Glossary A Adapter Devices such as drives, controllers, and computers usually require an adapter to provide a communication interface between them and a network. An adapter reads data on the network and transmits it to the connected device. It also reads data in the device and transmits it to the network. The 20-COMM-H RS-485 HVAC adapter connects a PowerFlex 7-Class drive to the network. Adapters are sometimes also called “cards,” “embedded communication options,” “gateways,” “modules,” and “peripherals.
G-2 Glossary DPI Peripheral A device that provides an interface between DPI and a network or user. Peripheral devices are also referred to as “adapters” or “modules.” The 20-COMM-H adapter and PowerFlex 7-Class HIMs (20-HIM-xxx) are examples of DPI peripherals. DPI Product A device that uses the DPI communications interface to communicate with one or more peripheral devices. For example, a motor drive such as a PowerFlex 7-Class drive is a DPI product.
Glossary H G-3 HIM (Human Interface Module) A device that can be used to configure and control a drive. PowerFlex 7-Class HIMs (20-HIM-xxx) can be used to configure PowerFlex 7-Class drives and their connected peripherals. Hold Last When communication is disrupted (for example, a cable is disconnected), the adapter and PowerFlex drive can respond by holding last. Hold last results in the drive receiving the last data received via the network connection before the disruption.
G-4 Glossary Ping A message that is sent by a DPI product to its peripheral devices. They use the ping to gather data about the product, including whether it can receive messages and whether they can log in for control. PowerFlex 7-Class (Architecture Class) Drives The Allen-Bradley PowerFlex 7-Class family of drives supports DPI and includes the PowerFlex 70, PowerFlex 700, PowerFlex 700H, PowerFlex 700S, PowerFlex 700L, and PowerFlex 7000. These drives can be used for applications ranging from 0.
