    Instruction Manual Technical Description PROFIBUS The PROFIBUS (Process Field Bus) is an open communication system for automation engineering which is being used in its thousands all over the world and which is specified in the European standard EN 50170. 1.1.1 General Information about PROFIBUS DP and PA The PROFIBUS PA is a variant of the PROFIBUS DP which is used widely in production engineering.

  • Page 5: Properties Of The Profibus Pa

    Instruction Manual 1.1.2 Properties of the PROFIBUS PA The PROFIBUS PA (PA = Process Automation) enables di-directional communication between a bus master and the field devices over a two-wire cable. At the same time the power is supplied to the two-wire field devices through the same cables (current I in Figure 1--1).

    Instruction Manual Warning Only certified supply units (DP/PA couplers or DP/PA links) may be used to feed the intrinsically safe PROFIBUS. See the EC Type Examination Certificate for requirements. The number of devices which can be connected to a bus line is given by the total of maximum current consumptions of the connected devices (³...

    Instruction Manual Operation, Communication PROFIBUS Communication SITRANS F has a PROFIBUS PA connection corresponding with IEC 1158 (synchronous transmission). The only possible baud rate is 31.25 kbits/s. The min T (smallest station delay time, chapter 5.4.1, Seite 32) at startup is 11 bit times and can subsequently be changed using the Set_Prm service. The bus address has the value 126 as-delivered and can either be changed with the Set_Slave_Add DP service or on the local keyboard (menu 4.1.1).

  • Page 20: Local Operation And Display

    Instruction Manual Local Operation and Display The menu structure for local operation is mostly repeated in the SIMATIC PDM PC user interface. It is based on the block structure which is a mandatory setting from the PROFIBUS PA profile. Substantial differences from the menu structure of the device with HART communication therefore cannot be avoided.

  • Page 27: Locking Operation

    Instruction Manual The display limits the input of numerical values with local operation to the value range --10 to + 10 . With PROFIBUS the range of values is in principle extended to --10 to + 10 . This is only reached in extreme cases with totalizer readings when the value 999 999 999 then appears in the display.

    Instruction Manual Hardware Write Protection: If write protection with hardware components is not set, the HW_WRITE_PROTECTION PROFIBUS parameter will not be of any significance.

    Instruction Manual 5.3.2 Totalizer (menu 3.5...3.7) The totalizers have fixed counting direction settings. The counting direction cannot be changed. The totalizers directly accumulate the physical measured values according to the negative or positive sign, i.e. the reverse totalizer only accepts negative values. The reading of the net totalizer is cumulated from the flow values with the correct sign and is not calculated from the difference of the contents of the forward and reverse totalizer.
