The Yokogawa SCP471 Processor Module is a crucial component in the CENTUM VP Distributed Control System (DCS), designed to manage control operations.

It serves as a replacement for the earlier CP461 model, offering improved functionality and better integration in systems requiring redundancy and high availability.

SCP471  Weight:Approx. 0.7 kg.

Memory Backup:

The SCP471 processor includes battery back-up to protect its memory for up to 72 hours during power failure.

Battery recharge time: Minimum 48 hours.

SCP471  Dual-redundant Vnet/IP interface: Ensures continuous communication even if one bus fails, providing redundancy in control communication.

The SCP471 can replace the CP461 module but must be supported with software version R5.01 or later of the CENTUM VP system.

The SCP471 ESB Bus Coupler must be Style code S3 or later for compatibility.

SCP471 cannot coexist with CP461 in a dual-redundant configuration.

Memory Protection: Equipped with a battery backup for main memory, capable of maintaining memory integrity for up to 72 hours during a power failure. The battery recharges within 48 hours.

SCP471  It supports dual-redundant Vnet/IP interfaces, ensuring robust and fail-safe communication between devices.
