MITSUBISHI A68AD-S2 User's Manual A/D converter module Manual

16 channels.
DC-10 ~ 10V, DC-20 ~ 20mA.
38 point terminal station.
How to determine the input / output device of MITSUBISHI plc.
According to the control requirements of the system,
All input devices and output devices required for the determination of the system,
To determine the input / output device related to the MITSUBISHI PLC,
To determine the I/O PLC points A68AD-S2 Manual .
Detailed analysis of the process and work characteristics of the controlled object,
To understand the coordination between the controlled object machine, electricity and liquid,
The control requirements of the controlled object for MITSUBISHI PLC control system are put forward,
Determine the control program, to develop a design task book A68AD-S2 Manual A68AD-S2 Output type: transistor output, source.
Output points: 16 points.
OFF leakage current: 0.1mA.
Output protection function.
Rated load voltage / current: DC24V/DC24V/0.1A.
External connection: 3 wire.
Sensor connector type (E-CON type).
Using industry standard E-CON type.
Simple wiring through sensor connector.
When installing the module can choose to use the DIN guide rail or screw mounting A68AD-S2 Manual .
3 wire sensor input. Enter points: 64 points.
Voltage: DC12/24V.
Current: 3/7mA.
Response time: 10ms.
32 points / a common end.
Cathode common.
40 pin connector.
High speed input.
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 A/D converter module Manual .
Read only memory. Manufacturers use, content can not be changed, power does not disappear MITSUBISHI A/D converter module Manual .
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 MITSUBISHI A/D converter module Manual . 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 coomponent image register are changed with the change of the execution of the program A68AD-S2 User's 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 A68AD-S2 Manual .
Centralized output mode.
There exist input / output hysteresis phenomena, i.e., the input / output response delay.
