A/D, D/A arbitrary set of unified 4 channel resolution: 1/2000
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 AY41-UL 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
AY41-UL
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 AY41-UL PDF. Therefore PLC selection,
Under the premise of meeting the control requirements,
Should consider the best performance to price ratio, a reasonable choice of PLC AY41-UL PDF.
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 User's 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 iss the main product in the production of MITSUBISHI motor in Dalian AY41-UL 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 User's Manual. 3C-2V/5C-2V coaxial cable between the single bus PC network (control station / common station) / remote I/O network (remote master) MITSUBISHI User's Manual.
The response time of PLC is the interval between the time of the change of the external output signal of the PLC and the time of the change of the external output signal which is controlled by it,
Lag time, this is the time constant of the input circuit,
The time constant of the output circuit, the arrangement of the user statement and the use of the instruction,
The cycle scan mode of PLC and the way of PLC to refresh the I/O and so on.
This phenomenon is called the I/O delay time effect.
Switch volume control is designed to,
According to the current input combinnation of the switch quantity and the history of the input sequence,
So that PLC generates the corresponding switching output,
In order to make the system work in a certain order AY41-UL User's Manual.
So, sometimes also known as the order control.
And seqquential control is divided into manual, semi-automatic or automatic AY41-UL Manual.
And the control principle is decentralized, centralized and hybrid control three.
