    These components are deemed "well-tried components" and are listed in ISO 13849-2, Annexes A through D. Additionally, components that have been tested by the manufacturer and approved according to the relevant component safety standard, e.g., IEC 60947-5-5, are also considered well-tried. Since Category 1 is single channel, DC avg = NONE. CCF ...

    The Remote Terminal Unit is initially interrogated with what DNP3 terms an "Integrity Poll" (a combined Read of Class 1, 2, 3 and 0 data). This causes the Remote Terminal Unit to send all buffered events and also all static point data to the Master station. Following this, the Master polls for the event data by reading Class 1, Class 2 or Class 3.
