Post by cdutz on Problems connecting to Codesys 4.9.0.0 runtime on my Wago PFC200 ^{CODESYS Forge talk (Post)}
Turns out I managed to get a connection to my PLC. It seems that a few weeks ago Wago released something with version 4.3.3(25). So I reset my PLC to Factory-Reset, set it to the 192.168.1.17 IP and changed the IP to the one I wanted with the Wago EthernetSettings tool. Then updated the latest firmware using the WAGOupload tool. Now the PLC came back up without a PLC runtime running, so in the Web-tool I wen't to the "Configuration"/"PLC Runtime" and selected the runtime version "CODESYS V3". I uninstalled all Codesys versions and installed the version from the download package of Wago together with all the packages the bundle provided. After creating a new project I didn't select the old PFC200 runtime, but one of the dozens of new device profiles, that it now listed. With these settings I was then able to connect to my PLC. Now I hope I'll get the existing project that I had ported to this new structure. Sorry for the noise. Chris

Post by garyl on Comments in arrays and assigning RST coil's to 600 outputs ^{CODESYS Forge talk (Post)}
Hello all, im working on a project that requires me to convert an old automation direct DirectSoft PLC d2-250-1. One of the problems im encountering is that all of the comments are attached to members of the different addresses. When i convert the addresses (1777 "C" registers, 777 X registers, and 20,0000 V registers) im running into difficulties keeping the inputs/outputs correct since they are missing documentation. Is there a good way to retain the comments of the indexes in the array? Secondly, initially i was declaring the "C" and "V" addresses individually and this worked to retain the comments as to which register did what, however i ran into a problem when one rung reset (or set to 0) approximately 600 C Addresses. Since each tag is separately declared this proved to be nearly impossible without a literal wall of code that attempted to crash the program. So i converted all of the registers (C,X,Y,V) into separate structs, declared them as arrays and pointed all of the original call outs in the program to the newly defined structs. However i have now lost comments and the program is very hard to follow. Thanks for any help with this issue.

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 manuknecht on Persistence Manager does not save alphabetically first value ^{CODESYS Forge talk (Post)}
I have several libraries which contain values that should be saved on a PLC. As apparently no Persistent Variable List is available within Libraries, I use the Persistence Manager to create a Persistence Channel in the Project which imports the library. I then specify the persistence channel in the library using the {attribute 'ac_persist':='PersistenceChannel_CT'} specifier. This generally works very well and gives me exactly the properties I require. However, it came to my attention that the (alphabetially) first value from the library is not saved in the created ASCII file. When checking the content of the Persistence Channel, it shows all the variables as defined in the library. But the created file does not contain the first value and it is not restored after restart or reset. (see attached picture) I disabled Periodic Saving and set xSaveOnChange to TRUE and so the file usually updates immediately after changing one of the values. When changing the first value, it does not update which is consistent with this value not being saved. I also created a sample project and library from scratch which shows the same issue both using a Raspberry Pi and using a Linux machine. Does someone know what the reason for this could be or did someone make similar experiences? Looking forward to hearing your suggestions. Thanks in advance and best wishes Manuel

Post by moksan on Unconnected_Send Explicit message with Route Path ^{CODESYS Forge talk (Post)}
I have been trying out Unconnected_Send Explicit Message with route path.(The Unconnected_Send service shall use the Connection Manager object in each router to forward the message and to remember the return path. Vol 1.3 / 3-5.6.7) However, I could not see the correct path on Wireshark. I want to see the Unconnected_Send Message Service Code as 0x52 and also the last of the message should have the route path. I want to ask some questions about this topic. The IIoDrvEIPAcylicServices Interface has the IoDrvSendUnconnectedMessage Method. And there is a struct (EIP_SendUnconnectedMessage) for this service. But there is no information about how to implement to project, and if it is successful, does it send a message with 0x52 Unconnected_Send Service Code or not? If that is not a solution, how can I set the Unconnected_Send Explicit Message struct on Codesys? Also how can I send explicit message with route path?

