High reliability, strict industrial application practice, and application performance of more than 1000 sets…
configuration language is based on ie0611313 industrial standard and provides function block diagram (FBD) and ladder diagram (LD), instruction list (IL), sequential function diagram (SFC), structured text (st) and other graphical configuration modes. The system contains about 220 functions The algorithm library of energy block, the basic library with more than 200 graphic symbols and…
control level realizes various loop adjustments including complex control (various PID, ratio, Simith, etc.) and high-speed logic control Control, sequence control and batch intermittent control functions. The internal communication of the process control station (between the controller and various intelligent devices such as i/0 or field instruments) adopts the international standard field general Line. The…
such as I/0 or field instruments) adopts the international standard field controller. Wire. The field controller supports various field buses such as Profibus. Profibus is the most widely used open field bus in the world. Line international standard, divided into FMS, DP Industrial “is a world leading all-round comprehensive open control system launched by the…
engineering software, and at the same time have high-speed logic and sequence control equivalent to high-end PLC indicators. control performance. The system can be connected to both conventional I/0 and various field bus devices such as Profibus, FF, CAN, and Modbus. system tool It has a high degree of flexibility and excellent scalability, whether it…
output, internal variables) ● Process point list (function block) ●Graphics ●Program Because the database is system-wide. The data only needs to enter a times, to avoid possible errors caused by multiple configurations. Project database files can be easily archived or backed up. When programmed by the user, a list of variables and labels is automatically…
operating system. DigiVis supports dual-screen display operation operating technology, that is to say, two operations can be performed using one PC station and operate with a mouse and a keyboard. Operator level can install one engineering station and several operators stand. ControlBuilderF engineering station configures and adjusts the system Mode. Usually, we can use portable…
data between the process control station and the operator station According to 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…
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…
