6. Ethernet Communications Settings

6.2. Example of Checking Connection

This document shows an example of a Structured Text (ST) program in which the Controller
executes the connect processing, send/receive processing, and close processing on the RFID
Reader/Writer.
The Controller and RFID Reader/Writer send and receive the message of “GETR TYP FWV
(read the product type and firmware version of the memory data)”. The following figure
outlines the operation.
