Overview
The Allen-Bradley 1784-KTCS Series B is a ControlNet scanner interface card designed to connect personal computers, workstations, and terminals to ControlNet networks in industrial automation environments. This dual-port BNC card operates as both a network interface and a remote I/O scanner, enabling ISA and EISA-compatible computers to communicate seamlessly with Allen-Bradley processors and controllers over ControlNet infrastructure.
Key Features
- Dual-port BNC connectivity — Two independent ControlNet ports for redundant network paths or multi-network configurations
- ISA/EISA compatibility — Installs in 16-bit ISA or 32-bit EISA bus slots on legacy and industrial computers
- Remote I/O scanning — Scans Allen-Bradley remote I/O modules and interfaces with ControlNet devices
- Proven reliability — Engineered for deterministic, time-synchronized industrial networks
- ESD protected — Shipped with grounding wrist strap; CMOS technology requires ESD handling precautions

Typical Applications
The 1784-KTCS is commonly deployed in:
- Real-time monitoring and diagnostics — Engineering workstations monitoring PLC-5 and ControlNet systems
- Remote I/O scanning — Retrieving discrete and analog I/O data from networked scanner modules
- ControlNet network bridging — Interfacing legacy ISA/EISA computers with modern ControlNet infrastructure
- Integrated production lines — Time-synchronized control and data exchange across multiple PLC nodes
- Quality assurance and data logging — Real-time capture of process variables for compliance and SPC applications
Compatibility & Replacements
The 1784-KTCS is part of Allen-Bradley’s legacy ControlNet communication interface family. It works with Allen-Bradley interface software including 6001-F1E, 6200, Interchange, Advisor PC, and ControlView for managing data transmission and reception. The card supports up to four units per computer system, each requiring a unique I/O space and base memory address to avoid conflicts.
For newer systems, users may consider the 1784-KTCX series (PCI-based ControlNet cards) for modern PC platforms. However, the Series B 1784-KTCS remains the standard for retrofitting and maintaining legacy ISA/EISA automation infrastructure with ControlNet connectivity.
