I/O slots: 8 slots.
Outline dimension: 430*130.
CPU basic board can be plugged into 1 power modules,
1 CPU components and a maximum of 2, 3, 5, or 8 single slot size special function components and I/O components are respectively inserted and arranged A975GOT-TBD PDF.
Expansion ports are arranged on both sides of the base plate,
For connecting the expansion board for.
Up to 3 extension substrates A975GOT-TBD Input and output points: 2048 points.
Input / output data points: 2048 points.
Program capacity: 30K.
Basic command processing speed (LD command) s:0.15.
Optical data communication line.
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, ssmall, ultra small PLC using this structure A975GOT-TBD PDF A975GOT-TBD Manual.
Modular: PLC is the basic components of a separate module.
Medium and large PLC used this way A975GOT-TBD PDF. Easy maintenance.
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 Operating 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.
The length of the scan cycle is determined by the three MITSUBISHI Operating Manual.
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 a measure of how much the user appplication can store the number of indicators MITSUBISHI Operating Manual A975GOT-TBD Operating 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 A975GOT-TBD Manual. Timer / counter,
Shift instruction accounted for 2 words. Data operation instructions for 2~4.
