Description
Product Name: 1789-L30 Allen Braley Input module
Product details:
The Allen-Bradley 1789-L30 is a specialized controller from the SoftLogix 5800 family. Unlike traditional hardware-based PLCs (Programmable Logic Controllers), the 1789-L30 is a chassis-less, software-based controller designed to run on a standard industrial PC (IPC) with a Windows operating system.
Product Overview
The SoftLogix 5800 controller provides a high-performance control engine that combines the capabilities of a Logix5000 controller with the flexibility of a PC. It is ideal for applications requiring heavy data processing, high-speed communication, and integration with third-party PC software.

Key Advantages
-
PC Integration: Allows seamless integration with other PC applications like HMI, databases (SQL), and custom C++ or Visual Basic programs on the same hardware.
-
High Performance: Leverages the processing power of modern PC CPUs, which often exceed the speeds of dedicated hardware PLCs for complex math or data-heavy tasks.
-
Cost-Effective for Large Systems: Since it does not require a physical chassis or dedicated power supply for the controller itself, it can reduce hardware footprint in specific setups.
-
Familiar Programming: Uses Studio 5000 Logix Designer (formerly RSLogix 5000), meaning programmers familiar with ControlLogix can use it without a new learning curve.
Important Considerations (Precautions)
-
OS Stability: Since the controller runs on Windows, the stability of the control system is dependent on the stability of the PC and the operating system.
-
Deterministic Control: To ensure real-time performance, it is highly recommended to use a dedicated Network Interface Card (NIC) for I/O control to avoid Windows-related latency.
-
Hardware Requirements: Ensure the industrial PC meets the minimum RAM and processor requirements specified by Rockwell Automation to prevent “watchdog” timeouts.
-
Shutdown Procedures: Sudden power loss to the PC can lead to file corruption. An Uninterruptible Power Supply (UPS) is strongly recommended.
Product Applications
-
Data Intensive Operations: Applications requiring complex calculations, large historical data storage, or complex recipe management.
-
Simulation & Testing: Used as a virtual controller to test PLC code and HMI screens before deploying to physical hardware.
-
Material Handling: Systems that require tight integration between high-level sorting algorithms (PC-based) and low-level conveyor control (PLC-based).
-
Gateway Applications: Serving as a bridge between high-level enterprise IT networks and the factory floor OT networks.
