SNAP PAC Brain, analog/digital/serialSNAP-PAC-EB2The SNAP-PAC-EB2 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-EB2 can also be used as intelligent remote I/O with Allen-Bradley Logix systems. The SNAP-PAC-EB2 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, thermocouple linearization, watchdog timers, and PID loop control. These functions continue to work on the brain even if communication with the SNAP PAC controller is lost.

The SNAP-PAC-EB2 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 aSNAP 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 network. The brain is equipped with two switched network interfaces. Because these interfaces share a single IP address and act just like an switch, SNAP PAC brains can be installed in a multi-drop (daisy-chain) configuration, extending the control network without the added expense of additional network hardware. SNAP PAC brains can also be installed in a star configuration using standard, off-the-shelf network components.

The SNAP-PAC-EB2 brain supports communication using multiple protocols running simultaneously over . 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 /IP, Modbus/TCP, SNMP, SMTP, FTP, and OptoMMP. Communication with OPC pliant clients is available through OptoOPCServer.

The SNAP-PAC-EB2 brain provides basic digital functions but does not offer high-speed digital functions; if you need high-speed counting (up to 20 KHz depending on the module), quadrature counting, pulse measurement, and frequency and period measurement, choose theSNAP-PAC-EB1brain instead.
