Honeywell PKS system (1)

The PKS (Process Knowledge System) system is an automation system that unifies the business information system and the production process control system of the entire factory on one platform. It inherits the advantages of the traditional DCS and at the same time integrates new technological breakthroughs. It is a set of comparisons. TPS and PlantScape systems are becoming more complete control systems.

Features of PKS system

Openness

The standard industrial Ethernet network used by the PKS system is the factory information network, which is the most widely used Ethernet in the field of office automation. The STATION omni-directional operation station in the PKS system provides a standard Ethernet interface, which makes the whole plant management and control integration easy. STATION workstation uses WINDOWS 2000 as the operating platform, and PKS is designed as a working mode in which the lower-level controller CPM reads server data through SQL database and then conducts two-way communication with STATION workstation. Both the server and the workstation run in the WINDOWS 2000 environment, which has more functions of the WINDOWS operating system. The CONTROL NET communication network of the PKS system adopts ISO802.4 formulated by ISO (International Organization for Standardization) and IEEE802. 4 open system interconnection standards formulated by IEEE (American Institute of Electrical and Electronics Engineers), and adopts ISO's seven-layer OSI model. As the basis, follow the MPA (Factory Automation Protocol) network standard, token bus network communication. Any computer equipped with PKS system Station version software can be connected to a standard Ethernet switch interface through a network cable to become a Station workstation.

Openness does have many benefits, but while considering openness, the security and reliability of the system must first be fully considered. The loss caused by the breakdown of the production process or the accident may be much higher than the cost saved by the open choice of products. At the same time, note that when selecting system equipment, first determine the requirements of the system, and then select the necessary equipment according to the requirements. Try not to equip some unnecessary functions, especially the selection of network functions and peripherals must be cautious. For example, when we choose to open the network, the possibility of being attacked by viruses or hackers will increase; we choose a wealth of peripherals such as optical drives or floppy drives, and the USB interface provides operators with loading irrelevant software (such as games, etc.) Opportunity to wait. These will lead to system paralysis or other fatal failures.
