Product Details
Product Overview
The 1770-KF2 (Part Number 1770-KF2) is a versatile asynchronous communication interface designed to bridge the gap between intelligent RS-232-C or RS-422-A devices and the Allen-Bradley Data Highway (DH) or Data Highway Plus (DH+) networks. This module acts as a protocol converter, allowing minicomputers, industrial terminals, and third-party systems to exchange data with PLC-2, PLC-3, and PLC-5 controllers. It is a standalone unit typically utilized in control room environments for system monitoring and peer-to-peer data synchronization.

Application Scenarios
The 1770-KF2 is frequently deployed in legacy industrial systems where a PC-based HMI or a Unix-based minicomputer requires access to the PLC memory map. It is particularly effective for bridging newer supervisory systems with older 1771-KG or 1775-KA based networks, facilitating phased system upgrades without replacing existing cabling.
Frequently Asked Questions
Q: Can the 1770-KF2 be used as a direct replacement for a 1770-KF3?A: No. While similar, the 1770-KF3 is specifically designed for DH-485 networks, whereas the 1770-KF2 is exclusively for Data Highway and Data Highway Plus networks.
Q: Does this module require internal configuration via jumpers?A: Yes, users must set internal DIP switches and jumpers to define the protocol (DH or DH+), station address, and baud rate for the asynchronous serial link.

Tech & Buying Guide
Strategic Selection: Choosing the Right SCADA Software for Your PLC Project
In industrial automation, the SCADA (Supervisory Control and Data Acquisition) system acts as the bridge between raw machine data and actionable human intelligence. Selecting the incorrect software platform can lead to integration bottlenecks, scalability issues, and excessive long-term maintenance costs. As an automation consultant with 15 years of experience, I have guided many projects through the selection process. Below are the essential criteria for choosing a platform that ensures both performance and longevity.
Ensuring Operational Continuity: The Strategic Value of Redundant Automation Systems
In modern industrial landscapes, unplanned downtime is the ultimate adversary. For sectors relying on complex PLC and DCS architectures, a single hardware failure can trigger catastrophic production losses. Therefore, implementing redundant automation systems is no longer a luxury; it is a fundamental requirement for mission-critical operations. In this article, I analyze why redundancy remains the backbone of reliable industrial infrastructure.
Selecting the Right Cables for Industrial Automation: A Comprehensive Guide
Selecting the appropriate cabling infrastructure is critical for the success of any industrial automation project. Improper cable selection often leads to signal degradation, system instability, and costly downtime. As an automation engineer, I frequently see projects compromised by poor cabling choices in harsh industrial environments. This guide simplifies the complex landscape of cabling to help you make informed decisions for your PLC, DCS, and control systems.
