DH485 ROUTER
A-DH485R
Note: This product has been replaced by the DH485 Series Router - A-DH485/B
The DH485 Router provides intelligent data routing between EtherNet/IP and DH485 which can help simplify the migration from PLC5, and SLC systems to ControlLogix or CompactLogix platforms, where a DH485 interface is required.
- Intelligent routing to Logix/SLC/MicroLogix
- Direct-to-Tag Technology
- Supports PLC5/SLC mapping
- Supports Logix programming over Ethernet for Serial interfaces (SLC/MicroLogix)
- Supports interfacing of PanelView Plus and PV800 terminals from Ethernet to Serial
- Can be used to replace the 1761-NET-AIC
- RS485 port
- Redundancy supported
Overview
DH485 Router Modes
The DH485 Router is able to transfer data from a DH485 device to a maximum of three Logix controllers. The module operates in one of four modes, simplifying the configuration for all applications.
| Mode | Description | Message Initiator |
| Transparent PCCC | The DH485 Router will redirect DF1 PCCC messages to a Logix controller at a preconfigured EtherNet/IP path. Logix PLC Mapping configuration is also required. | Remote Device |
| Reactive Tag | The DH485Router will convert DF1 PCCC messages to Logix controller tag reads or tag writes. No Logix PLC Mapping configuration is required. | Remote Device |
| Scheduled Tag | The DH485 Router transfers data between a DH485 device and a number of Logix tags, using a preconfigured scheduled. No Logix or remote device configuration is required. | DH485 Router |
| Unscheduled | The DH485 Router transfers messages received from a Logix Message Instruction. | Logix (Msg) |
Free Configuration Software
The DH485 Router is configured using the Aparian Slate application. Slate offers various configuration methods, including a controller tag browser.
Add to IO Tree in RSLogix
The module can operate in both a Logix “owned” and standalone mode. With a Logix connection the input and output assemblies will provide additional diagnostics information which will be available in the Logix controller environment.
1761-NET-AIC Replacement
The DH485 Router can be used as a replacement for the 1761-NET-AIC. The router converts DH485 to EtherNet/IP directly so a DF1 is no longer required.
Simple Installation
The module uses RS485 for DH485 communication. The RS485 port also uses a terminal block for convenient installation.
Status & Diagnostics
A built-in webserver provides detailed diagnostics of system configuration and operation, including the display of received DH485 communication packets, without the need for any additional software.
Application
Example of a typical network setup:
