  4. 4. What fieldbus is ? Fieldbus  ... an all-digital, bi-directional communication system for field instruments  The fieldbus technology provides in minimum the advantages of programmable, intelligent „HART“-Instruments and additional ... ... continuous monitoring of Multi-Variable-Field instruments in the DCS-System or in the PLC as well as the diagnostic of the instruments  Multi-Variable-Field instruments, e.g. - T-Transmitter: T-Value in E.U. and status signals, ... - P-Transmitter: P-Value in E.U. and status signals, ... - F-Transmitter: F-Value and Quantity-Value and status signals, ... - E-Transmitter: Current and Voltage and Active power and Frequency, ... - Positioner / Actuator: Positioning setpoint and Positioning feedback and End position alarm and Service „on-demand“ status, ...  Multi-drop connection of field instruments (mA-Supply and Data communication)  Real-time performance for control loops and alarm acquisition possible !  The distributed intelligence in the field can now really used with the Fieldbus ABB Automation Products PB_GL_EN, Rev. 04/99 Page 5 1.2 General definitions of a fieldbus
