Opto 22 SNAP PAC Ethernet Brain SNAP-PAC-EB1

The SNAP-PAC-EB1 brain is an I/O and communications processor for your control system. Designed primarily to work in distributed systems controlled by a SNAP PAC S-series or R-series controller, the SNAP-PAC-EB1 can also be used as intelligent remote I/O with Allen-Bradley Logix systems. The SNAP-PAC-EB1 provides local intelligence that frees the controller for supervisory tasks. As an I/O processor, the SNAP PAC brain independently handles functions such as latching, counting, thermocouple linearization, watchdog timers, and PID loop control. These functions continue to work on the brain even if communication with the controller is lost. The SNAP-PAC-EB1 brain supports all the SNAP I/O analog, digital, and serial input and output modules available on the Opto 22 website. These modules can all be mixed on the same mounting rack and placed in any position on the rack. The brain and modules mount on a SNAP PAC rack, which holds up to 4, 8, 12, or 16 modules. In addition to I/O processing, the SNAP PAC brain communicates over a standard 10/100 Mbps Ethernet network. The brain is equipped with two switched Ethernet network interfaces. Because these interfaces share a single IP address and act just like an Ethernet switch, SNAP PAC brains can be installed in a multi-drop (daisy-chain) configuration, extending the control network without the added expense of additional Ethernet network hardware. SNAP PAC brains can also be installed in a star configuration using standard, off-the-shelf Ethernet network components. The SNAP-PAC-EB1 brain supports communication using multiple protocols running simultaneously over Ethernet. Most customers use the PAC Project software suite for control, monitoring, and data acquisition. At the same time, you can communicate using other methods, including EtherNet/IP, Modbus/TCP, SNMP, SMTP, FTP, and OptoMMP. Communication with OPC 2.0-compliant clients is available through OptoOPCServer. The SNAP-PAC-EB1 brain offers high-speed digital functions, including high-speed counting (up to 20 KHz, depending on the module), quadrature counting, pulse generation and measurement, and TPO (time-proportional output). If you do not need high-speed digital functions, choose the SNAP-PAC-EB2 brain instead.
