Foxboro Evo ™ Standard 200 Series Baseplates（PSS 31H-2SBASPLT）

The standard 200 series substrate is Foxboro Evo ™ The core functions of the "hardware connection center" of the system include:
Module carrying and positioning: providing standardized slots for adaptation Field Control Processor（FCP）、Field Device Controller（FDC）、Field Communications Module（FCM）、Fieldbus Module（FBM） Waiting for multiple types of modules to achieve modular layout;
Signal and power distribution: Built in 2 Mbps HDLC redundant serial bus (Module Fieldbus), responsible for data exchange between modules; Simultaneously provide 24V DC redundant power interface to provide stable power supply for all mounted modules;
Redundancy and Scalability Support: Compatible with module level redundancy (such as FCP/FDC redundancy pairs), and supports online addition of substrates (requiring redundant buses) to meet system expansion requirements;
Compatibility Connection: Downward compatible with 100 Series FBM (requiring 268 Kbps fieldbus), upward compatible with Foxboro Evo control network, achieving smooth transition between old and new systems.
