Availability: Obsolete
OBSOLETE SNAP Analog/Digital Brain, mistic/Optomux Protocol

Production Specification

**NOTE: The B3000 is obsolete and no longer available as of October 2009, due to the unavailability of essential parts.**

If you need a replacement for a B3000 used with the mistic protocol, see the B3000-B.

To replace a B3000 used with Optomux, see the B3000-B-OMUX.

NOTE: If you have an existing B3000 and need to purchase additional SNAP I/O modules to use with it, see Legacy and Current Product Comparison and Compatibility Charts for compatibility information.

This manual describes the communication protocol required to communicate with all Mistic brain board types. Every Mistic command is fully explained and illustrated by a programming example.

Tech Note: Using the B3000 in Custom Apps and 3rd-Party Drivers

This technical note describes how to configure module types used with B3000 brains when using a custom application or third-party driver that supports the mistic or Optomux Protocol but does not support configuring module types for the B3000. The information in this technical note does not apply to the B3000-B.

SNAP PAC System Migration Technical Note

This document describes migration options for customers integrating the SNAP PAC System with older Opto 22 systems. It explains the SNAP PAC System's similarities and differences with earlier systems, defines legacy products, and shows how to mix old and new hardware.

Customers moving to the SNAP PAC System may also want to consult form #1693, Legacy and Current Product Comparison and Compatibility Charts.

Technical Note: Using Offset and Gain

This technical note shows you how to set offset and gain for Opto 22 analog input modules.

Mistic I/O is a serial (RS422/485) protocol allowing up to 4,096 I/O points (per serial link) to be connected to a computer or Mistic controller used with Mistic-protocol brains and brain boards such as the B100, B200, and B3000. For use with Mistic controllers and I/O.

Mistic I/O is a serial (RS422/485) protocol allowing up to 4,096 I/O points (per serial link) to be connected to a computer or Mistic controller used with Mistic-protocol brains and brain boards such as the B100, B200, and B3000. For Microsoft Windows 95/Windows NT users.

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.


This file is used to configure analog I/O channels on the B3000 serial brain. Snapio.exe is typically used for applications with 3rd party software such as Wonderware or Intellution and a Mistic or Optomux protocol driver. After configuring the analog channels, the configuration is stored to flash in the B3000 serial brain, and your the third party software can read and write the I/O values.
