ABB MSR04XI is a high-performance serial communication module designed for industrial automation systems.It is suitable for data interaction between SC300E control systems and remote devices that comply with the RS232-C standard.The following is a comprehensive overview of its core functions and technical features:
I.Core functions and application scenarios
Communication interface
-Provides 4 standard RS232 communication ports(ports 0-3),supporting 9600 or 19200 baud rates,of which port 0 is dedicated to software loading and diagnostic monitoring between the system processor and the workstation.
-The fifth port is only used for diagnostic purposes to ensure real-time visibility of module status.
System integration requirements
-Must be installed in slot 10 of the SC300E main rack to achieve basic communication functions between the system processor and the workstation.
-Other additional modules can be installed in other I/O slots,and mechanical coding blocks are used to prevent incorrect slot positions.
Industrial reliability design
-Triple voting technology:using circuit triple redundancy and voting procedures,with single-point fault tolerance to ensure system stability.
-Optical isolation protection:The communication port is isolated from the module circuit through an optical isolator,supporting 1kV voltage isolation and enhancing anti-interference performance.
-Environmental adaptability:The operating temperature range is-25°C to+70°C,and the storage temperature can reach-30°C to+80°C,meeting the needs of complex industrial environments.
