27 Modicon M221, M241 and M251 logic controllers The embedded Ethernet communication ports in Modicon M221, M241 or M251 logic controllers and in the Modicon TM4ES4 communication module optimize integration in factory network architectures. Modicon M221, M241 and M251 controllers can easily be integrated in typical architectures: v machine to devices (variable speed drives, remote I/O modules, operator dialogue terminals) with the I/O Scanner function v machine to machine with the NGVL function v machine to supervision with the Modbus Client/Server function and EtherNet/IP adapter Ethernet also brings transparency to the factory, in particular - thanks to the firewall functions - making it possible from any point on the network to safely: v program, monitor a controller or download an application v access device parameters (variable speed drives for example) A simple web browser can be used to access machines anytime anywhere, using a tablet or smartphone, for example, using the web servers embedded in Modicon M241 and M251 controllers. Safety can be enhanced by the use of VPN modems; refer to our Partner program on our website > Products and Services > Automation and Control > Collaborative Automation Partner Program.
