ABB GJV3074321R302

2.Product application and characteristics

Application field:This product may belong to PLC(programmable logic controller)module card,which is widely used in industrial automation control systems.

Functional characteristics:According to the general characteristics of PLC,GJV3074321R302 may have the following functional characteristics:

Interrupt processing:Supports the execution of interrupt programs,and can call corresponding interrupt programs according to preset interrupt events(or interrupt trigger conditions).The selection of interrupt events is usually within the range specified by the PLC and cannot be arbitrarily written by the user.

Structured programming:Allowing different interrupt events to call the same interrupt program,this action is similar to structured programming,which helps to improve programming efficiency and code maintainability.

Time priority principle:When multiple interrupt events do not occur at the same time,the PLC follows the principle of”time priority”and processes the interrupt event that occurs first.

Interrupt priority:During the execution of an interrupt program by the PLC,if multiple interrupt events occur consecutively or at the same time before the execution of the interrupt program,the PLC will identify their importance and process the important interrupt events first,while the remaining interrupt events will be”queued”.

The company mainly imports PLC modules,programmable controllers,servo control systems and DCS spare parts,such as:ABB,AB(Rockwell),GE(General Electric),Bentley,Honeywell Er),Emerson.),Motorola,Invensys,Westinghouse,etc.The company has established close cooperative relations with many world-renowned PLC and DCS product maintenance service providers.We can purchase goods directly from abroad and provide equipment and spare parts from different countries and manufacturers.
