Post by jegerjon on Testing of Codesys program ^{CODESYS Forge talk (Post)}
I have a simulation function that toggle xSimActive. I map all IO variables to "IO GVLs" when xSimActive=0. I map IO corresponding SimIO GVL to "IO GVLs" when xSimActive=1. Then I write code for the simulation program that runs when xSimActive=1. Typically increase flow corresponding to pump speed, simulate tankfilling corresponding to flow and so on. I made a FC that require a correct code to activate simulation to avoid unintended activation by service dept. When comissioned remove any possibility to activate simulation. Super when officetesting and supporting service dept. + cheap as it requires no additional equipment, and it is easier to support customer later on in the life cycle as you can test proposed changes without setting up a testlab.

Post by macros8 on Translation - How to get text as reference in Frames translated? ^{CODESYS Forge talk (Post)}
Hi, thanks for the link. Maybe I create elements in incorrect way. I always use Interface Editor to create variables which are used inside element (see pics). After that I place element in my visu and use Reference property to link variable or set the value. In that case the value of string is not transferred to general text list for translation as I mentioned before. Do I have to all properties which influence behavior of my element create in Frame configuration instead? What´s the difference to the Interface editor? Thanks a lot. M.

Post by jdjennings1962 on Trouble accessing Math functions in OSCAT library ^{CODESYS Forge talk (Post)}
Hi all, I am trying to utilize the ARRAY_SDV standard deviation function, part of the Math group in the OSCAT library downloaded from the CODESYS store. My Codesys version is 3.5.19.10. When I add the OSCAT to my Library, it shows a subset of the library (Standard) as fully installed and signed (see pic). However, the Math functions are not in this Standard group. The Math functions I need can be viewed as source code in the full OSCAT_BASIC, though this the symbol next to this library suggests it is source only and not fully installed. When I try to declare an instance of the ARRAY_SDV function in a program, it is not known. I have tried reinstalling and Building . . . Any help would be greatly appreciated. Jeff

Post by matt-s on HMI Pushbutton/Move Instruction ^{CODESYS Forge talk (Post)}
I am having an issue where the manual start/stop push buttons on the HMI are supposed to take the pumps/blowers out of auto. The logic I have attached works for the pumps, but not the blower. From what I can tell it is the exact same logic, but it is not writing a 0 to the Auto PB variable. Attached is the logic, cross reference list to show nothing else is writing to it, and the HMI screen. Any help? Am I missing something? I am using a Groov Epic PR1, my software version is 3.5 SP19 Patch 5 32 Bit.

Post by sumit on Not able to see input data coming from eip adapter on codesys ^{CODESYS Forge talk (Post)}
dhumphries, I changed the datatype this time from BYTE to USINT (because that's what my adapter is sending: array of uint8_t). The text "New Help String" you saw in previous screenshots is just the description of the input/s (it can be anything). I also looked into the logs (see attached) for that ! sign next to the device, I found that connection is being timeout. I tried some suggestions from online such as increase the RPI but still got connection timeout issue, also by changing the datatype, I still don't see incoming data from the adapter, although its visible on wireshark. thanks,

Post by phoward131 on Text List Fallback Value ^{CODESYS Forge talk (Post)}
I am relatively new to Codesys and I'm trying to develop an HMI that displays what mode a particular device is in based on an integer value. I am currently using dynamic texts with a text list which works fine but I am looking for a way to display a particular string (ie 'Unknown') when the index doesn't match any of of the indices in the text list. I can enter 'Unknown' in the text property of the text field element which works as expected but it displays the single quotes on the visualization. How can I escape these quotes to simply display the word Unknown? Thanks!

Post by struccc on Release SP20 - Changes in behaviour? ^{CODESYS Forge talk (Post)}
This... is not very practical for me - as I have a bunch of different classes - it's just doesn't seems to be very practical to define a NULL for each of them... Something like this I use in parameter definitions. For example: VAR_INPUT refVFD_Drive : REFERENCE TO FB_VFD_Drive := GVL_DUMMY.Dummy_VFD; END_VAR I use this to prepare objects for code I don't control: Typycally visualizations - had many troubles with references set on the fly, right before opening a corresponding visualization... And yes, the instance in GVL_Dummy reports itself as "Fake", so it does not influence the actual application at all. Actually this way I could invalidate a reference, just to set it to a "Dummy" instance.

