Isysnet 3

Selecting a Network
You can configure your system for information exchange between a range of devices and computing platforms and operating
systems.
Application Requirements Network Select
• Plant management (material handling)
• Configuration, data collection, and control on a single,
high-speed network EtherNet/IP PSSCENA
• Time-critical applications with no established schedule
• Data sent regularly
• Internet/Intranet connection
• High-speed transfer of time-critical data between
controllers and I/O devices
• Deterministic and repeatable data delivery
• Media redundancy ControlNet PSSCCNA
• Controller redundancy
• Intrinsic safety
• Redundant controller systems
• Connections of low-level devices directly to
plant-floor controllers, without interfacing them
• Data sent as needed PSSCDM12A
• More diagnostics for improved data collection and DeviceNet PSSCDM18PA
fault detection
• Less wiring and reduced start-up time than a traditional,
hard-wired system

• Connecting to an existing PROFIBUS DP 5m bus,
12 MB network PROFIBUS PSSCPBA

Selecting the DeviceNet Communication Interface
Isysnet offers two interfaces for connecting to DeviceNet. Refer to the following table.
For These Features Remember Select

• Behaves as a slave device on the Main • All Isysnet modules count as a single PSSCDM12A (M12-style network
Network and a master on the PointBus node on the Main Network connectors)
• Allows a group of I/O modules on the • The Main Network distance PSSCDM18PA (mini-style network
Subnet to act as a single node on the is acceptable connectors with pass-through)
Main Network
• Isysnet expansion power supplies are
• RSNetWorx™ for DeviceNet software permitted to add more Isysnet modules.
is needed for configuration of the
PSSCDM12A or PSSCDM18PA
on the Main Network and the PointBus
• Configuration on the PointBus consists
of a scan list that is very similar to
those used in all of the DeviceNet
master scanner modules
