This avoids stubs, and the bus connector can be connected to the bus or disconnected from the bus at any time without interrupting data traffic. These connectors include a bus termination that can be switched in or out.

    PROFIBUS DP overview PROFIBUS Overview PROFIBUS was developed as an open fieldbus. It was standardized in the German standard DIN 19 245 and was later incorporated in the European standard EN 50 170, Vol. 2. PROFIBUS is a medium for pure data transfer, like the RS232 standard for instance.
  • Page 12 PROFIBUS DP overview PROFIBUS DP data transfer The master always transfers the same number of data bytes with each of its slaves in turn (always around a loop), thereby always keeping the total transfer time constant. Each slave must respond within a fixed time slot. Theoretically, 240 bytes are possible in each response.

  • Page 36: Appendix A: Representation Of Floating-Point Values

    Appendix Appendix A: Representation of floating-point values Floating-point numbers from measurement results are transferred as 4-byte float values as specified in IEEE-754-1985. The following examples explain how the 4 bytes are interpreted in order to obtain the floating-point values. What components make up a float number? A floating-point number represented as a 4-byte float value consists of three elements: the sign bit (sign), the exponent (ex) and the mantissa (mant).
  • Page 37 Appendix x = -0,25 is represented as -1.0 * 2 , i.e. sign bit (sign): 1 (negative) exponent (ex): 125 – 127 = -2 mantissa (mant): 0.0 + 1.0 = 1.0 giving: − − − − − − − Encoding of the three formula components in the four bytes 1st byte (first byte) Bit 7 Bit 6...
  • Page 38 Appendix The following 4 bytes were received: (Byte 1) (Byte 2) (Byte 3) (Byte 4) (first byte received) (last byte received) 0x3F 0x40 0x00 0x00 0011 1111b 0100 0000b 0000 0000b 0000 0000b 011 1111 100 0000 0000 0000 0000 0000b E=0111 1110b M=100 0000 0000 0000 0000 0000b E=0x7E (dec.126)
  • Page 39 Appendix Calculation tip This calculation can be performed relatively easily by bit manipulation directly at the binary level using the following sequence of operations: First, as described above, the three components of sign bit, exponent and mantissa must be obtained from the four bytes by copying and masking bits. Example: As described above, the bytes 0x3F,0x40,0x00,0x00 become...

  • Page 40: Appendix B: Byte Sequence Of Float Values

    Appendix Appendix B: Byte sequence of float values In the DIGIFORCE 9310, one can reverse the order of the 4 bytes making up a float number as specified in IEEE-754 by breaking and resoldering solder bridges on the PROFIBUS board. Normally this is not necessary; however there are PROFIBUS masters whose conversion routine expects a different sequence.
  • Page 41 Appendix (1) Remove all connectors from the unit. Disconnect the unit from the power supply. (2) Use a TORX screwdriver (size 02) to undo the four screws on the rear of the unit. (3) Pull out the rear panel together with all four circuit boards from the unit. (4) Undo the two Phillips screws holding the PROFIBUS board in place.
