Polled - the master initiates communication by sending its polled I/O
message to the board. The board consumes the message, updates any
outputs and produces a response containing the input data.
Change-of-State - a production occurs when an input changes. A
heartbeat production occurs if no input condition change occurs within the
expected packet rate. This heartbeat production tells the master that the
board is alive and ready to communicate. Consumption occurs when data
changes and the master produces new output data to the board.
Refer to the table below for the word/bit definitions:
Configure the Parameters
The 1799 I/O boards have eight parameters that are configurable through a
DeviceNet software configuration tool like RSNetWorx for DeviceNet. The
DeviceNet configuration tools require an Electronic Data Sheet (EDS) for
the 1799 I/O boards in order to configure the module’s parameters. The
EDS file can be found at the ODVA Web site (http://www.odva.org).
Use the descriptions in the table below to help you configure the
parameters.

Parameter
Description
Baud Rate
Controls the board’s data rate.
Auto-Baud
Enables the board to match the network’s data rate. When enabled,
Baud Rate parameter is ignored.
Input Off-to-On
Filter Time
Controls the amount of time the input must be in the ‘on’ state
before the board reports the input as ‘on.’
Input On-to-Off
Filter Time
Controls the amount of time the input must be in the ‘off’ state
before the board reports the input as ‘off.’
Output Idle State
Controls the state of each output when the DeviceNet master is in
an idle state.