Post by david24 on Map in Codesys ^{CODESYS Forge talk (Post)}
Hello everyone, I have the task of programming a map. With the help of the visualization element "Table", I have managed to accomplish this. In the Input Configuration, I activated the option: "Write Variables", so that the user can change the values in the map. To test the program, I select the Online Mode (Simulation).There I change the values in the map. When restarting the program in CODESYS, the changes in the map are no longer there. Does anyone know an approach how to save the changes in the map? Thank you for your support Best regards David

Post by danwoodlock on Rpi zero w lost license after 4.11 update ^{CODESYS Forge talk (Post)}
Hello all, Encountered an issue with my zero which seems to have happened after the 4.11 update. It now runs in demo mode (2hr) and I am trying to see what the appropriate steps are prior to contacting codesys directly. Background: I recently did a fresh install of w11 on my pc, so it seems "c:\ProgramData\CODESYS\Licenses\" only has information related to my pi5, which I licensed just this past Friday. I have all my license documentation about my rpi zero as far as the emails received, but when I try to claim using the ticket number it says its already been used, or something to that effect, which it was. Currently trying to perform device license reader, which is taking some time.

Hello everybody I want to controll a stepper driver from Leadshine (EM3E-556E). The EtherCat slave is CiA 402 compatible. Because of this I bought the Softmotion Light Package from Codesys and implemented it in my project. I rightclicked the EtherCat slave and added the Softmotion Light axis. But now the error message shows: "The license is missing or invalid. The PLC runs in demo mode." What have i done wrong? I use Codesys 3.5.17. Is it possible that the stepper driver is not compatible with the Softmotion license? Thanks for all your help

Is it possible like G-Code streaming processing (like FANUC or SIEMENS DNC Function )? Or Does anyone know the tips for CODESYS Motion to start moving long Long G-Code File quickly? I have to wait long time after "Start" button to start moving, I have to wait finishing interpreting whole G-Code file, ( and I have to prepare huge buffer to store. ) Now, I'm working on my CNC Project using SMC_ReadNCFile2, and SMC_NcInterpreter to preprocess G-Code. I tried to set SMC_Interpolator.xExecute to true to Start while after SMC_NcInterpreter processed more 50-line of G-Code, but that not worked, I had to wait SMC_NcInterpreter processed all lines to start SMC_Interpolator. G-Code have about 2000 lines of XY of G01 (or more over.. ) of short segment that a CAM software has exploded from NURBS Curve.

A scan from the "Diagnostics live" tab of the EtherCAT master gives slave status. What I have tried: Restarting gateway in system tray. Exiting system tray gateway and reloading it. Turning off firewall. Contacting ABB support multiple times. Any help appreciated.

Post by wbj0t on connect IDE to plc that uses modem ppp ^{CODESYS Forge talk (Post)}
Hello everyone! I have an PLC device that uses modem ppp connection to the internet with white IP. Device PPP connection with modem operator established, so I can connect to this device via SSH also within Codesys IDE (check version, info, etc...) BUT, I cant establish connection to this device in the device gateway options for application upload and debugging. How can I do this? Im trying set my device remote IP and port 11740, but, as I understand, it is wrong decision, because the next logic in this connection: local W10 service (Codesys Gateway) listen on 1217, then (some how) this service scanning local networks for seeking any local IP which listening on port 11740, and then connects and writes there. OR IM WRONG?:) W10 tool 'Test-NetConnection' with parameters 'ip -Port 11740' succeeded with True. Need some help, please :)

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

Today, I went to install the visualization M locense as well because I went over the variable limit and am getting a "servernotfound" error in codesys when attempting to activate. I also tried to follow the advice in some other threads and install using a license request file on the web interface but am getting a message saying "An internal error occured" when attempting to install the license. Can anyone help me get this up and running? Thanks for your time.

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.

Obviously it works in a visualization, but because I will have an HMI that has it's own system and I will have to send variables to this HMI via an OPC UA connection, I need to be able to get a text into a string. I tried using the VisuElems like this, but it only returns an empty "" and nothing else.

Post by fajean on CODESYS control on RPi starts, shortly runs, then exits ^{CODESYS Forge talk (Post)}
4.11 appears to solve the problem. Thanks for your help. I had first installed the 64-bit version of RPiOS, but looking at various posts and the product's page on the store which only lists 32-bit compatibility, I downgraded to the 32-bit version. I did this before trying 4.11, and it did not solve the problem. Thus my working system is 32-bit, and I am wondering if I can go back to 64-bit or not. An 64-bit OS is not listed as compatible on the store's web page, but when installing there actually is a 64-bit version listed (automatically chosen when installing on 64-bit, but otherwise greyed out). Is 64-bit supported and the website is out-of-date, or is that some kind of work-in-progress?

I wanted to try switching the visualization depending on the device type. To do this, I used a smartphone to access it. I can see via breakpoints that the Smartphone visualization is selected, but the visualization of the normal monitor still appears on the smartphone. Could there be a problem with the libraries, or why is the device not assigned the correct visualization page? I dont know how do further debuggin or troubleshooting.
