    Appendix Adapter Parameters Appendix B provides information about the PROFIBUS adapter parameters. Topic Page About Parameter Numbers B-1 Parameter List About Parameter Numbers The parameters in the adapter are numbered consecutively. However, depending on which configuration tool you use, they may have different numbers.

    “cards,” “embedded communication options,” “gateways,” “modules,” and “peripherals.” ControlFLASH ControlFLASH is an Allen-Bradley software tool that lets users electronically update firmware on printed circuit boards. The tool takes advantage of the growing use of flash memory (electronic erasable chips) across industrial control products.
  • Page 106 The drive determines the size of Datalinks. DPI is a second generation peripheral communication interface used by various Allen-Bradley drives and power products. It is a functional enhancement to SCANport. DriveExplorer Software DriveExplorer software is a tool for monitoring and configuring Allen-Bradley products and adapters.
  • Page 107 Glossary-3 Fault Configuration When communications are disrupted (for example, a cable is disconnected), the adapter and PowerFlex drive can respond with a user-defined fault configuration. The user sets the data that is sent to the drive in the fault configuration parameters (Parameters 13 - [Flt Cfg Logic] through 22 - [Flt Cfg D2]).
  • Page 108 Glossary-4 I/O Data I/O transmit time-critical data such as a Logic Command and Reference. The terms “input” and “output” are defined from the scanner’s point of view. Output is transmitted by the scanner and consumed by the adapter. Input is transmitted by the adapter and consumed by the scanner. Logic Command/Logic Status The Logic Command is used to control the PowerFlex drive (e.g., start, stop, direction).
  • Page 109 Glossary-5 PowerFlex Drives The Allen-Bradley PowerFlex family of drives includes PowerFlex 70, PowerFlex 700, and PowerFlex 7000 drives. These drives can be used for applications ranging from 0.37 kW (0.5 HP) to 3,000 kW (4,000 HP). All PowerFlex drives implement DPI, allowing them to use the 20-COMM-P PROFIBUS adapter.
  • Page 110 Glossary-6 Zero Data When communications are disrupted (for example, a cable is disconnected), the adapter and drive can respond with zero data. Zero data results in the drive receiving zero as values for command data. If the drive was running and using the Reference from the adapter, it will stay running but at zero Reference.