Post by riccardo on VisuElems.CurrentUserGroupId is not stable ^{CODESYS Forge talk (Post)}
GoodMorning everyone. I have a system that, in case of alarm, have to block. When the operator logs in must have to acknoledge the alarm and should operate in the system freely. To perform this I detect the logged User by (VisuElems.CurrentUserGroupID <> 0) with a similar code to the the following: PROGRAM AlarmMngt VAR alarm : BOOL:= FALSE; Ack : BOOL:= TRUE; PushBottonOpening : BOOL:= FALSE; Valve : BOOL := FALSE; Flag: BOOL := FALSE; END_VAR IF alarm AND Ack AND (NOT Flag) THEN valve := FALSE; PushBottonOpening := FALSE; Ack := FALSE flag := TRUE; ELSIF (NOT alarm) AND Ack THEN flag := FALSE; END_IF (* if the system is in alarm but there is a logged operator that acknowledge the alarm the system allows the valve opening.*) IF (VisuElems.CurrentUserGroupID <> 0) AND Ack AND Alarm AND PushBottonOpening THEN Valve := TRUE; ELSIF (VisuElems.CurrentUserGroupID = 0) AND Alarm THEN valve := FALSE; END_IF The problem I have is in the last 5 lines of the code: Even if there is a logged in user, the GroupID variable is subjected to a refresh that cyclically set for an instant it to 0 and this close the valve making difficult to the user to work Now I solved it creating a time hysteresys cycle but it is not a good solution. Someone is able to explane me why the GroupID variable is sobjected to this refresh and how to stabilize to avoiding it? Thank you in advance, Riccardo

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

Ich hab's hinbekommen: Nach dem Controller Update hab ich ein neues Projekt gemacht und nur den PFC200(8212) eingefügt (es erscheint dann ein leerer Kbus und eine serielle Schnittstelle COM1). Dann hab ich mich am Controller eingeloggt und den Kbus (Rechtsklick: Geräte suchen) mit allen Modulen automatisch ergänzen lassen. Bei den leeren Modulen hab ich dann das E/A-Abbild in csv exportiert. Dasselbe hab ich bei meinem alten "PFC200 SL" Projekt gemacht. Und dann in Excel alle Variablennamen in die leeren csv kopiert und danach wieder im neuen Projekt importiert. Dann hab ich noch alle Programmblöcke, Tasks, Visualisierungen und auch Modbus TCP Master u. Slave und auch Modbus COM Port Master und Slave in das neue Projekt kopiert. Weiters hab ich alle notwendigen Bibliotheken im Bibliotheksverwalter eingefügt. Dann noch ein paar kleine Fehler korrigiert (ich musst einen anderen Block zum Lesen der Uhrzeit nehmen) bis ich das neue Projekt fehlerfrei übersetzen konnte. Dann konnte ich es auf den Wago Controller übertragen und direkt starten. Es sieht so aus, dass alles läuft. Gruß 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 mikek10 on Ethernet/IP 4.6.0 causing exceptions? ^{CODESYS Forge talk (Post)}
Hi, I have a project currently in development, it has a number of Ethernet/IP devices (18 adapter devices with Codesys as scanner, another scanner device with codesys as adapter). This has been stable whilst on factory floor for several months (though prior to that I did have some Ethernet/IP issues which were resolved by adjusting RPI rates). Today I tried updating to Ethernet /IP 4.6.0 from 4.5.1, subsequent to this I had 2 exceptions in a 2 hour period, I reverted to 4.5.1 and have had no further exceptions. Note I do have a device (Zebra printer) that frequently times out and reconnects, this does not seem to cause any issues in operation and does not cause any exceptions with 4.5.1. I believe the root cause of this is on the Zebra side, however there does not seem to be any adjustment I can make to prevent the time outs. Information from device log is in screenshot attached.

Post by climblinne on Calling OPC UA Methods from UaExpert ^{CODESYS Forge talk (Post)}
Hello, I hope someone could help me. I installed the newest Codesys 3.5 SP 20 Patch 1. When loading the demo files from @i-campbell I can upgrade them to the latest version and everthing works on the OPC-UA client side as expected (object "a" is visible, I can use the "ExampleMethod"). Now I * remove the "Information Model", * delete the "OPC_UA_Symbols Objects", * Add "Information Model" again * add "TestRootObjectType" again and "Generate IEC declarations" * and search for mapped instances (to get instance "a" again) Very good still working as expected. Now I delete the OPC_UA_Symbols and add it again referring to the "objecttest" from 16.9.2020. Also I redo the steps from above. The result is now, that I can't see the "a" object in the "Root/Objects" folder. Why ist this and how can I make it running? I think, it could may be a different version of the UA configuration file. I tried to build my own model definition files and got the same problem (but I am really not an expert). When someone has a actual model, which is also running in the actual Codesys I would be very grateful. Or even better, how to make the correct model in e.g. UA Modeler SW (I followed the description https://documentation.unified-automation.com/uamodeler/1.6.0/html/howprojnet_sec.html).

I've checked the directory permissions and ensured that the path is correct. Has anyone else experienced a similar issue or have any suggestions on how to resolve this? Any help would be greatly appreciated. Thank you!

