Functional safety Safety function The safety function of SITRANS P DS III with PROFIsafe protocol (ordering option -Z C21) is based on the measurement of pressure. The pressure is converted to a digital measured value and transmitted via PROFIsafe communication. Fault tolerance allowances must be made, because the measured value transferred to the automation system by the transmitter can deviate from the physical value.
