Unit of ramp slope in °C per time unit, or format of segment times
for program controller/generator.

0=off
For a program controller/generator and ramp function, the
process value can be monitored by applying a tolerance band
around the setpoint profile.
If the upper or lower limit is infringed, a tolerance limit signal is
generated, which is internally processed or produced via an
output.
Example:
Signal is produced when
process value is 20 °C
larger or smaller than
setpoint.
toLP=40
Processing the tolerance
limit signal, see:
