Post by timvh on Management of a PLC network from a remote station ^{CODESYS Forge talk (Post)}
Maybe the CODESYS HMI is a good solution. https://store.codesys.com/en/codesys-hmi-sl-bundle.html Run this on the remote main control station. In the HMI application you can add the data source manager and to this manager you can add Data sources. A data source has a reference to the PLC you want to connect to and can get access to the variables of the PLC application. You can then use these variables in the visualization of the HMI application.

Post by mmoncada on Dinamically loading recipes ^{CODESYS Forge talk (Post)}
I'm having trouble with the initial loading of recipes. I can create them and load one or the other, but when the program restarts the recipes are not listed. I'm calling: RecipeManCommands.ReloadRecipes and then RecipeManCommands.GetRecipeCount which returns 0 recipes. None of the methods returns error and if i call them again after RecipeManCommands.CreateRecipe RecipeManCommands.ReadAndSaveRecipe getRecipeCount returns the number of recipes created. When i restart the system, once again they are not listed even though the recipe files are there. Any ideas? Martin Btw, Codesys 3.5 SP 16 Path 9

Post by joep on overruling kinematic limits of [-90°, 90°] in bipod_rotary ^{CODESYS Forge talk (Post)}
Hi All, for my robotics application we are building a 2-axis parallel scara using the kin_bipod_rotary kinematics. Codesys implemented limits of [-90°, 90°] according to the documentation: https://content.helpme-codesys.com/en/libs/SM3_Transformation/Current/SM3_Transformation/Function-Blocks/Positioning-Kinematics/Parallel-Systems/Kin_Bipod_Rotary.html Would it be possible to overrule these limits somehow, our mechanical limits are more in the range of [-110°, 135°] In this range we also don't encounter point where singularity is an issue. Hopeful someone knows a solution, Best regards, Joep

Post by trusty-squire on Display Units/Scale on Path3D visualization ^{CODESYS Forge talk (Post)}
Hi, Is it possible to display the units along the X,Y axis of the Path3D element? It correctly shows the CNC path to be followed, but there's no indication of scale or size of what's being displayed. I looked at the documentation and my first inclination is that this is not possible, and the option option would be to somehow recreate the Path3D functionality into the XY Chart visu element - which is not ideal. Any suggestions or pointers would be appreciated!

Post by pernockham on Inheritence of struct, ^{CODESYS Forge talk (Post)}
Interesting, thanks! Didnt know about ANY before, and will sure find a use-case for it. Im not sure it will help me here though, it seems to me that an ANY will not accept a string assignment? I actually think that the "ALIAS" should work, that was a hard found error. I had a fair bit of scratching my head looking for misdirected pointers before I understood what was (not) happening. I will use the work-around of individual structs instead.

Post by hismoon on Inheritence of struct, ^{CODESYS Forge talk (Post)}
Using a UNION instead of a STRUCT alone should give you that flexibility and only occupy memory once. And if you want to be really elegant, you could use an FB, which only holds PUBLIC VAR. Because a POU can use "EXTENDS"/inheritance. In CODESYS V3, an FB has a lot in common with C++ classes. Using ANY or ALIAS is rarely a good idea. It neither won't be pretty, nor have good readability and requires you to create a lot of error-prone things around it.

Post by atone on Set DeviceID of an IO-Link Sensor at Runtime ^{CODESYS Forge talk (Post)}
I need to be able to change (set) the DeviceID of an IO-Link sensor (see DeviceID.png) at runtime. I tried with both ProfinetCommon.PN_PortConfiguration and ProfinetCommon.IOL_PortConfiguration, but I get an error for both when I try to read the port configuration (see PN_PortConfiguration.png). Does one of those FBs is the right one for my purpose? Do I possibly make a mistake when assigning the parameter IOLD_ID/IOLM_ID?

Post by installwhat on Ethercat and profinet on together ^{CODESYS Forge talk (Post)}
I'm curious about the impact of having profinet and Ethercat (specifically softmotion so frame at start of task?) running together. Since it's advised to access the data from the bus task should have both profinet io and ethercat on the same task? Are there any implications around this one should be aware of especially since the frame at task start is just, so far as I'm aware, an ethercat thing? Thanks

Post by gabrielarffa on Modbus TCP/IP having problems with global variables ^{CODESYS Forge talk (Post)}
I'm using Modbus TCP/IP to communicate Codesys with Elipse E3 as the master for a college project. I have made a list of global variables to organize the programming in two different POUs. The problem is, when I try to do the mapping of variables, the program informs me of an error due to the identifiers having a "." on their names. Do I have to reorganize my code to make it an unified block or is there a way to declare their names without changing all the code structure?

Hello everyone. I have a problem: I installed new version of codesys IDE. When I try open project in this new version, I have many errors about Visu: rectalnge/button/frame/etc does not exist. How update properly project? 20+ pages of visu pages from 100+ frames and all visu elems looks like "Error image". It is not problem of SP20->SP21. Any update has problems from visu side.

Post by sandro66 on Application-based license Modbus Channels ^{CODESYS Forge talk (Post)}
Hi Gatto, Using version 3.5.21.xx, it is no longer possible to use Modbus function blocks (I make extensive use of these FBs.)as shown in the example. https://content.helpme-codesys.com/en/CODESYS%20Examples/_ex_modbus_example.html The compiler detects one Modbus instance for each instance of the communication FB block. The example program above, although simple, reports 8 Modbus instances when compiled with the latest version. Codesys Support says that you must use fieldbus I/O mapping, but this will result in the loss of the ability to programmatically modify communication parameters. Sandro

Hi, I'm having some trouble with an OPC client connecting to the PLC. It could be that the problem is on the client side of things. The PLC have UPS power, but the switch and OPC client does not. It could explain some of the log messages. Could any of you help debugging by the log messages in the attachment? And if possible point me to the right library that explains the different messages? Thanks for all the help.

Is there someone who knows how big of a effort it would be to update Stefan's original code to make it work with a more up to date version of codesys or should i downgrade my system? andrax - are you using a downgraded version of codesys or have you downgraded all the libraries?

Anyone else using the SEND_RECV_MSG function block for RS-485 communication on Schneider Machine Expert? I have had ongoing issues with it for several years, which Schneider tech support is aware of, but hasn't been able to fix. The latest version of Machine Expert (v2.2) appears to have broken some of the functionality altogether. I'd be interested in hearing from anyone else using this platform for serial communication.

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.

Post by martinla on New Codesys Library Dependencies ^{CODESYS Forge talk (Post)}
When creating a new Codesys library, I am getting 2 errors for missing libraries. I can see that I am using newer versions of these in the library manager (3.5.17.0 and 3.5.19.0 opposed to 3.5.8.0 and 3.5.7.0 stated in the errors). IDE Version is V3.5 SP19 Patch 6. The "Download missing libraries..." button in Messages list is not doing anything. Why is it looking for older versions of these libraries? Can this be fixed by using the newer versions? How can I download & install the older version of these libraries?
