SNAP-PAC-EB Brains
The Opto22 SNAP-PAC brains provide intelligent management of analog, digital, and serial I/O modules in
distributed control applications. Localized functions include latching, counting, PID (up to 96 per brain) loop control,
watchdog timers, and event/reactions. The brains are installed on PAC racks providing 4, 8, 12, or 16 module
capacity (SNAP-PAC-RCK-xx).
There are two EB series brains which are identical except that the SNAP-PAC-EB1 brain features high speed digital
functions and analog ramping while the SNAP-PAC-EB2 brain does not.
Dual Ethernet Ports. EB brains feature dual Ethernet ports with a single IP address. This allows the brain to act as
an ethernet switch so that a series of brains can be daisy chained (yes, that's correct !) to simplify communications
wiring.
Communications. A variety of communications options provide great flexibility. Supported communications
protocols include TCP/IP, SNMP, SMTP, FTP, ModBus/TCP, OPC, IEEE 1394 based memory map, and others.
Wireless Ethernet is easily implemented.
Programming. EB brains can be controlled via PAC Project software applications or by custom end user Visual
Basic or C++ programs using the OptoMMP memory map. A software developer's kit is free and provides code
examples, DLL's, ActiveX components, etc.
Digital Features. Supported features include input latching, on/off status, watchdog timer, event-reaction, counters,
and quadrature counters.
Analog Features. Supported features include thermocouple linearization, min/max values, offset and gain, scaling,
time proportional output, filter weight, and watchdog timer.
Serial Features. Using special purpose serial modules, ASCII strings can be sent and received from serial devices
such as barcode readers, message boards, and CNC machines.
Event-Reaction. A powerful event-reaction capability gives the Brain the ability to respond to a variety of input
triggers without using any programming. Triggers (the event) include digital states, a specific high or low value of
an analog point, a specific serial string, a counter value, and many others. Reactions include turning a digital point
on or off, sending a serial string, transmitting an email message, and others. A simple example of an
event-reaction would be turning on a pump (reaction) in response to a high level switch (event).
