Ramp
The Ramp function block is typically used for variable speed, valve position, and chemical feed control
applications to reduce the output value as more external devices are enabled.
For example, if one pump is running at 100 % and a second pump is enabled, the output value may be re-
scaled to 50 % by the pump 2 enable signal.
The ramp block references an analog signal, and using four separate scales multiplexed together, provides a
single analog output over a programmed range.
