DCS System by Control Electric Company Private Limited

We offer a robust DCS System based on industrial Ethernet and PROFIBUS-DP fieldbus structure, with integration being based on the HART standard protocol's HAMS to centralise the on-site management of intelligent instruments.

It is able to easily integrate systems such as SIS, PLC, MES, and ERP, enabling seamless data communication between on-site intelligent instrument equipment, control system, and the ERP, creating a centrally controlled smart factory.

KEY FEATURES:

Full redundancy:System network, control network, controller, power modules, and I/O modules can be configured for redundancy, and do not have single-point faults.

Multiple isolations: Fiber-optic isolation is used between the system bus and modules; electric isolation is used between modules, and power isolation between site power supply and the system power supply.

Reliable design: The system is designed to be hardy in harsh industrial environments, equipped with anti-electromagnetic interference device that is compliant with IEC61000, and corrosion resistance that satisfies the G3 requirements under the ISA S71.04 standards.

Safety network: A reliable real-time Ethernet is used for the system’s network that is equipped with firewall-equipped switches. A PowerPC structured industrial chip that is inbuilt with anti-network storm components is used for the controller CPU.

Extensive diagnostics: The controller and I/O module is equipped with smart diagnostic units, and each module is capable of complete self-diagnosis and failure reporting for failure and statuses such as communication status, signal disconnection, short circuit, and over range.

Highly reliable design concept: Many safety system designs and concepts were adopted to make the system more reliable, such as determining signal quality bits, failure-oriented safety, and checksum of all data transmitted.

Flexible and open

• Supports 3 types of system network structures such as P-to-P (peer network), C/S (client / server), P-to-P and C/S (mixed).
• Supports industrial Ethernet with star, ring, and bus topology.
• Compatible with different types of fieldbuses, and supports protocols such as HART, PROFIBUS-DP, PROFIBUS-PA, and MODBUS. The HMI (human machine interface) is full of features, and the software is coded with control algorithms compliant with IEC61131-3 standards.
• Supports user-defined function modules and scripting languages.
• Able to flexibly modify control algorithms and hardware components, and download with ease on-site after modify without stopping.
• The system design takes into account the user’s ease of usage, maintenance, and replacement, while providing complete information on system status and diagnosis.
