4 channels.
4 wire type.
Platinum resistance (Pt100, JPt100).
Conversion rate: 40ms/1 channel.
47 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 AJ71LP21G PDF.
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 AJ71LP21G
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 AJ71LP21G PDF.
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 requirrements,
Should consider the best performance to price ratio, a reasonable choice of PLC AJ71LP21G PDF AJ71LP21G Manual .
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 MITSUBISHI Reference Manual . 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 MITSUBISHI Reference Manual .
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 MITSUBISHI Reference Manual . Cable for unit load.
Length: 80mm.
Input / output unit standard equipment.
MITSUBISHI PLC program ssimulation debugging
The basic idea of program simulation debugging is,
In order to facilitate the form of simulation to generate the actual state of the scene,
Create the necessary environmental conditions for the operation of thee program AJ71LP21G Manual AJ71LP21G Reference Manual .
Depending on the way the field signals are generated,
The simulation debugging has two forms of hardware simulation and software simulation.
