MITSUBISHI PLC protection and chain procedures.
Protection and chain is an indispensable part of the program, must be carefully considered.
It can avoid the control logic confusion caused by illegal operations A1SJ71E71-B2--S3.
MITSUBISHI PLC initialization procedure. After MITSUBISHI PLC on power, the general need to do some of the initial operation,
In order to start making necessary preparations, to avoid the wrong operation of the system A1SJ71E71-B2-S3.
The main contents of the initialization program are: to some data area, counter and so on,
Data needed to restore some of the data area,
Set or reset some relays,
For some initial state display, etc A1SJ71E71-B2-S3..
MITSUBISHI PLC program simulation 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 the program.
Depending on the way the field signals are generated,
The simulation debugging has two forms of hardware simulation and software simulation MITSUBISHI A1SJ71E71-B2-S3. Video display function: NTSC / PAL input system, 4CH.
RGB display function: analog RGB input system, 1CH.
Applicable model: A985GOT-V.
Available network: 10BASE2 MITSUBISHI A1SJ71E71-B2-S3.
Max / total distance: 185/925m.
A1SJ71E71 is a compact Ethernet interface module,
Used to hang PLC series ANS to ethernet.
There are two kinds of hanging network modules: A1SJ71E71-B2-S3 and A1SJ71E71-B5-S3 respectively corresponding to 10BASE2 and 10BASE5,
So that the vast majority of installed cable can continue to use MITSUBISHI A1SJ71E71-B2-S3. Input type: DC input, positive common end.

Using industry standard E-CON type.
Simple wiring through sensor connector.
When installing the module can choose to use the DIN guide rail or screw mounting.
3 wire sensor input. 8 channels.
Input: DC-10 ~ 10V/DC4 ~ 20mA.
Output (resolution): -1000 ~ 1000, -2000 ~ 2000.
Transform speed: 2.5ms/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.
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 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 internall 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 A1SJ71E71-B2-S3.
