Post by fredruel on ModbusServer became unreachable if reach maximum of 16 byClientConnections ^{CODESYS Forge talk (Post)}
Hello Fraziersedge, the solution of Codesys might be to update your codesys to the lastest version but it was not possible for us. In our Codesys V3.5 SP9 patch 8 I was able to fix this bug. I change my ModbusTCP slave component version or one of the sub component version (ex: SysSocket). Look at the picture in attachement that's the receipe that have work for us. When I got the bug my version of ModbusTCP slave was 3.5.5.0 with SysSocket at 3.5.6.0 and I change to ModbusTCP slave 3.5.14.0 with same version 3.5.14.0 of SysSocket event if I still use codesys V3.5 SP9 patch 8.

Post by trusty-squire on How to revert to previous version library ^{CODESYS Forge talk (Post)}
Hi, I'm experiencing a bug with the latest version of SoftMotion CNC library (4.17), where the 3DPath object in Visu is missing all the important properties. I've verified that a previous app I was working on with library version 4.16 did not have this issue and the issue is duplicated in that project when I update it to 4.17. I've already submitted a bug report, but for the time being I need to revert the project I'm currently working on back a revision. I've tried right clicking on the library but the option to select the version is greyed out. Can anyone help me?

Post by otbeka on CmpCrypto CryptoGenerateHash Not Outputting ^{CODESYS Forge talk (Post)}
Unfortunately I noticed that, and tried: * using CryptoGeteAlgorithmByID within the function call * inputting the raw byte pointer as a testByte * instantiating the _hHash handle within the function body * using a different cryptoID or the raw DINT values from the RtsCryptoID DUT ... to no avail. The pReturn value is also set to 0, which would indicate that it is OK, right? This is odd given that the function is the same within the CryptoDemo example project here, just with a newer version. Is it possible that there is something wrong with the way my bytestring is being set up? I use the following DUTs here: TYPE MESSAGE : STRING(255); END_TYPE TYPE HASH_CODE : ARRAY[0..19] OF BYTE; END_TYPE

Post by pierre on difference between stub file and source file in scriptengine ^{CODESYS Forge talk (Post)}
I included the stub files of scriptengine (codesys python api) in a directory scriptengine of a project. I tried to include librarymanager like that: from scriptengine import librarymanager visual studio code detected an error. It said librarmanager could not be found. Indeed in the stub file, this was library_manager. But if I change it in my code, the plugin doesn t work anymore. I found an easy solution to this problem. I ve just changed the copied stub files.(library_manager -> librarymanager) But I think it would be better if you update it yourself in the future.

Post by pistola on Case Function - Multiple Conditions, Is it possible? ^{CODESYS Forge talk (Post)}
Looking at the help (https://content.helpme-codesys.com/en/CODESYS%20Development%20System/_cds_st_instruction_case.html). I don't think it is possible but I figured I'd ask. I'm looking at have a case that evaluates two variables, instead of having multiple If Else statements I was hoping I could just use a case. Example * Case Var1 & Var 2 of 10 & 10: Instruction Code 10 & 20: Instruction Code 20 & 20: Instruction Code End_Case Obviously I tried typing as noted above and Codesys threw an error. But I was wondering if there was a different way of programming to make something like this work? If not I'll just use a bunch of If Else Statements, Thanks.

Post by hyys12 on CODESYS 3.5 dicovery of PLC modules ^{CODESYS Forge talk (Post)}
I have a WAGO PLC, to which I am establishing a connection. Here I use the autodiscover to register the connected modules. Now, I have tested the in-/outputs of the different modules, to verify they are consistent with how they are physically connected to the PLC in regards to how CODESYS has numbered them. Will CODESYS always number the modules closest to the PLC itself lowest, and the one furthest away, the highest? I am rather new to the program, so I both hope my question makes sense, as well as not being completely obvious. Thanks!

Post by climblinne on OPC UA Method - How to wait for result? ^{CODESYS Forge talk (Post)}
Hello, I am already able to run an OPC UA method in Codesys. Now my question, how can I interact with other tasks (e.g. read an SDO from EtherCAT and return it by the function)? The OPC UA method seems to be called only once (I tried to return BOOL or UINT values). Up to now I only found to do a while loop to wait for the result of the other task. Is there a better way to do it? Is this the way OPC UA functions should be used (for "not too long" function calls) or should I use another mechanism (method: Start, event: Finish, method: getResult)? Regards

Post by sigurdrb on OPC server in "Communication manager" ^{CODESYS Forge talk (Post)}
Hi! I was thinking of switching the OPC server config from "Symbol Configuration" to the "Communication manager" in the device tree. I Have a lot of arrays of structs that I have previously declared in the "Persistent Variable" object in the device tree. It seems as it is not supported to directly expose persistant variables to the OPC server like the "older" way of doing it in the symbol config. Is this correct? Do you recommend to just do it the old fashioned way, or should I edit the structure of the global variable list / persistant data / OPC server and set up the OPC server from the "Communication manager" object?

Post by peterkcontrols on TargetVisu started in windowed or not full screen ^{CODESYS Forge talk (Post)}
Hello, I am using Codesys on an industrial pc with a single monitor. I would also like to have a separate vision software running on the PC and would like to display it half screen. When I run the soft PLC the my visualization screen appears full screen, I would like to be able to set the size of the visualization screen so I can display other software on the monitor. Is it possible to set the width/height of the targetVisu? Anyone try something similar? I would like to avoid having to put it on a Virtual Machine. Thank you

Post by alberto on ExportPLCopenXML is failing ^{CODESYS Forge talk (Post)}
I'm trying to export my whole project through the option ExportPLCopenXML. It seems working, but when I'm trying to import the xml I have the following error during the importation process: Object reference not set to an instance of an object. It seems a usual issue with this process that affects to the pointer to user classes inside a procedure. I receive this error for two general functions that have this pointer declarations in the VAR_INPUT section. It seems a bug into the export/import process of CodeSYS and I couldn't skip it so far. Anyone could help me? Thanks in advance.

