Post by dhumphries on Rounding error in simple addition ^{CODESYS Forge talk (Post)}
I have discovered a rounding error, either in Codesys or in my understanding of numbers. The attached ladder shows that when the up button is pressed the number increases by 0.1, when the down button is pressed number decreases by 0.1, after several button presses the number isn't equally divisible by 0.1. Have I discovered a bug or am I doing something wrong?

Hello, I'm trying to use FILE.Open to open file that exists in the given location. sFileName is formed from "Copy as path" in Windows. So I'm sure file exists and it is in the given location. And still, I get thiss denied error. What could be the problem here? Attached is a screenshot with current implementation.

Hello. I am a new user. On generating the first test project I am receiving this error message. You are using inconsistent overlay settings, please check your compilerdefines for the current application (-> GENERATE_OVERLAY_VISU) and the setting within the visualization manager. Can anyone help?

Post by culius on How to reset AzureMQTTClient after error? ^{CODESYS Forge talk (Post)}
Hey Guys, is there any chance of direct reset of the AzureMQTTClient? When the Client runs in an error, I can not reset the client whit switch xEnable to off and on again. I always need to make a hard reboot. Any Ideas, or have someone else experienced this behavior? Kind Regards

Good morning, Yes, this is a known bug that has been reported. For now, the only workaround is to open the function block instances from the device tree. Regards, -Shawn

You cannot create an array of Programs. Create a Function Block for this purpose instead of a program. You can create an array of FB instances and call each instance in a loop.

Post by tk096 on Creating Custom Kinematics ^{CODESYS Forge talk (Post)}
Hi, a few questions that you can check regarding your kinematics: * Does your kinematics FB implement the interface ISMKinematicWithInfo2? * Does AxesToCartesian(a, out f) -> CartesianToAxes(f, out aCompare) result in a=aCompare for random positions a? * Do you return a valid rotation matrix f.mR (SMC_Matrix3) in AxesToCartesian()?

Hello I'm using the MQTT_Client_SL library. Very good so far. One of the inputs to the MQTTClient FB is hCert (RTS_IEC_HANDLE). Which function do I need to use to get this? Or do I add a FILE library? thanks

Did you create a certificate on that device already? Go to the menu View - Security Screen and check the certificates on the device. There should be one for your webclient FB.

Die im FB 'zeitschalter' deklarierten Variablen sind nur lokal gültig und global nicht sichtbar. Deshalb kannst du in'PLC_PROG' nicht darauf zugreifen. Hier must du entweder eigene Variablen deklarieren oder globale Variablen in einer globalen Variablenliste (GVL) anlegen. mfg Reinhard

Thanks for the update, Since you can't double click is there another way to enter the FB when online and see the running code of that instance? When can we expect to see v1.0?

Post by fless on See only variable ^{CODESYS Forge talk (Post)}
either you have "Insert with namespace" enabled in the SmartCoding options or your GVL_GLOBAL starts with {attribute 'qualified_only'} btw it's considered good practice to put the namespace in front of the variable. you could have variable with the same name in your PRG or FB.

Hi, I have the same issue. It should be possible to create a certificate without using Codesys IDE. The functionality of the security agent could be handled in some fb. Can anyone here give the right hint?

Hello, you probably fixed in this meanwile, but I think your problem comes from dependencies of other libraries. I see in the Project column of errors the "caa types extern" and "caa fb factory", that both have dependencies. Try to check there. Regards, Francesco

Post by salvadegianluca on How to use TON inside an FB that is instanced within a Visu page ^{CODESYS Forge talk (Post)}
Hi everyone; I'm building a project in which the drag of the mouse over some controls (or the click event) changes the background color of the control items; this change of color is made with an FB that assignes a color code to the background with MUX command based on the value of an enumerator, this part is perfectly working but, when I'm using a touchpanel instead of a web visu (controlled by a mouse) I get into some issues as it seems that the touch operations are not triggering the MouseEnter and MouseLeave properties as it's done with the mouse.... For this reason I'm trying to add a TON to my FB and, if the enum that changes color remains at the same state for more then 3s I'm automatically resetting it to it's "0" so the item gets back the not selected color. Anyhow it looks like the TON function from library is not working in these FB that are instanced in the various visualizations, as instead they do if I create some instances within the POUS. Anyone has ideas of how to make them work?
