6DD1660-0BA0

Overview

6DD1660-0BA0 is a Siemens fiber-optic cable subrack coupling module (CS12–CS22) designed for L- and C bus connections, enabling point-to-point fiber-optic communication with synchronization and interrupt transfer capabilities.

Connectivity

• Maximum cable length: 200 m (point-to-point)

• Bus connections: L- and C bus

• Restriction: Not intended for use in SR6(V), as data transfer is only realized via C bus

Performance

• Data transfer time (normal load): ~5 µs per 16-bit value

• Data transfer time (high load): Max. ~32 µs per 16-bit value

Memory

• RAM on CS12: 128 KB

Signal Transfer (Master to Slave)

• Basic sampling time: Synchronizes the slave

• Alarm interrupt: Calls an interrupt task

• Clock interrupt: Sets the real-time clock
