6ED1055-1MB00-0BA2 New Original Siemens LOGO! Plc Programming Controller module

2. Key Selling Points

1. Dual High-Performance Communication Signal Board: A front-mounted signal board (SB) designed for Siemens S7-1200 PLCs, featuring two independent RS485 interfaces that significantly enhance the PLC's ability to communicate simultaneously with multiple serial devices.
2. Individually Configurable Dual Ports: Both RS485 ports can be independently configured with different communication parameters (e.g., baud rate, data bits, parity) and operating modes, enabling parallel communication with diverse devices such as drives, instruments, and HMIs for efficient and flexible networking.
3. Full MODBUS RTU Protocol Support: Each port supports MODBUS RTU master and slave modes, allowing seamless integration with third-party devices that use this standard protocol, ensuring fast data exchange and system interoperability.
4. Plug-and-Play, Space-Saving Installation: Plugs directly into the front SB slot of the S7-1200 CPU—no external power or wiring required. Preserves the right-side module slots, offering maximum space efficiency for compact control panel designs.
5. Enhanced System Integration Efficiency: Adds dual serial communication capability without increasing the number of modules, ideal for complex applications like multi-device communication, data acquisition, and distributed control—simplifying system architecture and reducing wiring costs.
