Hello. Is there an Example for BACnet IP Client in Codesys? An applicable example makes it pretty easy to understand.

Post by kevinrn on Github Actions CI/CD tasks - development topic ^{CODESYS Forge talk (Post)}
Hello community, I just want to inform you about our plans and the current status of automating the build process for CODESYS libraries. So it might be helpful for some people who are in the same situation. Background story: I am a software engineer at powerIO GmbH, normally I use high level languages for the products we develop and offer. Sometimes I work with my team on CODESYS libraries, which can also be found in the CODESYS store. Most of the time I spend with them on architecture tasks and tasks that are not directly related to our products. Every time I see the manual processes for releasing a library etc., I am very surprised about this time intensive process. Current situation: I know there has been a scripting interface for years. CODESYS Git was released a few years ago, but the scripting interface was only released a few months (weeks?) ago. We developed a pseudo-automated solution a few months ago, but it was all very hacky. So now there is a better Git implementation and also more modularization and installation options. For example, the CODESYS installer has a full CLI, which makes it very convenient to install CODESYS installations headless. Plans: I think it's the right time to develop a better automation solution. Most of our software projects are hosted on Github and we use Github actions very intensively for other software projects. Therefore, we have decided to use Github for our CODESYS library projects as well. Following tasks should be implemented in automation for CI/CD tasks: - Automated setup of CODESYS installation (Already released: https://github.com/marketplace/actions/setup-codesys-installation) - Checkout CODESYS libraries - Execute tests scripts - Sign CODESYS libraries - Extract Library documentation - Create CODESYS package - Sign CODESYS package Side Note: - This is mainly a side project, and we do not provide support for the CI/CD part. - This topic is here to help and also to get help from other software engineers. - This project and idea is not prioritized as I am currently the only one working on it and I hope it will help us and also others and increase productivity. - We are putting this out there as an organization, but priorities can change quickly and the CI/CD tasks I am developing are mostly done in my spare time. So please don't expect this to happen in a short time or even be fully completed. I would be very happy if some ppl will join the development process and might be open to discuss some technical details for this. I hope this topic is not to off-topic, but I think the CI/CD part is very important today and it can increase a lot of quality and push productivity. Thanks :)

Post by sachem on SysFileGetTime problem ^{CODESYS Forge talk (Post)}
Good morning. I'm working with a Weidmuller controller using Codesys. My project use OPC-UA to communicate an application in my pc with the controller. Yesterday, I installed the license of the controller and test it, and the communication works perfect. I use the communication with anonymous login, and works fine. But, hours later, the anonymous login don't work, and the controller only allows connection via OPC with username and password. Someone know why this happend? Thanks

Post by gilbertamine on Comparing Arrays of structure ^{CODESYS Forge talk (Post)}
Hi Everybody, I'm looking for a simple way of comparing two array of a structure. My structure is define like this : TYPE Positions_T : STRUCT PosX: DINT; PosY: DINT; PosZ: DINT; END_STRUCT END_TYPE I have multiples Var : ARRAY [0..220] OF Positions_T, that I need to compare quickly. I don't really want to do a Loop that goes by every 220 points and compare each one of them so I was wondering if there is another way. I came accross the MEM.Compare function, but it require to know the size in Bytes of the memory, and I don't know how to do that... Has anybody an idea on how to do the comparing easily ? Thanks in advance

Post by peterkcontrols on Copying 2 byte word to output ^{CODESYS Forge talk (Post)}
Hello. I am using codesys 3.5. I would like to know if it is possible to set a variable to an output without declaring in. I have defined a STRUCT and within this struct I have a Struct for inputs called I and a struct for outputs called O. I have declared a variable of the type of this Struct, I would like to set or alias the value in this variable to an input/output value of an IO block that has a module on the ethernet tree. Is it possible to copy the contents of %IW0 -> STRUCT.I ? The size of both of these is 2 bytes. I understand that I can declare a variable with the input like Input01 AT %IX0.0 : BOOL; However how can I make STRUCT.I.D00 AT %IX0.0? Is this possible? Thanks
