Master / local station sharing.
Corresponding Ver2 CC-Link.
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 Q173HCPU-T Programming Manual Q173HCPU-T
Even if the information reaches saturation, it will not affect the link scan time.
The QJ61BT11N module supports CC-Link version 1 and version 2, which can be used as a local station or master station module.Storage card protection for universal Q series CPU Q173HCPU-T Programming Manual.
Q3MEM-4MBS-SET/Q3MEM-8MBS-SET bundled products.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 Q173HCPU-T Programming Manual.
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 MITSUBISHI Q173HCPU-T Manual.
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 MITSUBISHI Q173HCPU-T Manual.
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 MITSUBISHI Q173HCPU-T Manual.
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 Q173HCPU-T Structured Text. e., the input / output response delay.
System program memory for storing system program,
Including management procedures, monitoring procedures, as well as the user program to do the compiler to compile the process of interpretation Q173HCPU-T Programming Manual.
Read only memory. Manufacturers use, content can not be changed, power does not disappear.
