Ethernet TCP/IP Automation Level Network
The Ethernet Automation Level Network (EALN) uses TCP/IP-based communication
over a customer’s Ethernet cabling and IP network to reduce overall system and
maintenance costs. Otherwise, system operation is identical to RS-485 ALN
installations.
An Insight workstation is optional with this ALN.
When an Insight workstation is used, multiple Insight workstations can be defined
on the MLN.
A maximum of 1000 Ethernet field panels can be defined for each Insight
workstation on the MLN.
Each Insight workstation can host up to 64 EALNs.
The Insight workstation counts as a node on every EALN to which it is connected.
Information can be sent and retrieved across the EALN from any Ethernet capable field
panel. The following figure shows a possible implementation of EALN over a corporate
IP network. In this example, the MBCs contain Power Open Processors with Ethernet
ALN.
