Post by ewi04 on How to upload application file to remote controller (offline) ? ^{CODESYS Forge talk (Post)}
Thank you very much for your time and replay! Sounds like a good idea. Unfortunately, I have no other option to run the code from the running plc. So, I can’t stop any services. If anyone has the same problem, I've gotten a little closer to understanding it: Sometimes the copied files are empty after the restart. The update code checks if there are any empty files. Before I turn off the device, everything is okay. But after starting, some files are suddenly empty and that cause the problems. I don't know why this happens.

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 albzen on EtherCat Slaves diagnosis ^{CODESYS Forge talk (Post)}
Hello everybody, I'm working on a RunTime Plc (Codesys 3.5.16/18.20) connected to an EtherCat bus with many devices. The bus has some communication fault but I don't know how understand which is the device or the cable that has the trouble. To understand the cause of the problem I would like to read the WKC (Working counter) of the devices (0x0300...0x030C), how is explained in EtherCat documents, but it seems that the read of the counter is disabled. Attached there is an extract of the Ethercat document. Can anyone give me some advice about how and with function can I read it. Thank you in advance!

Hello, You use the WAGOUpload tool. You can download it on the download center of WAGO. Make a backup and restore it on the new device. (if can check the remanent data to copy the persistent variables if necessary) You can also use a SD card, go to the WBM copy it the image to the SD card and restart the other controller on the SD card. In the WBM, copy it back to the internal flash. If you contact your local Wago office, they will more than probably help you. There is also a WAGO forum. RP,

Post by alez on CANopen safety , SRDO error behavior ^{CODESYS Forge talk (Post)}
I have a project in which there is a Safety device in CANopen, and the PLC interfaces with it as Master. I would like to understand if it is possible to set the behavior in case one of the SRDOs that I receive from the slave is no longer received. From what I have seen, if the SRDOs are not received, the CANopen safety status becomes "Not in progress" and the mapped variables freeze at the last value detected. I want to understand if it was possible to set the variables connected to the SRDOs to take a default value (e.g. zero) in the event of a CANOpen error during reception.

Post by peterned on Array to String ^{CODESYS Forge talk (Post)}
max. string length in Codesys is 255 chars. It's not possible to cram 20,000 things in a string. If you need to send the data to another device, send the whole data[] array (as byte array, without doing anything to it) and extract the information on the other end. As each struct member has a fixed size (81 bytes, as per you declaration), this will be easy. To save some resources, consider declaring string lengths - e.g. if the max possible length for key is 10 chars, declare it key: STRING(10); and it will occupy 11 bytes instead of 81

Post by mubeta on Reset problem with CMZ SD/SVM drive ^{CODESYS Forge talk (Post)}
In a recent project with SoftMotion 4.15.0.0, where I integrated two SD drives from CMZ (from catalogue EDS and not imported), on CANopen bus, I found that the SoftMotion MC_Reset function does not reset the drive faults. Even if the drive is in fault, either on the device or on the drive at the CoDeSys level, the function does not reset, instead reporting the error code: no error to reset. Finally, I had to connect the reset bit of the ControlWord directly to a tag in my program. Something I never had to do on other drives: Lexium, etc. all reset simply with MC_Reset.

Post by jnoyau on Visualisaion while in simulation ^{CODESYS Forge talk (Post)}
Hi all, Im new to Codesys 3.5, and am in the process fo making a visualisation i'd eventually export towards a Wago device. The issue I'm having currently is that when I compile and connect to the simulated program, my simulation won't launch. On the Visualisation tab, all I get is a text message (where previously there was my prepared visualisation) that says "The visualisation awaits a connection. Start the application" One thing to note: I work with Codesys 3.5 in french, so this is a rough translation. And a second: I'm not getting any errors nor warnings about the visualisation tab itself upon compiling Is there a step i'm missing after launching my simulation? Or would it be some really specific issue caused by the way I've set up my program? Thanks, J

Code examples are given here: https://content.helpme-codesys.com/en/CODESYS%20Scripting/_cds_access_cds_func_in_python_scripts.html However, I have a question how to print the whole Project tree and not just devices? Of course I need to remove check: if treeobj.is_device: But simply removing this test condition will not produce what I want. I need to print PLC Logic, Application, ad other nodes in the Project tree. Where to find this documentation?

