SNAP Ethernet Brains Features Description High-performance, flexible SNAP Ethernet brains are part of Opto 22's SNAP Ethernet systems, which let you connect to stateof-the-art Opto 22 industrial I/O hardware using a standard TCP/IP Ethernet connection. Combined with analog, digital, and special-purpose I/O modules on a standard SNAP mounting rack, the SNAP Ethernet brain forms an I/O unit that can be used alone or as part of a distributed control system based on an Opto 22 industrial controller, such as the SNAP PAC standalone or rack-mounted programmable automation controllers. A SNAP Ethernet system can be attached to existing Ethernet networks, making it easy to add monitoring and control where necessary. Or you can use standard Ethernet hardware to build an independent control network. You can also communicate with the system via a modem connection using Point-to-Point Protocol (PPP). A modem connection is ideal for remote locations or other places where an Ethernet network is not practical. The SNAP Ethernet brain family includes three products: * The SNAP-B3000-ENET brain is designed to remotely interface with a mix of analog, digital, and serial modules. It is Factory Mutual approved. * The SNAP-ENET-RTC brain handles analog, digital, and serial signals and includes a battery-backed real-time clock. * The SNAP-ENET-D64 brain is a digital-only processor. (Not recommended for new development. Use a SNAP Simple brain instead; see form #1452). * pulse measurement, time-proportional output (TPO), and pulse generation, including N pulses, continuous square waves, on-pulses, and off-pulses. Analog--Thermocouple linearization (32-bit floating point for linearized values), minimum/maximum values, offset and gain, scaling, output clamping, time-proportional output, filter weight, and watchdog timer. In addition, each brain provides 16 proportional integral derivative (PID) loops for local control. When used with a SNAP PAC controller and ioControl Professional, analog ramping is also available. SNAP-B3000-ENET and SNAP-ENET-RTC brains can also use specialpurpose SNAP modules on the same mounting rack: * Serial communication modules--Send and receive ASCII strings to and from attached serial devices, such as chart recorders and barcode readers. * Profibus module--Interface with PROFIBUS DP(R) networks, using a standard electrical interface. * High-density digital modules--Work with up to 32 digital inputs or 32 digital outputs on each module, for up to 512 digital points on a 16-module rack. See page 5 for a detailed comparison of SNAP Ethernet I/O, SNAP Simple I/O, and SNAP Ultimate I/O features.

DATA SHEET SNAP-B3000-ENET Form 1083-070806 Used with SNAP mounting racks and SNAP I/O(R) modules, SNAP Ethernet brain functions include the following: * Digital--Input latching, on/off status, watchdog timer, and event/reactions. SNAP-B3000-ENET and SNAP-ENET-RTC brains also include high-speed counters when used with standard digital input modules, and quadrature counters when used with quadrature input modules.

I/O Mounting Racks and Modules Communication Options The analog/digital/serial SNAP-B3000-ENET and SNAP-ENET-RTC brains are connected to a SNAP B-series I/O mounting rack, which can hold either 4, 8, 12, or 16 Opto 22 SNAP I/O modules. SNAP 4channel digital modules can be placed in any of the first eight positions; analog, serial, and higher density digital modules can be placed in any position on a B-series rack. Note that these brains cannot support analog modules with more than four points. SNAP Ethernet brains can be part of a larger control system with a SNAP PAC programmable automation controller, or you can communicate directly with them using Ethernet networking or RS232 serial connections. Any of the following methods--or all of them simultaneously-- can be used to interface with SNAP Ethernet I/O units: * ioControl Basic or ioControl Professional--for a complete control system, the control strategy runs on a SNAP PAC programmable automation controller. ioControl Basic is included on the CD that comes with the controller; ioControl Professional is purchased separately or as part of ioProjectTM Professional. * Modbus/TCP driver--for interfacing with any third-party software or hardware that uses the Modbus/TCP protocol. * OptoOPCServerTM--providing OLE for Process Control (OPC) 2.0 access for OPC clients. Purchase separately or as part of the ioProject Professional software suite. * SNMP messaging--for communicating with SNMP-based enterprise management software. * OptoMMPTM Communications Toolkit--for programming custom applications for the Ethernet brain to communicate using the OptoMMP memory-mapped protocol. The toolkit includes an ActiveX(R) component and a C++ class, and is on the CD that comes with the brain. * Opto 22 FactoryFloor(R) 3.1 or newer and an Opto 22 M4series controller with a 100 Mbps Ethernet expansion card. Available separately. (Not recommended for new development; use ioProject instead.) SNAP Ethernet brains must be connected to the appropriate rack to avoid damage to the brain. The digital-only SNAP-ENET-D64 brain is connected to a SNAPD64RS I/O mounting rack, which can hold up to 16 4-channel digital input and output modules. This brain can be used only with 4-channel digital modules. Other Features All brains offer data streaming. SNAP Ethernet brains provide both 10- and 100-Mbps Fast Ethernet compatibility, with automatic speed negotiation and a standard RJ45 twisted-pair connector. The brains also include a serial port for maintenance and for modem communication using point-to-point protocol (PPP).
