The function blocks provided by the system mainly include the following categories: o Analog processing o digital processing loop regulation Logical sequence control c logic operation Monitoring function Collection function. c arithmetic operations c TCP/IP protocol communication interface Modbus protocol communication interface 1EC870-5 protocol communication interface (Telecontrol) 4.2 Field Controller PS Industrial” field…
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 media (RJ45 twisted pair, thin, thick or fiber optic cables and mixed media) and network topology can…
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:…
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…
the PS is used to receive process signals from the rack mounted i/0 modules supported by the PS. Each field controller PS can only be configured -Block fi810f card. — The two fi810f interface cards on the redundant PS. can be switched redundantly. S800 and S900 are distributed i/0 for process control stations. They communicate…
