Schneider Electric Modicon Ethernet Switches are a networking infrastructure solution that provides optimization in network performance and improves plant productivity. These switches provide improved cybersecurity, simplified maintenance through a web interface or USB port, and designs for harsh environments and high temperatures. The Modicon switches feature easy interoperability with legacy systems, increased network reliability, PoE technology variant, and support internet protocols such as Modbus TCP and EtherNet/IP. The fiber optic adaptors are available in 1000BASE-TX/RJ45, 10/100 BASE-SX, 10/100 BASE-TX/RJ45, and 10/100 BASE-LX Ethernet ports. The MCSEAM0100 is a configuration backup key that is used to save and retrieve the switch configuration. The MCSESM devices provide very high operational reliability, long-term reliability and flexibility, and meet the relevant industry standards.
