Section 1-3
DeviceNet Configurator The DeviceNet Configurator is a Windows-based application that supports
construction of DeviceNet networks. The Configurator is used not only for set-
ting parameters and monitoring OMRON Master and Slave devices, but also
for setting parameters for slaves from other manufacturers, simply by installing
the EDS files.
The Configurator provides extensive support for managing networks, from
design through to maintenance.
NetXServer for DeviceNet The NetXServer is middleware that operates in a Windows environment. The
NetXServer collects I/O data from a DeviceNet network and provides it to
monitoring and other applications. It operates as a DDE server.
NetXServer enables I/O data monitoring without affecting Master or Slave
communications.
The following two types of NetXServer are available:
DDE Edition: For monitoring I/O data using a DDE client (e.g., Microsoft
Excel)
SDK Edition: Library for developing monitoring applications using NetXServer
functions
DeviceNet Analyzer The DeviceNet Analyzer is a Windows-based application for analyzing mes-
sage frames on a DeviceNet network.
The DeviceNet Analyzer can display the message frames being transmitted
on a network and indicate traffic status. It can be used to find the source of
errors and for developing DeviceNet-compatible devices.
1-3 Scanner SDK Functions and Features
DeviceNet
Communications
Functions The Scanner SDK is equipped with the following communications functions.
• I/O communications functions that exchange I/O data with other
DeviceNet nodes:
DeviceNet Master function
DeviceNet Slave function
• DeviceNet explicit messaging functions (client and server functions)
In addition to the communications functions above, the Scanner SDK has a
status function that reads the status of the node (Master/Slave) and the net-
work and an error log function that records errors and their time of occur-
rence.
Note The DeviceNet network is capable of exchanging I/O with distant Slaves
through a single cable. Moreover, Slaves and other Masters can be controlled
and monitored by sending and receiving explicit messages. Refer to the
DeviceNet Operation Manual (W267) for more details.
In this manual, the “client” is the node that sends a message requesting ser-
vices and the “server” is the node that receives the message, performs the
requested processing, and returns a response.
DeviceNet
Communications Features The Scanner SDK has the following features:
Exchange I/O Data with DeviceNet Slaves
The status of I/O points on DeviceNet Slaves is mirrored in the DeviceNet PCI
Board. I/O can be performed with a specified Slave by calling the functions for
reading and writing I/O data.
