Description
Output Points: 32 Points. Voltage: DC5/12V. Output Type: Sink Type. Response Time: 1ms. 16 Points / A Common End, 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. 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 execting 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 requirements, Should consider the best performance to price ratio, a reasonable choice of PLC. 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. 3C-2V/5C-2V coaxial cable. Double loop. PC inter network (management station / common station) / remote I/O network (remote control station). 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 MITSUBISHI AY71 AY71 Design PLC peripheral hardware circuit. 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 MITSUBISHI AY71. The electrical schematic diagram of the system composed of I/O PLC connection diagram and PLC peripheral electrical circuit diagram. So far the system''s hardware electrical circuit has been determined. 8 channels. 3 wire platinum measuring antibodies (Pt100, JPt100). Transform speed: 40ms/1 channel. 38 point terminal station. Input status and input information input from the input interface, CPU will be stored in the working data memory or in the input image register MITSUBISHI AY71. And then combine the data and the program with CPU. The result is stored in the output image register or the working data memory, And then output to the output interface, control the external drive. 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. The working process of the input interface circuit: when the switch is closed, the diode light, The transistor is then guided to the internal circuit and input signal under the irradiation of the light. When the switch is off, the diode does not emit light, and the transistor is not on the way. Internal circuit input signal. It is through the input interface circuit to the external switch signal into PLC internal can accept the ddigital signal AY71. MITSUBISHI PLC is the main product in the production of MITSUBISHI motor in Dalian. It uses a kind of programmable memory for its internal storage procedures, Execute logic operation, sequence control, timing, counting and arithhmetic operations, user oriented instruction, And through digital or analog input / output control of various types of machinery or production process AY71.. Mitsubishi. Mitsubishi Electric Corporation. AY71.
