E1 and E2 Brain Boards
This diagram shows an E1- and E2-
based I/O system controlled by
Modbus/TCP software.
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.
Modbus/TCP software running on a
PC communicates with the E1s and
E2s over the Ethernet network to
control and monitor I/O points.
Also connected to the Ethernet
network is a Modbus/TCP hardware
device that is monitoring I/O point
information independent of the
primary control system.
