Ethernet Expansion I/O
With Do-more Designer Software version V1.1 and newer, the H2-DM1E CPU’s built-in
Ethernet port can be configured as an Ethernet Expansion I/O master. Much like the ERM
module discussed in Chapter 7, the Ethernet Expansion I/O feature allows expansion beyond
the local chassis to slave I/O using the onboard high-speed Ethernet link.
The onboard Ethernet port can support up to 16 slave devices. The slave I/O modules
supported are:
• H2-EBC100
• T1H-EBC100 (Terminator I/O)
• GS-EDRV100 (GS Drives)
The Ethernet Expansion I/O network uses Category 5 UTP cables for cable runs up to 100
meters (328ft) with extended distances achieved through Ethernet switches.
WARNING: It is highly recommended that a dedicated network be used with the Ethernet Expansion I/O
feature. Ethernet Expansion I/O networks and ECOM/office networks should be isolated from one
another to prevent network delays. While Ethernet networks can handle a large number of data
transactions, and normally handle them very quickly, heavy Ethernet traffic can adversely affect the
reliability of the slave I/O and the speed of the I/O network.
