OPTO 22 E1 Manual

E1 and E2 Brain Boards
Features
Drop-in replacement for existing B1 and B2 brain boards
on an Optomux serial network
Dual network connectivity: RS-422/485 serial and
10/100 Mbps Ethernet
Optomux, Modbus/TCP, and OptoMMP protocol support
Can use Opto 22 ioProject software for control, HMI, and
OPC server
Description
E1 and E2 brain boards are Ethernet-ready I/O and communication
processors for digital and analog I/O systems. The E1 connects to a
rack of Opto 22 G1, G4, or Quad Pak
E2 connects to a rack of Opto 22 G1 analog I/O modules. Each brain
board communicates with a host computer and performs control
functions for each I/O point. Designed as drop-in replacements for
Opto 22's serial-based B1 and B2 brain boards, E1 and E2 brain
boards connect to standard 10/100 Mbps Ethernet networks while
including support for serial Optomux
Communication and Protocol Support
Ethernet support makes E1 and E2 brain boards ideal for upgrading
existing Optomux I/O systems to use Ethernet networking while
preserving existing I/O racks, modules, and field wiring. Using RS-
422/485 serial networks, E1 and E2 brain boards provide Optomux-
based capabilities identical to B1 and B2 brain boards.
When Ethernet networks are used, E1 and E2 I/O units also support
Modbus/TCP clients, custom Optomux applications migrated to
Ethernet, custom software applications written using Opto 22's
™
memory-mapped OptoMMP communication protocol, and
applications using Opto 22's ioProject
™
ioControl for flowchart-based programming, ioDisplay
™
and OptoOPCServer for data connectivity with OLE for Process
Control (OPC) 2.0-compliant clients.
Because the E1 and E2 can use these Ethernet-based protocols
simultaneously while still communicating with an existing
Optomux software application via a serial network, E1 and E2 brain
boards greatly expand your options for controlling and monitoring
your I/O system.
Programming and Configuration
There are several options for controlling, monitoring, and acquiring
data from E1 and E2 brain boards.

Optomux over serial or Ethernet networks
• Use your existing serial-based Optomux host application. Here,
one E1 or E2 brain board routes Optomux commands from a
serial connection to other brain boards connected to an Ether-
net network. This approach is illustrated in the system diagram
on page 6.
• Migrate your existing serial-based Optomux host application to
Ethernet. The Optomux for Ethernet software toolkit is shipped
with E1 and E2 brain boards and can also be downloaded free
of charge from the Opto 22 Web site.
Communication settings for connecting to an Optomux serial
network are made using on-board jumpers.
Ethernet-based communication options
• Use an Ethernet-based Opto 22 industrial controller that runs
an ioControl strategy (or control program) and communicates
with all Opto 22 devices on the Ethernet network. This
approach also makes it possible to use the ioProject software
applications ioDisplay for HMI and OptoOPCServer for OPC data
connectivity. See page 7 for an illustration of an I/O system
controlled and monitored by ioProject software.
