  • Page 15: The Profibus-Dp Interface

    The PROFIBUS-DP Interface The PROFIBUS-DP Interface PROFIBUS-DP (Decentralized Periphery) is the speed-optimized PROFIBUS option designed in par- ticular for fast data exchange at the sensor/actuator level. DP is used by central automation sys- tems (e.g. programmable logic controllers) to communicate with decentralized peripherals such as sensors and actuators, among them drive inverters, via a fast serial link.
  • Page 16 The PROFIBUS-DP Interface ® handled by the bus system. For example, position values of the MOVIDRIVE drive inverter should be transferred in a consistent manner, i.e. it has to be ensured that contiguous data are also trans- ferred together and not, for example, that the least significant part of the position is transferred one bus cycle ahead of the more significant part.

Identifier byte 1 contains the code for the parameter channel, identifier byte 2 contains the code for 1 (2, 3) process data word(s).

  • Page 19: Ident Number

    The PROFIBUS-DP Interface Ident Number Each DP master and DP slave must have an individual identification number assigned to them by the PROFIBUS User Group so that the units connected to the bus can be uniquely identified. When the PROFIBUS-DP master is started, it compares the Ident Numbers of the connected DP slaves with those specified by the user.

  • Page 20: Diagnostic Data

  • Page 26: Parameter Adjustment Via Profibus-Dp

    The PROFIBUS-DP Interface Parameter adjustment via PROFIBUS-DP In the case of PROFIBUS-DP, access to the drive parameters is via the MOVILINK parameter chan- nel which, in addition to the standard READ and WRITE services, offers a variety of other parame- ter services.
  • Page 27 The PROFIBUS-DP Interface 3.7.1.1 Management of the Parameter Channel The entire parameter adjustment procedure is co-ordinated using byte 0: Management. This byte makes important parameters, such as Service Identifier, data length, version and status, of the exe- cuted service available. Fig. 25 shows that bits 0, 1, 2 and 3 contain the service identifier, in other words, they define which service is to be executed.
  • Page 28 The PROFIBUS-DP Interface 3.7.1.3 Data Area As shown in Fig. 26 the data are contained in byte 4 to byte 7 of the parameter channel. This allows a maximum of 4-byte data to be transferred per each service. The data are generally entered flush right, i.e.

  • Page 29: Reading A Parameter Via Profibus-Dp (Read)

    The PROFIBUS-DP Interface 3.7.2 Reading a Parameter via PROFIBUS-DP (Read) When executing a READ service via the parameter channel, the handshake bit should not be tog- gled until the entire parameter channel has been set up accordingly for the service in question, as the parameter channel is transferred on a cyclic basis.

  • Page 30: Writing A Parameter Via Profibus-Dp (Write)

    The PROFIBUS-DP Interface 3.7.3 Writing a Parameter via PROFIBUS-DP (Write) When executing a WRITE service via the parameter channel, the handshake bit should not be tog- gled until the entire parameter channel has been set up accordingly for the service in question, as the parameter channel is transferred on a cyclic basis.

  • Page 31: Sequence Of Parameter Adjustment Via Profibus-Dp

    The PROFIBUS-DP Interface 3.7.4 Sequence of Parameter Adjustment via PROFIBUS-DP Using the WRITE service as an example, Fig. 30 shows the sequence of parameter adjustment between control system and drive inverter on PROFIBUS-DP. To simplify the sequence, only the management byte of the parameter channel is shown in Fig. 30. While the control system sets up the parameter channel for the Write service, the drive inverter simply receives and returns the parameter channel.

  • Page 42: Movilink Acyclic Parameter Channel" Object

    The PROFIBUS-FMS Interface ® Fig. 42 shows the sequence of parameter access via the cyclic MOVILINK parameter channel. The inverter will only start executing the service when the master has toggled the handshake bit in the parameter channel. To do this, the master has to read the parameter channel at the beginning of the parameter adjustment in order to maintain the present status of the handshake bit in the inverter.
  • Page 43 The PROFIBUS-FMS Interface ® When the drive inverter is parameterized via the acyclic MOVILINK parameter channel, a distinc- tion is made between the following two operations: 1) Parameter channel executes a Write service. 2) Parameter channel executes a Read service. 1) Parameter channel executes a Write service If a Write service is executed via the acyclic parameter channel (e.g.