My PLC is WAGO PFC200 Firmware Revision 26. target After updating WAGO_Devices_and_Libraries with newer Firmware 27, CODESYS wants to update all libraries to new versions. I will only add that I did not update the Firmware in the PLC. After compiling the program, I received the following errors: ------ Build started: Application: Device.Application ------- Typify code...

After returning to version 1.5.3.0, the problems disappeared. Probably the version number of this library is responsible for supporting the appropriate Firmware Revision. Can anyone confirm or deny my suspicions?

Hallo zusammen, hi all, ich habe den gleichen Fehler. Auf einem Raspberry Pi geht der Fehler weg, wenn ich alles bereinige und dann vollständig übersetze. Wenn das Projekt im Codesys Development System wieder neu geladen wird ist der Fehler aber wieder da. Mit eine Win V3 x64 PLC kann ich den Fehler nur unterbinden wenn ich auf der HMI das VUM_Login einbinde. Dieses brauche ich aber nicht, da ich die HMI für das User Management selbst gestaltet habe. Das funktioniert auch. I have the same error. On a Raspberry Pi the error goes away if I clean everything and then compile completely. When the project is reloaded in the Codesys Development System, the error returns. With a Win V3 x64 PLC I can only prevent the error if I integrate the VUM_Login on the HMI. But I don't need this because I designed the HMI for user management myself. That works too. Anyone have an idea to fix this problem. Many thanks

I have a DFRobot RS485 temperature & humidity sensor (SEN0438) connected to my Raspberry Pi via a USB to RS485 adapter. I am able to connect and read the sensor data when running a python code locally. However in Codesys, I encounter this error "A bus error has occurred." and "There was no response in time". Could this be because of Modbus Server Channel and Modbus Server Init configuration on my part? Admittedly I am new to Codesys. To get to this stage, I: 1. added some lines to CODESYSControl_User.cfg 2. added "Modbus_COM" in Codesys and set "Serial Port Configuration" under "General" 3. added "Modbus_Master_COM_Port" in Codesys and checked transmission mode is set to "RTU" 4. added "Modbus_Slave_COM_Port" in Codesys and checked server address is set to 1 (also set 1 in my sensor) 5. added 1 channel and 1 init for "Modbus_Slave_COM_Port" under "Modbus Server Channel" and "Modbus Server Init"

Post by timvh on How to implement an interface (IElement)? ^{CODESYS Forge talk (Post)}
See: https://forge.codesys.com/prj/codesys-example/element-collect/home/Home/ This contains an application "OnlineChangeSafeLinkedListExample". What you should do is create a new interface which has your "Priority" property. Then your FB should extend the base element function block and implement your own interface: E.g. FUNCTION_BLOCK MyElement EXTENDS COL.LinkedListElementBase IMPLEMENTS I_MyInterface Then the __QUERYINTERFACE does the magic to check if your "element" also implements your interface. Something like this: // Compares this element with itfElement. // Returns 0 if the elements are equal, < 0 if the element is less than itfElement, // > 0 if the element is greater than itfElement. // This method will be called from sorted collections (e.g. |COL.SortedList|) to sort the elements. // IMPORTANT: The underlying value to be compared with MUST NOT be changed during the lifecycle of the object. METHOD ElementCompareTo : INT VAR_INPUT (* The element to compare*) itfElement : COL.IElement; END_VAR VAR itfIntElement : I_MyInterface; xResult : BOOL; END_VAR // We use integer iInt1 for sorting. xResult := __QUERYINTERFACE(itfElement, itfIntElement); IF xResult THEN IF iInt1 < itfIntElement.Priority THEN ElementCompareTo := -1; ELSIF iInt1 > itfIntElement.Priority THEN ElementCompareTo := 1; ELSE ElementCompareTo := 0; END_IF ELSE ElementCompareTo := -1; END_IF

Post by programmierer on Implementing UDP Communication ^{CODESYS Forge talk (Post)}
Hello everyone, I hope you can help me with my problem. I am new to programming and am currently working with a WAGO controller in our lab, which controls a heat pump. My goal is to send the electrical power of the heat pump (Pel_WP) via a UDP connection to a specific IP address. I am using Codesys version 2.3 and following the guide I found here: https://forge.codesys.com/forum/de/396/genmed-Konfiguration%20der%20UDP%20Kommunikation%20Cosesys%20S7.pdf. I have adapted the guide to suit my needs. The data sending works since I can force the reception value Pel_WP and the data is sent accordingly. However, I am having trouble with the receiving part. The reception value is not being correctly received, and the diSocket variable shows -1. The connection between the heat pump and the WAGO controller seems to be set up correctly, as the heat pump is listed under the communication parameters with the correct IP address. I have also attached images to provide a better view of the setup. I would greatly appreciate any support or suggestions for a solution. Thank you in advance!

