DL2000-KFR:
DH+ or RIO to Df1 Protocols


 
The DL2000-KFR is a compact, freestanding, serial interface to Allen-Bradley industrial networks. This unit contains two network protocols, software configurable for either A-B Data Highway Plus (DH+) or Remote I/O Link (RIO) networks. In RIO mode the DataLink connects any serial device capable of A-B serial DF1 (Standard DF1) protocol to A-B's RIO Link. DH+ mode connects any serial device capable of Standard DF1 protocol to A-B's DH+.

DL2000 User's Guide.
DL2000-KFR Application Notes.

When the DL2000-KFR is configured for RIO mode the network interface of the DataLink looks like an adapter (virtual rack) to a PLC scanner controlling the RIO Link. The serial interface of the DataLink responds to DF1 protocol commands initiated by devices such as PCs, computers and OEM equipment. Applications for this unit include Operator Interfaces (HMIs), SCADA, Data Acquisition, Variable Speed Drives and Process Control equipment.

Compact and Lightweight:
Size 7.5" x 5.5" x 1.5"; Weight 2.2 lbs

Flexible Serial Interfacing:
RS232C and RS422/RS485

Easy Configuration:
All parameters are menu-driven

Dual Protocols:
DH+ and RIO adapter modes

DH+ Mode:
Alternative to A-B 1770-KF2

DH+ Speeds:
57.6 Kb and 115.2 Kb

RIO Mode:
RIO speeds 57.6, 115.2 and 230.4 Kb, the unit can be configured as any valid rack number and can be set to cover a 7-rack address range to increase block transfer capability. An HMI can read all RIO image table data, write up to 128 bits, and read / write a total of 32 data blocks per rack (maximum of 64 words each).

Communications:
A-B Serial DF1 interface to 57.6 Kbaud
