following components: Basic unit pm802f Power supply sa801f/sd802f o Ethernet network card ei801f/ei802f/ei803f o Fieldbus interface card fi810f/fi820f/fi830f Various accessories The main components of the field controller PS are described below. Basic unit pm802f The basic unit pm802f is composed of a metal rack and a CPU motherboard. It periodically scans the data from the…
flexible choice. Each PS is allowed to insert 4 fieldbus interface cards (card types can be different), Each card is connected to a fieldbus to collect process data and diagnostic information from the bus. The interface card is easy to replace and plug and play (plug & play) and can be plugged in and out…
communication rate can be up to 12MB. PROFIBUS is used to connect distributed i/0 stations, field bus instruments and other intelligent devices. The communication among process station, operator station and engineer station is realized through the system bus diginets (Industrial Ethernet). user Different transmission media (RJ45 twisted pair, thin cable, thick cable or optical fiber…
instruments is through IART protocol or fieldbus (31.25kb profibuspa and FF Bus). The system communication between 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…
with the field equipment maintenance management and cross plant production management control applications As an important member of industrial “family, AC800F system fully embodies industrial” initiated and led by ABB in technology Information technology) a new trend. The system is divided into two levels: operation management level and process control level. At the operation management…
data exchange between different systems. can. The process control stage 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)…
complex 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…
database for management. ● List of all variables (input, 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…
engineering station and several operators stand. ControlBuilderF engineering station configures and adjusts the system Mode. Usually, we can use portable devices such as notebooks to The system is now 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…
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. Controller executes open loop and closed loop control function.…
