Isysnet 3
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
• RSNetWorx™ for DeviceNet software
• Isysnet expansion power supplies are
is needed for configuration of the
permitted to add more Isysnet modules.
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
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
