II have a constant error in my PLC logs that just keeps repeating endlessly but there doesn't seem to be anything wrong and all of my network devices are green and communicating properly. Does anyone know how I can find the cause of this and stop it? It is clogging up my logs and making them useless ffor troubleshooting.
I ran Static Analysis on a project. But ever since then it won't let me compile the project unless my license dongle is inserted. How can fix my project so that I can compile it with out the license again? I also get a build error saying the following. But there are no error listed in the Additional code checks catagory. If I insert my dongle and restart codesys. Then I can compile with no error ------ Build started: Application: Device.Sim.Device.Application_Test_ ------- Typify code... [ERROR]...
Question: Are you expecting a separate instance of the Function Block for each client that connect to the WebVisu server? If yes then it is a little more complicated if no... The best way, I have found to handle things, is to have a Function Block defined for each Visualization you have defined. this function Block serves as the "View Model" So like the Main Visualization has a viewModel and it is a reference to an instance in the process code. Because it is in the process code FB_init is called....
The impression I got from them was that everything on that list had been asked for by other users long ago (Except for function pointers/delegates). They said they were on their "back log" list. So I assume they will never happen.
Thanks I knew I had seen it some where.
If you indeed want 3 identical instances that is in my opinion the proper way to it. That is how I do it. If you think it is messy I would advise you work on splitting up your program structure in to organized units. A flat data model will always be messy.
I assume like my experience, Codesys threw and error during installation and didn't finish. Are you running the latest installer or are you trying to install with the original installer for that version? Try closing everything codesys related including the gateway and WinControl Target and do a repair install.
Yeah I have had terrible luck with Codesys NA, they always seem like the just want me to go way and leave them alone. They give a lot of canned responses and make me feel like I am talking to a wall. Also the only "help" they will do for free is send you a link to the documentation page. Documentation pages which you have already read thoughtly, and are very vague and missing alot of context. If you want anything more than that you have to pay them by the hour. Even if you submit a ticket it can...

It might be possible, Try asking on http://www.plctalk.net/ There are experienced engineers that deal with Rockwell and Codesys on there. If you do get a solution please post it back here for others.

My question was mainly rhetorical. What if you want to Open Dialogs from the VisuTask and not make a mess trying dealing with an asynchronous FB call? You can't using the VisuUtils library. That was my point. The common behavior model doesn't always fit well with OOP design. It shouldn't be a one size fits all solution. I am trying to build a UI framework library and I need to call dialogs directly from the VisuTask. If they also provided a syncronous call API in VisuUtils that would be fine, but...
Dumb Question: but why do you want to received email on a PLC? I assume you want the PLC to act as an Email Client (Not a server)
To my knowledge you can't modify a text list at run time. (but I am not 100% sure) You might want to create an array instead for the combo box to you. If you need multi-Language support on your combo box there are ways to do that at run time, but it is going to get tricky. I haven't done that yet though. I have only read about it. Sorry I can't be more help.
I just had this issue, and VISU_USEPROPERTYINFO was already defined. So I unchecked "property handling in visualization element" pushed apply, then rechecked "property handling in visualization element" and pushed apply. Then recompiled. That fixed the problem.
Why is IDialogManager.OpenDialog Obsoleted? It says to use VisuUtils but VisuUtils is an incomplete interface as it is designed to be called continuously and not be called from the Visu_Task. Am I missing something or is Codesys intentionally removing capabilities?
I want to get the name of the current task (As a string) that is executing a block of code? What is the easiest way of doing this? I have tried looking though the help documents but I am not finding what I am looking for.

Wait I found it.

Where is it writing to if I put C:\ on it? it says it is suceeding.

Is there any way to extend Codesys Development System with C# or Python to add your own refactoring functions? I would very much like to automate FB properties to automatically add a backing VAR. It is vary tedious doing that by hand.
I have extended it, I have 2 derived types. But I want the to have the Reference point to either of the derived types. Since it is only a Reference it seems to me it should work.

3.5.18.2 Wago PFC 100 I just bought the Pro Edition, because I have some serious performance issues in my code and cycles are taking along time. like 75ms. So I added the profiler to my project, I selected Instrument whole application. I selected the main task, and I set the Condition to a Boolean tag. When I download and go on line I am greeted with a dialog message that just says "No records". I run the program. and enabled the boolean, but nothing shows in the profiler tab. What am I missing?...

So if your FB implements say InterfaceA and you set your Input as type InterfaceA it will pass by reference? I hope this may shed light on your question. PS offcourse passing by reference is much wiser when using i.e. FB's structs, array's or strings. I honestly not really because as you point out, it IS usually wiser to pass them by reference. but I guess IEC saying so makes sense why codesys does it this way, but not why IEC 61131-3 says to do it this way.

{attribute 'no_assign'} is a good tip I mean, needing to pass by value is so rare, you could just build you own Clone Method, where you pass, the instance and then copy it member my member to a different instance. this is the norm in C#

Being pretty experience with C# I find this to be baffling. IN C# All Objects are passed by reference, but structures are not. In what cases would would want to pass a function block by value? I have never found myself wanting to do this. Now Structs sure I can see wanting to pass those by value, and that is also how they behave in C#. Can anyone shed some light on the rational for this behavior?

Trying to connect to a EIP remote IO device and I am getting the following error messing on the status page of the device. I have tried googling it and I have found nothing.

Well what I am trying to do is to return a Reference to EngValueBase but using type IEngineeringValue so that the consumer doesn't care what the base class is. I plan to have different implementations of the EngValue later on which is why I want it to be behind an interface. I have tried using := instead of Ref= but I get a run time exception, of access violation.
I think you are incorrectly assuming what IEngneeringValue contains. Right now it has it's own Properties of Value and MeaUnitAsString. The intend is to have a mechanism in place so that different types of engineering values can be compared if they are of the same type, Like Temperature, could be compared if if one instance is of using Celsius and one instance using Fahrenheit etc. Further set points in the system will be stored in the same mechanism. So I have a very valid reason for want to but...

Ok so I switch my device from a PFC200 to my Control Win x64 and now I have resolved that issue. I have a new issue which I started a new thread about. https://forge.codesys.com/forge/talk/Engineering/thread/9008bd0c33/
I am getting a connection error with my Wago 750-363 The log shows a Invalid O->T size. (16#127) I've never tried to connect to a Ethernet/IP Adapter from Codesys. So I am not really sure what the procedure usally is for setting these up. Here is my configured Assemblies in codesys And here is what the 750-363 Web Config says is on the Adapter/Coupler
oooooh, All that is available right now is my Control Win x64 runtime on my laptop. I don't have a PFC200 yet, I do have a 750-363. I was trying to configure my project and do some tinkering before I actually buy a PFC200. So do I need to have Codesys Engneering connected to a PFC200 to continue the configuration?
I downloaded the PFC200 runtime target. I am trying to configure my EtherNet/IP Scanner to connect to a 750-363 fieldbus coupler. However whenever I try to select a network interface to use I get the following error "Gateway not configured properly". I've tried googling it but I can't find any information on this issue. See attached screen shot.
