list_device_parameters and set_device_parameter only iterated device.device_parameters and connector.parameters. Host-side parameter sets -- e.g. the WAGO 750-series 'K-BUS Parameters' grid (program start interlock, k-bus cycle time, TCM control) -- are exposed exclusively via ScriptConnector.host_parameters (SP21 stub ScriptDeviceParameters.pyi; helpme-codesys ScriptEngine, ScriptConnector.host_parameters), so both tools reported zero parameters on the Kbus master node. Verified on the Sea Leopard PFC200 project: id 150 'program start interlock' now lists and sets offline.
