External input / output interface unitBy MELSECNET/B I/O can be decentralized control.
In a main PLC station this module can control up to 512 I/O points.
The popularization and application of PLC programming has been developed rapidly in our country,
It has been widely used in all kinds of mechanical equipment and production process of electrical control devices,
All walks of life have emerged a large number of application of PLC transformation of the results of the equipment A970GOT-TBD-B Operating Manual A970GOT-TBD-B
Understand the working principle of PLC, have the ability to design, debug and maintain the PLC control system,
Has become the basic requirements of modern industry for electrical technicians and engineering students A970GOT-TBD-B Operating Manual.
The instruction list programming language is a programming language similar to assembly language mnemonic,
As well as assembly language by the operation code and the number of operations.
In the case of the computer for the PLC handheld programmer compile user program.
At the same time, the programming language of the instruction list corresponds to the ladder diagram programming language,
In PLC programming software can be converted to each other A970GOT-TBD-B Operating Manual. Figure 3 is the instruction sheet corresponding to the ladder diagram of figure 2PLC.
The characteristics of instruction table programming language is used to represent mnemonic operation function,
Easy to remember, easy to grasp;
In the handheld programmer on the keyboard using the mnemonic representation, easy to operate, can be programmed in computer;
There is a one-to-one correspondence between the ladder diagram and the ladder diagram. Its characteristics are basically consistent with the ladder diagram language. Input type: DC input, positive public end / negative public end.
Input points: 32 points.
Enter the response time: 1.5ms the following.
Rated input voltage / current: DC24V/5mA.
External connection: 1 wire.
40 pin connector type (FCN connector type).
Through the 40 pin connector type (FCN connector type) can be connected to a variety of devices.
Can be installed along the 6 direction.
MITSUBISHI PLC program simuulation debugging
The basic idea of program simulation debugging is,
In order to facilitate the form of simulation to generate the actual state of the scene,
Create the necessary environmental conditions for the operation of thee program A970GOT-TBD-B Manual A970GOT-TBD-B Manual.
Depending on the way the field signals are generated,
The simulation debugging has two forms of hardware simulation and software simulation.
