GI-50/125 optical cable.
Double ring.
PLC to PLC network (control station / common station) / remote I/O network / (remote master station).
MELSECNET/H network module capable of composing large scale flexible network system.
The MELSECNET/H network system includes the PLC network of the control station and the communication between the stations and the remote I/O network in the remote station remote I/O station HC-SF352B
Optical fiber loop system...... High speed communication of 10Mbps/25Mbps is realized.
The distance between stations, the length of the total cable length, strong anti-interference.
Coaxial bus system...... Using low cost coaxial cable, the network construction cost is lower than that of the optical fiber loop network.
Twisted pair bus system...... Combined with high performance price ratio network module and twisted pair cable,
The construction cost of network system is very low.MITSUBISHI motor universal AC servo amplifier MELSERVO-J3 series.
Rated output: 0.75kw.
Interface type: SSCNET type III fiber communication.
Special specification: suitable for direct drive servo motor.
Power specification: single phase AC200V.
Direct drive system suitable for high speed and high precision!
High speed operation can be realized by direct drive (2m/s), and the traditional mechanical transmission can not achieve such a high speed.
The full closed loop control can be realized by using the position feedback signal from the load side encoder, such as the linear encoder.
The use of a flexible linear servo motor drive components can make the system more compact structure.
The primary side of the linear servo motor (motor coil) is sliding along the secondary side (permanent magnet) of the motor,
So linear servo motor is especially suitable for large range of applications. In addition, linear servo motor can be connected in series,
Especially for large systems in two axes for high precision synchronous operation. 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.
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.
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.
