1 PROFIBUS Basics PROFIBUS Network Overview • PROFIBUS is an open, vendor independent FieldBus standard for a wide range of applications in industrial automation, including motion control. PROFIBUS is a dynamic technology that grows functionally while complying with the European FieldBus Standard EN 50 170. PROFIBUS Guidelines and Profiles provide the means for further technical development based on the ever-changing communication requirements of the networks, systems, and d

2 Connecting the Slave to the PROFIBUS Network Network Segment Length A PROFIBUS network uses either fiber optic or RS-485 copper media. The copper bus line specified in EN 50 170 is “Line Type A” and is the recommended cable type. A more economical copper cable “Line Type B” is commonly used for smaller installations; however, it is not specified in EN 50 170. It is extremely important to use cable rated to PROFIBUS specifications. The higher the baud rate selected and the longer

2 PROFIBUS Cable Types The recommended cable is Belden 3079A PROFIBUS Cable This is a shielded, 150 ohm twinaxial (single twisted pair) cable. It has 22 AWG conductors and a mutual capacitance of 9.0 pF per foot, nominal. For complete specifications on this cable, please contact your Belden dealer or visit their website at www.belden.com. Alternate cable types are: Siemens 6XV1 830-OAH10 Two Core shielded Siemens 6XV1 830-OBH10 w/PE Sheath Siemens 6XV1 830-3AH10 for u

2 Note: For proper network termination, it is essential that the terminating devices maintain power. Power is provided by the device on Pin 6 and Ground on Pin 5. If power is lost to either terminating device, the network may not operate correctly. Generally, the lone network master device is one of the terminating devices. Therefore, a loss of power to the network master renders the network inoperable anyway. The other terminating device may be a critical slave device, which must

3 Configuring a PROFIBUS Slave Module The PROFIBUS Slave module has four Parameters tabs: Settings, Input Data Area, Output Data Area, and Power Consumption. Settings Tab Station The Slave module’s station number that is used on the PROFIBUS network. Can be in the range from 1 to 125. Each module on a network should be given a unique station number. Default is 1. Note that the Master is commonly assigned to Station 0 (zero). Baud Rate Specifies the data transmission rate for th

3 Input Data Area Tab The input data area describes data received over the network by the Slave module from the PROFIBUS Master. These inputs are mapped, using the Input Data Area tab, into specific memory locations in the PLC where the Slave module resides. PROFIBUS Slave Module’s Input Data Area Parameters Area A read-only identifier for the row. Valid range: 1 to 32. Type Data type of area being defined. Valid types are Digital In, Analog In, and Empty. The default value is E

4 Communication Requests The Communications Request uses the parameters of the COMMREQ Ladder Instruction and an associated Command Block to define the characteristics of the request. An associated Status Word reports the results of each request. The Communication Request function (COMMREQ) allows the program to communicate with a GE Fanuc intelligent module, such as a PROFIBUS slave module. The COMMREQ function uses a command block that contains the data to be communicated to the
