(control algorithm subroutines), in addition to the base specified in IEC 61131 3 standard

In addition to this content, many powerful and strictly tested function blocks from practical engineering applications are also expanded. Any complex control

All schemes can be realized by the combination of these function blocks.

The function blocks provided by the system mainly fall into the following categories:

Analog quantity processing

Digital quantity processing

Loop adjustment

Logical sequence control

Logical operation

Monitoring function

Acquisition function

Arithmetic operation

Tcp/ip protocol communication interface

Modbus protocol communication interface

1ec870-5 protocol communication interface (telecontrol)

4.2 field controller PS

Industrial ial “field controller PS is a special process control station, which is embedded with a fieldbus communication interface for users to use

Fieldbus technology provides a very flexible choice. Each PS is allowed to insert 4 fieldbus interface cards (card types can be 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:

Flexible: it supports all international standard open fieldbus and can be mixed

4 high-speed fieldbuses can be connected at the same time (max. 12 MBD)

Simple project: only use the same tool CBF (control build f) software for configuration, debugging and diagnosis

mouth

Access to all information from the site, including equipment management information

Global database of Fieldbus equipment, control level and HMI (human-machine interface)

Module identification with production operating parameters

Complete self diagnosis

Compact and rugged design
