The EI802F (Part Number: 3BDH000016R1) is a high-performance communication module for the ABB Freelance AC 800F controller family. It provides the controller with a standard Ethernet interface, enabling seamless connection to the system bus (DigiNet S), plant networks, or third-party devices via Modbus TCP. This module is essential for integrating the AC 800F into a distributed control system (DCS) or connecting it to human-machine interfaces (HMIs) and engineering workstations.
Product Datasheet & Parameters
Product Technical Description
The EI802F acts as the networking gateway for the AC 800F field controller. It is designed to handle industrial communication traffic with high reliability and deterministic timing.
Key Technical Attributes:
-
Autonegotiation: Automatically detects the network speed (10 or 100 Mbps) and duplex mode, simplifying the commissioning process.
-
Redundancy Support: In high-availability configurations, two EI802F modules can be used in a single AC 800F controller to provide redundant system bus communication.
-
Galvanic Isolation: The Ethernet port is galvanically isolated to prevent ground loops and protect the controller’s internal electronics from network transients.
-
Integrated Diagnostics: Features front-panel LED indicators (Link, Activity, Speed, and Status) for immediate visual monitoring of the network health.

Common Questions & Answers (Q&A)
Q: What is the difference between the EI803F and the EI802F? A: The EI802F is the standard 10/100 Mbps copper (RJ45) interface, whereas the EI803F is the fiber optic version (100 Base-FX) designed for long-distance communication and high EMI environments.
Q: Does the EI802F require its own IP address? A: Yes. The IP address for the EI802F is typically assigned through the Freelance Engineering software during the hardware configuration phase.
Q: Can this module be used for Modbus TCP communication? A: Yes, the EI802F supports Modbus TCP, allowing the AC 800F to act as either a client or a server when communicating with third-party PLCs, drives, or smart sensors.
Q: Is it hot-swappable? A: No. You should always power down the AC 800F controller before removing or inserting the EI802F module to avoid potential bus errors or electrical damage to the communication pins.
