Maintenance information

Processor Module (CP461): Two modules incase of a dual-redundant configuration

On-line replacement of CP471 in dual-redundant configuration can be performed by the user. • For replacement of existing CP461 with CP471. 1. Software version of Control Function for Field Control Station must be R6.05 or later. 2. The style code of ESB bus coupler module EC401 which is used together with CP471 must be S3 or later. 3. Replacement from CP461 to CP471 is prohibited to perform by a user. Replacement work must be done by the service engineer authorized by Yokogawa Electric Corporation. 4. CP471 can not be co-existed with CP461 in dual-redundant configuration. However, a pair of CP461 in dual-redundant configuration can be on-line replaced with a pair of CP471. 5. Existing CP471 must not be replaced with CP461.

Replacement Condition

Replacement from CP461 to CP471 is prohibited to perform by a user. This replacement must be done by the service engineer authorized by Yokogawa Electric Corporation. CP471 can be combined with the style code S3 or later of ESB bus coupler module EC401. See GS 33J60E30-01EN

CP471 operates with CENTUM VP R6.01 or later version of Control Function for Field Control Station. Be sure to apply the software patch for supporting CP471 for CENTUM VP R6.01, R6.02, R6.03, and R6.04. CP471 can be combined with the style code S3 or later of ESB bus coupler module EC401. See GS 33J60E30-01EN. *2: Select the option code “/MRN” if A2FV50 with marine standards is required. *3: Unavailable for ordering A2FV50S with CP461 due to the supply ends on October 19, 2019.
