Description
Product Name: 1770-KF2 Allen Bradley Programmable controller
Product details:
The 1770-KF2 is a Data Highway/Data Highway Plus (DH/DH+) Interface Module.
-
Function: It converts the proprietary DH/DH+ protocol into the standard ASCII or binary (BIN) format used by asynchronous serial devices (like PCs, operator terminals, or printers).
-
Role: It allows a non-Allen-Bradley device to communicate with and access data from PLCs (like PLC-5 or older SLC-500 models) on a DH or DH+ network.
-
Physical Interface: It provides a standard RS-232-C port for connection to the host computer/terminal.
⚙️ Product Specifications (产品参数)
Based on typical specifications for this type of module:
| Parameter | Specification |
| Module Type | Communication Interface |
| Network Compatibility | Data Highway (DH) or Data Highway Plus (DH+) |
| Serial Port | RS-232-C (Asynchronous) |
| DH/DH+ Communication Speed | Up to $57.6 \text{ kbps}$ (typical for DH/DH+) |
| Asynchronous Serial Speed | Configurable, typically $110$ to $9600 \text{ bps}$ |
| Power Supply | Typically $115/230 \text{ VAC}$ |
| Current Draw | Approx. $0.3 \text{ A}$ at $115/230 \text{ VAC}$ |
| Operating Temperature | $0^\circ \text{C}$ to $45^\circ \text{C}$ ($32^\circ \text{F}$ to $113^\circ \text{F}$) |
| Humidity | $10\%$ to $80\%$ Non-Condensing |
✨ Product Advantages (产品优势)
-
Legacy Connectivity: Provides a crucial link between older, robust Allen-Bradley DH/DH+ networks and modern or non-proprietary systems (e.g., standard PC running an HMI or SCADA software).
-
Non-Proprietary Interface: Uses the universally supported RS-232-C protocol, making it easy to integrate with various serial devices.
-
Protocol Conversion: Handles the complex protocol translation from the DH/DH+ protocol to simple ASCII/BIN, offloading this task from the host computer.
-
Cost-Effective Diagnostics: Allows standard PCs or terminals to be used for basic programming, monitoring, and diagnostics of PLCs on the DH/DH+ network without requiring a dedicated Allen-Bradley interface card.
⚠️ Important Considerations (注意事项)
-
Obsolete Status: The 1770-KF2 is an older, obsolete product. Support and new units may be difficult to find. Replacement parts are usually sourced from surplus or used markets.
-
Speed Limitation: The serial communication speed is relatively slow (up to $9600 \text{ bps}$), which can be a bottleneck for high-speed data transfer or large-volume data logging.
-
Configuration Complexity: Setting up the DH/DH+ node address, baud rates, and parity settings for both the DH/DH+ side and the serial side requires careful configuration.
-
Driver/Software Dependency: The host computer requires specific software drivers or applications that know how to format the ASCII/BIN messages according to the 1770-KF2’s required message structure.
🌍 Product Applications (产品应用)
The 1770-KF2 is typically used in industrial automation environments for:
-
HMI/SCADA Connectivity: Connecting an external Human-Machine Interface (HMI) or Supervisory Control and Data Acquisition (SCADA) system running on a standard PC to the DH/DH+ network for visualization and control.
-
Data Logging: Allowing a computer to collect process data and log variables from PLCs connected to the DH/DH+ network.
-
Basic Programming/Diagnostics: Providing a cost-effective connection point for technicians to perform simple programming, monitoring, or troubleshooting tasks using a laptop with appropriate software.
-
Printer Interface: Connecting a serial printer to log alarms, events, or production reports from the PLC.
