function blocks from practical engineering applications are also expanded. Any complex control All schemes can be realized by the combination of these function blocks. The function blocks provided by the system mainly fall into the following categories: o Analog quantity processing o Digital quantity processing Loop adjustment Logical sequence control c Logical operation Monitoring function…
supports PROFIBUS, FF, MODBUS, can and other countries International standard fieldbus, PROFIBUS is the most widely used open fieldbus international standard in the world, which is divided into FMS, DP and pa Level III, DP communication rate can be up to 12MB. PROFIBUS is used to connect distributed i/0 stations, field bus instruments and other…
configuration modes. The system contains about 220 functions The algorithm library of energy block, the basic library with more than 200 graphic symbols and the extended library with a large number of 3D symbols. The system uses the same set of configuration tool software to complete the configuration and commissioning of process level, operation level…
the operation management level and the process control level is realized by the di ginets network (Industrial Ethernet /iee802.3 standard), The user can select the communication transmission medium (ordinary cable or optical fiber) and network topology structure according to the actual situation of the application. Popular PC and MS_ Wi ndows2000 has been widely used…
function is realized Can (operate and display, print, trend display and alarm), and also complete system hardware diagnosis and data exchange between different systems Yes. The process 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…
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 the world. Line international standard, divided…
analog loop regulation capability of DCS Power-friendly human-machine interface (HMI) and convenient 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…
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 created. Moreover, both variables and process points can…
process control stations connected to I/O units. you can choose this Some process stations are in redundant mode (CPU redundancy, fieldbus module redundancy redundant) or non-redundant mode. Modular pluggable input/output modules Blocks are freely selected and used according to the type and number of system process signals. AC800F controller connects remote I/O or field device…
pairing dialog box to design the configuration window for these devices. ●Profibus field controller can be integrated through FDT/DTM technology line equipment system structure The Freelance 800F process control system is divided into operator levels and process control level. The operator level contains controls for operation and display. Archiving and logging, trending and alarming functions.…
