I am trying to do "update device" in a project which was saved in a different version of CODESYS using ScriptEngine, a dialog with 'Yes' and 'No' button popped up showing that "Do you want to upgrade the storage format for this project? -if you click 'Yes', storage format will be upgraded... -if you click 'No', storage format will not be changed..." I have to click the 'Yes' button automatically by scriptEngine. I know from others topics here in forum, that some dialogs can be auto-answered using system.prompt_answers. And I also get the messagekey of this dialog: Key: "<< No Key>>" Message: "Do you want to upgrade the storage format for this project? - If you click 'Yes',... i have tried using the system.prompt_answers command below, but the dialog was not auto-answered. system.prompt_answers["<<No Key>>"] = PromptResult.Yes Does someone know how to auto-answer the dialog using system.prompt_answers command with messagekey"<< No key>>"? or any suggestions to solve this issue, Thanks!

Post by yannickasselin on Connect to remote PLC via local pc and teamviewer ^{CODESYS Forge talk (Post)}
Yes it is possible. I did it a lot of times using TeamViewer VPN. Unfortunately, TeamViewer VPN only works on Windows. If the remote PLC is a Codesys runtime running on Windows, you should be able to login directly using TeamViewer VPN if it is installed on the PC/PLC. If it is not Windows based, you can still do it but you need to have a Windows based PC acting as a gateway in the middle. In this case you need to enable IP Forwarding on the Windows remote PC (the gateway) and you need to setup the gateway IP address on the PLC to be the address of the Windows PC. Then you need to add a route on your local PC to point to the gateway PC for Codesys communication. I know it may not be detailed enough but I did not want to make a whole tutorial on how to do it. Bottom line, it is possible. I do it all the time.

Post by jonasz on Deploy LicenseServer for Linux SL ^{CODESYS Forge talk (Post)}
Good morning, I'm digging into this topic because I'm curious about resolving my problem in a test environment. In my previous message, I asked about the CODESYS Safe Timeprovider SL package (4.18.0.0), which I saw in the illustration. I noticed that it runs as a service. I am asking about this because from the perspective of an "ordinary" user, this service provides easier access to the settings of the time provider's operating parameters. The basic time provider configuration is outlined at https://content.helpme-codesys.com/en/CODESYS%20Control/_rtsl_virtual_safe_time_provider.html. Why my questions? They stem from my specific case, which is experiencing timeout issues. I know that my environment is currently only a test environment. I'm assuming a real-world scenario in which I won't be able to achieve a better result with my configuration, and I will ultimately need to increase the time provider's cycle time. By running the time provider service, I can easily influence the time provider's operation and thus eliminate the problem. I know, I know, safety systems are not life-enhancing extras.

Post by mp9876 on Device logon problem following fresh install ^{CODESYS Forge talk (Post)}
All screenshots are enclosed in MS Word document. NOTE; 4 questions features at the end. Any assistance would be greatly appreciated! Hi everyone, I am still having device logon problem following a fresh install Here are the STEPS I went through following a FRESH CODESYS Win 64 3.5.19.60 install on a different computer. ‘Gateway not configured properly’ when attempting to REFRESH from the Users and Groups. Then did Gateway manage and confirmed it was ok: This message popped out as it was a fresh install: YES then: Initially went with Administrator twice (user & password) but it did not like it. No device is responding to …: Continued by setting a new user Pressed OK and obtained the following message: Stopped and Restarted PLC at that point: Obtained the following: Attempted to login a 2nd time without success. Then I scanned the network to see if matching device can be detected: Only way to get it detected was to remove the tick in the ‘Hide non-matching devices…’ Attempted a WINK but got a return like this one: REFRESH either @ Users and Groups or @ Access Rights returns: Then created user ‘mp’ at Project level ang logged in: Understandably device user mp9876 was not valid for the Project. Device information A few questions comes to my mind following these connection attempts: 1- Gateway not configured properly message pops out because of a non-compatible device ? 2- Why would the device not be compatible ? 3- Any way to make the device compatible ? 4- Any ideas on how to get this connectivity problem to the device solved ?

Post by manuknecht on Using an Axis of an Axis Group in Torque Conctrol ^{CODESYS Forge talk (Post)}
I don't seem to be able to use an axis, which is part of an Axis Group in torque control mode. I call the SMC_SetControllerMode FB to switch from position to torque control mode, followed by the SMC_SetTorque FB to set the desired torque. This works flawlessly for most axes, however if an axis is part of an axis group, switching the controller mode seems to work without any issues, but the desired torque is never set. SMC_SetTorque does not return an error, but fSetTorque of the axis is never changed. Disabling the axis group before does not change anything, but if I use MC_UngroupAllAxes before changing the controller mode, it all works as it should. Is there no way to control a single axis in torque control, if it is part of an axis group?

Okay, the solution was so simple... In my case, you first have to add the EL1918 and then the EL2904... then the connection is made automatically. I probably had something else before and then added the EL1918... then it doesn't catch the connection :/
