from rackio import Rackio, TagEngine
from rackio_modbus import RackioModbus

app = Rackio()

# Tags definitions

tag_egine.set_tag("T1", "float")
tag_egine.set_tag("T2", "float")
tag_egine.set_tag("T3", "float")

# Modbus mapping

driver.define_mapping("T1", "write", 0, 60) # Tag, mode, lower limit, upper limit
