The AEG AS-B814-108 is a Modicon 984 Series network interface controller designed for MAP 3.0 broadband communication within industrial automation systems. In particular, it provides a communication interface between compatible control equipment and the industrial network, helping controllers exchange process and system information efficiently. In addition, its design makes it suitable for maintaining established Modicon-based automation architectures.

Product Overview

This module belongs to the Modicon 984 family and is identified in parts databases as a broadband network interface controller. Therefore, its primary role is related to industrial network communication rather than direct field signal conditioning.

Moreover, the unit is associated with MAP 3.0 networking, a communication architecture used in industrial automation environments. As a result, it can serve as an important interface within legacy control systems that depend on compatible network infrastructure.

Key Specifications

The main available product information can be summarized as follows:

• Product family: Modicon 984 Series
• Product type: Network interface controller
• Network technology: MAP 3.0
• Communication class: Broadband industrial networking
• Primary function: Network communication and controller interfacing
• System role: Interface module for compatible automation equipment
• Application focus: Industrial control and legacy automation networks

Because detailed electrical specifications are not consistently published in the available sources, installation-specific values should be verified against the applicable equipment documentation before commissioning. This approach is particularly important when replacing an existing communication module.

Design and Communication Role

The module is intended to function as a communication component within a compatible control architecture. First, it provides the network interface required by the associated automation equipment. Furthermore, its broadband communication design allows it to participate in a structured industrial network environment.

At the system level, the module can connect control resources with the communication infrastructure. Meanwhile, the PLC and associated devices can continue performing their respective control functions. Consequently, the interface helps separate network communication tasks from the primary control logic.

Typical Industrial Uses

The unit is mainly relevant to industrial facilities that continue to operate Modicon 984-based systems. For example, it may be considered for manufacturing equipment, process automation, production machinery, and distributed control installations using compatible MAP networking.

In addition, it can be useful when maintaining older automation systems where replacing the entire control architecture would require extensive engineering work. Therefore, retaining a compatible network interface can simplify maintenance and help preserve an established system configuration.

Installation and Maintenance

Before installation, technicians should confirm compatibility with the PLC hardware, network architecture, and associated communication equipment. Next, the network connection and module position should be checked against the system documentation.

Furthermore, communication wiring should be inspected for physical damage, loose connections, or signs of deterioration. During maintenance, technicians should also review network status and controller diagnostics. If communication problems occur, checking the network connection first can help narrow down the possible cause.

Finally, replacement work should include a functional communication test after installation. This step helps verify that the controller can communicate correctly with the surrounding automation network.

Replacement Considerations

When sourcing a replacement, the exact part number and system generation should be verified carefully. In particular, compatibility should not be determined only by the physical appearance of the module.

The network architecture, controller platform, communication method, and existing configuration should also be considered. Moreover, because this equipment is associated with legacy Modicon systems, documentation and hardware condition should be reviewed before integration.

As a result, careful identification and pre-installation verification can reduce commissioning risks and support the continued operation of established industrial automation equipment.
