Allen-Bradley 1788-CNC
ControlNet Daughtercard
Product Overview 01 / FUNCTION
The 1788-CNC is an Allen-Bradley ControlNet daughtercard. It is installed in a compatible host device rather than used as a standalone controller.
On a ControlNet network, a supported 1788-CNC can store network parameters and act as a network keeper. Multiple capable devices can provide automatic backup of the current keeper.
Product Identification
Manufacturer: Allen-Bradley / Rockwell Automation
Catalog Number: 1788-CNC
Product Type: ControlNet Daughtercard
Network: ControlNet
Technical Specifications 02 / DATA
The following values are taken from Rockwell Automation publication 1788-IN002C-EN-P. Specifications shown are for 1788-CNC where the manual distinguishes it from 1788-CNCR.

Host Compatibility & Network Role 03 / SYSTEM
Host Device Requirement
The 1788-CNC can be installed in a host device designed to support the ControlNet daughtercard option. The host must also provide a suitable power source within the published restrictions.
The installation method and host-specific performance depend on the particular host device. Consult that host's user manual before installation.
ControlNet Keeper Function
A ControlNet network requires at least one device capable of storing network parameters and configuring the network at startup. A 1788-CNC can perform this keeper role.
Other capable devices on the same network can automatically back up the current keeper.
Installation & Network Connection 04 / FIELD
Installation Notes
- Follow the installation instructions for the specific host device.
- Do not install or remove the daughtercard while the host is powered.
- Use appropriate electrostatic-discharge precautions when handling the card.
- Because the product is open-style equipment, install it inside a suitable enclosure.
ControlNet Cabling
- Connect the card to the network through an approved ControlNet tap.
- For a non-redundant cable system, use channel A.
- For direct network installation, refer to the ControlNet tap and coax media installation documentation.
- The NAP port is intended for temporary local programming, not permanent connection.
Status Indicators & Troubleshooting 05 / DIAGNOSTICS
Module Status Indicator
- Off: Check host power, host fault state and daughtercard seating.
- Steady red: Indicates a major hardware fault.
- Flashing red: Possible minor fault, firmware update, changed node-address switch, invalid firmware or duplicate node address.
- Flashing green: No connections established.
- Steady green: Connections established.
Network Status Indicators
- Steady green: Normal operation.
- Flashing red/off: Check coax media, connectors and terminators for a media fault.
- Alternating red/off: Check the node address and ControlNet configuration.
- Flashing red/green: Possible incorrect network configuration.
Application & Fault Scenarios 06 / OPERATIONS
Where It Is Used
The 1788-CNC is used in compatible host equipment that requires a ControlNet network interface. It supports communication between the host device and a ControlNet network and can provide the network keeper function.
Why Customers Search for This Part
Maintenance teams may source this daughtercard when a host device loses its ControlNet connection, reports a daughtercard hardware fault, or cannot establish the expected network communication.
If the affected host is part of a production control or communications path, the interruption may prevent connected control equipment from exchanging required data and can contribute to production downtime.
Manufacturer Documentation 07 / REFERENCES
