Post by pikebuster on Help for a newbie ^{CODESYS Forge talk (Post)}
Can somebody help me with this? I have problem with the button! This task must be solved using Sequential Function Chart (SFC), IEC 61131-3. TASK Create an SFC program to control a traffic light at an intersection. Description: You will program a traffic light that has three phases: Green, Yellow, and Red. The traffic light must follow these rules: Green light is on for 10 seconds. Yellow light is on for 3 seconds. Red light is on for 10 seconds. If the pedestrian button is pressed, the system must keep the red light on for 20 seconds during the next cycle. After the pedestrian has “crossed,” the system should return to its normal cycle. Basic Steps: Initialization: Start by setting the traffic light to Red. Green Phase: After 10 seconds, switch to Green. Yellow Phase: After 10 seconds in the Green phase, switch to Yellow. Red Phase: After 3 seconds in the Yellow phase, switch back to Red. Loop: Repeat the cycle. Use, for example, lamp symbols in the visualization module to simulate the traffic light. You may also add a simple pedestrian light if desired.

Post by e13740e on Parameterized Property syntax for array element processing ^{CODESYS Forge talk (Post)}
Hello. I'm trying to create a Parameterized Property(CDS V3.5 SP21) to avoid copy-pasting code for processing array elements. I can't seem to get any result. Perhaps I am making a mistake with the syntax. None of the declaration options below are accepted by the compiler. If you know and use them (Parameterized Properties) in your work, please let me know. Thank you in advance. Option 1: PROPERTY <property_name> : <data_type> VAR_INPUT // One or more index parameters are declared here <index_name> : <index_type>; END_VAR</index_type></index_name></data_type></property_name> // Accessor for reading GET // Code that uses <Index_Name> to return a value END_GET // Accessor for writing SET // Code that uses <Index_Name> and // the implicit variable <Property_Name> to write a value END_SET END_PROPERTY Option 2: PROPERTY <property_name> (<index_name> : <index_type>) : <data_type></data_type></index_type></index_name></property_name> // Accessor for reading GET // Code that uses <Index_Name> to return a value END_GET // Accessor for writing SET // Code that uses <Index_Name> and // the implicit variable <Property_Name> to write a value END_SET END_PROPERTY

Post by timvh on When Keyboard Key is in Hold, then Webvisu is extreme slow and latent ^{CODESYS Forge talk (Post)}
I'm not really sure what you are trying to do, but maybe you are referring to using the CmpCharDevice library? When you "open" the connection to a device, you can pass flags. What helped me is to set the non-blocking flag. I'm not sure if this is what you are referring to, but maybe it helps: dFlags: DINT := CmpCharDevice.ACCESS_MODE.O_RDONLY + DINT#4000; // see details for flags: http://linux.die.net/man/2/open, + DINT#4000 is for non-blocking hDevice := CmpCharDevice.CDOpen(szFilename, dFlags, Result);

Post by nathant on Can't open online view of FB instance from code editor, only from Device/POU windows ^{CODESYS Forge talk (Post)}
Hello, The title pretty much says it all. When trying to open a FB from the CFC/Ladder/SFC editors while online, the FB does not open in an online view of that specific instance. Instead, it opens an offline view with '???' shown for the value of any variable. This makes debugging extremely cumbersome, as I have to find each FB in the POU window and select the specific instance I am trying to view. Anyone know the cause/solution for this? Thanks.

Post by alink on Visu - changing auto-logout time ^{CODESYS Forge talk (Post)}
Hello is there a chance to set with a visu input the auto-logout time? At the moment, it is a fix value set in visu-manager. But for individual configurating of passwort policies I create a visu-dialog to set policies and there for an option to set auto-logout-time. But till now, I haven't found a solution. Maybe someone has an idea? Thanks

Post by mikek10 on Error IoDrvEthernetIP: Connection Failure. (16#1) How to solve ^{CODESYS Forge talk (Post)}
Your connection configuration should look something like the attachment. Consuming assembly O->T will be the hex of the assembly you want to reference for output data - I want 102 (DO Data Only) shown in the Wago web page 102 = 16#66. Producing assembly (T->O) is the assembly you require for input data - again shown in the Wago web page - I want 108 (DI Data Only) or 16#6C Then set the number of bytes as per the data in the Wago web page too (both 2 in my case)

Hello, Thank you for your response. In my application i use ethercat and while work i do not turn off power. After relative move motor is in standstill. As you suggest I suppose that problem is in drive setting but i do not see any option about increase standstill torque. Below i posted some photos from drive setting manager - PSD Servomanager Do you see any settings responsible for standstill torque? thank you

Post by shawn-plc on Return value from a tag given a string literal ^{CODESYS Forge talk (Post)}
Good afternoon everyone, I am looking for a way to return a value given a string tag path. I put together a pseudo-example to illustrate my use-case and was wondering if anyone in this forum can help. The function fnValueFromTagPath is the function I am looking to either create or use from existing library. I would greatly appreciate it. Please see the attachment for additional detail. -Shawn

Post by mini-developer on Precompilation Error NBS.UDP_Peer ^{CODESYS Forge talk (Post)}
Hello, I use the Library NBS from "caa net base services". After opening the Project i get 19 errors from the message window "Precompilation", most of them because it doesn't recognise a component of the FB "NBS.UD_Peer". (see photo) After compiling the Project at least 2 times, there are no errors. Is there a reason and solution for this behavior? Is there a problem with resolving the library? Thanks for any clue

Additionally, where can I find more information to troubleshoot this issue? Thanks in advance!

Post by dogulas on Removing a symbol from the IEC Symbols Editor grid ^{CODESYS Forge talk (Post)}
gatto, That works. Thanks. Typically I use my mouse more than my keyboard. That's why I was looking for a delete option from the right-click context menu or a delete button on a toolbar at the top. It never occured to me to use the keyboard. It might be a little more user friendly if they allowed a mouse wise ability to remove a line from the grid as well as the DEL key. Just a suggestion. Thanks for your help.

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.
