  • Page 13 PROFIBUS is an international, open field bus standard which is used widely in the fields of production and process automation. The bus is guaranteed brand-neutral and open by virtue of its compliance with international standards EN 50170 and IEC 61158. PROFIBUS-DP is a PROFIBUS communication profile optimized for high-speed, time-critical data transmission at field level using low-cost connections.
  • Page 14 Criteria such as high transmission speed and simple, low-cost installation are of critical importance in the selection of the transmission system. The RS-485 requires a screened copper cable with twisted-pair wires. The transmission speed can be selected within the 9.6 kbaud to 12 Mbaud range. It is set globally for all devices on the bus during system start-up.
  • Page 15 Data can be exchanged between the higher-level systems (e.g. SIMATIC, SIMADYN D, PC/PGs) and the drives very quickly via the PROFIBUS-DP. Drives are always accessed according to the master-slave principle. Drives are always slave nodes. Each slave can be identified by its unique address on the bus (MAC). All the standards and guidelines listed below can be obtained from the PROFIBUS User Organisation (PNO), www.profibus.com.

  • Page 18 The MICROMASTER4 is controlled via the cyclical PROFIBUS-DP channel. This same channel can be used to exchange parameters. The structure of useful data for the cyclical channel is defined in the PROFIDrive Profile, version 2.0, and referred to as the Parameter Process data Object (PPO). The PROFIDrive Profile defines for the drives the useful data structure with which a master can access the drive slaves using the cyclical data communication method.

  • Page 20 In addition to the PPO types, cyclical data can also be configured optionally. Up to four process data words, with a different number of setpoints and actual values if desired, can be configured on the MICROMASTER4. The areas of consistency can be set flexibly. A parameter area (PKW) can be configured irrespective of the number of process data.
  • Page 21 The reaction time of MICROMASTER4 with respect to PZD is approximately 20 milliseconds. This represents the period of time between "setpoint arrives at DP slave" and "updated (and referencing) actual value is made available on PROFIBUS-DP“. The reaction time of the MICROMASTER4 with respect to a parameter modification (PKW) is approximately 50 milliseconds.
  • Page 22 Acyclical data exchange with a SIMATIC HMI (second class 2 master) The SIMATIC HMI can acyclically access parameters in the converter. Instead of a SIEMENS start-up tool or SIMATIC HMI, an external master (class 2 master) as defined in the acyclical parameter channel according to PROFIDrive Profile version 3.0 (with data block 47) can access the converter.

  • Page 23: Control And Status Words

    The control and status words comply with the specifications for PROFIDrive Profile, version 2.0 or 3.0, for "Closed-loop speed control mode".

  • Page 32 The PROFIBUS connection is on the bottom edge of the board housing. PROFIBUS interface Local 24 V connection Fig. 4-2 PROFIBUS connection on communication board The communication board is normally supplied by the mains supply to the converter. The PROFIBUS communication board has its own separate 24 V supply connection, thereby allowing the communication board and converter electronics to operate independently of the converter mains supply (board is still capable of communicating even when the converter power supply is switched off).

  • Page 33: Maximum Cable Lengths

    The maximum cable lengths are dependent on the baud rate (transmission speed). The maximum cable lengths specified in the table below can be guaranteed only with PROFIBUS bus cables (e.g. Siemens PROFIBUS cable available under order number (MLFB) 6XV1830-0EH10). Table 4-2...

  • Page 34: Bus Connector

    The bus cable must not be twisted stretched or compressed during installation. Supplementary constraints as regards electromagnetic compatibility must also be observed. Further relevant information can be found, for example, in Chapter 3 of the Compendium (6SE7080-0QX50 Edition AE, MASTERDRIVES Docu). To connect the PROFIBUS cable to the communication board, a bus connector of one of the types described in the following table will be required.

  • Page 35: Bus Terminator

    Each bus segment must have a resistor network, i.e. a bus terminator, at both ends. Where the recommended bus connectors have been used, the bus terminator can be switched in and out by means of switches. Terminating resistor Terminating resistor switched in switched in Fig.
  • Page 36 The following EMC-related precautions must be taken to ensure interference-free PROFIBUS-DP operation, particularly in RS-485 data exchange mode: The screen of the PROFIBUS cable must be contacted in the bus connector. Additional screening is provided via a screen clamp on the bus cable screen which must make 360°...

  • Page 43 PROFIBUS slaves have different performance characteristics. To ensure that each slave with its individual properties can be correctly addressed by any master, the characteristic features of a slave are listed in its device master data file (GSD). Device master data file (GSD) The device master data file for the MICROMASTER4 PROFIBUS optional board (SIEM80B5.GSD) is stored on the documentation CD for MICROMASTER4.
  • Page 44 The communication board based on the integrated GSD can utilize the following functions: PPO type 1 or 3 4 PZD for process data Acyclical communication with a SIEMENS start-up tool (e.g. STARTER) and SIMATIC HMI PROFIBUS Optional Board Operating instructions...
  • Page 45 The extended scope of functions includes: Acyclical communication with a SIEMENS start-up tool (e.g. STARTER) and SIMATIC HMI Optional configuration of process data Utilization of internode data communication The MICROMASTER4 with extended functionality is based on an S7-specific configuring software add-on called the "Slave Object Manager".
  • Page 46 The "Internode communication" function is described in detail in PROFIDrive Profile, version 3.0. Internode communication enables slaves to communicate directly with one another instead of routing data indirectly via the DP master. This function can be utilized only in conjunction with a DP master as "synchronizer" or an S7 CPU with "equidistance"...
  • Page 47 You can configure the communication relationships between DP slaves using the internode communication function, e.g.: "Broadcast principle": One master drive specifies a master setpoint for all slave drives. "Peer-to-peer principle": A setpoint is forwarded from one drive to the next. A communication relationship is also referred to as a "channel"...

  • Page 49 You can access a MICROMASTER4 directly using a SIMATIC HMI as the PROFIBUS master. A MICROMASTER4 reacts to a SIMATIC HMI in the same way as it does to a SIMATIC S7. As regards access operations to drive parameters, the following simple formula applies: Parameter number = data block number Parameter subindex = data block offset...

  • Page 50: Diagnostics And Troubleshooting

    You can operate a SIMATIC HMI and a drive together independently of the rest of the automation system. A simple "point-to-point" link with just two nodes is possible. The HMI "Variables" functions can be used for drives. Other functions cannot be used (e.g.
  • Page 51 The MICROMASTER4 can operate only as a standard DP slave on an external master. Required GSD file The device master file (GSD file) contains all information required by a DP master system to integrate the MICROMASTER4 into its PROFIBUS-DP configuration as a standard DP slave.
