Post by winki on Modbus TCP & RTU with Control for Linux SL ^{CODESYS Forge talk (Post)}
For small project, I would like to use my industrial computer as a PLC + Industrial Computer. Like that I can save the cost of one PLC. That why I am using Codesys on Linux. With the nic it is not working. I already set the IP adress with /etc/network/interfaces. Can it comes from there ? looking to "Control Linux SL" docuemntation it should work with rtu.

Hello, Today I am able to test ma industrial computer in my test bench. I am able to do all the configuration throught my VPN, 100% remote. I can see the gateway & the Virtual PLC. Now I would like to do some Modbus TCP Client & Modbus RS485. But I am lost due to docker ! When I go to modbus TCP it only gave me the docker network, but not my eth0 & eth01 When I go to modbus rtu, how can I create the link between Com number & my /dev/ttyRS485 Loic,

Post by jeroenaero on CodeSys Raspberry pi I2C driver not found ^{CODESYS Forge talk (Post)}
I succeed to change the device to PI_SL but still the same problem of the I2C device switching between running and not running. the only difference with your project is that yo use I2C_master device version 4.7.0 and i 4.7.13, for GPIO i also use the 4.7.13 version and you the 4.7.0. Can you send me the older version of the Raspberry PI pheripals library, because i cannot choose lower version then 4.7.10 for the GPIO and I2C_master device

Finnaly i get it working. There was a line in the file that set the ADS1015 chip in /boot/firmware/config.txt which i removed and after that the ADS1115 has a green turning circle and i got values. i created a new component so it fits our ADS1015. see screenshot. It works also with Codesys Control for Raspberry Pi 64 SL after adding the ULINT_TO_UDINT conversion in the library. i think the chip was all the time in use by the Raspberry pi itself. Thanks for your help!

Post by s1ack on PFC200 Will soft-container & IIoT license survive a firmware update? ^{CODESYS Forge talk (Post)}
I have an IIoT License activated on a PFC200 with older firmware 2.08.32 (11). If I flash it to the latest available 4.05.10 (27) does the license get destroyed? I have a back up file '3SLicenseInfo.tar'. But this looks quite a bit different form the backup I got from more modern firmware... 'CMLicenseNew.WibuCmRaU'. Can the new license manager restore it from the old .tar?

Post by danwoodlock on RPI Zero w - Edge gateway cant install ^{CODESYS Forge talk (Post)}
Hello all, First post. I recently acquired an RPI zero W from amazon, and have been using it with Codesys v3.5 SP19 patch 2. I first got it working yesterday, and after installing the runtime on the Pi, I was prompted to install the edge gateway. Installation of the edge gateway failed because of unsupported architecture, undeterred I was able to connect to the pi and program as I wanted. The issue I've noticed is that if I do not load anything to the pi overnight, I can then no longer connect to the pi and download, although I can still ping it from my pc. I found that if I power cycle the PI, I am then able to connect again, and it works as normal. I did some googling and found instances where people recommended downloading the newest edge gateway, which brings me here. Wondering if there are any suggestions, or if this is a known issue. I actually tried installing all 3 versions of edge gateway for science, but all fail with the same message. Thanks -Dan

Post by arundara on Variable Sync Issue In Soft Plc Redundancy ^{CODESYS Forge talk (Post)}
Hello, I was trying to create a redundancy POC for our application where we read data from few modbus tcp devices. As there is a limitaion that modbus tcp device support only for single master device, we wanted to test how the variable sync happens in redundancy mode. For that i have used the redundancy sample code added a variable "b" under a condition. What i observed was while active controller is running, if passive controller is powerup, passive controller is able to sync all the data configured for redundacny. But after that the variable data which resided under a condition is not synching from active to passive controller. I have attached the image where i have highlighter the variable. Can some help me to understand how redundacny work in codesys soft plc and if there is a solution to sync variable which are under condition, please explain the same or suggestion to achieve the same. Hardware - Raspberry Pi (2 qty) Redundancy licence used - yes in both controllers. Codesys runtime - 4.9.0.0 Codesys software version - V3.5 SP19 if i have posted this question in wrong section, please do let me know in whcih section i have to post this question.

