DeltaV system with 7 Operator stations and 3 other stations for development, applications and engineering.
Five independent process areas each one controlled by a 140CPU67160 Quantum hot standby redundant PLC. Controllers communicate with DeltaV MD redundant processors using Ethernet redundant communications.
Two remote process areas controlled by 140CPU53414A/U and 140CPU67160 Quantum PLCs, with wireless Ethernet communication with the main system for monitoring and remote access to ladder logic. Each area is locally operated using a Magelis XBTG7340.
Main electrical substation protections system controlled by a 140CPU43412A/U Quantum PLC and a Magelis XBTG7340 operator terminal.
One mobile unit controlled with a M340 BMXP341000 PLC with Modbus Plus communication with the main system using a BM85 gateway
RIO network for IO acquisition connecting an average of 10 drops per process area, with approximately 5,000 discrete IO points an 1,000 analog signals.
Modbus Plus network with 5 operator terminals Magelis XBTG7340 and XBTGT5230.
2 Softstart units Altistar 48 model ATS48C41Y, drives Altivar 28 and Altivar 31
Scope
The scope of services our company provided was:
Recollection of detailed technical information of the existing systems.
Control architecture design based on our clients standard definitions.
Definition of required control and communications equipment, along with an estimate of the number of control enclosures to be used.
Detailed control engineering diagrams generation including materials listings, scope of installation work and design calculations datasheets.
Control enclosures diagrams for its construction, assembly and internal wiring.
Control enclosures acceptance test before shipping.
PLC, DeltaV and operator terminals configuration and programming.
Configuration of intermediate devices such as Ethernet TCP/IP switches, MB+/MB gateways, MB+ and RIO repeaters.
Electrical installation of the control and communications systems.
Simulation of the final code looking for approval by the people responsible of maintenance and operation in the area, using the appropriate simulation equipment.
Obsolete existing control enclosures replacement with new ones, including its connection.
Network communications commissioning including Ethernet, MB+, RIO and wireless Ethernet.
Field devices commissioning. Process equipment testing without materials and in full production. Control loops tuning and timers adjustment.
24 / 7 support after full production start to ensure continuous operation for each area.
At the end of the strat-up, temporary fully-updated documentation was delivered to the customer and a later time was replaced by the final as built information.
