Bus coupler

Settings write through the internal register bank with the device's own validation (writes refused while the watchdog is running are rejected with its message).

Save coupler settings

I/O modules

SAVE CONFIG rebuilds the process image (values clear like a KBUS reset; Modbus connections stay open) and writes the node-config YAML.

Channel names

Rename channels for the bench (I/O code → application name). Names show in the overview list and tooltips and persist with the node config.

Import / export
