network, and drive. The status indicators for the interface can be viewed on the
front cover of the drive when the drive is powered.
Stop Action When communication is disrupted (for example, a cable is disconnected), the
interface and drive can respond with a stop action. A stop action results in the
drive receiving zero as values for logic command, reference, and datalink data
and an additional command that causes the drive to stop.
and design elements into a common environment. The first element in the
Studio 5000 environment is the Logix Designer application. The Logix
Designer application is the rebranding of RSLogix 5000 software. It continues
to be the product to program Logix 5000 controllers for discrete, process,
batch, motion, safety, and drive-based solutions.
The Studio 5000 environment is the foundation for the future of Rockwell
Automation engineering design tools and capabilities. It is the one place for
design engineers to develop all elements of their control system.
multiple physical networks. A bit mask identifies the part of the address that
specifies the network and the part of the address that specifies the unique node
on the network. A '1' in the subnet mask indicates the bit is used to specify the
network. A '0' in the subnet mask indicates that the bit is used to specify the
node.
For example, a subnet mask on a network can appear as follows: 11111111
11111111 11111111 11000000 (255.255.255.192). This mask indicates that
26-bits are used to identify the network and 6-bits are used to identify devices
on each network. Instead of a physical Class C network with 254 devices, this
subnet mask divides it into four networks with up to 62 devices each.
Switches Network devices that provide virtual connections that help to control
collisions and reduce traffic on the network. They are able to reduce network
congestion by transmitting packets to an individual port only if they are
destined for the connected device. In a control application, in which real-time
data access is critical, network switches can be required in place of hubs.
EtherNet/IP uses this protocol to transfer Explicit Messaging packets over IP.
