A branch is a branch (doesn't grow back to the tree). But what you are trying to do is use several XORs. See attachement.

Hello. I'm trying to use RecipeManCommands.ReloadRecipes Method for getting recipes from files. When I call the method it does not generate any error but also not reload any recipe to the recipe definition. Actually I have 6 recipe files on the directory PlcLogic. The rest of the methods work creating recipes, saving to file, etc. Does any one have the same issue? it is something to be set on the recipe manager?

Post by mikek10 on Error IoDrvEthernetIP: Connection Failure. (16#1) How to solve ^{CODESYS Forge talk (Post)}
Your connection configuration should look something like the attachment. Consuming assembly O->T will be the hex of the assembly you want to reference for output data - I want 102 (DO Data Only) shown in the Wago web page 102 = 16#66. Producing assembly (T->O) is the assembly you require for input data - again shown in the Wago web page - I want 108 (DI Data Only) or 16#6C Then set the number of bytes as per the data in the Wago web page too (both 2 in my case)

Post by mozed on Connection to device closed ^{CODESYS Forge talk (Post)}
Hello I am using an OpusA3 with version 3.5 SP17 Patch 3 as part of a project. I had no real problem before I encountered a problem that blocked me. The detection of the OpusA3 from Codesys is done correctly. The gateway is well configured and if I ping the gateway or the OpusA3 I receive the response correctly. The problem is that when I try to connect, the Opus screen freezes and a few moments later Codesys displays an error message ("connection to device closed"). I tried to change PC, to update the runtime, to change OpusA3 but the problem remains the same. I'm a little lost knowing that before it worked without problem. I went back to a previous version of the project (where it worked correctly) but the message still appears. Do you have any clues to solve the problem? Sincerely,

Post by rh-pk on v3.5 SP19 - Modbus TCP Devices - Channel Limit? ^{CODESYS Forge talk (Post)}
Hi, i found a solution for me. I had installed a 'old' version of CoDeSys (3.5.18 P5). I tried to add channels there, which works fine. I created a new project, added an Ethernet-Port, added a Modbus-Master and then I copied the ModBus-Slave from my working project to the new project. Now I could add more channels. I add the channels 10 and 11. Then I deleted (please make a backup before :-) the original ModBus-Slave in my working project and copied the extended Slave back to my working project. Surprisingly it is now possible to add new channels. Maybe this will help you.

Post by dhumphries on Toggling Visualizations using HMI Physical Buttons ^{CODESYS Forge talk (Post)}
Nothing wrong with ladder, in a lot of applications it is simpler than ST or CFC, you're a lot less likely to have syntax issues in a ladder diagram than in structured text as long as you stick with traditional ladder elements. Your attempt was almost valid, but you tried to change the currentvisu variable using a blend of structured text and ladder, which isn't allowed. You need to use the MOVE operator and define the visualization name as a string on the input side and the visuelems.currentvisu as the target on the output side.

Post by alexgooi on Modbus writing on value change ^{CODESYS Forge talk (Post)}
The way I usally tackle this is by syncing only words (then you are able to use the FB above). If you then want to write a Boolean simply type it like this. Value[1].0 := Bool1; Value[1].1 := Bool2; Value[1].2 := Bool3; Uints have the same number of bits than a INT/WORD so these ones will work as well (they are only represented diffrently). A Real will work but you will loose some infomration in the conversion. If you want to keep the information you can convert 2 words to a float with a function (for example with the IEEE-754 standard) . In this way the syncing to the server is very simple and in the Codesys Program you decide what part of the word you want to use.

Post by mbmik on IoDrvModbusTCP_Diag not defined when using MODBUS ^{CODESYS Forge talk (Post)}
Hi Im trying to setup a Weidmüller WL2000 to run with MODBUS, to get some data from a server. Codesys V3.5 SP20. The issue is, that whenever i attach an ethernet port and add MODBUS Master und also a Slave, codesys will compile the project, but there always seem to be some remaining errors, which or only visible, when setting the messages window to "Pre-Compiled". I tried a lot of stuff to get rid of these errors, but cant find to seem the reason. New installation of codesys, cleaned project, setup completely empty new project, manually adding libs. Nothing helps. Any help is apreciated. Maybe we are doing something wrong.. Example Project is available, if somebodey wants to take a look. Greetings and thanks alot

Post by alexgooi on FB_INIT in library ^{CODESYS Forge talk (Post)}
Dear Forum, I currently have a challenge. I have a library with some communication classes. These communication classes need to be linked to an interface like this: Devices_and_controllers.Comm_Frame.Modbus_GVL_Link.KNX_TCP[Interface_Index] := THIS^; This is executed via a FB_Init() method. When I try to do this in a program this works fine. But when I declare the FB_Init() in the library the FB_Init() method is being called but the link is not made (interface still has the value 0000000000). The Objects and interfaces are defined in the library (GVL), so I’m assuming the data should be there. When I call the FB_Init method explicitly in the program it also works fine. Whys is this not working when it is all defined in the library? And is it even possible to create a structure like this in Codesys? Kind regards Alex

Post by jaspergain on Non-existing identifiers ^{CODESYS Forge talk (Post)}
Hello, I got a bit of a weird issue going on which is kind of annoying. So recently we switched a lot of Modbus IO to EtherCAT, as we were having issues with stability. All works fine, which is great. But sometimes when I change the program I get errors claiming that identifiers are not defined. Meaning I can't go online. See the picture below. I believe this is because some of these identifiers were used with Modbus, and they weren't properly removed/deleted? A clean all temporary fixes the issue, but it comes back again after a while of changing the code, and building. Any way to fix these non-existing required identifiers, or even find out where they are required? Thanks for the help in advance. Jasper.

