Post by otdeveloper on IEC 61499 ^{CODESYS Forge talk (Post)}
It is being worked on by many companies and its even-driven function blocks seem like a natural evolution of the object oriented industrial programming I have seen Gary Pratt (author of the Book of CODESYS and much more) so expertly implement and explain. I would expect CODESYS to have this front and center on their sights and, if they do not, I would be very interested in learning why.

IEC 61499 is probably something more complex than what you have correctly said so the prospects are interesting but we cannot ignore that it came out almost 20 years ago and has not won many hearts. I started to explore this world with a PLCnext controller because I love these devices based on RT Linux and Codesys is somehow usable with them but I have made little progress and I feel like inside a nutshell in the middle of the sea ;-) Gary's voluminous and precious book is always on my desk...

Post by nmcc on Toggling Visualizations using HMI Physical Buttons ^{CODESYS Forge talk (Post)}
Hey thank you for the reply dkugler. I am sorry if this seems like a stupid question. I have the use current visuvariable checkbox enabled. I can see the string names of all my visualizations. I am trying to use ladder logic to be the anser to the button press using "VisuElems.CurrentVisu := 'MainScreen';. This returns an error. Any idea what I am doing wrong or could you point me in the right direction for fixing this. Thanks,

Post by mondinmr on Direct Pointers in IOMapping for EtherCAT with IoDrvEthercatLib.ETCSlave_Dia ^{CODESYS Forge talk (Post)}
I have found a very interesting solution using: IoConfigTaskMap IoConfigConnectorMap IoConfigChannelMap The first is the list of IO tasks. The second is the connector for each IO module in the IOMap. The third is the individual input or output on the IOMap. One of the properties of the connector is another pointer to a connector, which corresponds with the connector of the EtherCAT slave. Through this information, it is possible to understand to which EtherCAT slave an IO connectormap corresponds. I am attaching an FB that allows for the construction of an IO map and finding the pointer to the actual IOs in the IOMap based on the bitoffset.

Post by kleeswi on SysFileOpen does not work after update to V3.5 SP19 Patch 5 ^{CODESYS Forge talk (Post)}
I use the function SysFile.SysFileOpen(sFileNamePara, SysFile.ACCESS_MODE.AM_WRITE, pErrorFileOpen); to open and write a file. Since the update from Codesys V3.5 SP17 to V3.5 SP19 Patch 5 it does not work anymore. I first had SysFile.SysFileOpen(sFileNamePara, SysFile.ACCESS_MODE.AM_APPEND_PLUS, pErrorFileOpen); in both versions. hFile_Test is a pointer to byte. It gives an exceptional error when dereferencing the hFile_Test pointer. Edit: I use Codesys on a Raspberry pi

Post by timl on BacNet Server ^{CODESYS Forge talk (Post)}
Hallo, für einen BacNet2 Server lassen sich mit zwei Ethernet Schnittstellen auch zwei Bacnet 2 IP Datalinks anlegen. Einen Datalink nutze ich für den UDP Port 47808 und einen für den UDP Port 47809. Dadurch ist der Server aus beiden Netzwerken erreichbar, was so gewollt ist. Allerdings verbindet er die beiden Netze auch miteinander, was zu Kommunikationsproblemen führt, da in beiden Netzwerken bereits gleiche Device ID's vergeben sind und diese sich dann doppeln. Lässt sich diese Verbindung der beiden Netze abschalten? Gruß Tim

Post by martincapd on EWON ^{CODESYS Forge talk (Post)}
I have the same problem in that I can connect to the eWon and ping the controller IP Address, however I cant connect through CodeSys. I'm using Gateway-1 which is configured to use "IP-Address: localhost" and "Port: 1217". Rather than scanning the network for devices, I enter the IP Address of the device, codesys returns a "No Device is repsonding..." message. See attached. I'm wondering if the IP-Address used Gateway-1 should be "localhost" or the WAN/LAN IP of the eWon? Thanks for the help MC

