subroutines), in addition to the basic ones specified in the IEC 61131 3 standard In addition to this content, many powerful and rigorously tested function blocks from actual engineering applications have been expanded. any complex control The scheme can be realized by the combination of these function blocks. The function blocks provided by the system…
industrial application practice, more than 1000 sets of application performance in China; 4. It has good openness, flexibility and scalability; Fifth, the project is easy, the interface is friendly, and the maintenance is simple; 2. Industria1″ system communication Industrial” system uses international standard industrial bus. Field controller supports Profibus, FF, ModBus, Can, etc. International standard…
process control stations. They communicate with their controllers 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…
are still It is designed by the industrial “unified tool control bui lder without additional software. The interface card can be configured redundantly (separated between each other Redundant basic unit pm802f) and can be plugged in and out and replaced online. Fi830f: PROFIBUS DP interface card, as the master station, can connect 126 PROFIBUS DP…
downloaded to the PS CPU through diginets and the first network card. After the field bus interface card is newly installed or replaced, the required group The status information will be automatically reloaded. The configuration results and real-time process data are stored in RAM, and ram is installed on the Ethernet network card or battery…
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…
