2 channels.
10/7kpps.
Count input signal: DC5/12/24V, 2-5mA.
External input: DC5V/DC12V/DC24V.
External output: Transistor (open collector) DC12/24V, 0.5A.
36 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 A1SJ71E71N-T User's Manual.
And then combine the data and the program with CPU A1SJ71E71N-T
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 A1SJ71E71N-T User's Manual.
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 A1SJ71E71N-T User's Manual.
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 digital signal.
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 arithmetic operations, user oriented instruction,
And through digital or analog input / output control of various types of machinery or production process. DC input points: 8 points.
Input voltage and current: 7mA, DC24V.
Response time: 10ms.
8 point /1 a public side.
Positive / negative sharing.
Output points: 8 points.
Output voltage and current: DC24V, 0.3A/1 point, 2.4A/1 common end.
Response time: 2ms.
8 point /1 a public side.
Output form: transistor output, leakage type.
34 point terminal station.
Number of stations: 2 stops.
According to the control requirements of the system, using the appropriate design method to design MITSUBISHI PLC program.
Procedures to meet the requirements of system control as the main line,
Write one by one to achieve the control function or the sub task of the program,
Gradually improve the functions specified by the system.
MITSUBISHI PLC detection, fault diagnosis and display and other procedures.
These procedures are relatively independent, generally in the basic completion of the program design and then add.
Hardware simulation method is to use a number of hardware equipment to simulate the generation of the signal,
The signals are connected to the input end of the PLC system in a hard wired way, and tthe timeliness is strong A1SJ71E71N-T Manual.
Software simulation method is in the MITSUBISHI PLC in the preparation of a set of simulation program,
The simulation provides the field signal, which is simple and easy to operate, but it is not easy too guarantee the timeliness A1SJ71E71N-T Manual.
Simulation of the process of debugging, debugging method can be used to segment, and the monitoring function of programmer.