Guten Tag, zuersteinmal vielen Dank fürs Lesen! Ich habe das Problem nun lösen können, indem ich %appdata%\CODESYS\UserOptions-EEEF5821 gelöscht habe. Dort gab es diverse Dateien names "CODESYS (CODESYS V3.5 SP17).opt.*". Nun funktioniert das Menü wieder so, wie es soll. Was ich mir sonst zerschossen habe, werde ich herausfinden. Aber ich denke, außer ein paar Einstellungen kann nicht viel passiert sein. Da ich das Gerät aber sowieso erst neu bekommen habe, ist hier noch nicht viel passiert. In diesem Sinne vielen Dank für die Aufmerksamkeit und ein schönes Wochenende Frank

Hello everybody, I'm trying to understand the SL control extension package, more specifically, the external IODriver example, because C integration is very easy and I just made my first C component successfully. Ther External IODriver has no documentation and it's not clear how to proceed. Furthermore, there is no information on how to modify the device descriptor, which is necessary to import the device into the Codesys repository. Any advice ? Thank you in advance and best regards.

Post by andrej on POU - Access to runtime ^{CODESYS Forge talk (Post)}
Hello all, when creating a POU, the Codesys IDE allows the setting "Enable System Call" (in the Settings, Property -> Build), see picture. The name suggest, that runtime functionalities i.e. functions of codesyscontrol such as "stop plc" etc. can be directly called. I tried various approches without success, the following does, unsurprisingly not work. FUNCTION accessRTE: BOOL; ****************************** codesyscontrol.stop(); Can you please tell me how I can make a system call to codesyscontrol from a POU. Or could you provide me with a use case for this setting. Many thanks for your feedback and kind regards Andrej

(dhumphries) I followed your advice and tried it on Ubuntu Server. Was a good choice. Your material was also very helpful :). Thanks for Your help! I no longer have problems connecting to Ubuntu. However, I still cannot install Virtual PLC. I'm currently getting a missing path message: "C:\Program Files\CODESYS 3.5.19.60\CODESYS\CODESYS Virtual Control for Linux SL\Delivery\virtuallinux\VirtualControlAPI.py." It looks as the package: "CODESYS Virtual Control for Linux SL" was not installed. But, there isn't one in CODESYS Store or I'm doing something incorrectly.

Post by timvh on IFM CR711S Version Mismatch ^{CODESYS Forge talk (Post)}
You should ask IFM to provide you with the correct version of their controller packages. Then after you have installed this, you can select the correct version of the controller by right clicking on it in the device tree, update device, enable the option "Display all versions" and then select the version which matches your controller. Alternatively you can ask IFM to provide an update package which can update the runtime version on your controller to 3.2.0.0.

Post by miodusy on File transfer via visu and codesys automation server ^{CODESYS Forge talk (Post)}
I have a problem with the file transfer library. Namely, it does not work via the codesys server. (error 5; overtime, and visualization resets). They operate mostly in local chains. I tested different browsers and VPN from the router. It works everywhere, except through access from the codesys automation server. The client, having many machines under one account, prefers to keep it that way rather than use an individual VPN just to download a backup. Does anyone have an idea what the problem is? Sylwester M.

I had similar assertion failed error messages today. I am fairly new to Codesys. I tried using SFC for the first time, I usually use ST. Anyway I had errors in some of my transitions. I copied and pasted transition code and forgot to change the target of the code. I started getting lots of the assertion errors but now I have sorted out the problems and it compiles OK the assertion error messages seem to have stopped. There do not seem to be any other responses to your post, did you resolve your problem?

Hello Matteo, I think the problem is about configuration of firewall (windows firewall usually). You can disable temporary the firewall to check if the communication works. Eventually you can: Go to the control panel -> Windows Defender Firewall -> Allow an app or feature Enable the options to change the settings. Scroll down in the application list to CODESYS and CODESYS ControlService. If you don’t see this application add it to the list. Make sure that all the checkboxes are checked (Domain, Private and public).

Hello @rmaas I assume, you've already verified and tuned everything regarding the EtherCAT network. In my case the problem was due to a wrong core assignement. I suggest to not use the core #0 for your EtherCAT task. The OS realtime patch, which is present on RevPi OS, uses the core #0 for its porpouses and it mustn't be used by any other task which requires realtime and deterministic features. regards Rossano
