Post by fontrap on cmDongle Raspberry Pi issue ^{CODESYS Forge} ^talk ^(Post)
Hello mates, I'm working with CODESYS V3.5 SP20 on a Raspberry Pi and I use "Raspberry Pi MC SL" as device on the project. I've installed the Control Standard L (multicore) license on a Wibu System usb-Dongle (cmStick/4.50) that already had another license from another vendor. I follow the online activation procedure from CODESYS documentation. Raspberry Pi has already CodeMeter installed for the other license. When I plugin the dongle on Raspberry and start the Runtime from Raspberry Pi Update in CODESYS I receive the message that I'm on Demo mode because the license is missing. I double checked that the license is activated in the dongle, through the WebAdmin of CodeMeter and the second license runs properly without any issue. I have already try to change the dongle from HID to MSD device and backward but the the Runtime cannot recognize the Dongle. I have also try to stop and start the Runtime through CODESYS without success. Is there anything else I can do to fix this issue?

Maybe select the local gateway instead of the gateway on the remote device?

I had one RPI device where I could login. I copied the SD-flash over to another SC-flash. This new SD-flash was inserted in the new device. I can boot the new device but I cannot login why? How can I install an application on this new device?

Post by cedriclee on RaspberryPI reconnection error ^{CODESYS Forge} ^talk ^(Post)
"Hello, I'm Cedric Lee, a PLC engineer based in Korea. I'm reaching out about an ongoing issue with the connection when attempting to control Beckhoff modules using Raspberry Pi with CODESYS for the first time. I use CODESYS to target the Raspberry Pi's IP, install version 4.10.0.0 of the CODESYS Runtime Package, and upon pressing Start in the Runtime, the target connects to the Raspberry Pi. However, within about a minute, an error window appears, stating 'no connection to the device. please rescan your network,' leading to the disconnection of the target. This cycle repeats. I've attached some pictures for your reference. I'm using CODESYS Development System V3, Raspberry Pi 4 Model B (installed as 64-bit), and Beckhoff EK1100 modules. If anyone has a solution to this issue, please help. Your assistance is greatly appreciated."

Post by alexgooi on Codesys OPC DA server requires more then 2 GB of ram ^{CODESYS Forge} ^talk ^(Post)
Dear Forum, We are currently running into a problem that the CODESYS OPC DA server is running out of RAM (larger than 2 GB). We have a setup of 10 Codesys controllers which features around 300.000 discoverable tags per controller. We are only interested in 10 percent of the tags to be communicated to the OPC-server, this is due to the fact the program consists of arrays of objects which on their part implements arrays of objects, simply reducing the number of discoverable tags is not an option The OPC-DA server loads all the discoverable tags, is it possible to: 1 let the OPC-DA server only load the tags that are requested by the SCADA/MES system. 2 let the OPC-DA server claim more memory. 3 run 2 OPC-DA servers in parallel? Thank you in advance

Post by cdutz on Problems connecting to Codesys 4.9.0.0 runtime on my Wago PFC200 ^{CODESYS Forge} ^talk ^(Post)
Turns out I managed to get a connection to my PLC. It seems that a few weeks ago Wago released something with version 4.3.3(25). So I reset my PLC to Factory-Reset, set it to the 192.168.1.17 IP and changed the IP to the one I wanted with the Wago EthernetSettings tool. Then updated the latest firmware using the WAGOupload tool. Now the PLC came back up without a PLC runtime running, so in the Web-tool I wen't to the "Configuration"/"PLC Runtime" and selected the runtime version "CODESYS V3". I uninstalled all Codesys versions and installed the version from the download package of Wago together with all the packages the bundle provided. After creating a new project I didn't select the old PFC200 runtime, but one of the dozens of new device profiles, that it now listed. With these settings I was then able to connect to my PLC. Now I hope I'll get the existing project that I had ported to this new structure. Sorry for the noise. Chris

Post by shaunvdm on Canbus Slave SDO Read from Object ^{CODESYS Forge} ^talk ^(Post)
Busy testing a solution to use Canbus Slave to replace a physical device and convert to Ethercat device but keep the Canbus Master in place. Master needs to Read SDO object 5FA2. In the Master PLC if i send the SDO with 8 bytes in message IE: 60B 40 A2 5F 00 00 00 00 00 i get my expected 58B 43 A2 5F 00 00 68 36 02 containing data back. Problem is if we issue a 4 byte command can send 60B 40 A2 5F. Surely the canbus slave should respond with a 58B 43 A2 5F 00 00 68 36 02 but it comes back as 80 A2 5F 00 00 00 00 08 - meaning this OBJECT does not exist. Is there a setting in the canbus slave driver for Canbus to allow the 4 byte command to read the SDO OBJECTS ?

Post by lzml on Safety ^{CODESYS Forge} ^talk ^(Post)
I have a problem with a project that uses EtherCAT Safety. The project is developed with CODESYS version 3.5.19.20, runtime 3.5.18.30, safety CPU EL6900 4.3.1.0, TCEL6900FBS 3.5.1.10, IODrvEL6900 4.3.1.0, IODrvEtherCAT 4.1.0.0. The safety project works correctly, but when I download the PLC project for modifications, the ESM objects are no longer aligned with the states inside the safety program. Specifically, inside the safety program, they are seen as true, while outside the safety program, the state is reported as false, but not for all ESMs, only some. I have already tried to completely redo the safety from scratch, but nothing has changed. Any solutions? Thanks

Post by valenting on License problem with Raspberry Pi ^{CODESYS Forge} ^talk ^(Post)
Hello, I have a raspberry pi with a license installed, but Codesys stops after 2 hours, and when I start it manually I have the following message: pszInfo=!!!! no runtime license - running in demo mode(~2 hours) I tried using License Manager, and got the following message: Licensing info not available. There is no dongle attached to the device. I have this message frequently, and usually removing the content of /var/opt/codesys/.cmact_license makes it work. After doing it and restarting Codesys, I have an empty Softcontainer without my License. I tried using "Install license" using the .WibuCmRau file for the corresponding license and got the following message: Licensing info not available. The device does not support this service. I also tried using Additional Functions > Restore Licenses with the Ticket ID and got the following message: This device does not support automatic license backup. How can I reinstall the license to this Raspberry Pi?

Post by marekxc on Error C0521 - unknow compiler ^{CODESYS Forge} ^talk ^(Post)
Select in tree "DEVICE", right-click and select "Update Device" Select "Library manager" and Change the version of the Library (down manualy). Samoetimes "Try reload Library". If you open a project version 3.5.19 in version 3.5.16, there are difficulties.

Good morning, Yes, this is a known bug that has been reported. For now, the only workaround is to open the function block instances from the device tree. Regards, -Shawn
