The scale of the system is highly scalable, and a single-system supports 1 to a maximum of 100 control stations and 100 operating stations. each control The station can support several thousand I/0 points at most, and…
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 operating station 0S, the engineering station ES and…
selected for different connection schemes, RS422, RS485, RS232. All interfaces are electrical 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…
fi830f/fi820f/fi810f Fieldbus interface cards are divided into several types according to different protocol standards. Each interface card provides – a fieldbus interface (PROFIBUS, Can, FF, MODBUS, etc.). The configuration and parameter settings of the interface card itself and the field instrument (or remote i1/0) on the connected fieldbus are still It is designed by the…

Time required to process 1000 IL (instructions): < 1.0 ms…
Redundant communication link (diginetr) to ensure information synchronization between master and slave PS. — However, the master PS fails, and the slave PS can quickly and undisturbed connect the replacement worker Make. All inputs and outputs also support redundant operation. The data communication between the field process controller PS. operating station 0s and the engineer…
25KBd Foundation Fieldbus H2 (fast Ethernet) HART The system allows different types of field buses to be mixed and run simultaneously in the same field controller PS. Industrial “field control explosion (AC800F) consists of the following components: Basic unit pm802f Power supply sa801f/sd802f Ethernet network card ei801f/ei802f/ei803f o Fieldbus interface card fi810f/fi820f/fi830f Various accessories The…
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 with power. The field controller PS has the following features: o Flexible: it supports all international…
public telephone network (dial-up mode) or satellite. PLC and other subsystems communicate with industrial “system through Modbus protocol interface. The system also supports iec870-5 over control coordination Discussion. The flash EPROM inside PS provides more than 220 function modules (control algorithm subroutines), in addition to the base specified in IEC 61131 3 standard In…
