MITSUBISHI AJ35PTC-CNV-SI PDF datasheet Melsecnet module datasheet PDF catalog

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 AJ35PTC-CNV-SI PDF catalog AJ35PTC-CNV-SI
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. Remote I/O controller, coaxial cable.
How to choose MITSUBISHI PLC AJ35PTC-CNV-SI PDF catalog.
MITSUBISHI PLC options include the choice of MITSUBISHI PLC models, capacity, I/O module, power, etc..
MITSUBISHI PLC distribution I/O points and design MITSUBISHI PLC peripheral hardware circuit
Draw the I/O point of the PLC and the input / output device connection diagram or the corresponding table,
This part also can be carried out in second steps.
Design PLC peripheral hardware circuit AJ35PTC-CNV-SI PDF catalog.
Draw the electrical wiring diagram of the other parts of the system,
Including the main circuit and the control circuit does not enter the PLC, etc..
The electrical schematic diagram of the system composed of I/O PLC connection diagram and PLC peripheral electrical circuit diagram MITSUBISHI Melsecnet module PDF catalog.
So far the system''s hardware electrical circuit has been determined. Input points: 32 points MITSUBISHI Melsecnet module PDF catalog.
Voltage: DC5/12/24V.
Current: 2.5/5mA.
Response time: 3ms.
8 points / a common end.
Positive / negative sharing.
38 point terminal station.
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 MITSUBISHI Melsecnet module PDF catalog.
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 control requiremeents,
Should consider the best performance to price ratio, a reasonable choice of PLC AJ35PTC-CNV-SI PDF datasheet.
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 AJ35PTC-CNV-SI PDF catalog.
Read only memory. Manufacturers use, content can not be changed, power does not disappear.
