For the first time, Iranian experts have updated a distributed control system (DCS) built by US industrial conglomerate Emerson Electric at a petrochemical plant in the southwestern port of Mahshahr.
Distributed control systems are computerized platforms for automated control and operation of a plant or industrial process, usually with many control loops, in which autonomous controllers are distributed throughout the system.
The Emerson DCS used at the Shahid Tondgooyan Petrochemical Company (STPC) was obsolete, which had caused major production problems at the plant’s PET 1 unit, the company said in a statement.
The US company’s refusal to cooperate and provide support because of the American sanctions prompted Iranian experts to revamp and update the system without laying off production units, it added.
