Post by sbrauns on Codemeter log error: API Error 200 (ENTRY NOT FOUND) occurred! ^{CODESYS Forge talk (Post)}
Hi, I am using Codesyscontrol for linux 4.11 with an USB dongle with license. The log file from codemeter shows a constant error message which repeats every minute: Entry (6000437:8755) not found - Event WB0200 (ENTRY NOT FOUND), Request IP-Address local(IPV4) with UserLimit API Error 200 (ENTRY NOT FOUND) occurred! The log file from Codesyscontrol itself shows runtime licensed and I experience no other issues. But I am still concerned about the error message in the log file. Does anybody know what this is and how to fix it? thanks

Post by k2saki on CNC Open Source Project / Can I convert my project to text-files ? ^{CODESYS Forge talk (Post)}
Hi. I published My CODESYS-CNC Project to GitHub and I set it Open Source Software. Here https://github.com/k-s-saki/RPi_CODESYS_CNC My CNC Project is binary file , using FBD for IPO , so I found it is a little bit hard to work with people on GitHub. (diff / merge ) My question is 1) Is it possible to convert my project ( only POUs is also fine ) into text file ? How? 2) Would it be better to rewrite all FBD/LD into ST and copy them manually to text files? Thanks.

Post by alexgooi on FB_INIT in library ^{CODESYS Forge talk (Post)}
Dear Forum, I currently have a challenge. I have a library with some communication classes. These communication classes need to be linked to an interface like this: Devices_and_controllers.Comm_Frame.Modbus_GVL_Link.KNX_TCP[Interface_Index] := THIS^; This is executed via a FB_Init() method. When I try to do this in a program this works fine. But when I declare the FB_Init() in the library the FB_Init() method is being called but the link is not made (interface still has the value 0000000000). The Objects and interfaces are defined in the library (GVL), so I’m assuming the data should be there. When I call the FB_Init method explicitly in the program it also works fine. Whys is this not working when it is all defined in the library? And is it even possible to create a structure like this in Codesys? Kind regards Alex

Post by starmaxou on How to download dependencies packages for CODESYS Control for Raspberry Pi SL ? ^{CODESYS Forge talk (Post)}
Hi everyone, I'm trying to install the CODESYS Control for Raspberry Pi SL package. The computer with CODESYS software is offline for security reasons. So, I downloaded the package on another computer and installed it manually. But this package has dependencies packages: CODESYS.Control SL Extension Package, V4.0.0.0 CODESYS.Control SL Deploy Tool, V4.10.0.0 As I said, the computer with CODESYS is offline. I cannot use the package installer to search for these packages. I did not find them in Codesys Store with another computer. Do you know where to find and download them? Thank you in advance for your help!

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 ?

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 s1mon on Two OneWireMaster on one Raspberry PI 5 ^{CODESYS Forge talk (Post)}
I don't know why the EtherCat fails, but what happens is: First I have only one 1WireMaster running on my Raspberry Pi and EtherCat is running fine. Then I'd like to add a 2nd 1WireMaster. Therefore I enable a 2nd GPIO Pin on the raspberry in the file "/boot/firmware/config.txt". dtoverlay=w1-gpio,gpiopin=4,pullup=0 dtoverlay=w1-gpio,gpiopin=23,pullup=0 To be able to use this 2nd 1WireMaster in Codesys Runtime I Adjust the CODESYScontrol.cfg file and add there: PlaceholderFilePath.2=/sys/devices/w1_bus_master2, $OneWire2$ After a reboot the EtherCat Master is not working any more. I didn't even add a 2nd OneWire Master in Codesys, but still if I do the EtherCat does not work. Do you have an idea why?

Post by mait-tim on Drive communication errors ^{CODESYS Forge talk (Post)}
With a machine I'm working with i get a communication error when I'm updating some softstop limits. As soon as I update the code the drives do not want to operate. Using the MC_readStatus I'm receiving errors as soon as i want to start a movement. Using MC_ReadAxisError i see that i receive error 131, no response. With a SMC3_ETC_ReadParameter_CoE i do not recieve any driver errors. Does anyone know how i can figure out what the error is and how to solve it. When i go back to the old software no errors occur. Im working with a legacy machine running a Beijer PLC with some Mitsubishi drives. running on Codesys 3.5 SP10. the runtime version is probably 3.5.3. The drives are all Ethercat Drives (CoE). All using the SM3_drive_ETC libary and the SM3_basic library.

Post by timvh on Codesys complains about matching versions ^{CODESYS Forge talk (Post)}
Open the CODESYS Installer. Create an export file from your current PC from your current version. Then on the other PC Open the installer and install a new version based on the same essentials version, but additionally select the export file which you have created on the first PC. Or just install (import) it within the already existing version. For the installer, you can install it from: https://store.codesys.com/en/codesys-installer.html For help see: https://content.helpme-codesys.com/en/CODESYS%20Installer/_inst_install_setups_and_addons.html On PC 1, save the project as projectarchive (which will then include all the libraries and devices). Then extract this projectarchive on PC 2.

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.
