Product Overview

The ANR10D-423 stands as a pivotal communication and power distribution hub within the Yokogawa CENTUM VP and CENTUM CS 3000 architectures. As an ER Bus Node Unit, its primary function is to bridge field-level analog and digital I/O signals with the centralized Field Control Unit (FCU). This module not only facilitates high-integrity data transmission across the ER bus protocol but also serves as the local power source for up to eight I/O modules housed within its chassis. By utilizing the ANR10D-423, industrial operators can effectively extend their system's reach to remote locations while maintaining the rigorous timing and synchronization required for complex process automation.

Critical Hardware Specifications

The ANR10D-423 is a robust, rack-mounted assembly engineered for high-availability performance in demanding environments.

System Integration and Industrial Usage

The ANR10D-423 is designed for versatile deployment across distributed plant networks. Its integration capabilities vary depending on the host controller and database configuration:

• Vnet/IP Modernization: When integrated with AFV10 controllers using LFS1500/LFS1550, it allows for expanded node counts (up to 14 units per FCU), supporting large-scale data acquisition across expansive chemical or power facilities.

• Compact Field Control: Compatible with AFF50 controllers for localized or smaller-scale process units, maintaining a maximum of 3 node units per controller branch.

• Remote Instrumentation: Ideal for offshore platforms or remote pumping stations where I/O signals must be consolidated and sent back to a central host over the ER bus.

• Redundant Operations: The "D" in the model name signifies a duplexed configuration, making it suitable for safety-critical loops where power and communication redundancy are mandatory for operational continuity.

FAQ

Q: What hardware is required to connect the ANR10D-423 to my Field Control Unit?

A: You must install an EB401 ER Bus Interface Master Module into your ESB Bus Node Unit or Field Control Unit. For single configurations, the EB401 must occupy an odd-numbered slot with the adjacent right-side slot left empty.

Q: Is the T-type connector included with this unit?

A: Yes, the T-type connector for the ER Bus (model YCB146) is supplied as a standard accessory with the ANR10 series units to facilitate bus daisy-chaining.

Q: Can I use this unit in a hazardous environment?

A: The ANR10D-423 complies with FM and CSA Non-Incendive standards for specific hazardous locations. For installations following the ATEX Directive, you must verify the presence of the /ATDOC option code.

Q: How many ER Bus Node Units can I connect to a single AFV10 controller?

A: If the controller is running the LFS1500 software with the LFS1550 expansion package, you can connect up to 14 ER Bus Node Units. Without the expansion package, the limit is typically 3 units.

Q: What is the significance of the /NDEL option code mentioned in the documentation?

A: The /NDEL option code is mandatory when connecting the ANR10 node unit to AFF50 or AFV10 controllers to ensure proper firmware and communication protocol compatibility.
