The Opto 22 SNAP I/O system interfaces with devices connected to SNAP
input and output I/O modules. A device connected to an input module is
read by the SNAP I/O Brain. The SNAP Brain processes the information
and sends it to the host PC running the Process 2000 software. In the
reverse direction, the Process 2000 PC sends an instruction to the SNAP
Brain and the Brain processes the request and sends it to the appropriate
output module to turn a device on or off, or to set it to a value.
Communications with a host computer is via an RS-485 serial link that
connects to the SNAP I/O Brain.
Disconnect all power from the SNAP I/O system before starting
these procedures.
Components of the SNAP I/O System
The components used in the Opto 22 SNAP I/O System consist of:
• SNAP Brain
• SNAP input/output modules
• SNAP rack
• Power supply
The SNAP Brain is the core of the I/O system. Using the SNAP I/O
modules, it monitors and controls all connected I/O points and provides
communication functions.
OPTO Brain B3000-B
The B3000-B is a mistic serial brain designed as a modern drop-in
replacement for the serial B3000 brain, which is obsolete as of October
2009.
The B3000-B has the same functionality as the B3000, except that it does
not support the Optomux protocol. Customers replacing the B3000 with
the B3000-B are required to update to the Process 2000 software AMETEK
part number 88175P Process 2000.
Like the older B3000, the B3000-B is a high-performance processor used to
remotely control a mix of SNAP analog and digital I/O modules on a B-
series rack. The brain connects to an Opto 22 controller or a host
computer over an RS-485 serial link.
