HMI

Depending on the network that is used to connect to HMI, plan for certain placement and configuration requirements. You can connect an HMI to a primary chassis over the
EtherNet/IP™
 network.
IMPORTANT:
To help prevent anomalous behavior, do not target active communication at the secondary chassis.
To communicate with HMI, the following methods are available:
  • IP address swapping—Supported by all HMI products. For more information, see IP Address Swapping.
  • Redundant controller shortcut paths—Supported by only
    FactoryTalk® View
     Site Edition with
    FactoryTalk® Linx
     software. For more information, see the High Availability Systems Reference Manual, publication HIGHAV-RM002.
The following table describes high availability system considerations for HMI on the
EtherNet/IP™
 network.

  • Use
    FactoryTalk® Linx
     software, version 5.0 or later.
  • Keep the HMI and both redundant chassis on the same subnet.
  • To help reduce data server recovery switchover time, consider using redundant controller shortcut paths.