Post by madskaizer on ModbusTCP Slave Device, maximum uiClientConnections? ^{CODESYS Forge talk (Post)}
I got a Wago PFC200V2, running Codesys 3.5.16.40, 100ms scan cycle, consumes about 20ms. It will randomly crash the runtime every 10 minutes to a few hours. We suspect an overloaded ModbusTCP Slave Device, as this is work done by a 3rd party contractor, but we can not find anything in the help files or documentation, that mentions a hard limit on maximum number of clients connections. This PLC currently has 44 client connections to the Slave Device and 29 slaves configured for its own Master Device. This topic metnions a hard limit of maximum 16 connections, but where is this written? https://forge.codesys.com/forge/talk/Engineering/thread/bd95b9d6d2/

Post by ameba on PersistentVars and Webvisu Element ^{CODESYS Forge talk (Post)}
hello everyone I would like to try to better understand how persistent variables work. I created some boolean variables in the PersistentVars section initialized to the value TRUE. I have tied these boolean variables to toggle switches placed inside the HMI interface pages. Once the PLC program is started, the lever selectors, if operated, change their state, at least at a graphical level, but the persistent variables do not undergo any variation. Initially the above variables were declared as simple global variables, in this case the operation with the levers was correct; I then tried to transform them into persistent ones with the aim of using them as "settings saver" Thank you for support Bye

Post by dhumphries on Codesys device configuration ^{CODESYS Forge talk (Post)}
First make sure the programming laptop and HMI are both on the same subnet. For example if the IP address of the HMI is 192.168.1.125 with a subnet mask 255.255.255.0 set your laptop IP to 192.168.1.120 with a subnet mask of 255.255.255.0. Make sure the cables are fully connected (the ethernet port on my programming laptop will click once but the cable is not fully seated.) Make sure the HMI is powered on, try pinging the device from a command prompt, if you can't ping the HMI there is a network issue that has to be resolved first.

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 jmohre on External file with relative path ^{CODESYS Forge talk (Post)}
I try to add a simple text file to my PLC application, so that is download everytime the application is downloaded to the target. What I did is to add an external file to the application and this works perfect as long as the external file location does not change. It looks like the external file path is stored absolute in project. But if different users work on the project they may have different locations where for their working directory. Is there an option to store the external file path relative e.g. to the project file? Or does s.o. know a different solution to add a text file to application in order to download automatically with the application? Thanks

Post by idalu on Profinet PN_Controller Issue, Network Adapter ^{CODESYS Forge talk (Post)}
i have a problem with Profinet on my project. I'm using Codesys RTE 3.5.19.50. When i download program to controller the ethernet is ok, PN_Controller is ok but every device i'm trying to connect is red with error "DCP no RealStationName". When i'm trying to Scan for Devices on PN_Controller there are no devices found. I have installed Codesys driver CmpEt1000Drv to my network adapter (i'm sure it is right intel pro 1000 model). I have noticed that when i installed codesys driver i'm no longer able to ping this network adapter (i can ping it when intel driver is installed). On my previous projects with runetimes i can ping it even with codesys driver installed. I have also tried to do downgrade of everything to version 3.5.19.20 and it not helped.

Post by dhumphries on No source code available ^{CODESYS Forge talk (Post)}
Try using an Ethernet/IP scanner instead of an adapter, I'm guessing the 2 devices you're trying to communicate with are adapters, you have to have a scanner somewhere and Codesys should be a scanner. I don't know why you're getting the error, you should be able to use your Ethernet port as an EthernetIP adapter (although I've never had a reason to try,) but it's probably not what you wanted to do, unless you're connecting to another PLC that is a scanner. Good luck configuring the devices you're trying to connect to, it will be a lot easier if you have an .EDS file instead of starting with a generic module, even with an .EDS it can be tricky getting the communication working.

Post by superjojo2002 on Licensing info not available. ^{CODESYS Forge talk (Post)}
If support for a containerized CODESYS runtime with a license isn't feasible, then I've considered an alternative approach: I've purchased and activated a "CODESYS Control Basic S" license on my Windows notebook, where I already have the Codemeter Control Center installed. Upon activation, I can see the CODESYS license as active on my notebook. Subsequently, I followed the instructions provided in this link (https://faq.codesys.com/display/CDSFAQ/How+to%3A+Setup+a+Wibu+Network+Server+Access+for+Licenses) to configure the Wibu runtime in the CODESYS container to access my external license server hosted on my notebook by editing the CODESYSControl_User.cfg file accordingly. However, it's worth noting that I'm still receiving a response from the Licensing Manager indicating that the runtime is persistently searching for a dongle instead of recognizing the soft container. So how can I get my runtime licensed now? Any ideas?

Post by fontrap on cmDongle Raspberry Pi issue ^{CODESYS Forge talk (Post)}
Good morning @eschwellinger, After some research I found out that the problem is the preinstalled CodeMeter on Raspberry Pi. As I mentioned the CodeMeter was installed on the Raspberry because I use a license from other vendor that needs the CodeMeter to be installed. The problem is that when I uninstall the CodeMeter from Raspberry I am able to detect the dongle from CODESYS and everything works as it should be but now the other product can not detect its own license. When I reinstall the CodeMeter I am back to the initial problem. Is there a way to overcome this conflict through CODESYS?
