0920 DSL 001-DeviceNet Network Adapter

0920 DSL 001-DeviceNet Network Adapter
0920 DSL 001- DeviceNet Network Adapter
� The 0920 DSL 001 Network Adapter connects the DeviceNet Network to the 5 pin Open Connector.
� The 0920 DSL 001 Network Adapter acts as a slave in a master/slave environment.
� Its I/O data is exchanged with the master through a polled, bit-strobe, cyclic, or change-of-state connection.
� It that are extended to up to 32 Expansion units for the flexibility of node size.
�Each Network Adapter can process at a maximum of 512 digital input and output signals, or
32 analog input and output channels.
�The 0920 DSL 001 Network Adapter has indicators that provide a diagnostic readout (module status,
network status, expansion unit status, and field power status).
�ODVA conformance tested indicates there is a verified high level of interoperability with other
DeviceNet products.
� Supports auto baud rate detection.
� Sets node addresses using rotary switches.
