ANB10D-F2

The Yokogawa ANB10D-F2 is an ESB Bus Node Unit designed to connect field input/output (I/O) modules with a Field Control Unit (FCU) through Yokogawa's ESB communication bus. It provides the communication interface between field signals and the control system while distributing power to installed I/O modules. The ANB10D platform supports a dual-redundant ESB bus configuration for distributed I/O architecture.

Functional Description

The ANB10D serves as a local I/O node in Yokogawa's Field Network I/O (FIO) architecture. It transfers analog and contact I/O signals between field-side modules and the FCU through the ESB bus.

The node unit also accommodates power supply modules, ESB bus interface slave modules, and I/O modules. This arrangement allows field signal interfaces to be organized in a separate node while maintaining communication with the central control unit.

Hardware Configuration

The ANB10D is designed for a dual-redundant ESB bus arrangement. Its hardware configuration supports redundant power supply and bus interface modules, allowing the corresponding hardware paths to be configured in pairs.

Key configuration characteristics include:

• Support for up to 8 installed I/O modules.
• Two power supply modules in a dual-redundant power configuration.
• Two SB401 ESB Bus Interface Slave Modules in a dual-redundant configuration.
• 19-inch rack mounting.
• Communication with the FCU through the ESB bus.

The actual installed I/O modules depend on the selected system configuration and applicable module specifications.

FCU Connection and System Requirements

Connection to a compatible Field Control Unit requires an ESB Bus Coupler Module. Yokogawa specifies EC401 or EC402 for the applicable FCU configurations.

For a dual-redundant FCU configuration, the coupler modules are installed in slots 7 and 8. For a single configuration, the coupler module is installed in slot 7, with slot 8 left empty.

The number of connectable node units depends on the FCU model and its software license. The published general specifications specify a maximum of 13 ANB10-series and ANB11-series nodes for applicable AFV30 and AFV40 configurations, subject to cabinet installation limitations.

Frequently Asked Questions

Q: What is the main function of the Yokogawa ANB10D-F2?

A: It connects field I/O modules to a Field Control Unit through the ESB bus. It also provides power distribution to the installed I/O modules.

Q: How many I/O modules can the ANB10D accommodate?

A: The published ANB10D general specifications support up to 8 I/O modules. Actual module selection and installation must follow the applicable FIO system configuration requirements.

Q: What is required to connect the ANB10D to an FCU?

A: An EC401 or EC402 ESB Bus Coupler Module is required for the applicable FCU configurations. The coupler installation position depends on whether the FCU uses a single or dual-redundant configuration.
