Post by docker on Webvisu client connection monitoring ^{CODESYS Forge talk (Post)}
Hi mate, With this snippet i was able to see the lastusage variable count, but it would not iterate between clients? i was only able to access the data of the target visu. it threw an error with the array of pointers stating it was not able to convert etc. also when i tried it with the while loop it created an endless loop and crashed the program. any ideas? Thankyou

Post by pernockham on How to manage soft container licenses for (remote) multi units? ^{CODESYS Forge talk (Post)}
Using Codesys runtime for Linux and thinking of the process of preparing multiple such systems for my customer. I don't necessarily have physical access to these units, they can be (very) remote. The idea so far is to use an image to install the Linux OS and codesys runtime. Application updates can be done by distribution of the PlcLogic/Application/application.app and application.crc files. But whats the most practical way of managing the license for these units? Do each controller need to be physically connected to a License Manager instance or can licenses be distributed by means of a license file for each unit? I believe that the license should be stored in soft containers for each unit. Help and insights appreciated! Per

Post by mp9876 on Device User Logon ^{CODESYS Forge talk (Post)}
Following up on the invalid user authentication on the target Not 100% sure what the problem was but following my post I managed to create an administrator level user. Then my next issue was that I could not connect to the device. I might have flipped the device from a 64 bit version to a 32 bit version so I did UPDATE DEVICE back to the 64 bit version; still could not connect somehow. Then I did two things at the same time that fixed my problem: Wiped the Codesys Control Win 64 bit version and installed the 32 bit version Installed latest Codesys Control Win V3.5 SP20 (released today) I wish I knew which one of these actions fixed the problem but at least the problem is solved. Hoping this post may help someone one day

A standard string is actually a list of bytes that represent the ASCII code for each character. The following part of code will give you the ASCII code of one of the characters in the string: byChar := sInput[i];

Hi, do you process the sentences subsequently? If not, the function block fills the sentences (queue) and waits for the sentences to be processed, so that new sentences can be read and filled to the queue.

Dear Tim, This is the missing link for me. I was not aware of the fact that the docker container is claiming the smallest possible license. Now the serial number makes much more sense. Thank you

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 <index_name> : <index_type>; // One or more index parameters are declared here END_VAR</index_type></index_name></data_type></property_name> GET Code that uses <index_name> to return a value END_GET</index_name> SET Code that uses <index_name> and the implicit variable <property_name> to write a value END_SET</property_name></index_name> END_PROPERTY Option 2: PROPERTY <property_name> (<index_name> : <index_type>) : <data_type></data_type></index_type></index_name></property_name> GET Code that uses <index_name> to return a value END_GET</index_name> SET Code that uses <index_name> and the implicit variable <property_name> to write a value END_SET</property_name></index_name> END_PROPERTY

Post by acc00 on Redundancy Codesys Runtime, Synchronization ^{CODESYS Forge talk (Post)}
Hi, I’m currently testing the Codesys Redundancy application with 2 Raspberry Pi, with the idea is of using in my project 2 Wago PFC200 and 1 Ethercat Master with 2 Remote IO. After I configure the redundancy, and one Pi is Active and the other is Passive, if I disconnect the Ethernet cable of the Active, the Passive become Standalone, which is good, but the problem is the following: -When I recover the Ethernet connection, both stay Standalone. They will NOT Sync until I do it manually in the Codesys environment. How to make the synchronization automatically? -If both Pi/PLC stays Standalone, who is managing the IO? (Ethercat and Serial) I have done a test with an Modbus Slave, where I am sending a counter that increase every second. And I see that when both PLC are standalone, they both keep an active connection with the Slave, and both write values. This does not seem good, since according to this in my project both PLC would try to control the IO at the same time. Note: The Codesys have an option (greyed out, not possible to select) which says “Auto Sync”. What is the purpose, and why I’m not able to select it? I'm using Codesys Control for Rapsberry Pi 64SL Runtime in my test environment (2xRaspberry Pi 4), with the idea of using Codesys Control PFC 200 Runtime in my project (2xWago PFC200 and 1 Ethercat Master with 2x Wago 750-354 Ethercat Fieldbus Coupler). Using the last Codesys 3.5 version (SP19 PAtch 5). I'd appreciate a lot any help on this questions!

Post by yannickasselin on Lenze i950 Servo and WAGO PFC200 ^{CODESYS Forge talk (Post)}
I don't have time to go through the whole manual but as I said earlier, the servo drive does not support any of the modes needed for SoftMotion Light to work. If you want to use the full SoftMotion, you could use SMC_Homing function block to do the homing. This function block does not use the Homing Mode. It still uses the CSP mode and does the logic in Codesys runtime instead of in the servo drive. Read the documentation about it to see if it fits your needs. But if your controller only supports SoftMotion Light, I am afraid you will not be able to use the i950. I do a lot of motion stuff with different servo brands. Some support all the modes needed for SoftMotion Light and some don't. You really need to make sure the modes are supported before choosing a brand over another. I tend not to use brand specific controllers in order not to be limited by their supported features. I usually choose a PC (Linux or Windows) and install the Codesys runtime and licences myself. This is the most flexible way to use Codesys in my opinion. Depending on how many axes are needed in your project, a full SoftMotion license may not be more expensive than SoftMotion Light because SoftMotion is available as Application based license whereas SoftMotion Light is not. But of course, SoftMotion is harder on the CPU than SoftMotion Light.

This came up again today, so I'll post the fix for future reference. Happens with Schneider Machine Expert 2.2 and M262 controllers. Add this bit of code to a program called from the visu task //disable "VisuFbFrameBase.SetInputPositionData" log messages, which fill up the logs IF VisuElems.Private_Visu_Globals.g_ValueChangedListenerManager.GetListenerCount() > 0 THEN VisuElems.Private_Visu_Globals.g_ValueChangedListenerManager.RemoveValueChangedListener(VisuElems.Private_Visu_Globals.g_ValueChangedListenerManager.listenerForOnValueChanged); END_IF

Post by davidking on Error, visualisation property handling, VISU_USEPROPERTYINFO ^{CODESYS Forge talk (Post)}
Solution: Disable VISU_USEPROPERTYINFO define Go to Project → Options (or Project → Properties, depending on your CODESYS version). Find the section called Compiler Defines. Look for the define: nginx Copy Edit VISU_USEPROPERTYINFO Delete it from the list, or uncheck it if it’s a checkbox. Save your changes and try compiling the project again. → This is the right approach if you don’t need property handling for visualization elements.
