10Mbps transmission speed, the computer as the support of the flexible manufacturing system at the plant level, the requirements of more and more data flow,
High transmission speed can be guaranteed to increase the amount of transmitted data while maintaining the minimum time to transfer and receive data between programmable controllers A1SC07B MITSUBISHI.
The response time of PLC is the interval between the time of the change of the external output signal of the PLC and the time of the change of the external output signal which is controlled by it,
Lag time, this is the time constant of the input circuit,
The time constant of the output circuit, the arrangement of the user statement and the use of the instruction,
The cycle scan mode of PLC and the way of PLC to refresh the I/O and so on A1SC07B MITSUBISHI A1SC07B
This phenomenon is called the I/O delay time effect.
Switch volume control is designed to,
According to the current input combination of the switch quantity and the history of the input sequence,
So that PLC generates the corresponding switching output,
In order to make the system work in a certain order.
So, sometimes also known as the order control A1SC07B MITSUBISHI.
And sequential control is divided into manual, semi-automatic or automatic.
And the control principle is decentralized, centralized and hybrid control three. Cable length: 0.055 meters.
Extending cable to connect CPU main substrate and extended substrate,
According to the model can provide different cable length,
If you need to connect the AnN type expansion substrate is required,
Selection of A1SC05NB (A1SC07NB) cable. Three remote components can be connected to the CC-LINK system.
Remote I/O: refers to the field components that require only ON/OFF control,
Such as digital I/O or pneumatic valve, etc..
In this type of communication can only be carried out in the bit data.
Remote components: the field components that require processing of register data,
For example analog I/O and counter, etc..
In this type of component, in addition to the bit data can be carried out in the register data communication.
Intelligent remote: this type of element refers to the actions that allow the master station or other station to access,
To collect data and control the local PLC station,
GOTS and programmer interface unit are of this type.
PLC is the use of " sequential scanning, and constantly circulating " way to work.
That is, in the operation of CPU, PLC according to the user according to the control requirements of the coexistence of the user in the memory of the program,
According to the instruction sequence number (or address number) for periodic cyclic scan, such as no jump instruction,
From the first instruction to the user program execution sequence one by one, until the end of the program,
And then return to the first command, start the next round of the new scan, in the process of each scan,
Also complete the sampling of the input signal and the output status of the refresh and other work.
