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…
marked Chi. Industrial” DCS system design purpose: the most economical engineering investment, the most powerful control function. Five features of Industria1″ DCS system: 1. All-round integrated control system, integrating DCS & PLC & Field Bus; 2. Using RISC SuperScalar high-speed CPU, with super performance; Three high reliability, strict industrial application practice, more than 1000 sets…
topology according to the actual situation of the application. The popular PC and MS_ Windows 2000 have been widely used in various fields all over the world, becoming the de facto standard computer platform. tower. The operating station 0S, the engineering station ES and the data gateway GS of the Industrial” system use this platform…
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 IART protocol or field bus (31. 25Kb ProfibusPA and FF bus). The system communication between the operation management level and the process control level is realized by Di giNetS network…
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 the PS. Each field controller…
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 slave stations, and the communication rate can reach 12mbd One PS can…
card provides communication with the system network diginet s (iee802.3 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…
