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.
Read only memory. Manufacturers use, content can not be changed, power does not disappear IS74-2.2K-CHT
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 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. "Universal output function: source type.
Program capacity: 260K step.
Basic operations processing speed: 9.5ns.
Communication interface: USB/Ethernet (built-in CC-Link function).
Program capacity: 20K step.
Control mode: stored procedure repeated operation.
Input / output points: 4096 points.
End cap.
High precision PWM control of the highest 200kHz.
In the PWM output mode, by setting the ON time and cycle time,
The duty cycle can be changed, and the minimum cycle time is 5 s.
In addition to lighting dimming control, simple motor control and heater control,
Can also be used to require high resolution detection equipment, such as a wide range of oscillators.
CPU built-in functions can be easily set through programming tools.
The built-in I/O function settings can be easily carried out through the parameters of the programming tool.
5 s units can be used for high precision workpiece measurement in pulse measurement mode,
Can be used with a minimum of 5 s units of the input signal of the ON/OFF time (the shortest 200 s) for high precision measurement.
For example, after measuring the ON time of the sensor input,
The "moving speed" and "length" of the workpiece can be accurately calculated ". "
