operator levels and process control level. The operator level contains controls for operation and display. Archiving and logging, trending and alarming functions. Controller executes open loop and closed loop control function. Freelance 800F DigiVis Operator Level DigiVis operator stations use PC hardware, either standard commercial Business PCs can also be industrial-grade PCs and run on…
communication. For field devices, process control stations and operator stations, a unified global database is used for the entire control system, thereby reducing cost and time investment in establishing data communication and interactive access. And ensure the consistency of data throughout the system. ●Provide system-wide unified inspection of user applications, overriding from process control…
speaking, a self The engineering application software cost of the automation project accounts for about the entire project. About 50%, it is not difficult to see that the migration of cost structure creates a lot of innovation for users. Create an opportunity to optimize project investment, therefore, it is necessary to start from engineering programming…
Glossary Process station: This term is used to describe AC800F controllers (field controllers) and rack-mounted controllers. A process station can be designed to be redundant configuration and non-redundant configuration. AC800F : This term is used to describe the AC800F Field Controller type of process station. A redundant process station consists of 2 AC800F controller. Rack…
communication interface (Telecontrol) 4.2 Field Controller PS Industrial” field controller PS is a special process control station, which is embedded with field bus communication interface for users to use Fieldbus technology offers very flexible options. Each PS allows to insert 4 fieldbus interface cards (the card type can be different), Each card is connected to…
the public telephone network (dial-up mode) or satellite to achieve ultra-long-distance communication. Subsystems such as PLC communicate with the Industrial” system through the ModBus protocol interface. The system also supports IEC870-5 over-control protocol. discussion. The Flash EPROM inside the PS provides more than 220 functional modules (control algorithm subroutines), in addition to the basic…
