Brain

The SNAP-PAC-EB1 brain is an I/O and communications processor for your control system. The SNAP-PAC-EB1 provides local intelligence that frees the controller (PAC or PLC) 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.
NOTE: In order to use Opto 22 serial modules with an EB2 brain, the I/O should be controlled by a SNAP PAC controller running a PAC Control strategy.
In addition to I/O processing, the SNAP PAC brain communicates over a standard 10/100 Mbps Ethernet network.
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.
If you do not need high-speed digital functions, choose the SNAP-PAC-EB2 brain instead.
If you need a Factory Mutual-approved version of this brain, see the SNAP-PAC-EB1-FM.

If you are not using PAC Project software and a SNAP PAC controller with this brain and instead need to communicate directly with it, see the SNAP PAC .NET OptoMMP SDK.
Build your system in the SNAP I/O Configurator.

Supports all the SNAP I/O analog, digital, and serial input and output modules available on the Opto 22 website.

Can be installed in a multi-drop (daisy-chain) configuration, extending the control network without the added expense of additional Ethernet network hardware.

Supports communication using multiple protocols running simultaneously over Ethernet.

At the same time, you can communicate using other methods, including EtherNet/IP, Modbus/TCP, SNMP, SMTP, FTP, and OptoMMP.

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).
