Memory card interface (AD59-MEF), parallel interface.
On-line debugging is the process that will through the simulation debugging to further carry on the on-line unification to adjust.
On-line debugging process should be step by step,
From MITSUBISHI PLC only connected to the input device, and then connect the output device, and then connect to the actual load and so on and so on sstep by step AX81B.
If you do not meet the requirements, the hardware and procedures for adjustment.
Usually only need to modify the part of the program can be AX81B. Number of channels: 2 channels.
Sensing methods and temperature range: R, K, J, T, S, B, E, N, U, L, PL, II,, Wre5-26,,, and.
A1S64TC series component is a kind of temperature controller combined with ANS series CPU.
Components with temperature measurement input and built-in PID algorithm control output, can be used in a variety of temperature control occasions AX81B.
Each component controls up to 4 loops at most.
Thermocouple input or PT100 3 wire temperature sensor input.
Control output switching signal for the output of the transistor MITSUBISHI AX81B.
BW is a signal with broken line detection function.
Input points: 32 points.
Voltage: DC24V.
Current: 7mA (external switch ON) /1.5mA (external switch OFF).
Response time: 10ms.
32 points / a common end.
Positive / negative sharing.
38 point terminal station MITSUBISHI AX81B.
Disconnection detection function.
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 MITSUBISHI AX81B.
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 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 changed with the change of the execution of the program.
The length of the scan cycle is determined by the three.
CPU the speed oof executing instructions AX81B.
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.
