Built-in TCP/IP Protocol Stack Lightens Development Load
TCP/IPプロトコルスタックを内蔵する事で、ホストCPU側のシステムを大幅に変更する事なく、PLC経由でネットワークに接続可能。
また、WEBサーバとして、状態確認の他、遠隔制御する様なアプリケーションの構築が可能です。
Incorporating the TCP/IP protocol stack enables connection to a network via PLC
without requiring significant modifications to the host CPU system. Configuration of
a variety of remote control applications is also possible in addition to status
confirmation when used as a web server.
