Description
Product Name: 2706-M1N1 Allen Bradley Processor module
Product details:
The Allen-Bradley 2706-M1N1 is an industrial device, typically identified as a Data Highway Plus (DH+) Interface Module or a Messaging Interface. It belongs to the older Slick 500 family or similar industrial communication architectures from Rockwell Automation (Allen-Bradley).
📋 Product Specifications (Product Parameters)
| Feature | Specification |
| Catalog Number | 2706-M1N1 |
| Type | Messaging Interface Module (or DH+ Interface) |
| Communication Port 1 | DH+ (Data Highway Plus) |
| Communication Port 2 | RS-232 or similar serial port (often used for configuration or connecting to devices like a modem or printer) |
| Function | Allows a device (e.g., a host computer, HMI, or other equipment) to communicate with the DH+ network for monitoring, control, and data exchange. |
| Protocol Support | Data Highway Plus (DH+) |
| Mounting | Typically DIN Rail or Panel Mount |
| Power Supply | Requires external power, typically 24V DC (or similar industrial standard). Specific voltage must be verified against the device’s label. |
⭐ Product Advantages (Product Advantages)
-
Legacy System Integration: The primary advantage is its ability to integrate new or non-DH+ devices into existing Allen-Bradley control systems that utilize the legacy DH+ network. This is crucial for systems that are still reliable but need updated connectivity.
-
Reliable Communication: DH+ is a robust, established industrial network, making the module suitable for critical, high-reliability applications where communication stability is paramount.
-
Data Exchange Capability: It facilitates seamless data exchange (e.g., control messages, alarm data, production statistics) between different levels of the plant hierarchy.
-
Field-Proven Technology: As an older component, it is based on well-understood and field-proven technology, simplifying troubleshooting for experienced maintenance personnel.
⚠️ Important Considerations (Notes/Precautions)
-
Obsolete Status: The 2706-M1N1 is likely obsolete or nearing obsolescence. Finding new spares and factory support may be difficult or expensive. Users should consider a migration strategy to newer Ethernet/IP-based solutions (like ControlLogix/CompactLogix) if long-term support is required.
-
Configuration: Proper configuration of the DH+ node address and communication settings is critical for the device to function correctly on the network.
-
DH+ Wiring: DH+ requires specific shielded cable and grounding practices to maintain signal integrity, which must be strictly followed during installation.
-
Documentation: Always refer to the specific installation and user manual for the 2706-M1N1 for accurate wiring, power, and configuration details.
⚙️ Product Applications (Product Applications)
The 2706-M1N1 is used in industrial environments where data needs to be transferred between a host system and a DH+ network.
-
HMI/SCADA Connectivity: Connecting an external Human-Machine Interface (HMI) or Supervisory Control and Data Acquisition (SCADA) system to the DH+ network to monitor and control Programmable Logic Controllers (PLCs) like the PLC-5 or SLC 5/04.
-
Remote Programming: Allowing a programming workstation to connect to the DH+ network to upload, download, and troubleshoot PLC programs.
-
Data Logging/Reporting: Interfacing a plant-floor computer system for data logging, historian services, and production reporting by extracting information from PLCs on the DH+ network.
-
Modem Communication: In older setups, it could be used to connect a modem to the DH+ network for remote diagnostics or data access.
