protocol communication interface (Telecontrol) 4.2 Field Controller PS Industrial” field controller PS is a special process control station, which is embedded with field bus communication interface for users to use Fieldbus technology offers very flexible options. Each PS allows to insert 4 fieldbus interface cards (the card type can be different), Each card is connected…
telephone network (dial-up mode) or satellite to achieve ultra-long-distance communication. Subsystems such as PLC communicate with the Industrial” system through the ModBus protocol interface. The system also supports IEC870-5 over-control protocol. discussion. The Flash EPROM inside the PS provides more than 220 functional modules (control algorithm subroutines), in addition to the basic ones specified in…
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 fieldbus, Profibus is the most widely used open fieldbus international standard in the world, divided into FMS, DP and PA Level 3, DP communication…
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: the most economical engineering investment, the most powerful control function. Five features of Industria1″ DCS system: 1. All-round…
giNetS network (Industrial Ethernet/IEEE802.3 standard), Users can choose the communication transmission medium (ordinary cable or optical fiber) and network 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…
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 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…
