MITSUBISHI A9GT-QCNB User's 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.
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 A9GT-QCNB A9GT-QCNB
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 A9GT-QCNB .
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 A9GT-QCNB . 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.
Output type: transistor output, drain type.
Output points: 16 points.
OFF leakage current: 0.1mA.
Output protection function: No.
Rated load voltage / current: DC12V/DC24V/0.5A.
External connection: 2 wire.
Spring clip terminal.
Do not need to be tightened further or locked with screws, which can reduce the working hours of wiring.
Using 2 pieces of structure of the terminal units, maintenance can be maintained in the same line under the condition of the replacement module.
When installing the module can choose to use the DIN guide rail or screw mounting.
Can be used for the 3 wire sensor input wiring. 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. Afteer 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 A9GT-QCNB User's 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 A9GT-QCNB User's Manual. .
