Input points: 32 points.
Enter the response time: 1.5ms the following.
Rated input voltage / current: DC24V/4mA.
By embedding the product into the customer base, the remote I/O station can be simply developed A1NCPUP21 Programming Manual .
Mitsubishi Co PLC network inherited the traditional use of the MELSEC network,
And make it better in terms of performance, function, easy to use etc A1NCPUP21.
Provides a layer of three layers of clear network, to provide the most suitable network products for a variety of uses.
The information layer /Ethernet (Ethernet) information layer is the highest level of the network system,
Mainly in the PLC, the device controller and production management with PC transmission between production management information, quality management information and the operation of equipment, etc A1NCPUP21 Programming Manual . ,
Information layer using the most common Ethernet.
It is not only able to connect the PC system UNIX, windows system, etc.,
And can connect a variety of FA devices A1NCPUP21 Programming Manual .
The Ethernet module has the function of Internet e-mail receiving and sending,
The user can send and receive the production information conveniently in any place of the world,
Build a remote monitoring management system MITSUBISHI A1NCPUP21 Manual.
At the same time, the use of the Internet FTP server functions and MELSEC protocol can be very easy to achieve the program upload / download and transfer of information MITSUBISHI A1NCPUP21 Manual. 5 slots.
To install the power supply.
For QnA/A series.
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 MITSUBISHI A1NCPUP21 Manual.
So, sometimes also known as the order control.
And sequential control is divided into manual, semi-automatic or automatic.
And the control principle is decentralized, centralized and hybrid control three.
Each scanning process. Focus on the input signal sampling. Focus on the output signal to refresh.
Input refresh process. When the input port is closed,
Program in the implementation phase, the input end of a new state, the new state can not be read.
Only when the program is scanned, the new state is read.
A scan cycle is divided into the input sample, the program execution, the output refresh.
The contents of the component image register are changed with the change of the execution of the program.
The length of the scan cycle is determined by the three.
CPU the speed of executing instructions.
Time of instruction.
Instruction count.
Due to the adoption of centralized sampling.
Centralized output mode.
There eexist input / output hysteresis phenomena, i A1NCPUP21 Common Instructions. e., the input / output response delay.
System program memory for storing system program,
Including management procedures, monitoring procedures, as well as the user program tto do the compiler to compile the process of interpretation A1NCPUP21 Programming Manual .
Read only memory. Manufacturers use, content can not be changed, power does not disappear.
