complex control The scheme can be realized by the combination of these function blocks. 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…
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 rate can be as high as 12Mb. Profibus is used to connect intelligent devices such as distributed I/0 stations and field bus…
configuration language is based on the IE061131 3 industry standard, providing 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…
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 PS can only be configured -Block fi810f…
interface replacement card 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…

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, and then the calculation results are passed The fieldbus interface card returns the corresponding fieldbus actuator. Two field controllers can realize controller 1:1 redundancy, and undisturbed switching between master…
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 standard open fieldbus and can be mixed…
pair, thin cable, thick cable or optical fiber cable and mixed media) and network topology can be selected for the system bus Due to the adoption of tcp/ip protocol, the system can also realize ultra long distance communication with the help of public telephone network (dial-up mode) or satellite. PLC and other subsystems communicate with…
