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

It seems that the hmi sl license only works with windows. If i'm happy using web visu, rather than target visu, is possible to use remote opc-ua remote alarms without the hmi sl? Maybe it can be included in a different license that works on Linux? thanks

Post by totorovic on CSVReaderInit returns error : INVALID_HANDLE ^{CODESYS Forge talk (Post)}
We changed the path where the CSV file is. From intern memory of the IPC to a USB key. We still have this error 'INVALID_HANDLE'. We must restart the Codesys runtime to clear it. That is a big problem for us because machine is in production. @eschwellinger What do you mean by "this is a security issue not to read/write in the plc allowed path"

Post by bjarne-pagaard on WebVisu with Runtime Based User Management, Default user (no login) - is it possible? ^{CODESYS Forge talk (Post)}
Hi, With the new Runtime Based User Management, is there any way for WebVisu clients to be logged in to a default user automatically - no login prompt? I would like for the default user to be able to perform normal operation of the machine, without logging in to the WebVisu. This is possible with the Legacy User Management. For the Runtime based user management, there seems to be a default user for the TargetVisu - but not for the WebVisu. -Bjarne

Post by kreisfilho on Stop raspberry from executing a plc program ^{CODESYS Forge talk (Post)}
Hi guys, Can someone inform where in a raspberry pi are stored the codesys programs? I´ve been training the use of a RPI as PLC, which works pretty well, however while both the RPI and PC (running codesys) remain connected to the same network. The question is: how to run the codesys program downloaded to the RPI as a stand alone device (disconnected from the PC)? Thanks! Kreis

Post by aott33 on Webvisu NO load ^{CODESYS Forge talk (Post)}
Thanks, I will check the PLC Log when the PLC is connected again. I will update my findings here. Since I don't have access to the Linux Panel PC at the moment, I tested inside my development VM with the same Linux OS. I have no issues or delays connecting to the WebVisu using my Linux VM. Two main differences: 1. My host Computer has a faster processor compared to the panel PC. 2. There are no devices connected in my dev environment. I will continue testing when I have connection to the panel PC.

Post by hafizapik99 on Webvisu not showing Codesys V3.5 SP13 Patch 4 ^{CODESYS Forge talk (Post)}
Hello, I am using a Hitachi Micro EHV+ for a small project, and I wanted to have a Web visu, done with Codesys V3.5 SP13 Patch 2. I test the Visu screen and it works well in Codesys, but I get a blank page when i enter the web visu in a browser. Here is the setting under web visualization: Update rate (ms): 5000 (previously set to 2500 also not working) Default communication size: 100000 (previously set to 50000 also not working) Under Visu_Task tab: Priority: 3 The Visu_Task interval is set to 2500ms (previously set to 200ms also not working) I'm using Google chrome with the latest update, the Javascript is enabled with HTML5. Any advice?

Post by timvh on Current Visu name without Current Visu Variable ^{CODESYS Forge talk (Post)}
To change the current visualization for (all) webclients: Add the library “Visu Utils” and use the following example code: VAR xChangeVisu: BOOL; fbChangeVisu : VU.FbChangeVisu; END_VAR // Change to Visu2 when setting xChangeVisu to TRUE fbChangeVisu( xExecute:= xChangeVisu, xDone=> , xBusy=> , xError=> , itfClientFilter:= VU.Globals.OnlyWebVisu, //itfFilter, eError=> , sVisuName:= 'Visu2'); IF fbChangeVisu.xDone OR fbChangeVisu.xError THEN xChangeVisu := FALSE; END_IF

Post by manuknecht on Specify Input Configuration "OnDialogClosed" Action to only react to certain Dialogs ^{CODESYS Forge talk (Post)}
I have a project with several buttons and dialogs. Most of the dialogs are opened using the Open Dialog action of the Input configuration of the buttons. Some dialogs are openend using the FbOpenDialogExtended FB of the Visu Utils library and the FbOpenDialogExtended FB is called in the Execute ST-Code action. I am also using the FileOpenSave dialog from Visu Dialogs which requires an OnDialogClosed action to read out. I realized that the OnDialogClosed action which is meant for the FileOpenSave dialog also triggers if a dialog is closed, which was previously openend using the FbOpenDialogExtended FB. Is there a way to detect which dialog was closed last and specify to which dialogs the OnDialogClosed action reacts?

I will use Codesys to program a PLC. I will connect the PLC to the computer via the CAN interface using PEAK CAN, but Codesys does not recognize the CAN adapter. I have added the following libraries. What should I do? What steps should I follow?

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.

Post by rickj on Defining local variables that can be independent with several users. ^{CODESYS Forge talk (Post)}
You need to create an array with one element for each possible user. I usually define these arrays in the root screen. FrameIndex : Array [0..MaxUsers] OF INT; Then use the global CurrentClientId (defined by one of the VISU libraries) to index the array element used to select the frame. FrameIndex[CurrentClientId]

Post by durallymax on Access Variable Visu Dialog ^{CODESYS Forge talk (Post)}
Is there a way to access the variable in the called dialog? Example: Text Field element with PLC_PRG.myVar as Text variable. OnMouseClick configured to write variable with keypad pop-up. OnValueChanged configured to Execute ST RND(PLC_PRG.myVar,2); Rather than change myVar with each copy of this Text Field, is there a way to access whatever the configured text variable is? Generally try to stay away from ST in visu, but was curious regardless.

Post by sanacfu on looking for v2.3 libraries on v3.5.19 ^{CODESYS Forge talk (Post)}
Hi all, I'm new to Codesys and Wago but well versed in Rockwell. I've been tasked with upgrading old Wago 750-880 PLCs that run Codesys v2.3. All I was giving is the original PLC program in v2.3 and the currently running machine. I've spec out to what I believe is a suitable upgrade, the PFC100 2ndGen, 750-8111. As I'm rewriting this code on the Codesys I can't find the same library functions blocks for ethernet settings PLC functions. Currently I'm working on code to get/set the PLC ethernet IP address and HMI IP addresses from the HMI screen. One other function I'm looking for is a warm reset function to the PLC. When googling for this stuff I see a lot of code not in ladder logic. Are these functions now not available to implement in ladder logic? Where can I get more information on finding and implementing this functions? Do I have to buy a license from Codesys to use these functions? The PLC I ordered should be arriving in 2-3 weeks.
