The main unit of the AS-i system
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 AX11C Manual AX11C
This phenomenon is called the I/O delay time effect.
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 AX11C Manual .
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. Cable length: 0.055 meters.
Extending cable to connect CPU main substrate and extended substrate,
According to the model can provide different cable length,
If you need to connect the AnN type expansion substrate is required,
Selection of A1SC05NB (A1SC07NB) cable AX11C Manual . Input and output points: 512 points.
Input / output data points: 512 points.
Program capacity: 14K.
Basic command processing speed (LD command) s:1.0.
Optical data communication line.
User program storage capacity: it is a measure of how much the user application can store the number of indicators MITSUBISHI I/O MODULE Manual .
Usually in words or K words as units. 16 bit binary number is a word,
Every 1024 words are 1K words MITSUBISHI I/O MODULE Manual . 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.
Integral type: the PLC components are installed together or a few pieces of printed circuit board,
And together with the poweer supply installed in the casing to form a single overall called the host or the basic unit, small, ultra small PLC using this structure MITSUBISHI I/O MODULE Manual AX11C User's Manual.
Modular: PLC is the basic components of a separate module.
Mediumm and large PLC used this way AX11C Manual . Easy maintenance. Cable length: 20 meters.
PC to GOT long distance connection cable.
For connection between GOT and GOT.
