Is it just me, or is the option to import a configuration file for the add-ons missing in the new version of codesys installer?

Hi eschwellinger, Thanks for replying, but I'm not shure if I got it right. Do you mean that I have bad configuration on my CODESYS config file? Or in my project? Thanks in advance!

Hi francoinf, I've the similar problem and similar configuration. I did with an Arduino Board loaded by a ModbusRTUServer application on it. What I've notice is the slowly acquisition when release the digital signal (e.g. pin2) when it gets off. Anyone have suggestion?! Thanks

I am having the same trouble. However, if I change the Login Configuration settings to 'Type: Login using the credentials determined at runtime' then the Connection information continues as 'Connection state: Connecting' and 'Error information: OK'. There is no User Management on the source PLC.

Scan from "IP-Configuration" with PC connected to first EtherCAT slave and "EtherCAT" tick box ticked gives slave info. As does ticking the "Emergency" tickbox.

Post by manuknecht on Opening a Dialog on a specific Client from ST ^{CODESYS Forge talk (Post)}
I managed to find a solution that seems to work reliably. As the VU.Globals.CurrentClient-filter accesses the CURRENTCLIENTID or at least a similar, internal variable it can only be used if called from a certain client (e.g. from a button in a visualization). My solution works by implementing a new client filter that compares the client ID of all clients to the ID of the last client that was used. The variable containing the data of the last client is defined as: G_LastClient : VU.IVisualizationClient; // Copy of last client that detected click This last client is then updated every time a button is pressed using the Execute ST-Code input configuration of the button: G_LastClient := VU.PublicVariables.Clients.Current; Next, I created a function block that implements the client filter interface as so: FUNCTION_BLOCK FB_LastClientFilter IMPLEMENTS VU.IVisualizationClientFilter VAR_INPUT END_VAR VAR_OUTPUT END_VAR VAR END_VAR Then i added a method to the FB called IsAccepted which is used to filter out the client. When creating the method, it should automatically be filled with the according variable declaration, as it is defined in the interface: (* For every client can be desided, if it is accepted. ``TRUE``: Client is accepted*) METHOD IsAccepted : BOOL VAR_INPUT (* The client, to check*) itfClient : VU.IVisualizationClient; END_VAR Now the client can be compared to the last used client as such: // check if clientID corresponds to clientID of last recorderd client IF itfCLient.ClientId = G_LastClient.ClientId THEN IsAccepted := TRUE; ELSE IsAccepted := FALSE; END_IF To make use of this custom client filter, initialize a variable with the client filter: LastClient : FB_LastClientFilter; // Client filter to find last used client Then use this client filter when opening or closing a dialog from ST: fbOpenMyDialog(itfClientFilter:=LastClient,xExecute:=TRUE,sDialogName:='VIS_MyDialog_DLG');

Post by dogulas on Removing a symbol from the IEC Symbols Editor grid ^{CODESYS Forge talk (Post)}
gatto, That works. Thanks. Typically I use my mouse more than my keyboard. That's why I was looking for a delete option from the right-click context menu or a delete button on a toolbar at the top. It never occured to me to use the keyboard. It might be a little more user friendly if they allowed a mouse wise ability to remove a line from the grid as well as the DEL key. Just a suggestion. Thanks for your help.

Post by alsiddhartha on TextList name error (fake) ^{CODESYS Forge talk (Post)}
Hello, I’m developing a program and for some reason I got this error: C0193: Name '2,Recipe #2GVL' is no valid identifier I was creating a combo box and creating a TextList for my recipe. I couldn't find where the error was, until in the combo box properties in the 'Text List' property in the options it gives me to select, I found '2,Recipe #2' to be able to select (I never created a list with this name) and I can't find a way to delete that option or I can't find where that list is. I tried to delete the TextLists, delete the combo box, to clean the project, but the error still there. How can I delete this option (2,Recipe #2)? Or how can I fix this error?** Thank you.

Post by tehthoams on Library Search not working ^{CODESYS Forge talk (Post)}
Hello All! Having a strange issue. When adding a library, I'm unable to search. Each time a window pops up 'creating the search index' and then has 0 results. I have the same behavior when using the library repository and pressing the 'Find' button. I wonder if there is a way to reset or fix this issue? It is making it very difficult to search and find proper libraries to add to my project. Much appreciated.

Post by carohe on %t SystemTime in Variable ^{CODESYS Forge talk (Post)}
Hello, if you enter %t as a "Text" on a rectangle and do not link a variable in "Text variable", it automatically displays the system time. My question is, where do if find a variable, that contains exactly this time? I tried numerous variants using GetLocalDateTime or GetSysTime but I always have to manage timezones myself (which I do not want to do). I only want a variable with the date an time from my windows system, where the visualization is running. Where can I find this variable?

Post by trprsmn on "Scan Network" doesn't find CR1140 device (ifm) ^{CODESYS Forge talk (Post)}
Hi, I'm watching an ifm tutorial on how to setup an industrial controller in CODESYS. I'm using an 'ecomatDisplay43inch_64bit) controller. CODESYS Gateway and PLC are both runngin (systray). However if I click "Scan Network" I can't find my controller. The only thing it finds is a "desktop" it seems (I'm using a Windows 10 on a Mac Book using VMWare, so maybe it has something to do with that?). How can I fix this? Thanks in advance!

Post by bruno-roth on Read "Homed" status from EtherCAT drive ^{CODESYS Forge talk (Post)}
Hello, the information if your axis is already homed you could only find out direct from your Slave. In DS402 status there is no Bit defined. But some manufacturer of Drives use some optional bits or status. E.g. if you have Schneider Electric LXM32 Servo you will find this information in Bit 15. You have to check the manual of your used Servo-Drive f this information is provided in any object and then read it out with SDO.

Post by pernockham on Engineering IDE from linux? ^{CODESYS Forge talk (Post)}
An update note. Still using linux/Qemu. Still happy, but sometimes some things are harder. I lost the "bridge" connection to my VM (meaning for instance I couldnt "scan network" and find local units. Have spent tons of hours to find out why. Finally it seems the traffic got blocked by the firewall/iptables so needed to set rules for that. So friendly note that rules must allow forward traffic to/from you configured host bridge device.

Post by sturmghost on Find visualization elements that require a lot of computing time ^{CODESYS Forge talk (Post)}
I found out that the Codesys simulation mode is not good to measure performance. As soon as I upload the code onto the hardware PLC I can see that my visu-task needs around 60 ms to complete. I'm wondering if there is a possibility to find out which visualization/visualization element takes a lot of computing time? Then I would look for ways to decrease the long computing time.

Post by rpostwvu on Shared Memory Access Issues ^{CODESYS Forge talk (Post)}
I got the shared memory example. I'm pretty sure I'm successfully created a memory space, CreateResult returns 18. szName:='CodesysDataShare'; hShm := SysSharedMemoryCreate(szName, 0, ADR(uxiSize), ADR(CreateResult)); I'm trying to access this memory with a C# application, but I get "Unable to Find Specified File". I suspect that Codesys and/or Visual Studio code alters the name I choose? Being in Windows, I cant find a way to see the mapped memory list. ~~~ using (var mmfRead = MemoryMappedFile.OpenExisting("CodesysDataShare",MemoryMappedFileRights.ReadWrite)) ~~~