Post by tim-roelant on Problem mit control runtime V3 und profinet ^{CODESYS Forge talk (Post)}
Ich habe einen brandneuen Beckhoff-Panel-PC mit einer Codesys Control Runtime V3 eingerichtet. Ich habe es zusammen mit 2 Profinet-Feldgeräten konfiguriert: einem 16in/16out IO-Modul von Turck und einem MTS-Linearencoder. Die Maschine funktioniert einwandfrei, bis plötzlich die Kommunikation abbricht und die Profinet-Teilnehmer nicht mehr erreichbar sind. Zu diesem Zeitpunkt kann ich das Gerät noch anpingen, aber der Profinet-Master findet sie nicht mehr: Wenn ich einen Scan durchführe, werden sie nicht gefunden. Wenn ich einen Kaltstart durchführe, wird der Profinet-Master wieder aktiv und die Geräte werden wieder gefunden. Im Protokoll erhalte ich den Ethercat-Paketempfangsfehler: sysethernet. Ich bin etwas verwirrt, es gibt kein Ethercat-Gerät im Gerätebaum. Ich habe den Sendetakt und das Untersetzungsverhältnis bereits auf höhere Werte eingestellt, jedoch ohne Ergebnis. Kann Codesys so konfiguriert werden, dass die Kommunikation ohne Kalt-Reset wiederhergestellt wird? Das ist sehr ärgerlich und verursacht viele Produktionsausfälle. Grüße Tim

Post by thewizard8 on Raspberry PI4 Serial Port ^{CODESYS Forge talk (Post)}
Hi Dear All, I'm using my raspberry PI4 as a CoDeSyS PLC (Build from scratch with custom electronics). I was able to implement all fieldbuses with the exception of Modbus Serial. I'm using the internal Port (GPIO) and I configured it in /etc/Codesyscontrol_user.cfg the following away: [SysCom] Linux.Devicefile.1=/dev/ttyUSB0 Linux.Devicefile.2=/dev/ttyS0 I'm using COM2 on Master configuration. I'm using a interface board from TTL/RS485 (bidirectional board), and it's works perfectly with other devices but not in CoDeSyS. I'm able to send data with python script and read it on my pc using putty, but when I use a modbus slave simulator to interface with codesys I always get red icons on master and slave. (Please find image attached). I'm pretty shure that this might be a bad parameter on my CoDeSyS runtime configurstion file. Can someone help me? I'm stuck and this is for my master degree certification.

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 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.

As I wrote before on the title, I have difficulties to connect to see webvisu from localhost. The story: while waiting for the plc+hmi to arrive, I'm preparing the software, mainly the visual parts trough the control Win3 x64 (same version as the ide 3.5.20.10). The problem is that I can't see the webvisu with the installed webbrowser. I don't know if this is a problem, but I changed the port to 9001 (randomly "free") because 80, 8000, 8080, 8088, 3000 are all occupied by other projects (all on the Apache server). Is there something wrong with the config file? This is the url: localhost:9001/webvisu_app.htm and here the config file part "CmpWebServer". [CmpWebServer] ;The handling of startup/shutdown of the webserver: ;0->automatically start, shutdown only on shutdown of the runtime;1->automatically start, could be shutdown on demand ;2(default)->start/shutdown on demand;3->start on demand, shutdown only on shutdown of the runtime StartupType=0 ;The TCP port the webserver listens on WebServerPortNr=9001 LocalAddress=localhost ;LocalAdapterName=LAN-Connection LocalAdapterName=EthernetPCPLC ;LocalAdapterNameUnicode=L\00A\00N\00-\00C\00o\00n\00n\00e\00c\00t\00i\00o\00n\00 LocalAdapterNameUnicode=E\00t\00h\00e\00r\00n\00e\00t\00P\00C\00P\00L\00C\00 Thanks for all the help!

Post by shooxplc on How to call the same program from library and get the vars updated. ^{CODESYS Forge talk (Post)}
Hi, I am writing to you today because I would like to create a library that would contain a program with its various subprograms, in my example "PLC_PRG" with "a", "aa", "aaa". But once the library is created as shown below: I would like to be able to drag and drop my folder as many times as I want (let's say I manage the same system multiple times). Once the drag and drop is done, we can see the second folder with the variables renamed successfully. As shown below: But my variables in CAD_1 remain the same as for CAD, so it's PLC_PRG instead of PLC_PRG_1, for example. Is there a solution to automate this? I wouldn't want to have to rename all my variables manually, considering that in the program where I want to do this, the number of variables is substantial. Lucas.

