MITSUBISHI A1SJ71QE71N-T

SRAM memory card.
RAM capacity: 128KB. Protocol: SLMP, TCP/IP, UDP.
Communication mode: full duplex / half duplex.
At the same time can open a few: 4 connection.
Weight: 0.3kg.
Connect PLC FX3U/FX3UC to Ethernet.
Support fixed buffer storage, communication connection MELSOFT, through the MC communication protocol, e-mail messages .
When connected to the MELSOFT, through the Works2 PLC can achieve the remote maintenance of GX program A1SJ71QE71N-T
Connecting FX3UC, FX3GC requires FX2NC-CNV-IF or FX3UC-IPS-5V. 5 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 A1SJ71QE71N-T.
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 A1SJ71QE71N-T.
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 ceentralized sampling A1SJ71QE71N-T.
Ceentralized output mode .
There exist input / output hysteresis phenomena, i.e., the input / output response delay.
System program memory for storing system program,
Including management procedures, monitoring procedures, as well as the user program too do the compiler to compile the process of interpretation A1SJ71QE71N-T.
Read only memory. Manufacturers use, content can not be changed, power does not disappear.
