Post by tcarlbom on codesys sp20 opcua not working ^{CODESYS Forge talk (Post)}
hi, anyone else having trouble with opc ua in codesys sp20? i get Error 'BadIdentityTokenInvalid' was returned during ActivateSession i have tried both windows x64 runtime and linux runtime. i have created a completely new codesys project for this. in each of them i have only added the symbol configuration and selected one tag. i have tried several opc ua client, like ua expert, nodejs and python. all return Error 'BadIdentityTokenInvalid' was returned during ActivateSession so the problem must be the opc ua server.

Post by ivanh on kepware minimun privilege ^{CODESYS Forge talk (Post)}
Hello everyone, I’m integrating Codesys with Kepserver using the Kepware driver for Codesys, and I need to configure a user account with the minimum necessary privileges to read and write to the tags on the PLC, without using the internal OPC UA server of Codesys. However, despite not assigning the Modify permission, Kepware still allows writing to the tags. What are the minimum required permissions to ensure that writing is only allowed when necessary, and how can I prevent other permissions from being overridden? Any guidance would be greatly appreciated.

Post by mostafa-beshr on implementing continuous movement in Codesys ^{CODESYS Forge talk (Post)}
Hi everyone, I’m working on implementing continuous movement in Codesys, but I've run into some trouble. I've tried using ALL SM3 Basic and SML without success. I’m specifically looking for a library that supports continuous updates and can fetch values from a server in real time. Does anyone know of a library or approach that fits these requirements? Any advice or suggestions would be greatly appreciated! i read plcopen documentaion as well as codesys Thank you!

What do you mean by continuous movement? You want to continuously follow a dynamic target position? SMC_ControlAxisByPos, which is typically used with CNC Interpolators, could work for that. Instead of feeding the target position in from the Interpolator, feed in the target position from your server instead. Once you enable the FB, it will continuously move the axis to track the fSetPosition input. https://content.helpme-codesys.com/en/libs/SM3_CNC/Current/SM_CNC_POUs/SoftMotion-CNC/Direct-Axis-Control/SMC_ControlAxisByPos.html
