Description The B3000 is a high-performance brain used to remotely control a mix of both analog and digital I/O modules using Opto 22’s Snap® “B Series”I/O mounting racks. The B3000 can be used with either an Opto 22 controller or a host computer. On-board intelligence enables many distributed control functions. Since SNAP analog and digital modules have the same footprint, the B3000 brain can be combined with Snap “B Series” racks to provide the world’s most powerful and sophisticated I/O handling systems. The B3000 communicates with a host processor serially over RS485 twisted pair wiring and supports both the advanced Mistic® protocol and the industry-standard Optomux ® protocol. Both protocols can support high-speed communication (115 Kbaud). Utilizing the Mistic protocol, advanced I/O processing — including PID calculations (100 millisecond update), pulse width duration measurements (100 microsecond resolution), and high-speed counting (20,000 Hz) — can all be accomplished on separate channels of the same I/O mounting rack. See page 3 for a complete list of mistic functions.

The Optomux protocol is also capable of providing input averaging and output waveform functions on analog channels. See page 4 for a complete list of Optomux functions. The B3000 is compatible with the classic B1 and B2 brains, with a few exceptions. The B3000 adds the ability to communicate with either a 2-wire or 4-wire configuration, at speeds of 115 Kbaud. Classic brains were restricted to 4-wire communications at up to 38.4 Kbaud. The B3000 now supports only the standard 2-pass method of communication with the Optomux protocol. By using the B3000 with the Mistic protocol and a Mistic controller, SNAP I/O customers can take advantage of FactoryFloor®, Opto 22’s impressive new suite of Windows® 32-bit software that delivers total control to industrial automation customers. FactoryFloor consists of four integrated components: OptoControl is the cornerstone of Opto 22’s FactoryFloor software and is the programming environment that leverages all the power of Opto 22’s distributed hardware platform. OptoControl utilizes the distributed control capability of the B3000 brain and takes advantage of the graphical Windows 95 or NT interface to make it easy to configure, design, and troubleshoot your control system. Opto 22’s OptoDriver Toolkit™ may be used for direct communications from a host PC to the B3000. The toolkit includes new 32-bit Windows drivers, Windows 16-bit drivers, and Opto 22’s classic DOS drivers. The kit also provides the files, documentation, and real-world examples needed to write Microsoft ® Windows and DOS software applications. Programmers can access the Opto 22 I/O hardware using highlevel languages such as Microsoft Visual C++™ or Microsoft Visual Basic®. • OptoControl ™, a graphical, flowchart-based development environment for control solutions • OptoDisplay™, a graphical, multimedia operator interface package • OptoServer™, a robust data server that connects the controller network with the PC-based FactoryFloor network. • Plus OptoConnect™, a drag-and-drop database utility that makes building SQL Server and Access databases a snap.

Although you may elect to use other cables, keep in mind that low capacitance (less than 15 pF/ft.) is important for high-speed digital communication links. The cables listed below are all 24-gauge, 7x32 stranded, with 100-ohm nominal impedance and a capacitance of 12.5 pF/ft. Select from the following two-, three-, and four-pair cables, depending on your application needs. All will yield satisfactory results. It is recommended that you choose a cable with one more pair than your application requires. Use one of the extra wires, rather than the shield, for the common.

Digital modules (either input or output) contain four channels of I/ O. Analog input modules contain two channels and analog output modules currently contain two channels. Both analog and digital modules can be on the same rack. A B3000 is capable of addressing a maximum of 32 channels of digital I/O and 32 channels of analog I/O. However, the I/O mounting racks will not accommodate 32 channels of both digital and analog. The actual number of channels available depend on the combination of modules chosen. For example, the SNAP-B16M rack can mount 16 modules. Up to eight of these modules can be digital, providing 32 channels of digital I/O. The remaining eight module positions can be analog, providing up to 16 channels of analog I/O. If all 16 modules are analog, up to 32 channels of analog I/O are available. I/O on the B3000 is divided into four addresses of I/O (two digital I/O and two analog I/O). The digital addresses are base+0 and base+1. The analog addresses are base+2 and base+3. Therefore, if a SNAP brain is configured at address 12, the digital addresses would be 12 and 13 and the analog would be 14 and 15. First Four Module Positions (0-3): Each position can hold either a digital or an analog module. They can be all analog, all digital, or any mix of both. These four positions constitute the 16 digital channels of digital address base + 0, and the first eight analog channels of analog address base + 2. Second Four Module Positions (4-7): Each position can hold either a digital or an analog module. They can be all analog, all digital or any mix of both. These four positions constitute the 16 digital channels of digital address base + 1, or the second eight analog channels of analog address base + 2. Third Four Module Positions (8-11): These positions can hold analog modules only. These four positions constitute the first eight analog channels of analog address base + 3. Fourth Four Module Positions (12-15): These positions can hold analog modules only. These four positions constitute the second eight analog channels of analog address base + 3. The layout is illustrated in Figure 1-1 on the previous page.

This fact will be indicated in OptoControl by text in the Configure I/O Points dialog, which will display information in the Name field for analog channels 0 and 1 stating that those channels are used by a SNAP digital module, and will specify the name of that I/O unit address. Digital When configuring the unit, select B3000 Snap Digital as the Type in the Add I/O Unit dialog. The digital addresses are base+0 and base+1. If the SNAP brain is configured at address 12 (base), the digital addresses would be 12 and 13 . When a point is configured, OptoControl automatically creates and configures the other three points in the module. For example, if a digital SNAP point is added at channel 5, then identical points are created at channels 4, 6, and 7. Unique names are created for these new points, based on the name entered for the original point. You can then modify the name, as well as the description, features, default, and watchdog for each channel independently. If the module type of one digital point is changed, then the module type of all other points in that module are automatically changed. Analog When configuring the unit, select B3000 SNAP Analog as the Type in the Add I/O Unit dialog. The analog addresses are base+2 and base+3. If the SNAP brain is configured at address 12 (base), the analog addresses would be 14 and 15. Inputs: When an input is configured, OptoControl automatically creates and configures the other input channel on that module. The name of the other channel can then be modified, as well as the description, default, and watchdog fields. The module type and scaling cannot be modified. Outputs: Single-channel analog output modules use two analog channels, but they contain only one channel of output. Only the even-numbered channel is usable, e.g., 0, 2, 4, etc. The odd-numbered channel is not valid. Opto 22 also produces 2-channel analog output modules. Other Notes Event/reactions and PID Loops can only operate on points in the same address group. They behave just like standard I/O in this sense, and cannot cross address boundaries. For example, a PID loop cannot use an input on Address Base + 2, to control an output on Base + 3. Up to 127 event/reactions can be configured per SNAP address.