Post by mondinmr on First IO address of a CAADiagDeviceDefault. ^{CODESYS Forge talk (Post)}
I have a device CAADiagDeviceDefault: IoConfig_Globals.Axis_A In our library, we perform introspection of the Etc_SlaveDiag. In that case, we have connectors, and by searching for them by address, I can find them in the IO mapping using the offset and size provided by EtherCAT. However, a Lenze i700 drive, instead of placing the IO mapping in the Etc_SlaveDiag device, places it in a sub-device CAADiagDeviceDefault. So, when I perform introspection, I cannot find the IO correspondences. Yet, in the CAADiagDeviceDefault, I do not find the connectors and cannot do the matching. Is there a way with a pointer or reference to a CAADiagDeviceDefault to obtain the address of the first input and the address of the first output? This is because we have our own motion library with many EtherCAT devices that automatically configure the mappings, but I can't manage to do so with the Lenze i700.

Hello, I have a robot configured as a Generic Ethernet Module under Ethernet/IP Scanner. I can not see the change of state of the outputs coming from the robot on the codesys side in real-time. (The robot has it's own internal program that would changes the values of remote outputs 0-3 off and on). Also when I send data down to the inputs of the robot it doesn't transfer over as expected. As an example I'll send to the robot's input bit 0 a value of 1. It doesn't see that value change. However, when I write that input bit 0 back to a value of 0, the robot changes state and shows a value of 1. And if I change the state of a different bit, the other bits update properly, except for the bit that I changed. Any advice would be greatly appreciated, and if anything else is needed let me know.

Post by bjarne-pagaard on Communication between applications on same device/controller/runtime (Win RTE 3.5.20.20) ^{CODESYS Forge talk (Post)}
Hi, I would like to divide a project into multiple applications - as a minimum: one handling visualization and Alarm Manager, one handling I/O and plant control logic. But how to exchange variables between the applications? What have you done to get such a solution? In versions 3.5.19 and earlier, you can have Child applications, where the children can access a GVL in the Parent application. Children apps is no longer possible in 3.5.20 - but you can have 'sibling' apps - Several apps directly under PLC Logic, that is. But how do they best communicate? The Communication Manager / Data Sources Manager is sort of possible via OPC UA, but it seems like overkill and with some limitations - for example no ARRAY OF STRUCT possible this way. If you have separate devices in your project, you can exchange data via 'CODESYS ApplicationV3', but not other applications in the same device (see attachment Datasources.png). You can do it via 'Select the project type'->'Other Project' and select the same project file, but this leads to crashing the Development system when working with the variables afterwards. It would be great to hear your thoughts / experiences on this topic - Bjarne

Post by mainak on Opaque NodeId in the OPC UA server ^{CODESYS Forge talk (Post)}
Hello all, I am using the OPC UA server with my custom information model. I have used the communication manager to add my information model under my application and created instances from OPC UA types. I see that the created instances in the OPC UA server has some opaque nodeid (attached screenshot) and I want to change that. Therefore I have the following questions: 1. Is there a way to configure the NodeIds of instances in the OPC UA server? I tried to edit it using the UaExpert client but got error "BadNotWriteable". is it possible to configure it somewhere so that the nodeids can be changed using an external client? 2. Is there a way to define the rule for creating instance nodeids within the codesys IDE? 3. Is it possible to create the instances before e.g. using a modelling tool like UaModeler and import them as part of the information model and use them later? Using the communication manager, I can only create instances from types. I couldn't find a way to map my existing instances to plc tags from my application. It would be nice if someone could help me with these issues. Thanks in advance. :)

Hi, Communication with the ADS1115 is actually simple. 1. write config 2. write address pointer 3. read conversation register The ADS1115 works like a multiplexer. This means that you do this individually for each channel that you want to read. e.g: Channel 1: write config > write address pointer > read conversation register Channel 2: write config > write address pointer > read conversation register Channel 3: write config > write address pointer > read conversation register Channel 4: write config > write address pointer > read conversation register then you start again from the beginning You can also omit individual channels or read only one. It doesn't matter. I have written the driver so that I can also use it on the TCA9548. The driver is from Stefan Dreyer. In your case, the driver works and communication with the ADS1115 is running. As you can see, the cfgWrong:=FALSE If you could not write or read data, cfgWrong:=TRUE; This means that either something is wrong with your ADS1115 or you have connected something incorrectly. Question: what voltage do you want to measure?
