QnA/ACPU bus connection.
2 joint.
Applicable models: A985 (-V) /975/970/960/956 (W) GOT. Input and output points: 512 points.
Input / output data points: 512 points A960GOT-EBA-EU PDF.
Program capacity: 14K.
Basic command processing speed (LD command) s:0.20.
Optical data communication line function (GI cable).
Integral type: the PLC components are installed together or a few pieces of printed circuit board,
And together with the power supply installed in the casing to form a single overall called the host or the basic unit, small, ultra small PLC using this structure
A960GOT-EBA-EU
Modular: PLC is the basic components of a separate module A960GOT-EBA-EU PDF.
Medium and large PLC used this way. Easy maintenance.
Each scanning process. Focus on the input signal sampling. Focus on the output signal to refresh.
Input refresh process. When the input port is closed,
Program in the implementation phase, the input end of a new state, the new state can not be read A960GOT-EBA-EU PDF.
Only when the program is scanned, the new state is read.
A scan cycle is divided into the input sample, the program execution, the output refresh.
The contents of the component image register are changed with the change of the execution of the program.
The length of the scan cycle is determined by the three MITSUBISHI Operating Manual.
CPU the speed of executing instructionss A960GOT-EBA-EU Manual.
Time of instruction.
Instruction count.
Due to the adoption of centralized sampling.
Centralized output mode.
There exist input / output hysteresis phenomena, i.e., the input / output response delay.
User program storage capacity: it is a measure of how much the user application can store the number of indicators MITSUBISHI Operating Manual.
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 MITSUBISHI Operating Manual. Timer / counter,
Shift instruction accounted for 2 words. Data operation instructions for 2~4. Twisted pair cable.
Single bus.
MELSECNET/B (remote I/O 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.
MITSUBISHI PLC initialization procedure. Affter 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 A960GOT-EBA-EU Operating Manual.
The main contents of the initialization program arre: 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 A960GOT-EBA-EU Manual. .
