EtherNet/IP to DH-485 Gateway
5201-DFNT-DH485
The ProLinx EtherNet/IP to DH-485 Gateway creates a powerful connection between devices on EtherNet/IP and DH-485 networks. This stand-alone DIN-rail mounted protocol gateway provides one Ethernet port and one DH-485 configurable serial port. The ProLinx DH485 protocol driver supports the Master and the Slave modes of the protocol, providing powerful data transfer capability with Rockwell Automation PLCs and HMIs. User configurable data mapping make the interface an easy to use and powerful data transfer tool. The EtherNet/IP protocol driver supports the Explicit Messaging implementation of the protocol. User-configurable as both a Client and a Server, the EtherNet/IP port is a very powerful data transfer tool.

Specifications
Internal Database
The ProLinx module contains an internal database that consists of areas for application data, status information, and configuration information.
The internal database is shared between all ports on the module and is used as a conduit to pass information from a device on one network to one or more devices on another network.
Application Data Area
The data area is used to store and retrieve data by the protocol drivers and for data exchange between protocols. The database is used as a source for write commands to remote devices and holds data collected from the remote devices. Commands defined in the configuration file (stored in the configuration data area) control how the data is to be handled in the database.
Status Data Area
This area is used to store error codes, counters, and port status information for each port.
Configuration Data Area
This area contains module configuration information such as port configuration, network information, and command configuration. This configuration file is downloaded to, or uploaded from, this area.

Protocols
DFNT Protocol Specification
The EtherNet/IP protocol driver supports the Explicit Messaging implementation of the protocol. User-configurable as both a Client and a Server, the EtherNet/IP port is a very powerful data transfer tool.
Protocol Specifications
The EtherNet/IP protocol is one of the primary connectivity tools to the different Rockwell Automation platforms. The Explicit Messaging aspect of the protocol (only) has been implemented in the ProLinx units to provide the data transfer link between the ProLinx units and the Rockwell Automation hardware.
| General Protocol Information |
|
| Messaging |
PCCC on CIP |
| Miscellaneous |
125 word read and write data lengths |
EtherNet/IP Server Specifications
In Server mode, the module accepts commands from one or more clients to read/write data stored in the module's internal registers.
| EtherNet/IP Server Specifications |
|
| Connections | Five independent TCP server sockets permit remote clients to interact with all data contained in the module. |
| Data File |
Data Table File Start - Fixed at N10 |
| CIP Services Supported |
0x4C - CIP Data Table Read |
EtherNet/IP Client Specifications
In Client mode, the module controls the read/write data transfer between the gateway and other EtherNet/IP devices. Data transfer can be initiated and executed without any ladder programming being required in the Rockwell Automation hardware.

DH485 Protocol Specification
The ProLinx DH485 protocol driver supports the Master and the Slave modes of the protocol, providing powerful data transfer capability with Rockwell Automation PLCs and HMIs. User configurable data mapping make the interface an easy to use and powerful data transfer tool.
Protocol Specifications
The DH-485 protocol in its native form is a peer to peer token passing network. The ProLinx DH-485 driver accesses the network functioning either as a Master or as a Slave.
| General Protocol Information |
|
| Error Checking | BCC and CRC |
| Communication Parameters |
Local Station ID: 0 to 31 |
DH-485 Slave Mode
In Slave mode, the module accepts commands from one or more Masters to read/write data stored in the module's internal data memory. In this mode, the ProLinx unit is answering DH-485 commands and has the appearance of an SLC processor to the network.
DH-485 Master Mode
In Master mode, the ProLinx DH-485 driver will actively gather data from other devices on the network, controlling the read/write data transfer between the gateway and other DH-485 devices, such as SLC processors. Data transfer can be initiated and executed with the other devices without any ladder logic being required in the Rockwell Automation slave hardware.
| DH485 Functioning as a Master |
|
| Command List | Up to 100 command per master port, each fully configurable for function, slave address, register to/from addressing and word/bit count |
| Polling of command list | User configurable polling of commands, including disabled, continuous and on change of data (write only) |
