1785-SO036C-EN-P - April 2002
PLC-5 DeviceNet Scanner Module The 1771-SDN/C PLC-5 DeviceNet scanner module acts as an
interface between DeviceNet devices and the PLC-5
programmable controller. The scanner module communicates
with DeviceNet devices using the latest DeviceNet Master
Library (DML) to:
• read inputs from a device
• write outputs to a device
• download configuration data
• monitor a device’s operation status
Communicating in the form of block transfers and discrete I/O,
the scanner module exchanges device I/O data, status
information and configuration data. The scanner has two
channels that let you connect to two DeviceNet networks.
The 1771-SDN/C scanner module is a direct replacement for
the series B version - but has new features and benefits. The
series C module has a series B-compatible switch setting to
allow for direct replacement of a series B module without
requiring any changes to the existing system.
Features
• improved performance over
Series B
• Auto Device Replacement (ADR)
• shared inputs between scanners
wihtout separate connections
• change of state, cyclic I/O,
pass-through and slave mode
capability
• electronic keying
• I/O data server for explicit
peer-to-peer messaging
• network access to scanner
diagnostice tables such as idle,
node status, fault
• improved enable/disable of slaves
in scan list
• ODVA compliant
