E1 and E2 Brain Boards
This diagram shows how an existing
Optomux-based I/O system for an
RS-422/485 serial network can be
migrated to an Ethernet network. In
this system, each original B1 or B2
brain board has been replaced with
an E1 or E2, and all brain boards are
connected to an Ethernet network.
One E1 or E2 brain board is
connected via an RS-422/485 serial
connection to the host PC running
the Optomux application. For each
Optomux command sent from the
PC, this brain board determines
which I/O unit the command must
be sent to and then routes the
command to that unit over the
Ethernet network. I/O point data is
routed from the E1 and E2 brain
boards to the PC in a similar
manner.
Because an Ethernet network is
used, the existing Optomux
application can now monitor and
control E1 and E2 I/O units located
far beyond the reach of the original
RS-422/485 serial network—for
example, in a different building, or
even on another continent.
For more information on using E1
and E2 brain boards in an existing
Optomux I/O system, see the E1 and
E2 Architecture and Migration
Overview (Opto 22 form 1567) and
the E1 and E2 User’s Guide (Opto 22
form 1563).