Post by rafael on Wbm/runtime and visualization login ^{CODESYS Forge talk (Post)}
Hello everyone, I’m trying to understand if it is this way or I can change it. I’m making a PLC code and visualization screens, the ideia is to operate via webvisu some controls. So i made a code, made some screens and when i try it in my web browser, first it asks me to insert te user and password of the wbm/runtime of the plc (user: admin, password: wago by default), then i can acess my screens but I have to login again with the user and password that i created in the visualization user managment. My question is: is there a way to disable this first login to the visualization screens (webvisu)? Or create another user/password for this first screen? I have a PFC200 and a Edge Controller, both are working the same way. Thanks in advance Thanks

Post by paulg on Converting hex bytes to float ^{CODESYS Forge talk (Post)}
I'll be capturing a hex stream over serial into a RasPi and I'd like to convert a group of bytes into a float. I see this is available (https://content.helpme-codesys.com/en/CODESYS%20Development%20System/cdsoperatorrealto.html) but not its inverse (i.e. BYTE_TO_REAL). The packets will be 18 bytes but I'll be selecting 4 byte segments from the middle, swapping byte endianness (i.e. changing 0x51847641 to 0x41768451), and converting to float; I believe they adhere to IEEE 754. Is there a pre-built function for some or all of this, or do I need to follow (https://forge.codesys.com/forge/talk/Engineering/thread/dc5829c7ea/)? Thanks!

Post by yannickasselin on codesys VLAN tagging ^{CODESYS Forge talk (Post)}
Hi, I am looking for exactly the same thing. I would think that using a layer 2/3 managed switch should work but I am not convinced. I would like to test it in order to see if it would be possible to run many Codesys Docker instances on a server and run only 1 ethernet cable from the server to a managed switch closer to the machines beeing controlled instead of having to run multiple long ethernet cables. I was going to buy a managed switch in order to test it but I want to first make sure it is possible and I want to figure out exactly what kind of switch I would need. Is this even possible? I think this is a feature that would be very useful paired with "Codesys Virtual Control SL". Thank you

Post by danielbeers on Automation Server + Pi Gateway + PLC w/ CAN ^{CODESYS Forge talk (Post)}
Hello, I have a project using some EPEC PLC's. Some of them are programmable using Ethernet and some use CAN. We currently have a Raspberry Pi that is acting as a gateway to the Codesys Automation Server and is successfully working for the PLC's communicating over ethernet. I am trying to achieve a similar result for the PLC's that have only CAN access. I have PEAKCan drivers on the Pi, and can successfully send/receive messages. But the Gateway does not recognise the PLC when scanned from the Automation server online. Is there a library or service that exists to translate the CAN messaging, to the Edge Gateway, and be able to achieve remote access with the Automation Server? Or is this not possible without creating something custom? Cheers, Daniel

Thank you so much. This worked. Waht im trying to do here is to automatically tag each sensors, valves and so on. There is a preatty nasty tag system i working on. "_320" is not alloved. I can have a tag "+4f=320.004-RT001V" In codesys I want to build the FB in folders. -4f | --320 | --001 This is the system structure. Inside here is all of the sensors and so on. But with Codesys, I cannot tag this like this. So what I'm trying to do now is to Make a folder for the building "4f" and one for the system "320", and a POU _001. Is there a way in init to get folder names?

Post by struccc on HTML5 Controls - string(>80) values ^{CODESYS Forge talk (Post)}
Dear all, does anyone have experience with HTML5 controls recently? CODESYS 3.5.20.30 / Visualization 4.6.0.0 I'd like to create a simple lightweight text editor, with proper multiline handling, cut & paste, scrolling, etc. And it seems to work fine, just have problems with strings longer than 80 bytes.... Declaring a variable sText1 : STRING(8000) and referencing it in the HTML5 Controls corresponding value property works perfectly one way: the code receive the data as a string (See log1)... (Note TypeID 1000...) Also sending back the data (seems to work (See log2) except it doesn't change the value of the bound variable. Probably the issue is with using SendSimpleValue method... Naturally, I could do a workaround, but maybe there is a more standard way to implement this... Please let me know if you have any suggestions.

Goodmorning TimvH, Thanks for the reply. I don't know if your solution solve my trouble yet, I am going to see the link you sent me. In the mean time I try to explane better what I need to do. I have a turbine system that get in alarm under some condition (E.g low speed of turbine) and block the itself. When the system is stoped there is no speed turbine and the system cannot start. To give to the operetor the possibility to bypass the alarms, there is an acknoledgement alarm pushbutton. This bypass must not work for everyone but only for those client that perform the login by (User Management). Furthermore, if the user perform the (manual or automatic) logout in alarm conditions, the acknowlegment must be annulled and block the system again. To do this, I need to know if an operator is logged in the page and is working to fix the problem; otherwise the syste must autoturn off again. Now I go to study your solution, if I have explaned better and you have another idea tell me please.

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 julianramirez on ModbusFB write update ^{CODESYS Forge talk (Post)}
Hello everyone, I am testing the ModbusFB library tcp server and so far I am able to create holding registers successfully, however, I am trying to identify after each write which registers got updated (i.e. function code, write value). I can even see the var udiNumWriteRequests, which increases with every write. I noticed that there is logging with the LogStatusInfo method. After I call it I am able to read in the console stuff that I want. Nevertheless, this is only available at the logs and is not easy to decode because it consists on several messages, I would like to know if there is a way for me to retrieve this information from the function itself with pointers or if there is any way to copy the logs messages (assuming that I can filter them with the LoggingOptions to only show what I need) inside the runtime code and not in the console. Thanks for your help :)
