# Example FAT scenario for a pump-station PLC program.
#
# With a REAL PLC under test: run `wago-sim serve` against this node
# configuration; the PLC drives the outputs and the scenario asserts on
# them. Remove the `plugins:` line below — the PLC is the plant.
#
# Headless (no PLC): the plugins line loads an emulated plant model so
# the scenario can be smoke-tested end-to-end before the FAT bench is
# wired.
