Schneider Electric TMSES4 Ethernet Smart Module

Schneider Electric's TMSES4 Ethernet Smart Communication Module is a four‑port Ethernet interface for the Modicon M262 family, enabling networked communication for the TM3/5 I/O ecosystem. It provides four RJ45 Ethernet ports with 10/100/1000 Mbps support and auto‑negotiation, and includes MDIO auto‑crossover to simplify cabling without the need for a dedicated Ethernet switch. The module draws about 200 mA (7.85 W) and weighs roughly 403 g, and is installed to the left of the controller or after another TMSES4 expansion, with a right‑hand bus connector to the controller and a left‑side connector to additional TMSES4 modules. Note that TMSES4 is not a standalone Ethernet switch; it is a smart module within Schneider Electric's TMS ecosystem designed to enable modular Ethernet and inter‑module communication.
