EXAMPLE
The following example will set the Operate Mode of input 1 of the Sensor module to
Invert the signal before transmitting it on DeviceNet. See the lineup established in Figure
3.1.
Once again we will use the same steps as in the above example to obtain the values of the
Class, Instance, and Attributes for the following
In the above screen, “Data sent” should be “1”.
Make the desired changes. In this example, to set the Operate Mode of input 1 of the
Sensor to Invert before transmitting, click the
([HFXWH button. This procedure can be
repeated for all of the presence sensing instances.
DeviceNet Explicit Messaging
The above configuration of the I/O module parameters is an example of explicit messaging.
DeviceNet Explicit Messages are generally used to configure a DeviceNet device.
Configuration tools such as the “DeviceNet Manager” or “RSNetworx” use explicit messages
when communicating with a device. Some tools, such as Rockwell Software’s “RSServer for
DeviceNet” use explicit messages to help build custom DeviceNet system user interfaces for
a PC. When using such a tool, it is often useful to be able to control the outputs of the
Modular DSA system and also read the status information and the inputs of the
