Using Hmi; Hmi Connected Via An Ethernet/Ip Network - Allen-Bradley 1756-RM User Manual

Chapter 2 Design an Enhanced Redundancy System

Using HMI

46
Depending on the network used to connect the redundant system to HMIs, plan
for certain placement and configuration requirements. You can connect an HMI
to a primary chassis over either of these networks:
• EtherNet/IP
• ControlNet

HMI Connected via an EtherNet/IP Network

This table describes redundant system considerations specific to the HMI being
used on the EtherNet/IP network.
Type of HMI Used
PanelView Standard terminal
• PanelView Plus terminal
• VersaView® industrial computer running
a Windows CE operating system
FactoryTalk View Supervisory Edition
software with RSLinx Enterprise software
• FactoryTalk View Supervisory Edition
software with RSLinx Classic software,
version 2.52 or later
• RSView®32 software
• Any other HMI client software that uses
RSLinx Classic software, version 2.52 or
later
HMI connected to a redundant chassis pair exclusively over an EtherNet/IP
network can briefly drop the connection when a switchover occurs. The
connection is re-established, however, after the switchover is complete.

Considerations
Same as a nonredundant system.
• Use RSLinx Enterprise software, version 5.0 or later.
• Set aside connections for each PanelView Plus or VersaView CE
terminal as indicated in this table.
In this module Reserve
Controller 5 connections
1756-EN2T 5 connections
• Use RSLinx Enterprise communication software, version 5.0 or later.
• Keep the HMI and both redundant chassis on the same subnet.
• Configure the network to use IP swapping.
Limit the number of RSLinx servers that a controller uses to 1...3
servers, where the use of 1 server is ideal.
