Alarm Handling In Loop-powered Field Device
7 Sep 23
A field device comprising measurement circuitry; loop current circuitry; voltage measurement circuitry; and a controller configured to: acquire a first value of a process variable; determine if the voltage received by the field device is sufficient to support a first loop current; control, when the voltage is insufficient to support the first loop current, the loop current to an alarm current lower than a predefined alarm threshold current; acquire a second value of the process variable and a present voltage received by the field device; determine a second loop current; determine, based on the present voltage and an estimation of a loop impedance, whether or not the present voltage is sufficient for supporting the second loop current; and control, when it is determined that the present voltage received by the field device from the current loop is sufficient, the loop current from the alarm current to the second loop current.
