Chapter 1 General
The Ethernet module EN6** (called the EN6 module in this manual) and EB6** (called
the EB6 module in the manual) are devices for connecting controllers of the Integrated
Controller V Series to the monitoring and control network Ethernet (conforming to
IEEE802.3) for that series.
The 10BASE5 and 10BASE2 interfaces are available to the EN6 modules, and each of
these interfaces comes in the single bus type and dual bus type. Up to four EN6 modules
can be installed per base unit.
In a system of dual transmission line configuration, use a module (EN621 or EN641) for
line A in combination with a module (EB621 or EB641) for line B.
External views of the EN6 and EB6 modules, the Ethernet features and system
configuration examples are shown below.
• EN611:
Module for 10BASE5 single bus
• EN621/EB621: Modules for 10BASE5 dual bus
• EN631:
Module for 10BASE2 single bus
• EN641/EB641: Modules for 10BASE2 dual bus
• EN651:
Module for 100BASE-TX/10BASE-T single bus
• EN651A:
Module for 100BASE-TX/10BASE-T single bus
• EN661:
Module for 100BASE-TX/10BASE-T dual bus
