10BASE2.
For Q mode.
Control layer /MELSECNET/10 (H) is the middle layer of the whole network system,
Control network which is convenient and high speed processing data transmission between PLC, CNC and other control equipment A2NCPUP21-S1 PDF.
As MELSEC control network MELSECNET/10,
With its good real-time performance, simple network settings, no procedures of the network data sharing concept,
As well as the redundant circuit and so on, has obtained the very high market appraisal,
The number of devices to reach the highest in japan,
In the world is also one of the few A2NCPUP21-S1
And MELSECNET/H not only inherited the excellent characteristics of MELSECNET/10,
Also makes the network real-time bbetter, more data capacity,
Further adapt to the needs of the market A2NCPUP21-S1 PDF A2NCPUP21-S1 Manual . Input and output points: 480 points.
Program capacity: 7K step.
Basic command processing speed: 4.4 ~ 5.6us.
Power supply: input DC5V output 2A DC24V/.
Modular: PLC is the basic components of a separate module A2NCPUP21-S1 PDF.
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 MITSUBISHI Programming Manual.
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 MITSUBISHI Programming Manual.
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 applicaation can store the number of indicators A2NCPUP21-S1 Programming Manual.
Usually in words or K words as units. 16 bit binary number is a word,
Every 1024 words are 1K words MITSUBISHI Programming Manual. PLC to store instructions and data in words.
General llogical operation instructions each account for 1 words A2NCPUP21-S1 Manual . Timer / counter,
Shift instruction accounted for 2 words. Data operation instructions for 2~4.
