Recently, the K201, K501 and K601 CCS control systems of Sino-Korean Petrochemical ethylene plants have completed the system rack and processor hardware upgrades as planned
.
The upgrade of the "three-machine" control system of the ethylene plant mainly includes the replacement and update of the system controller and supporting racks, the firmware version update of the TCM communication card and related IO cards, and the overall replacement of the workstation
.
The electrical instrument center strictly controls the quality acceptance work of the three-machine control system upgrade process, and checks and confirms multiple links from the controller to the IO card, the loop channel and the terminal block, and fundamentally guarantees the integrity and intrinsic safety of the control system.
, to lay a solid foundation for the long-term operation of the third ethylene unit
