Product Overview
The Yokogawa ACM71 functions as a high-speed data gateway, bridging field control stations with Ethernet networks. It utilizes the IEEE802.3 standard to facilitate real-time data transmission between the communication module nest and external hubs. This module serves as a critical link for operators requiring stable 10 Mbps throughput in distributed control architectures.

Engineering Advantages
-
Seamless Integration: The ACM71 fits directly into the Yokogawa Communication Module Nest, allowing engineers to combine it with ACM21 or ACM22 modules for multi-protocol environments.
-
Real-Time Diagnostics: Three dedicated LED indicators (SND, RCV, RDY) provide immediate visual confirmation of network traffic and hardware health, accelerating troubleshooting during commissioning.
-
Standardized Connectivity: The RJ45 interface and point-to-point hub connection simplify wiring, reducing the need for proprietary cabling and lowering installation costs.
-
Low Thermal Footprint: The module draws minimal current (under 1.2 A), preventing heat buildup in densely packed control cabinets and extending the lifespan of adjacent components.
FAQs
Does the ACM71 require shielded cable for 100-meter runs?
The module design supports unshielded twisted-pair (UTP) cables for distances up to 100 meters per segment, providing reliable data integrity without the complexity of grounding shields.
Can the ACM71 operate alongside serial modules?
Yes, the system architecture supports the simultaneous use of ACM71 Ethernet modules with ACM21 or ACM22 serial modules within the same nest to handle diverse field device protocols.
What does a dark RDY LED indicate?
A dark RDY LED signals a hardware abnormality or power failure. Technicians should verify the 5.0V DC supply and ensure the module sits securely in the nest backplane.
Is this module hot-swappable?
Operators must follow Yokogawa safety protocols regarding the specific nest model; generally, users should power down the nest or confirm the control station's redundancy status before replacing modules to prevent data loss.
