Overview
The Yokogawa ANB10D‑445/CU2N/NDEL is a high-reliability Node Interface Module (NIM) designed to connect remote Field I/O (FIO) nodes to Vnet/IP or ESB bus networks. Widely used in CENTUM VP and ProSafe‑RS systems, this module provides deterministic communication, precise I/O scanning, and system-level diagnostics, making it essential for redundant and mission-critical industrial control applications.

FAQ
Q: Can this module support redundant controller configurations?
A: Yes, it supports dual-redundant communication and can operate with redundant controllers.
Q: Is Vnet/IP communication mandatory?
A: No, Vnet/IP is option-dependent. Without the option, communication occurs via ESB bus only.
Q: How many I/O modules can a node support?
A: Typically up to 16 modules, depending on the baseplate and module configuration.
