1) and it works but I dont want to instance that function for every Channel or value that I want to check if the value change, Basically if I have 200 values to write trhough modbus I have to create 200 instances of that function which I think it is not practicall at all. It should be a better way to implement this as e-Cockpit from Wago Does. However, I haven't been able to know how.

Post by manuknecht on Maximum dynamic limits of MC_MoveLinearAbsolute and MC_MoveLinearRelative ^{CODESYS Forge talk (Post)}
Hello all I use an axis group with two linear axes in a kinematic system. Using MC_MoveLinearAbsolute and MC_MoveLinearRelative, I am trying to realise dynamic movements (set velocity: 1 m/s, set acceleration: 30 m/s^2) with the highest possible jerk, as I want to compare this with a movement with a trapezoidal velocity profile. However, my measurements show that the axes accelerate with a maximum jerk of approx. 800 m/s^3, even if the value in the function block was set to 10,000 m/s^3. I have already increased the dynamic limits of the two axes accordingly (Velocity: 5000 u/s, Acc-/Deceleration: 250'000 u/s^2, Jerk: 100'000'000 u/s^3, where 1 u = 1 mm), but this had no effect. I have checked the input parameters of the function blocks and the VelFactor, AccFactor and JerkFactor factors are all set to the maximum (value 1). Reducing the cycle time has resulted in a higher jerk, but as we are already working with a cycle time of 1 ms, there is nothing more that can be done here. The axes themselves are still a long way from drawing the maximum current, which is why I assume that this should not be a problem either. Are there other factors or parameters that influence the dynamic limits and therefore allow faster movements? The PLC I am using is a Raspberry Pi 4 and Codesys V3.5 SP20 with all libraries up to date. Thanks in advance Manuel

Post by etienneneu on loading delay with the option "check client animations and overlay of native elements" ^{CODESYS Forge talk (Post)}
Hey NicolaG_89, thanks for the tip. But I have seen in the developer tools of the Webclient that a multiple fetching of the image and script data occurs when changing frames (HTTP code 304 NOT Modified), although these are already in the clients cache, which leads to unnecessary loading of resources from the web server. This behavior can also be found if the option “Support client animations and overlay of native elements” is deactivated, but this does not lead to such long delays. I had already tested loading all Visu elements so that everything was fetched once before they could be used. But that didn't help either. To prevent this behavior (permanent fetching), I have used a different way of switching the Visu elements in the VisuDemo Project, which also uses HTML5 control elements. I implemented this with the visibility of entire Visu elements. As a result, it only has to be fetched once and does not have to be fetched again when reloading. But I am still unsure about this implementation if the scope of the visualization becomes larger, as the Codesys visualization documentation advises against using many invisible elements. Best regards Etienne

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.

We filter buttons with input locks and visible items with [CURRENTCLIENTID] on different WebVisu's with different ID's, and one time the itfClient used the same Client ID for 2 Clients, so the Visualization on the first ID was wrong, because that one which connected after did not have the same permissions like the first, so the first one was blocked. We read the Clients with the VisuClientIteration project: //count active clients gCli.iNumberOfClients:=gCli.iNumberOfClients+1; // if client is active write data to global struct IF gCli.iNumberOfClients > 0 THEN gCli.astClientInfo[gCli.iNumberOfClients-1].iClientID:=itfClient.ClientId ; gCli.astClientInfo[gCli.iNumberOfClients-1].stCurrentVisu:=itfClient.CurrentVisuName; gCli.astClientInfo[gCli.iNumberOfClients-1].wsUserName:=itfClient.UserName; gCli.astClientInfo[gCli.iNumberOfClients-1].sIpAddress:=itfClient.GetIPv4Address(); gCli.astClientInfo[gCli.iNumberOfClients-1].ClientType:=itfClient.ClientType; END_IF Runtime from the device: 3.5.19.20 Codesys we use: 3.5.20.10 I added a screenshot where the same ID exists 2 times. Thanks for your answers.
