M-CBI by MERMEC STE (COMPACT SIS 4) is a modular and scalable platform ideally suited for small to large applications. It has been designed for all types of rail traffic, with stations of several sizes and it provides the availability required by the Infrastructure Managers. The modular hardware and software operate reliably with minimum maintenance needs. M-CBI includes a fully redundant interlocking computer and duplicated transmission and communication units. It satisfies the requirements for Safety Integrity Level 4 (SIL4) in the CENELEC standards. M-CBI includes a Central Post where the Vital Nucleus, HMI, and communication board towards other systems (CTC, RBC, other CBI) are equipped and Peripheral Posts containing Object Controllers as much as needed to manage the specific outside plant layout. The whole system is kept under control by mean a web based diagnostic system. Host of different functions are available on single platform:
- Designed to increase system availability and simplify installation and maintenance
- User-programmable application logic using application and simulation tools
- Suitable for harsh environments
- ETCS lev.1 functions can be fully integrated in the system.
