Why do you develop things like this? The workflow should be highly dependent on autocomplete, then if that's not super obvious browse to definition and everything is made clear possibly with the checking of a few types. The nature of how things are done makes me think these libraries aren't developed for general use and are actually internal or for partners. The example projects include objects that don't appear in autocomplete and then lead nowhere obvious when browsing. Do you consider developer workflow when creating these libraries? Are some libraries really for public use such as Visu Utils and others not? If so which? It's really hard to tell.

Post by trusty-squire on parker servo and position ^{CODESYS Forge talk (Post)}
@gepert, When you say "I do not turn off power", are you saying you don't power off the drive, or you don't turn of the MC_POWER function block? I read your statement as you don't kill actual electrical power. MC_POWER should stay enabled. @Gustavo, not related to problem at all, but when you say 1.6 Nm is only enough torque to unscrew a loose bottle cap, I think that's a bit low. A quick mental math I use is 1 Nm is almost the same force as 1kG applied to a 10cm wrench. So 1.6kG applied to a 10cm wrench is still not a huge force, but more than enough to be felt if trying to turn the shaft by hand.

Post by alimans on OPC-UA Server, Symbol Set: Raise an error: Object reference not set to an instance of an object. ^{CODESYS Forge talk (Post)}
Hi everyone, I just created a very simple library without any code and, added it to my very simple project. after adding this library, I get an error when I try to open "Symbol Set" in "OPC UA Server" in "Communication Manager". Here is the code of my POU in the library: FUNCTION_BLOCK POU VAR eCommand : (CMD_NONE:=0, CMD_RESET:=-1) INT := CMD_NONE; END_VAR Attached is the error that I get. I also noticed that by removing the enumeration variable above (eCommand), I can open the "Symbol Set" again. Anybody has any idea why this error is raised and how could I use enumeration variables without error in "OPC UA Symbol Set"?

Post by gilbertamine on Comparing Arrays of structure ^{CODESYS Forge talk (Post)}
Hi Everybody, I'm looking for a simple way of comparing two array of a structure. My structure is define like this : TYPE Positions_T : STRUCT PosX: DINT; PosY: DINT; PosZ: DINT; END_STRUCT END_TYPE I have multiples Var : ARRAY [0..220] OF Positions_T, that I need to compare quickly. I don't really want to do a Loop that goes by every 220 points and compare each one of them so I was wondering if there is another way. I came accross the MEM.Compare function, but it require to know the size in Bytes of the memory, and I don't know how to do that... Has anybody an idea on how to do the comparing easily ? Thanks in advance

Hi all, I am attempting to use the Control Win V3 soft PLC to control a WAGO 750-315 remote I/O system via modbus RTU communication. I am struggling to connect to the device. I have been following this tutorial: https://www.youtube.com/watch?v=YlRfkESaNds I have setup my devices as shown in the images below. I have verified that my com port settings are correct as I am able to connect/control using modbus simulator software with these settings. I have also connected to a modbus master simulator program as instructed in the video, but the orange triangles will not go away. Additionally, I have updated my settings to 485 using the PLC shell. I have also set "always update variables" to enabled (1). Serial port, PCI-Bus, and modbus serial device status all show as "Not Running."

Post by jonathan1321351 on IO-Link write parameters Ethernet/IP ^{CODESYS Forge talk (Post)}
I want to read and write parameters of an IO-Link device using acyclic messages. I have a Cube67+ in Ethernet/IP, connected to an IO-Link master. In the datasheet, I can find the parameters required for the message (Service, Class, Instance, etc.). I see the function block "Set_attribute_single" in the "EthernetIP Services" library, but I'm not sure how to correctly send the index and sub-index for the IO-Link device. The class in the datasheet is 0x80 for the IO-Link Parameter Object, but it’s not present in the CPIClass enum. Is there another function block more suitable for configuring IO-Link devices? (similar to "iol_call" in PROFINET or what’s used in EtherCAT).

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 opineiro on Stack overflow with really simple function ^{CODESYS Forge talk (Post)}
Hi, I have an issue with a function which sends a message through API Rest. I'm using a function from httpCLient library. I have tested this function inside a program and it works fine. But when I want to use it inside a function (so I can call it simultaneously from 2 different points on the main program) it gives a stack overflow error. In detail it says: "C0297 Stack Overflow on Main Task. Stack sizes... Call hierarchy:" I have simplified as much as I can the function, but I'm hitting a wall with this. Anybody has an idea of what's wrong? Thanks!

Post by opineiro on How to manage variable types larger than 64 bits - Ethernet/IP ^{CODESYS Forge talk (Post)}
Hi there, I have a Keyence bar code reader connected to my plc through Ethernet/IP. The Bar code is 20 digits long (like 30100790020493036016), the scanner reads it correctly (I can verify that through the keyence software) but when it sends it through ETH/IP, it doesn't fit into a 64 bit variable and it trunks the data.(I've tried ULINT and LWord without success). When I loaded the EDS file, the read variable was defined as a byte with 128 bits length, which is quite strange for me. (see attached picture) How do I manage this variable? Thanks!

