ControlNet-to-DeviceNet Linking Device

25

1788-5.2B - October 1999

Controller Interface

The initial release of the 1788-CN2DN firmware supports a single default input, 
output, and status assembly over the ControlNet backplane. These default I/O 
structures were created to reduce the complexity of connecting DeviceNet I/O 
and status data with ladder programs. The module creates all 3 structures whether 
or not DeviceNet nodes are configured or online.

The RSNetWorx for DeviceNet software application configures scanlist map 
segments that are used to copy specific portions of I/O data between the I/O 
structures and DeviceNet network packets.

Output Structure

The controller controls output I/O by writing output data to an output structure in 
the 1788-CN2DN module. The scanner module then delivers a copy of these 
output values to modules on DeviceNet. The output structure consists of two 
32-bit control registers and an array of 1 to 123 32-bit words for output data.

The output structure consists of these data regions:
