controller.
Box Description
➊ Format the required data and set up the ladder logic program to send an Explicit Message Request to the
scanner or bridge module (download).
➋ The scanner or bridge module transmits the Explicit Message Request to the slave device over the
EtherNet/IP network.
➌ The slave device transmits the Explicit Message Response back to the scanner. The data is stored in the
scanner buffer.
➍ The controller retrieves the Explicit Message Response from the scanner’s buffer (upload).
➎ The Explicit Message is complete.
