3-2 Planning to Use Your ControlNet Adapter Module
Overview of Adapter
Operation Connections are established between a scanner and an adapter to exchange
input and output data on the network. Status information is transferred along
with the I/O data and status.
1747-ACN15/ACNR15 adapters support connections to individual modules
and rack connections to a group of modules. The adapters support multiple
rack and group connections to the same modules, as long as only one scanner
controls any module’s outputs. Up to 64 connections per adapter are possible
with 240 words (max) supported per connection. An adapter can control up to
30 slots of 1746 I/O (3 chassis max). The input data attributes correspond
directly to the read area of the I/O module’s data table image. The output
attributes correspond directly to the write area of the I/O module’s data table
image.
RSNetWorx is the software tool that is used to schedule network bandwidth
for all scheduled traffic originators that reside on a ControlNet network
segment. RSLinx is the communication software tool used by RSNetWorx to
access the ControlNet network. A 1784-KTCX15 PC card or 1784-PCC
ControlNet card can be used as the hardware interface to the network.
