Reader writer 1 channel connection, AnSCPU/QnASCPU.
PLC is the use of " sequential scanning, and constantly circulating " way to work.
That is, in the operation of CPU, PLC according to the user according to the control requirements of the coexistence of the user in the memory of the program,
According to the instruction sequence number (or address number) for periodic cyclic scan, such as no jump instruction,
From the first instruction to the user program execution sequence one by one, until the end of the program,
And then return to the first command, start the next round of the new scan, in the process of each scan,
Also complete the sampling of the input signal and the output status of the refresh and other work MITSUBISHI A0J2-56DT User's Manual MITSUBISHI A0J2-56DT User's Manual A0J2-56DT

Transmission speed: 2 channel total is 115.2kbps.
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.
As MELSEC control network MELSECNET/10,
With its good real-time performance, simple network settings, no procedures of the network dataa 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 A0J2-56DT Manual.
And MELSECNET/H not only inheritedd the excellent characteristics of MELSECNET/10,
Also makes the network real-time better, more data capacity,
Further adapt to the needs of the market A0J2-56DT Manual.
