Rockwell Automation Remote I/O to DH-485 Gateway
5601-RIO-DH485
The ProLinx Rockwell Automation Remote I/O Adapter to DH-485 Gateway creates a powerful connection between devices on DH-485 and Remote I/O networks. This stand-alone DIN-rail mounted protocol gateway provides one DH-485 configurable serial port and Remote I/O port.
The RIO interface is an adapter (slave) which can be connected to a scanner (master) that controls the data transfer. The module also supports limited high speed data transfer via the Input and Output images.
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.

Features and Benefits
Applications
The RIO-DH485 modules are the ideal solution for the many applications where DH-485 connectivity can be used to integrate Remote I/O devices into a system. The DH-485 gateway is a powerful module designed with both Master and Slave support, enabling easy connection to Rockwell Automation PLCs (CLX, SLC, PLC, CPLX, and similar devices). In combination with the Remote I/O device support, the module provides a very powerful interface to the many Remote I/O devices which are in use in the industrial marketplace today. Applications for the module are found in most industries, especially the Manufacturing, Oil and Gas, Electrical Power and Food Processing.

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
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) |
RIO Protocol Specification
The RIO interface is an adapter (slave) which can be connected to a scanner (master) that controls the data transfer. The module also supports limited high speed data transfer via the Input and Output images.
Protocol Specifications
The RIO interface is an adapter (slave) and is connected to a scanner (master) that controls the data transfer. For example, the master/slave relationship can be accomplished using the RIO module (adapter/slave unit) with a Rockwell Automation PLC5 (scanner/master unit). Ladder logic must be programmed into a PLC to perform BTR/BTW commands to receive and transmit data between the module and the PLC. The module also supports limited high speed data transfer via the input and output images.
