Application example
The application Zelio check the temperature. The controller Twido transmit the temperature set
point (threshold) to Zelio via the fieldbus modbus. The measure of temperature is wiring on the
Zelio analogue input. If the temperature is higher than the threshold, an alarm is activate
(Klaxon).
Twido (master) manages the
Modbus exchanges which are
transparent for Zelio Logic.
