BrainBox IO Connector

Overview

The Brainboxes connector provides tag-based read/write access to a Brainboxes Ethernet I/O device (digital inputs/outputs, analog inputs), using the Brainboxes.IO SDK. It is event-driven, not polled - the connector subscribes to the device's own hardware change-notification events (IOLineRisingEdge, IOLineFallingEdge, analog line-change events) and updates tags as those events fire, rather than reading on a timer.

Automatically reconnects on disconnection via a background retry loop.

Note: this connector does not auto-register discovered I/O points as tags. On connect, it queries the device for its actual inputs/outputs, but these are only used to log/set local values - they are not added to the connector's tag dictionary. Tags must be configured externally (matching name convention below) for the connector to actually read/write them.

Parameters

Supported Tag Types:

The connector maps onto the standard Industreweb tag types below. For Integer Tag, Decimal Tag, Time Span Tag, and Data Tag - where more than one Allen Bradley elementary type could apply - the specific AB type is selected using a DataType entry in the tag's Parameters. Bool Tag and String Tag don't need this, since each maps to exactly one AB type.

Tag Name must follow the convention DI<n> / DO<n> / AI<n> (matching the device's own I/O numbering) for the connector's event handlers to find and update the correct tag.

Connector Methods

Addressing

The Address field (DIADDRESS<n>/DOADDRESS<n>/AIADDRESS<n>) is used to determine the physical I/O index when writing to a digital output - the numeric suffix is parsed from Address, not Name.
