B2

Production Specification

*** End of Life *** Currently limited to stock on hand.

Please note: Because we can no longer obtain essential parts, we cannot continue to manufacture the B2.

Drop-in replacement: The E2 brain board is a drop-in replacement for the B2 and adds Ethernet capability as well as support for multiple protocols, including Optomux, Modbus/TCP, and OptoMMP. For more information on migration, see form 1567, the E1 and E2 Architecture and Migration Overview.

------------

The B2 brain board is an intelligent processor that operates as a slave device to a host computer via an RS-422/485 serial link. The B2 mounts on Opto 22 I/O racks with header connectors to control Standard (G1) analog I/O modules. The B2 uses the Optomux protocol.

Use this software developer toolkit to create custom programs for the B2 brain board:  Optomux Protocol drivers and utilities.

Compatible I/O and mounting racks are G1 analog I/O modules on PB4AH, PB8AH, and PB16AH racks.

E1 and E2 Architecture and Migration Overview

The E1 and E2 brain boards are Ethernet-ready I/O and communication processors for digital and analog I/O systems. Designed as drop-in replacements for Opto 22's serial-based B1 and B2 brain boards, the E1 and E2 support both serial and Ethernet networking and multiple simultaneous protocols, including Optomux, OptoMMP, and Modbus/TCP.

This overview describes the system capabilities of the E1 and E2 and illustrates methods for migrating existing Optomux systems to use Ethernet networking, while preserving existing I/O racks, modules, and field wiring.

Optomux 16-Channel Digital and Analog Brain Boards Data Sheet

The B1 digital and B2 analog Optomux brain boards are intelligent digital processors that operate as slave devices to a host computer. Each brain board contains a microprocessor that provides the necessary intelligence to communicate with a host computer and also perform control functions at each channel of I/O.

B1 and B2 User's Guide

Digital B1 and analog B2 brain boards use the Optomux protocol. For new installations, E1 and E2 brain boards are preferred. This guide includes B1- and B2-specific information that used to be in form #203, which is now obsolete. For Optomux information, see form #1572, the Optomux Protocol Guide.

Optomux Protocol Guide

The Optomux Protocol Guide provides complete command documentation and examples for programmers using either the Opto 22 Optomux Protocol Driver or the Optomux protocol itself. This guide replaces the previous forms #203 (Optomux Protocol User's Guide) and #92 (Optoware User's Guide).

CAD Drawing: B2 Analog Brain Board

This CAD file includes drawings for the analog Optomux B2 brain board, a legacy product.

Optomux Protocol drivers and utilities

This file installs drivers for E1, E2, B1, B2, and serial B3000 and B3000-B brains. It is based on the "iolib_optomux.dll" library. This toolkit is recommended for all new Optomux-based applications because it supports Optomux communications over both Ethernet and serial networks.

The toolkit can emulate the interface that the earlier library "OptoMWD.dll" provided; however, using this interface is not required. This legacy interface capability is included to help an existing OptoMWD.dll user make a smoother migration to this newer toolkit. The legacy utilities OptoScan and OmuxUser are also included.

This toolkit is compatible with Windows XP and Windows 2000 operating systems. It is not compatible with .NET programming languages.
