Hi, how should that work? You need to download the example project and you need that structure of the project and one of the additional hardware sets https://forge.codesys.com/drv/sm3raspistepper/home/Home/ L298N or A4988, DRV8880. Important to have no GPIO in the project and have this additional tasks.

Extending Beckhoff’s dynamic config examples can get tricky fast, especially when oversampling and timestamping are involved. If you’ve been debugging this for two days, it might be worth double-checking the PDO mapping and whether the EL3632 is correctly switching to the expected oversampling mode after detection. Those modules can behave differently depending on firmware and sync settings. Sharing a bit more about where the configuration breaks (state transition, PDO assignment, or data readout) might help others point you in the right direction. https://forge.codesys.com/forge/talk/Engineering/thread/e42a7575e1

You're using dynamic EtherCAT configuration for EL3632 (analog input, timestamped, oversampling). You're correctly detecting the slave and setting DC settings, SMs, and FMMUs manually. You're getting a PLL error. You're missing a startup parameter: 0x10F3:0x05 = Command_0, Value = 0 You're using autoconfigure mode for the master. The input memory alignment differs between manual (dynamic) config and TwinCAT's static config. https://forge.codesys.com/forge/talk/Engineering/thread/e42a7575e1/[snow rider 3d]

Hi, once in a while I get an Access Violation exception in Sherd memory pointer. the strange thing is that I protect the pointer dereference and I get this exception 1 line after the protection. I added photos of the exception can someone tell me what is that about?
