QA1S65B | MITSUBISHI Old small A series expansion substrate QA1S65B

SRAM+E2PROM memory card.
RAM capacity: 512KB.
E2PROM capacity: 512KB. PCI bus /PCI-X bus.
Support Japanese, English OS.
Multimode fiber optic cable.
Dual loop controller network (control station / common station).
DB A20 AnyWire system uses a separate transmission mode,
Sensor networks to achieve high speed and high reliability QA1S65B.
Thee transmission distance of 50m/200m/1km/3km can be selected.
1 modules can be up to 512 points of the input, 512 points of output (standard setting) QA1S65B.
Even branch wiring, but also to detect transmission lines.
Province distribution network module in cabinet and device.
Link to connect the 64 stations when the fastest scanning time for 1 MITSUBISHI QA1S65B.2ms (rate 2.5Mbps).
According to the transmission distance, the transmission rate is selected from 2 QA1S65B.5Mbps, 625kbps and 156kbps.
CC-Link/LT from the station does not need any parameter settings.
Only need to set up the transmission speed in the master module, you can use the remote I/O MITSUBISHI QA1S65B.
I/O control in the first class of open field network module.
CC-Link based on reliable field bus technology,
Able to transmit large number of bits data (such as ON/OFF information) and word data (such as analog information).
Consistency of CC-Link to maintain loop transmission,
And the cycle of transmission and information (instantaneous transmission) communication separately, so as to ensure the timeliness of MITSUBISHI QA1S65B.
Even if the information reaches saturation, it will not affect the link scan time.8 slots.
Requires 1 power modules.
Used to install the old section of the large A series PLC module.
Switch volume control is designed to,
According to the current input combination of the switch quantity and the history of the input sequence,
So that PLC generates the corresponding switching output,
In order to make the system work in a certain order.
So, sometimes also known as the order control.
And sequential control is divided into manual, semi-automatic or automatic.
And the control principle is decentralized, centralized and hybrid control three.
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.
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.
System program memory for storing system proogram,
Including management procedures, monitoring procedures, as well as the user program to do the compiler to compile the process of interpretation QA1S65B.
Read only memory. Manufacturers use, content can not be changed, power does not disappear.
