Post by andrax on CodeSys Raspberry pi I2C driver not found ^{CODESYS Forge talk (Post)}
I took a look at your project. First of all, a Raspbery Pi4 is installed. You must use the GPIOs_A_B(GPIOs B+/Pi2). The error ULINT can't be set to IDINT.... with your project as well. If I change your project to ‘CODESYS_Control_for_Raspberry_Pi_SL’ the error is gone.

Post by gseidel on Strange problem with the ‘MC_SetPosition’ function ^{CODESYS Forge talk (Post)}
Hi Gustavo, can you reduce the problem to a project that reproduces the issue without the real servo drives? (You could set the servo drives to virtual and strip away as much as possible from the application.) If you can attach a project, we will have a look. Best regards, Georg

Post by pernockham on Preferred way of managing Ip-adress/es for linux (debian) host? ^{CODESYS Forge talk (Post)}
I have a debian linux host running Control SL. I tried to manage IP-addresses through codesys/Control SL but that was not successful. What works though is manually editing the network-interfaces config file. /etc/network/interfaces. Is there a way to set this up so that IP-addresses can be managed from within codesys instead? Thanks! / Per

Post by jeffersonhui on SP20 Visualization Element Dynamic Colors ^{CODESYS Forge talk (Post)}
I am using Codesys SP20 patch 5 and in a visualization element, the "Color variables" section does not have a section to set up dynamic color values linked to variables. In a previous version (SP18), I get the option to add variables for Normal & Alarm state colors. Does anyone know how to get the dynamic color variables to work?

Post by manuknecht on FileDialog - OnDialogClosed not called anymore ^{CODESYS Forge talk (Post)}
I had similar issues with the OnDialogClosed not being called. I realized that this behaviour is resolved, when the according visualization object on which the input configuration is set is moved to the foreground. Somehow, the object has to be one of the lowest elements in the Element List (i.e. in the foreground) for it to work.

Post by atone on Set DeviceID of an IO-Link Sensor at Runtime ^{CODESYS Forge talk (Post)}
Answering to myself: is not possible according to the IFM support, this possibility has not been taken into account, although the interfaces and FBs in Codesys would apparently support it. So I ended up having to deactivate the sensor validation and the backup & restore functionality in the master and implement it in the PLC myself.

Post by gseidel on Dynamic target position tracking ^{CODESYS Forge talk (Post)}
Hi kporter, a more direct way would be to use SMC_FollowPosition to write the set positions directly to the servo drive. This FB has reacts on changes of the fSetPosition on each call, without a need for a rising edge on Execute. See https://content.helpme-codesys.com/en/libs/SM3_Basic/Current/SM3_Basic/POUs/Movement/Direct/SMC_FollowPosition.html. Best regards, Georg

Hello, I'm having a similar issue with buttons. I want to be able to set the default color and transparency of a button. I've tried a lot of different iterations like KNewman, but to no avail. Has there been some documentation released since KNewman posted this, or is the style editor still as undocumented as ever?

make sure the PLC and the programming PC have IP addresses that are on the same subnet, you'll have to know the default address of the PLC or you may need to connect to it with a special cable and use a software tool to set the IP address.

Post by durstloescher on Library Documentation DocScripting ^{CODESYS Forge talk (Post)}
Hi, I am currently creating a documentation for our library with DocScripting. In the process, I noticed that Visu images are created before the merge and transform, i.e. "screenshots" of the different Visus. Unfortunately, these are not used in the later process (Merge/Transform). Is there a way to set it up so that they are found in the html file?

Post by fless on How to change bHiresMode ^{CODESYS Forge talk (Post)}
you need to set the increments to 10 (the screenshot shows 10000 hex = 65536). all the turn settings to 1. and the application units to 366. But usually you use the resolver resolution per motor turn. Insert the gear ratios (1:1 for no gear) and the last field you put the circumference of your drive wheel.

Post by stuartjr on Disabling forcing of specific variables ^{CODESYS Forge talk (Post)}
So I think I've found a way to do what I want, but its a not as simple as I thought it would be. Essentially I've got to put my "logic" that decides what the GVL variable should be at the start of every task (rung 1). Then regardless of what the force is the variable will be set to what the logic decides.

There are examples installed when you install codesys. they are located in C:\Program Files\CODESYS 3.5.19.50\CODESYS\CODESYS SoftMotion\Examples The examples won't be specific to your drive, though you haven't specified the exact drive. After you add the device to the ethercat master you can click on it and set pdo etc

Post by trusty-squire on Confused by dwIpoTime input for SMC_Interpolator ^{CODESYS Forge talk (Post)}
Hi, Learning Codesys CNC, and I am confused by the dwIpoTime parameter. I have a basic demo application, using SMC_Interpolator feeding into SMC_TRAFO_Gantry2Tool2, which then sets the position of the x/y SM_Drive_Virtual axis. I also have a C axis which revolves the tool, which is controlled using a simple tangential angle calculation SMC_CalcDirectionFromVector. The GCode I'm using has feed/accel set at 500. The axis configuration limits are well above that (2000). What's strange is that, when I run the simulation, the feed speed changes drastically when I update the variable dwIpoTime. The larger the number, the faster it moves. What's going on here? The documentation only says "This variable has to be set for each call. It represents the cycle time in μsec." Why does it change the feed speed I'm seeing the in simulation? What is a good number to use? The example I was looking at set it at 5000. Screenshot attached.
