MITSUBISHI A1SD51S Command Manual A1SD51S Programming Manual
Product model: A1SD51S
Name: Corresponding Intelligent Communication Module
Brand: MITSUBISHI
Sort: Command Programming Manual
File language: English
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.
In addition to supporting the MODBUS protocol, these components also support the standard dedicated communication protocol for A1SJ71UC24 components A1SD51S Command Manual A1SD51S Programming Manual A1SD51S
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.
Two transmission modes: RTU or ASCII. Input points: 32 points.
Voltage: AC200 ~ 240V.
Current: 10mA A1SD51S Command Manual A1SD51S Programming Manual.
Response time: 25ms.
32 points / a common end..
38 point terminal station.
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.
Read only memory. Manufacturers use, content can not be changed, power does not disappear.
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 A1SD51S Command Manual A1SD51S Programming Manual.
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 control requirements,
Should consider the best performance to price ratio, a reasonable choice of PLC.
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 changeed with the change of the execution of the program A1SD51S Command Manual A1SD51S Programming Manual.
The length of the scan cycle is determined by the three.
CPU the speed of executing instructions.
Time of instruction.
Instruction count.
Due to thhe adoption of centralized sampling A1SD51S Command Manual A1SD51S Programming Manual.
Centralized output mode.
There exist input / output hysteresis phenomena, i.e., the input / output response delay.
