Post by althafu on Codesys v 3.5 to factory IO ^{CODESYS Forge talk (Post)}
I have been following the steps shown in the RealPars video to connect CODESYS with Factory I/O. The connection works correctly when I use Ladder Diagram, but when I try the same simple input–output logic in Structured Text, the simulation does not behave as expected. Has anyone experienced this issue or knows what might be causing it?

Hi guys, I am experiencing the issue that browser element can't show anything other than wbm of my PLC. I am using WAGO PFC200, trying to feed IP camera into web browser element. Can anyone helps me ? Kind regards, Jin

Hi, you need a realtime capable plc. Codesys Control WinV3 is not realtime capable. https://content.helpme-codesys.com/en/CODESYS%20Control/_rtsl_performance_optimization_linux.html The last chapter of https://content.helpme-codesys.com/en/CODESYS%20SoftMotion/_sm_robotics_diagnosis_movement_problems.html deals with how to configure the planning task.

Go to Online>Communication Parameters...>Gateway>TCP/IP> Click on "New..." and reestablish your connections with whatever IP address and set up information you have. Bypass whatever is necessary as you may have to redownload to the PLC.

Hi, under this circumstances the performance of a Raspberry Pi 4 should be sufficient to run a Softmotion robotics application. A closer look at the project would be required. Maybe you could contact the codesys support? Usually it is recommended to run the planning task cyclically every 2ms with task priority of 0 on a dedicated core. In the task configuration you can have a look at the average and maximum execution time of the planning task. You could use the function block SMC_TuneCPKernel (https://content.helpme-codesys.com/en/libs/SM3_Robotics/Current/SM3_Robotics/POUs/AdministrativeConfiguration/Computation/SMC_TuneCPKernel.html) to define suitable values for the parameters 'fSyncBufferDuration' and 'fPlanningInterval'. However, as previously mentioned, the performance of a Raspberry Pi 4 with realtime patch should be sufficient. The 'fPlanningInterval' parameter specifies the maximum planning step width in seconds. The cycle time of the planning task should not permanently exceed this value. A higher value reduces the computational effort, but can lead to a violation or no full utilization of the set limit values for velocity, acceleration and jerk. From a starting value of 0.016 seconds, the value should be increased gradually until the performance is acceptable. The parameter 'fSyncBufferDuration' specifies the size (in seconds) of the buffer between the planning and fieldbus task. The cycle time of the planning task must not exceed this value at peak times (this will lead to the error SMC_CP_QUEUE_UNDERRUN). A higher value can compensate for peaks in the cycle time of the planning task. At the same time, however, this also increases the latency for executing interrupts and aborting movements.

Post by ofey on two different OPC clients with different privileges ^{CODESYS Forge talk (Post)}
Hi! I have usually only connected one OPC client (our system) to an OPC server created in the codesys environment on a PLC. This OPC client has a lot of write privileges. A customer also want OPC access, but I want to restrict his access to only read certain values. Do you know if this is possible inside the single codesys runtime running on a controller?

Post by plunje on Sensor not set ^{CODESYS Forge talk (Post)}
A got a larger project but this very small example makes it clear. I have a button, and after it's clicked a lamp should flip on and stays on, and when the mouse-button is released it should stay on. When I try that in the PLC_PRG it works, but when I change it to a function block (seet attched demo proj) it isn't. I'm fairly new to PLC programming but are very experienced C# engineer, but this goes above my head...
