Product Introduction

The Schneider Electric 140NOL91100 is a high-reliability logic controller module designed for use within the Modicon Quantum series of programmable automation controllers. Specifically engineered to execute logic tasks at the I/O or communication level, this module operates as a local logic decision-maker rather than a full CPU. It is commonly referred to as a logic coprocessor or application-specific logic module that enhances the processing capacity of Quantum systems in distributed or modular configurations.

Its role is to offload processing tasks from the main CPU, manage time-critical functions locally, and increase the overall responsiveness of the automation system. Ideal for complex industrial environments, the 140NOL91100 is seamlessly integrated with other Quantum modules via the local backplane bus, providing deterministic behavior and support for custom logic execution.

This makes it a valuable asset for facilities requiring modularity, speed, and distributed control—such as manufacturing, petrochemical, power generation, and infrastructure systems.

Frequently Asked Questions (FAQ)

1. What is the primary function of the 140NOL91100 module?
It serves as a logic processor within a Quantum rack, handling specific control tasks independently of the main CPU.

2. Can this module operate without a Quantum CPU?
No, it requires a Quantum CPU for overall program management and communication coordination.

3. What software is used to program this module?
You can program it using Unity Pro or EcoStruxure Control Expert.

4. Does it store programs locally?
Yes, it includes non-volatile memory to retain logic code even during power loss.

5. Can it be used for safety-critical tasks?
It is not SIL-rated for safety applications but can perform fast control logic when used with certified safety systems.

6. How is the module powered?
It draws approximately 400 mA at 5 VDC directly from the Quantum backplane.

7. How do I know if the module is functioning correctly?
Front-facing LEDs indicate RUN, ERROR, and I/O statuses for easy troubleshooting.

8. What communication methods are supported?
Communication is handled internally via the Quantum backplane bus. It does not have external network ports.

9. Is the module hot-swappable?
While some operations may allow hot-swapping, it is recommended to power down the system during replacement for safety.

10. What type of logic programming is supported?
It supports ladder logic, structured text, and function block programming based on IEC 61131-3 standards.
