Overview of Allen-Bradley 1756-DHRIO

The Allen-Bradley 1756-DHRIO module is designed to facilitate communication for the ControlLogix system. It enables users to connect their ControlLogix processor to DH+/RIO networks, effectively linking it to a range of devices using Data Highway Plus (DH+) and Remote I/O (RIO) communication protocols. This module is an integral part of many industrial automation systems that require a robust and reliable means for data exchange between different parts of the system.

Features of the 1756-DHRIO Module

The 1756-DHRIO module boasts several key features that make it suitable for use in an industrial setting. It has two independent ports that can be configured for either DH+ or RIO communication, allowing it to serve multiple networks simultaneously. The communication rate for DH+ is up to 230.4 Kbps, while for RIO, it supports rates depending on the topology of the network. Additionally, this module provides bridge functionality, enabling seamless messaging between DH+ and RIO networks.

Configurability and Installation

Configuring the 1756-DHRIO is straightforward, using RSLogix 5000 programming software. During setup, users can specify the communication protocol for each port, as well as other network parameters such as baud rate and network address. Installation of the module into a ControlLogix chassis is equally simple, as it uses a backplane interface for power and network connectivity, making the integration process quick and efficient.

Applications of the 1756-DHRIO

The 1756-DHRIO module finds extensive use in various industrial applications, such as manufacturing, automotive assembly, and material handling. It is particularly useful in facilities where legacy equipment requiring DH+ or RIO communication is present. By providing a means to connect these older systems with modern ControlLogix platforms, the 1756-DHRIO opens up new possibilities for system upgrades and integration, without the need for a complete overhaul of existing infrastructure.
