5.2.1.6 Data Flow
This section describes the flow of data blocks between the ControlLogix processor and
the remote server. Ladder logic in the ControlLogix processor is responsible for
generating requests and parsing messages received from the server. The parsed data
from the received messages are placed in the controller tags of the processor.
The following illustration shows the data flow for a request message:
The ladder logic determines when a request message is to be built. This request can be
triggered by an external or internal event in the processor. It is the responsibility of the
application engineer to construct ladder logic for each request message to be sent to the
remote server.
