Information About 1788-DNBO

The Allen-Bradley 1786-DNBO is a DeviceNet Daughtercard. This daughtercard is used with any compatible Allen-Bradley device that accommodates this module.

For configuration of the DeviceNet daughtercard, RSNetWorx for DeviceNet V3.0 Service Pack 2 is required. This is required to include the module to the system scanlist.

To set the network address of the 1788-DNBO, Two (2) switches are provided with the 1788-DNBO. Valid node address is 0-63 which is the node range supported by DeviceNet networks. As a general rule, the node address of the daughtercard must be unique and shall have no duplicate address in the network. Additionally, setting the node address to 99 and restarting the module, erases the daghtercard to the defined scanlist therefore, this shall only be done is erasure to scanlist is needed. The switch settings are read during powerup to identify the set address and the intended operation for the daughtercard.

The network transmission rate may be configured using a different hardware switch, installed also in the daughtercard. This switch is located beside the Removable connectors and allows setting of speeds such as 125 Kb if set at Zero (0), 250Kb if set at One (1) and 500 Kb if set at Two (2). Similarly, the switch settings are read during module startup.

This daughter card is provided with status indicators such as Network Status (NS) and I/O status indicators. The Network status indicator is a bi-color LED that generally display the status of the communication link. The I/O status indicator as well is a bi-color LED that indicates the I/O scanning speed.

The 1788-DNBO daughter card offers selectable baud rates and nodes (0 = 125k, 1 = 250k, 2 = 500k), which can be set via the hardware push-wheels on the board, and it has input and output data rates of 124 Double Integers (DINT) and 123 DINTs. The 1788-DNBO daughter card connects to the DeviceNet network via a factory provided 5-pin DeviceNet connector cable which is connected to the DeviceNet port on the scanner and screwed tightly with connector screws. It has Network status (NW), module status (MS), and I/O status indicators, which indicate the card’s performance status. The 1788-DNBO daughter card has an operating temperature range of 0 to 60 degrees Celsius, and it can be stored within a –40 to 85 degrees Celsius temperature range. It has a net shipping weight of 0.1 kilograms, and it is CE, c-UR-us, C-TICK, and ODVA certified.

Frequently Asked Questions about 1788-DNBO
Question: What is the purpose of the 1788-DNBO module?
Date Update:19/06/2025
Answer:

The 1788-DNBO is a DeviceNet daughtercard used to enable DeviceNet communication capabilities on compatible host devices. It integrates the host with a DeviceNet network, allowing it to exchange I/O data and status information with other network devices. It acts as a communication bridge between the DeviceNet protocol and the host’s control logic. This module is typically used in systems that require reliable field-level communication in automation architectures. Its compact form makes it ideal for embedded integration.

Question: How is the node address set on the 1788-DNBO?
Date Update:19/06/2025
Answer:

The node address of the 1788-DNBO is set using two rotary switches located on the card. Acceptable addresses range from 0 to 63, which is standard for DeviceNet nodes. Setting the switches to 99 and rebooting erases the scanlist configuration. The address is only read during power-up, so changes require a power cycle to take effect. A unique node address is required for each DeviceNet device on the network to avoid conflicts.

Question: Does the 1788-DNBO have diagnostic indicators?
Date Update:19/06/2025
Answer:

Yes, the module includes several LED indicators: Network Status (NS), Module Status (MS), and I/O Status. These LEDs are bi-color and help indicate the state of communication, configuration, and scanning. For example, a green light typically means normal operation, while red or flashing indicates faults or communication errors. This visual feedback assists technicians during troubleshooting and commissioning. It enhances usability by providing quick system diagnostics.

Question: Which protocols does the 1788-DNBO support?
Date Update:19/06/2025
Answer:

The 1788-DNBO module supports the DeviceNet protocol, which is a widely used fieldbus standard for industrial communication. It allows for real-time I/O messaging and status monitoring across the network. Communication parameters, such as scanlists and device addresses, are configured via RSNetWorx for DeviceNet. The module also supports cyclic and polled I/O data transfer formats. Its compatibility with standard DeviceNet specifications ensures interoperability with Rockwell and third-party devices.

Question: Is the 1788-DNBO still in production?
Date Update:19/06/2025
Answer:

No, the 1788-DNBO was officially discontinued by Rockwell Automation on December 31, 2016. It is no longer available for sale, and Rockwell has not planned any direct RA replacement for this module. Users are encouraged to remove it from their active BOMs and system designs. While some third-party suppliers may still offer surplus stock, long-term support or firmware updates are no longer provided. If you're designing a new system or planning upgrades, consider migrating to newer communication platforms such as EtherNet/IP with supported alternatives.
