function block diagram (FBD), ladder diagram (LD), instruction list (IL), sequential function chart (SFC), structured text (ST) and other graphical configuration methods. The system contains about 220 functions Algorithm library for energy blocks and a basic library with more than 200 graphic symbols and an extended library with a large number of 3D symbols. The…
isolation Away. And the redundant operation is realized by two redundant field controllers. Fi8i0f card is a triple can bus protocol interface card (rate 1mbd) used to connect industrial ial “conventional process control station The i/0 protection unit of the PS is used to receive process signals from the rack mounted i/0 modules supported by…
Ethernet standard) Interface. Basic characteristics: 1ee802.3 Ethernet standard o Ei801f provides 10base2 thin cable communication interface Ei802f provides 10BASE5 thick cable connection (through AUI interface) Ei803f provides 10Base-T twisted pair communication interface 32-bit data bus, 100 mb/s DMA (direct memory access) mode main memory ram, corresponding CPU operating load <4% Optional ram backup battery Fieldbus…
configuration and PS The user program is 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…
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 The signals of the field bus sensors are processed according to the control application program configured by the user,…
Fieldbus technology provides a very 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…
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 intelligent devices. The communication among process station, operator station and engineer station is realized through the system bus diginets…
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 and even fieldbus instruments, and uses the same A global database. 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 communication transmission medium (ordinary cable or optical fiber) and network…
system can connect not only conventional i/0, but also PROFIBUS, FF, can, MODBUS and other field bus devices. System tool It has high flexibility and excellent scalability, whether it is the control of small-scale production devices or the large-scale integrated control of the whole plant, even The industrial “system can cope with the field equipment…
