Post by ofey on Codesys Soft PLC OPC UA server ^{CODESYS Forge talk (Post)}
Hi! I'm sorry if this has been asked before. I have tried looking up previous topics regaring this, but even though I'm following tutorials and other posts I cant seem to get this to work consistently. I actually got the connection established on a test project after some trial and error. I only got it to work with the "Anonymous login". But after i deleted the test project and tried to get the same thing to work on another project I cant get it to work anymore. What I'm trying to do: Set up and OPC UA Server using CODESYS with the free soft PLC. I then try to connect to the OPC UA Server with the program "UaExpert". What happens: I get the error Error "'BadUserAccessDenied' was returned during ActivateSession". What I have done in CODESYS: - Added the object "Symbol configuration" and checked some test variables - Checked "Support OPC UA features - In "Communication settings -> device -> Change runtime security policy" I have checked "Allow anonymous login" What I have done in UAExpert: - Found the OPC UA server under "local". (It is showing two servers though, I do not know why. It showed the same when it worked yesterday). Se attachment - Checked "Anonymous" under "Authentication settings in the OPC UA server. I'm new to CODESYS, so it could be something elementary wrong in my settings. Maybe something in the user settings in CODESYS regarding user rights or something?

Post by cihangur on OpC UA server on Raspberry Pi 64 SL runtime ^{CODESYS Forge talk (Post)}
Hello everyone, I wanted to write here because it is a similar and the most up-to-date topic. I want to connect to CoDeSys Win V3 x64 - 3.5.19.50 with OPC UA using WinCC Advanced V17. (Or to a PLC with CoDeSys Version 4.10.0.0) My settings are exactly the same as the previous comment. I even tried many different settings. I can access all CoDeSys OPC UA variables via TIA Portal IDE and add them to my HMI tags. When WinCC RT Advanced is started, it gives a warning that the connection could not be established and does not update the variables. I can connect to Inovance AM600 using CoDeSys Target version 3.5.11.50. (The same version Win x64 is also connected.) However, a security setting in the current versions prevents me. I would be very happy if those who have up-to-date experience on this issue and find a solution share it. The CoDeSys Security Settings which I can access variables with TIA Portal: CommunicationPolicy: POLICY_BASICSHA256SHA256 CommunicationMode: ALL Activation: Activated UserAuthentication: ENABLED Server Certificate: Valid until 2034 Greetings.

Post by tjacks on Opc UA Data Source Client Browse Error in Codesys HMI ^{CODESYS Forge talk (Post)}
Codesys V3.5 SP21 Patch 3 Codesys HMI 3.5.21.30 I'm trying to connect to an OPC UA server on a Kuka robot controller using Codesys HMI's data source manager. I get through the login phase and the client browses most of the data structure on the server but errors out toward the end with a generic: Error while browsing the client, Failed with service result: BadUnexpectedError. If I complete the data source setup and try to update variables, I get the attached stack trace for the error. I've tried several different endpoint and security options. Most get me through the login but all error out while browsing. UA Expert happily connects and browses with the same configuration. I've connected this same version of Codesys to TwinCAT OPC UA servers and Siemens PLC OPC UA servers. Any ideas on what may be causing the generic BadUnexpectedError during OPC UA server browse?

Post by manuknecht on Maximum dynamic limits of MC_MoveLinearAbsolute and MC_MoveLinearRelative ^{CODESYS Forge talk (Post)}
Hello all I use an axis group with two linear axes in a kinematic system. Using MC_MoveLinearAbsolute and MC_MoveLinearRelative, I am trying to realise dynamic movements (set velocity: 1 m/s, set acceleration: 30 m/s^2) with the highest possible jerk, as I want to compare this with a movement with a trapezoidal velocity profile. However, my measurements show that the axes accelerate with a maximum jerk of approx. 800 m/s^3, even if the value in the function block was set to 10,000 m/s^3. I have already increased the dynamic limits of the two axes accordingly (Velocity: 5000 u/s, Acc-/Deceleration: 250'000 u/s^2, Jerk: 100'000'000 u/s^3, where 1 u = 1 mm), but this had no effect. I have checked the input parameters of the function blocks and the VelFactor, AccFactor and JerkFactor factors are all set to the maximum (value 1). Reducing the cycle time has resulted in a higher jerk, but as we are already working with a cycle time of 1 ms, there is nothing more that can be done here. The axes themselves are still a long way from drawing the maximum current, which is why I assume that this should not be a problem either. Are there other factors or parameters that influence the dynamic limits and therefore allow faster movements? The PLC I am using is a Raspberry Pi 4 and Codesys V3.5 SP20 with all libraries up to date. Thanks in advance Manuel
