3C-2V/5C-2V coaxial cable.
Double circuit.
MELSECNET (II) (Master / local station).
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
MR-J3-10BS1
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.
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.. Input / output points: 4096 points.
Number of input and output elements: 8192.
Program capacity: 60 K step.
Processing speed: 0.0095 s.
Program memory capacity: 240 KB.
Support USB and RS232.
Support installed memory card.
Providing high speed communication between multiple CPU.
High speed and high precision data processing.
The processing speed of the real number (floating point) arithmetic has been greatly improved,
Addition instruction reached 0.014 mu s,
Therefore, it can support the request of high-speed, high-precision processing data processing.
In addition, the new addition of double precision floating point arithmetic instructions,
Simplify the programming, reduces the computational error when executing complex formula.
Shorten the fixed scan interrupt time, high precision device.
The minimum interval of the fixed period interrupt program is reduced to 100 s.
The high speed signal can be accurately obtained, which makes the contribution to the higher precision of the device.Input and output points: 480 points.
Program capacity: 7K step.
Basic command processing speed: 4.4 ~ 5.6us.
Power supply: input DAC100 ~ 120/200 ~ 240V/ output 2A DC24V, 0.5A DC5V.
Optical data communication line.
Modular: PLC is the basic components of a separate module.
Medium and large PLC used this way. Easy maintenance.
Relay output interface circuit of PLC
Working process: when the internal circuit output digital signal 1,
There is a current flowing through, the relay coil has a current, and then the normally open contact is closed,
Provide load current and voltage.
When the internal circuit outputs a digital signal 0, there is no current flowing through it,
The relay coil does not have a current, and the normally open contact is broken off,
A current or voltage that is disconnected from the load.
It is through the output interface circuit to the internal digital circuit into a signal to make the load action or not action.
User program storage capacity: it is a measure of how much the user application can store the number of indicators.
Usually in words or K words as units. 16 bit binary number is a word,
Every 1024 words are 1K words. PLC to store instructions and data in words.
General logical operation instructions each account for 1 words. Timer / counter,
Shift instruction accounted for 2 words. Data operation instructions for 2~4.