Post by davidbo on RPI can system operation like rm in a shell have an impact on a Task cycle time ^{CODESYS Forge talk (Post)}
I have noticed that a rm file1.txt command on a shell has an impact on the cycle time for a TASK writing to file2.txt. Seen in the Monitor fane of the Task configuration Furthermore if a TASK makes a system call like rm, its cycle time increases of course but it seems to have an invisible impact on other TASKs too. I have a TASK for handling communication over the CANbus (SPI) where it stops sending "Heartbeats" for many seconds when another TASK does a system rm. Why is that not seen on the Monitor fane? Is even codesyscontrol paused when system calls are made? The CPU load is about 30-40%

Post by andrebrandt on FB string and naming ^{CODESYS Forge talk (Post)}
Hi Tim. Not quite correct. What i'd like, is when you place the FB in prog, i choose a block NTC10k, and name this RT401. What i'm trying to do, is to get the name RT401 automaticly into the FB, so i can put this into the string i pass in a struct. So in var in POU, i saw this a place i could do this, RT401: NTC10k(Tag:='RT401'), but i can't get this to work. I shurly must have had something like this in FB: FUNCTION_BLOCK NTC10k String TAG But it's here where I'm stuck...

Needed to connect to PFC200 via Putty, and open CodesysControl.cfg with “sudo nano /etc/CODESYSControl.cfg”. Then adding following command to the end of file, and use the name you want, save/close CODESYSControl.cfg, and reboot your PLC. [CmpOPCUAProviderIecVarAccess] CustomNodeName= PFC200 Hi! , I'm digging up this issue cause we have still this long name within current versions on CodesysControl. Is it a lock for "demo" licences or can it be changed in some way ? This DeviceSet name is too way long with spaces inside, not easy to handle with string parsing... Cheers !

Post by dakmueller on Digital Input nachrüsten ohne Variablen umbenennen. ^{CODESYS Forge talk (Post)}
Hallo zusammen, ich habe ein Problem mit einer Anlage. Dort müsste eine Digital Input Karte(XNE-8DI-24VDC-P) nachgerüstet werden. Das Problem ist, dass wenn ich die Karte über die Steuerungkonfiguration einbinde, die Karte direkt hinter den Eingangskarten und vor den Analogkarten positioniert wird. Dadurch müsste ich die Variablen der Analogkarten ändern, die hinter der Digitalen Eingangskarten sind. Das wäre Mega Aufwand. Gibt es eine andere Möglichkeit? z.B hinter die Analogkarten zu Adressieren? Z.Zt. sieht es so aus: %IB0 %IB1 %IW2 %IW4 %IW6 Zwischen %IB1 und %IW2 soll die neue Karte. Dadurch wird %IW2 zu %IW4. Dadurch müssen alle Variablen nach %IW2 geändert werden. Vielleicht kann mir jemand helfen. Danke Dennis

Post by siscu on Raspberry i2c master device ^{CODESYS Forge talk (Post)}
I want to implement an extended I2C master for Raspberry Pi Control. I was hoping for it to be as easy as creating a library with a FB that extends i2cMaster and associating it with a device following the forge drivers documentation, but I haven't managed to make it work as the driver behaves only as an i2c slave. I'm thinking this is because the forge forum only talks about extending i2c, and the master portion is omitted since most users won't want to add a custom one. I'd like to know if I'm doing something wrong. Is it really possible to make an I2C master extension device? If so, are there public examples we can check out? Any info on this topic will be appreciated.

Hi everyone, I need some help with displaying an image (test.png) on my device. Initially, showing the image is straightforward. However, I want to be able to update the image dynamically. My goal is to send updated files via FTP to the device, and have the display automatically show the latest version of the image. All images will be sent with the same name (e.g., test.png). Currently, I can see the updated image after sending it via FTP and performing a warm restart, but I'd like to achieve this in runtime, without having to restart the display or application. Does anyone have suggestions on how to implement this? Thanks in advance!

Post by trent on Automation server - trends stop recording - need to manually reconnect ^{CODESYS Forge talk (Post)}
Hi All, I use the analysis page in automation server to capture historical trends from my PLC - i only sample one point per hour but it does the job (for now) One issue I have is I often log on to analysis page to find the system has stopped recording trends from my PLC. To fix this, I need to choose "state information" in the "List view" under PLC and click "Reconnect" When I do this I see my variables listed under "parameters" under "PLC Details" start updating again and the trend in Data analyzer continues to update. My Question, Why do I need to manually reconnect? Is there a way to get automation server to automatically reconnect to the PLC so I continue to capture data from the PLC? Regards, Trent