Post by annd on Migration von "CODESYS Control for PFC200 SL" zu WAGO FW26 "CODESYS V3.5.19.2" ^{CODESYS Forge talk (Post)}
Hallo, da Wago nun von eCockpit zum offenen "CODESYS Development System V3" wechselt, möchte ich meinen bestehenden 750-8212 von der PFC200 SL auf die Wago Firmware umstellen. Welche Schritte sind dabei notwendig? Den Controller würde ich auf die aktuelle FW 26 updaten und die 3.5.19.2 von Wago mit den Descriptions verwenden. Reicht es im Codesys Projektbaum mit "Gerät aktualisieren" auf den Wago Controller zu wechseln? Es wird dann statt dem "Pfc200Bus"ein leerer K-Bus und ein leerer Com-Port angezeigt. Müssen die einzelnen Module dann darunter neu angelegt und alle E/A Variablen manuell neu eingetragen werden? Das exportieren und danach wieder importieren funktioniert nicht, weil die Namen bzw. Adressen unterschiedlich sind. Ist das so richtig? Kann der Block "Modbus_COM_Port - Modbus_Master_COM_Port - Modbus_Slave" so bleiben wie bisher oder muss das auch unter dem neuen COM-Port neu angelegt werden? Für ein paar Hinweise wäre ich dankbar. Schöne Grüße, annD

Post by ofey on Testing of Codesys program ^{CODESYS Forge talk (Post)}
Hi! I thought to hear what you guys think is the best way to test the program in my scenario. I have some PLC programs that have been made and deployed on different PLC's. The program has added the specific devices and IO that is applicable. I have made a test environment for everything outside of the PLC, ie. the same SCADA system that is talking to the PLC, and a program running locally is simulating the plant (level regulation of different tanks). Pr. now I have had to manually change the variables that are reading/writing values from the IO so they read/write via OPC instead. I also have to change the device tree from the specific PLC rack, to the soft PLC. So I kind of end up with two different programs that I have to maintain. I was just wondering if you believe there is an easier way to do this. So I can have the exactly same program and kind of switch between the soft mode, and the "real" mode.

Post by axilleas on SMC_Interpolator + SMC_controAxislbyPos ^{CODESYS Forge talk (Post)}
dear all I am working on a very generic gantry system (virtual drives + win v3 control) reading gcode from external file. In order to stop the interpolator function from running when gaps are detected, SMC_controlAxisByPos FB has the bStopIpo output which according to the manual is connected to the Interpolator's bEmergencyStop. Lets assume that the axis are parked in position X1000 Y1000 and the initial G code movement is G00 X500 Y500. The normal behavior is to travel from the actual x1000 y1000 to G00 X500 Y500. The SMC_Interpolator always gets the X0 Y0 as the initial position, meaning that the bStopIpo is active until the axis are in X0 Y0 and the release the interpolator to set the new positions to X500 Y500. Is there a suggested method to solve this behavior? bonus question: I get a lot of bStopIpo during standard interpolation movements (not gaps). While working with virtual axis this is not a problem but when real axis are installed this will be an issue. What exactly triggers the bStopIpo output? Slow axis accelerations compare to Gcode defaults? Kind Regards

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 manuknecht on High Cycle Times for SoftMotion_PlanningTask when using AxisGroup ^{CODESYS Forge talk (Post)}
Hello all I am using an AxisGroup with the Gantry2 Kinematics to move a 2D-Gantry system. When creating the AxisGroup, the SoftMotion_PlanningTask is created automatically with a cycle time of 2 ms in my case. I realized that the maximum cycle time of this task can spike to very high values (up to 60 ms) at lower speeds of the motion, leading to synchronization issues and errors on the axes. The same behaviour - though not as drastic - can be observed with virtual axes too. Is this behaviour intended or to be expected? Can the cycle time or type of the SoftMotion_PlanningTask be changed to prevent these errors? Or is there another fix for this issue? I tried changing the cycle type to Freewheeling, which solved the synchronization issues, but caused an error on the AxisGroup after a while, reading SMC_CP_QUEUE_UNDERRUN. Thanks in advance and best regards Manuel

Post by danieldiaz on Problem with FB execution ^{CODESYS Forge talk (Post)}
Hello everyone, I've been working on a system which needs an error function, with this purpose I've created a FB programmed in LD, after debugging I run the simulation. It seems that the variable linked to a coil doesn't change the value when the contacts are associated to input variables. When I use internal variables the logic works properly. I don't know if the problem is related to the variables definition or with the logic program. As you can see in the image, I1 and I2 are variables declared on the FB, the rest are input variables. If I force the eStop and Reset signals to TRUE the coil value should change, but it doesn't. However in the second network if I1 is TRUE the coil change to TRUE as it has to be. To sum up, my doubt is why that coil doesn't change its value? I would like someone to shed a light on this. Thanks!

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