Post by timvh on Communication between applications on same device/controller/runtime (Win RTE 3.5.20.20) ^{CODESYS Forge talk (Post)}
If you have a Windows system (RTE), then why not run the CODESYS HMI as separate controller. This could easily be moved to another PC if required. In the HMI you could also still use the Symbolic Var access as part of the Data Source Manager, although maybe OPC is the preferred way to make it more future proof. Or what about the Remote Target Visu. Then you can reduce the load of the main controller, while still only having to create one application including Visualization. This is now also supported for Linux systems. See: https://content.helpme-codesys.com/en/CODESYS%20Control/_rtsl_target_visu_for_linux.html https://content.helpme-codesys.com/en/CODESYS%20Visualization/_visu_execute_remote_target_visu.html

Post by pernockham on Linking to IO during runtime with hot swap? ^{CODESYS Forge talk (Post)}
I have a project where a single PLC shall control multiple nodes (up to 10 units?) with IO connected through profinet. Ideally each node should be identical however with time I see situations were different setups/configurations will be used. Codesys PLC (GVLs) |Profinet | |--PNIO-node-1--| | | AIO, | | DIO, | | CNT etc. | |--PNIO-node-2--| | | AIO, | | DIO, | | CNT etc. Ideally I think of a configuration through yaml/xml-files (the assignment/linking of the profinet nodes towards GVL-variables in the PLC as well as scaling, channel configration etc.). Would be grateful if someone could suggest library/-ies that can handle the following: - Verify what IO is connected to a device/node. - Hot-swap/assign link for IO towards GVLs, either automatically or through a HMI.

Post by jackbrady on Function Blocks and arrays of function blocks ^{CODESYS Forge talk (Post)}
Hello, I am new to Codesys and PLC programming in general (please go easy ha!) I'm not looking for code to be written for me just some help and pointing in the right direction. I am writing some code to send commands to a relay based on input values (to put it simply). Quite basic stuff. I have wrote a function block that takes a global variable (Open_command:BOOL) and outputs to another global variable (Opened : BOOL). The function block is simulating a device so I'll eventually get the globals from that. I now need to create multiple versions of this function block/ device (lets say 100) but I need each iteration of that function block to reference it's own relevant global variable. I think that the best way of doing this would be to use arrays, although I could be wrong. I am aware that for up to 100 instances I could very well manually assign everything but that seems rather time consuming and I want a fancier way of doing it. Here is a very basic example of what I am looking to do, please note I have not written this in proper code it's just to show what I mean. Global Variables V[0-100] int Open_command [0-100] Bool Opened [0-100] Bool Function Block var input x : BOOL Var output y : BOOL if x then y = TRUE ELSE y = FALSE The input to my function block will be Open_command, output will be Opened Example code. If V[x] > 10 then Open_command [x] = TRUE ELSE Open_command [x] = FALSE (So when V1 goes above 10 I need Open_command1 = TRUE therefore initiating FB1 output. V2 > 10, open_command2 = True > FB2 output V3 > 10, open_command3 = True > FB3 output ... ... ) What I can't seem to figure out is how to tie all this together, I have read through the codesys documentation and if anything it has confused me more! ha. Apologies for the poorly written post but hopefully you understand what I am trying to get at. Thanks, Jack

Post by alexgooi on OPC-UA and other communication questions ^{CODESYS Forge talk (Post)}
Dear forum, I currently have a big question mark above my head, and maybe this forum can shine some light on the situation. I recently updated to Codesys 3.15 SP19 Patch 6. And now I’m trying to setup the OPC-UA server, besides that I’m trying to connect to the controller with the Codesys V3 (Ethernet) protocol. OPC-UA I have installed the correct licenses on my controller (Runtime and communication). I’m able to connect to the controller with an OPC-UA client, and I’m able to browse the tags, so far so good. Therefore I’m assuming that the OPC-UA server is running on the controller. But now the strange part, in the device security settings I have set the communication Policy to BASCI256SHA256 ( I also have tried the other ones) and the communication mode is set to secure if possible (I also have tried all the other ones) (see picture). With these settings I would assume that I would only be able to login with a Basic256SHA256 policy with a client. But the opposite is true, I am able to login using the no policy mode and when I set it to Basic256SHA256 the client (UA-Expert) notes that this policy is not available on the server. I then check the certificates and I noted that there is no certificate for the OPC-UA server, I tried to generate one but it gave the error that the certificate has not been created by the device (See picture). To summarize I have no clue what is going on, and the controller does the opposite of what I would expect. Codesys Ethernet V3 driver I have a HMI connected to the same controller using the Ethernet V3 driver. But this will not connect. I tried all the Protocols (see picture), with and without the username and password enabled. But it will not connect, when I scan the available servers I can see the controller with the port number that I am expecting, so I’m assuming that the Codesys V3 ethernet driver is up on the controller. Does anyone can give me some direction, because the stuff that I tried doesn’t make sense to me. Thank you in advance

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
