MELSECNET/10, MELSECNET/H coaxial, input voltage: AC100-240V.RS-232 2 channel.
Transfer speed: 0.3-19.2kbps.
Input status and input information input from the input interface,
CPU will be stored in the working data memory or in the input image register.
And then combine the data and the program with CPU MITSUBISHI A970GOT-TBD User's Manual.
The result is stored in the output image register or the working data memory,
And then output to the output interface, control the external drive A970GOT-TBD
Semiconductor circuit with memory function.
System program memory and user memory.
System program memory for storing system program,
Including management procedures, monitoring procedures, as well as the user program to do the compiler to compile the process of interpretation MITSUBISHI A970GOT-TBD User's Manual.
Read only memory. Manufacturers use, content can not be changed, power does not disappear. Input type: DC input, negative public end.
Input points: 16 points.
Enter the response time: 1.5ms the following.
Rated input voltage / current: DC24V/7mA.
External connection: 2~4 line type.
Waterproof connector type.
Strong waterproof type of IP67 protection grade.
No need to stop the system can be replaced module MITSUBISHI A970GOT-TBD User's Manual.
Without the use of tools can be a simple connection, save time.
Terminal resistor built-in.
Can be installed along the 6 direction.
Hardware simulation method is to use a number of hardware equipment to simulate the generation of the signal,
The signals are connected to the input end of the PLC system in a hard wired way, and the timeliness is strong.
Software simulation method is in the MITSUBISHI PLC in the preparation of a set of simulation program,
The simulation provides the field signal, which is simple and easy to operate, but it is not easy to guarantee the timeliness.
Simulation of the process of debugging, debugging method can be used to segment, and the monitoring function of programmer. 2 slots.
No need to install power.
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.
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 moode A970GOT-TBD Manual.
There exist input / output hysteresis phenomena, i.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 A970GOT-TBD Manual.
