Vben the computer Is unavailable, the unit shall be safely operib from the central control center. 1.210 A computer system consisting of a "central" computer with facilities for receiving inforation from and transmitting data to the "block" (unit process control) computer will be provided. The block computer will perform functions per taining to data acquisition, unit control (set-point control and some direct digital control) and communication only. $je central computer will perform all major calculations such as equipment regulation, optimization and management information functions for the block computer. 1.220 The block computer will be located in the central control center. The central computer will be located in another area of the plant and will be shared by block computers for other process units. 1.230 When the block-central computer system is "on-line", all new program development will be accomplished on the central computer through the use of an "on-line" compiler or assembler. The central computer shall have the ability to compile and assemble programs for the block computers. A stable and reliable source of a.empower will be provided for this unit and will permit all critical process variables to remain active even though the main source of unit power is interrupted. See Section 3*000. All control systems shall be designed for fail-safe shutdown operation, both on power failure, instrument air failure, and combinations of both. Most electronic Instruments will be manufactured by the Foz'boro Company, xne majority of the control wives will be purchased from Famine1-Dahl or approved equal.
