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…
communication rate can be as high as 12MB. Can (din/is011898 standard) bus The biggest feature is its super robustness and data security. The system also supports MODBUS. The communication with intelligent field instruments is through IART protocol or fieldbus (31.25kb profibuspa and FF Bus). The system communication between the operation management level and the process…
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 controller. Wire. The field controller supports various field buses such as Profibus. Profibus is the most widely used open field bus in…
Modbus. system tool It has a high degree of flexibility and excellent scalability, whether it is the control of small production units, or the control of ultra-large-scale whole plants – integrated control, even The Industrial” system can handle the application of field equipment maintenance management and cross-plant production management control with ease. An important member…
from manufacture all the way to service. ABB automation early In 1990, it obtained the DQS certificate based on ISO9001 certification, EQnet quality based on ISO 9000/EN 29000 was subsequently achieved Certification. However, the Freelance 800F is more than technical excellence, I We have also spent a lot of effort in proper planning, installation and…
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 created. Moreover, both variables and process points can be opened and…
connects remote I/O or field device via fieldbus ready. system communication Communication between operator level and process control level using TCP/IP Protocol system bus (based on Ethernet), you can choose different transmission medium such as AUI, twisted pair, fiber optic or coaxial cable. Freelance OPC server for connecting to higher-level operators station (800xA) or other…
configured in the office and on site. Operator-level PC Can also be used as an engineer station. Engineer standing during system uptime Intervals can be closed without a permanent connection to the system. Freelance 800F Process Control Stage At the process control level, the Freelance 800F system can be controlled by It consists of a…
