Getting Started Chapter 1
• Parameter-configured 32-bit datalinks in the I/O to meet application
requirements: 16 datalinks to write data from the network to the drive,
and 16 datalinks to read data to the network from the drive.
•Explicit Messaging support.
• User-defined fault actions to determine how the built-in
EtherNet/IP interface and its host PowerFlex 755T drive respond to the
following:
– I/O messaging communication disruptions (Comm Flt Action)
– Controllers in Program mode (Idle Flt Action)
– Explicit Messaging disruptions for drive control via PCCC or the
CIP based network Assembly Object (Msg Flt Action)
• Automatic Device Configuration (ADC), an RSLogix 5000 software,
and Studio 5000 environment feature, which support the automatic
downloads of configuration data.
Dual Ethernet Ports
Dual Ethernet ports provide connection for star, linear, or Device Level Ring
(DLR) network topologies.
Examples of different EtherNet/IP network topologies are shown in Figure 1
,
Figure 2
, and Figure 3. For information about linear and Device Level Ring
(DLR) topologies, see EtherNet/IP built-in Switch Technology, publication
ENET-AP005
.
Figure 1 - Connecting the Ethernet Cable in a Star Topology Network
IMPORTANT The adapter has EtherNet/IP built-in switch technology, and ENET1 and
ENET2 network ports to connect to a linear or Device Level Ring (DLR)
network in a subnet.
You cannot use the ENET1 and ENET 2 network ports as two network
interfaces that are connected to two different Internet Protocol (IP) subnets.
