MITSUBISHI AX40-UL User's Manual PDF

Data format: ASCII.
Data bits: 7.
A1SJ71UC24-R2-S2 and A1SJ71UC24-R4-S2 allow the Ans series PLC to be connected to the MODBUS network,
As the network from the station, and in accordance with the instructions of the main station of the CPU Ans user storage area for data reading / writing AX40-UL PDF.
In addition to supporting the MODBUS protocol, these components also support the standard dedicated communication protocol for A1SJ71UC24 components AX40-UL
This feature makes the main station of the data acquisition and control with more flexibility.
Support MODBUS slave station protocol.
Supports 1 to 21 function code AX40-UL PDF.
Two transmission modes: RTU or ASCII. RS-232 1 channel.
RS-422/485 1 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 AX40-UL PDF.
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.
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 User's Manual.
Read only memory. Manufacturers use, content can not be changed, power does not disappear. Input points: 16 points.
Voltage: DC12/24V.
Current: 4/10mA.
Response time: 6ms/1ms (high speed mode) MITSUBISHI User's Manual.
8 points / a common end.
Negative utility.
20 point terminal station.
Each scanning process. Focus on the input signal sampling. Focus on the output signal to refresh.
Input refresh proocess AX40-UL Manual. 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 MITSUBISHI User's Manual.
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 exist input / output hysteresis phenomena, i.e., the input / output response delay.
PLC selection with the development of PLC technology, more and more types of PLC products,
Function is becoming more and more perfect, and its application is more and more extensive.
Different series of different models of PLC has different performance, applicable occasions also have different emphasis,
Price also has a greater difference. Therefore PLC selection,
Under the premise of meeting the contrrol requirements,
Should consider the best performance to price ratio, a reasonable choice of PLC AX40-UL User's Manual.
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 AX40-UL Manual.
