1-2 Getting Started
20-COMM-H RS-485 HVAC Adapter User Manual
Publication 20COMM-UM009D-EN-P
Features The adapter features include:
•
Typical mounting in a PowerFlex 7-Class drive using captive screws to
secure and ground the adapter to the drive.
•
Compatibility with various configuration tools to configure the adapter
and connected drive. The tools include the PowerFlex HIM on the drive,
and drive-configuration software such as DriveExplorer (version 2.01 or
higher) or DriveExecutive (version 3.01 or higher).
•
Status indicators that report the status of the drive communications, the
adapter, and network. They are visible when the drive cover is open or
closed.
•
Parameter-configurable I/O (Logic Command/Reference and up to four
pairs of Datalinks) to meet application requirements.
•
User-defined fault actions to determine how the adapter and PowerFlex
drive respond to communication disruptions on the network.
•
Switches to allow setting a node address before applying power to the
drive. Alternatively, you can disable the switches and use a parameter to
configure the node address.
•
A switch lets you select from the following three network protocols:
– Modbus™ RTU
– Metasys™ N2
– Siemens Building Technologies P1 FLN™
•
Available read/write access to parameters, allowing parameter values to
be configured and monitored over the network.
•
Support for DPI routing, enabling access to any networked PowerFlex
7-Class drive (with 20-COMM-H adapter) using DriveExplorer (version
2.01 or higher) to monitor and configure that drive and its connected
peripherals.
Compatible Products DPI is a second generation peripheral communication interface. The adapter
is compatible with Allen-Bradley PowerFlex 7-Class drives and other
products that support DPI. At the time of publication, compatible products
