in IEC 61131 3 standard In addition to this content, many powerful and strictly tested 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…
flexibility and expansibility; 5、 Easy engineering, friendly interface and simple maintenance; 2. Industria1 “system communication Industrial ial “the system uses the international standard industrial bus. The field controller 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…
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 the extended library with a large…
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 control level is realized by the di ginets network (Industrial Ethernet /iee802.3 standard), The user can select the…
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 m anagement level and process control level. At the operation management level, not only the…
information technology) new trends. The system is divided into two levels: operation management level and process control level. At the operation management level, not only the traditional control system monitoring operation function is realized function (operation and display, printing, trend display and alarm), and also complete system hardware diagnosis and data exchange between different systems.…
divided into FMS, DP and PA Level 3, DP communication rate can be as high as 12Mb. Profibus is used to connect intelligent devices such as distributed I/0 stations and field bus instruments. Communication between the process station, operator station and engineering station takes place via the system bus DigiNetS (Industrial Ethernet). user Different transmission…
system can be expanded. The hardware of the system control station is encapsulated in an all-metal shell, which can withstand the most Harsh industrial environment. The device can be installed either in a cabinet or on a wall. System complies with all current EMC standards and is CE marked Chi. Industrial” DCS system design purpose:…
ES and the data gateway GS of the Industrial” system use this platform to ensure the system’s Versatility, openness and ease of use, and bring great convenience to future technical upgrades and maintenance. System engineering is very convenient. The configuration language is based on the IE061131 3 industry standard, providing function block diagram (FBD), ladder…
through Prof ibusdp Fieldbus Communication, which can be installed in the controland PA three levels, DP communication rate can be as high as 12Mb. The CAN (DIN/IS011898 standard) bus The biggest feature is its super sturdiness and data security. The system of course also supports Modbus. The communication with the intelligent field instrument is through…
