Post by jrsantab on Remote connection to ifm PLC & HMI ^{CODESYS Forge talk (Post)}
Hello, We are trying to access remotely a PLC (ifm 711S) and a HMI (ifm CR1077). Both are connected to a Teltonika RUT200 router. We establish the connection with OpenVPN Connect and can ping both controllers. We have a laptop that, most of the time, will allow Codesys connection to the controllers, but we have several other computers that are unable to connect, although all of them can ping successfully. We cannot find any difference in the configuration or software installed from one PC to another. If we connect to the router by WIFI, instead of VPN, all the computers work fine. We know that scanning the network will not work over a remote connection, so we input the controller IP directly. Has anyone had a similar problem and can offer any hint on what to check to make the connection run?

Post by danwoodlock on Rpi zero w lost license after 4.11 update ^{CODESYS Forge talk (Post)}
Hello all, Encountered an issue with my zero which seems to have happened after the 4.11 update. It now runs in demo mode (2hr) and I am trying to see what the appropriate steps are prior to contacting codesys directly. Background: I recently did a fresh install of w11 on my pc, so it seems "c:\ProgramData\CODESYS\Licenses\" only has information related to my pi5, which I licensed just this past Friday. I have all my license documentation about my rpi zero as far as the emails received, but when I try to claim using the ticket number it says its already been used, or something to that effect, which it was. Currently trying to perform device license reader, which is taking some time.

Post by k2saki on CNC / G-Code streaming processing ( to start quickly in long G-Code File ) ^{CODESYS Forge talk (Post)}
Is it possible like G-Code streaming processing (like FANUC or SIEMENS DNC Function )? Or Does anyone know the tips for CODESYS Motion to start moving long Long G-Code File quickly? I have to wait long time after "Start" button to start moving, I have to wait finishing interpreting whole G-Code file, ( and I have to prepare huge buffer to store. ) Now, I'm working on my CNC Project using SMC_ReadNCFile2, and SMC_NcInterpreter to preprocess G-Code. I tried to set SMC_Interpolator.xExecute to true to Start while after SMC_NcInterpreter processed more 50-line of G-Code, but that not worked, I had to wait SMC_NcInterpreter processed all lines to start SMC_Interpolator. G-Code have about 2000 lines of XY of G01 (or more over.. ) of short segment that a CAM software has exploded from NURBS Curve.

Post by jens on Modbus tcp - channel ^{CODESYS Forge talk (Post)}
Help wanted This is the first time i'm doing a Modbus Tcp project. I have some VLT with a extension module MCA-122. i'm currently unable to write to the VLT slave, but i can read from status word parameter=1603 and address := 16029 where the address is calculated from parameter is ((id x 10)-1). in the manual the functions that are supported are 3 hex, 6 hex, 10 hex, b hex and 11 hex. read holdin registers, write single register, write multiple registers, get comm. event counter, report slave id. i'm only using the Modbus Slave Channel is this wrong when trying to write to the vlt ?

Post by tayhim on WAGO HMI Device not found ^{CODESYS Forge talk (Post)}
Hello, I'm trying to connect with a Wago TP600 HMI but without success. I'm using codysis 3.5 SP19 patch 7 (SP20 block all the time) and the official wago package is installed. However, when I scan and select my device, I get a message saying that the device doesn't match the project's device object with the possibility to update the device (as shown in the attached picture). however, after choosing to update i got a message that the device is not found. I've tried with a new empty project but the same results. do you have any ideas? Thanks.

Post by timvh on CPU + EtherCAT redundancy ^{CODESYS Forge talk (Post)}
It works well with two Wago 750-8210's. I helped a few customers setting this up. But it should work with any device which can control EtherCAT I/O, is real-time and has sufficient network interfaces. Two network adapters can be used to create a redundant EtherCAT network (you need 2 additional switches for this). The other network adapters can be used to interconnect the 2 PLC's (synchronization). We noticed that if you exchange variable lists that there could be some issues if you have long lists. So what we did is use a SoftPLC on a server that contains all the settings which continuously sends network packages (GVL sender) and which is received by both PLC's (network receiver). Switching over is done in milliseconds. The bus doesn't notice the change-over. EtherCAT communication works flawlessly.

Post by dat422 on CODESYS crashes when adding standard OPC UA Information Model to Communication Manager ^{CODESYS Forge talk (Post)}
Hi all, I am experiencing a problem when trying to add a standard OPC UA Information Model to the Communication Manager. When I try to add the following standard information models to a new or existing project http://opcfoundation.org/UA (15.07.2020) http://opcfoundation.org/UA/DI (02.06.2020) CODESYS crashes every time during the process. Adding an OPC UA Server itself works without any problem. The crash only happens when adding the standard OPC UA Information Model. CODESYS version: CODESYS V3.5 SP20 Patch 4 (64 bit) Has anyone experienced the same issue or knows a possible workaround? Thank you in advance.

Post by steven-schalm on Frustration-Fueled Feedback on Project File Management and Git Integration ^{CODESYS Forge talk (Post)}
Yes, it's very tedious, especially since Codesys 4 is a custom web development... At Rex Automatisierungstechnik GmbH, we've invested a lot of time in the Python interface to enable something like CI/CD, but also to export the code and re-import it after making clean modifications. Also, the fact that a class/function block is just a single file containing all the methods, props, etc. Yes, and right now I’m building my own VS Code extension with a clean LSP (Language Server Protocol) for ST, as well as an st-validator, st-formatter, st-linter, codesysPackage.json, and codesys_modules folder... Best regards, Steven Schalm / Sharok6130
