MITSUBISHI Q173CPUN MELSAP-L Manual Q173CPUN Programming Manual

Upgraded version.
Control axis: maximum 8 axes.
Peripheral I/F: by CPU PLC.
Manual pulse generator operation function: can use 3 sets of manual pulse generator.
Synchronous encoder operation function: can use 8 synchronous encoder.
CPU special high speed communication bus, each 0.88ms cycle can exchange 14K data word Q173CPUN MELSAP-L Manual Q173CPUN Programming Manual.
Exercise basic performance is about 2 times, sports SFC processing time is reduced by about 1/4 Q173CPUN
PLC interrupt program to achieve high-speed synchronization between multiple CPU.
Motion specific instruction5 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 Q173CPUN MELSAP-L Manual Q173CPUN 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.
Each scanning process Q173CPUN MELSAP-L Manual Q173CPUN 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 hyysteresis phenomena, i Q173CPUN MELSAP-L Manual Q173CPUN Programming Manual. 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 Q173CPUN MELSAP-L Manual Q173CPUN Programming Manual.
Read only memory. Manufacturers use, content can not be changed, power does not disappear.
