Odot ODOT-S2/S4E2-4 - Bringing Modbus devices cleanly into the Ethernet
Many automation systems use field devices with Modbus RTU or ASCII via serial interfaces (RS232/RS485). These tried-and-tested devices are often difficult to address directly in modern, Ethernet-based control and IT environments (e.g. SCADA, MES, IoT gateways) because the serial interface is not easily accessible to network devices.
The Odot ODOT-S4E2-4 provides a remedy here: it converts serial Modbus RTU/ASCII communication into Modbus TCP and thus enables direct access to field devices via Ethernet networks - without additional software gateways or PLC code adaptations.
The gateways can address several serial RS-485 buses and bring their participants into the network via two LAN ports.
Typical application situations:
-
Retrofitting serial Modbus sensors or counters in Ethernet-based SCADA/MES systems
-
Retrofit projects with step-by-step modernization of the network infrastructure
-
Remote access to field devices via TCP/IP networks
-
Reduction of outdated serial connections in favor of standardized Ethernet communication
The S4E2-4 works as a transparent protocol converter with a stable Modbus TCP connection, supports multiple simultaneous connections and can be configured via a web interface. It therefore offers a pragmatic, economical solution for integrating existing Modbus RTU/ASCII devices into modern automation and IT processes.
