Cable length: 30 meters.
For QCPU and GOT (need A9GT-QCNB) connection.
For the connection between GOT and GOT. Input type: DC input, positive common end.
Input points: 16 points.
Enter the response time: 1.5ms the following.
Rated input voltage / current: DC24V/5mA.
External connection: 3 wire.
Sensor connector type (E-CON type) MITSUBISHI A2NCPU Programming Manual.
Using industry standard E-CON type A2NCPU
Simple wiring through sensor connector.
When installing the module can choose to use the DIN guide rail or screw mounting.
3 wire sensor input. CC-Link (remote device station).
Twisted pair. Input and output points: 1024 points.
Input / output data points: 1024 points.
Program capacity: 14K.
Basic command processing speed (LD command) s:0 MITSUBISHI A2NCPU Programming Manual. 20.
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.
Modular: PLC is the basic components of a separate module.
Medium and large PLC used this way. Easy maintenance.
Each scanning process MITSUBISHI A2NCPU Programming Manual. 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.
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.
CPU the speed of executing instructions.
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 aa measure of how much the user application can store the number of indicators A2NCPU 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 llogical operation instructions each account for 1 words A2NCPU Manual . Timer / counter,
Shift instruction accounted for 2 words. Data operation instructions for 2~4.
