Parallel printer connection (1CH).
Applicable models: A95_ (-M3) /A956WGOT. Output type: transistor drain.
Output points: 32 points.
Load voltage: DC5/12.
Load current: 0.016A.

Switching value, also known as logic, refers to only two values, 0 or 1, ON or OFF A950GOT-TBD Hardware Manual A950GOT-TBD User's Manual.
It is the most common control, it is the advantage of PLC control,
Is also the most basic application of PLC A950GOT-TBD
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 A950GOT-TBD Hardware Manual A950GOT-TBD User's Manual.
And sequential control is divided into manual, semi-automatic or automatic.
And the control principle is decentralized, centralized and hybrid control three. Input and output points: 1024 points.
Input / output data points: 1024 points.
Program capacity: 14K.
Basic command processing speed (LD command) s:0.20.
Optical data communication line.
Each scanning process. Focus on the input signal sampling A950GOT-TBD Hardware Manual A950GOT-TBD User's Manual. 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.
User program storage capacity: it is a measure of how much the user applicatiion can store the number of indicators A950GOT-TBD Hardware Manual A950GOT-TBD User's 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 A950GOT-TBD Hardware Manual A950GOT-TBD User's Manual. Timer / counter,
Shift instruction accounted for 2 words. Data operation instructions for 2~4.
