2 slots.
No need to install power.
For QnA/A series.
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 A0J2-E56DR Manual A0J2-E56DR User's Manual.
So, sometimes also known as the order control.
And sequential control is divided into manual, semi-automatic or automatic A0J2-E56DR
And the control principle is decentralized, centralized and hybrid control three.
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 A0J2-E56DR Manual A0J2-E56DR User's 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.
CPU the speed of executing instructions A0J2-E56DR Manual A0J2-E56DR User's Manual.
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.
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.
Read only memory. Manufacturers use, content can not be changed, power does not disappear. For A6TBXE/A6TBY36E/A6TBX54E/A6TBY54E/A6TBX70E (common cathode; source) long 1m.RS-232C connection (micro computer connection).
Built in clock function.
Applicable models: A985 (-V) /975/970/960GOT. Input type: DC input, negative public end.
Input points: 16 points.
Enter the response time: 1.5ms the following.
Rated input voltage / current: DC24V/6mA.
External connection: 3 wire.
Spring clamping terminal platform push type input module.
Input module with diagnostic function
The use of pushh type, do not need screw fastening, so can reduce the wiring hours A0J2-E56DR Manual A0J2-E56DR User's Manual.
Can be used for each 1 points to enter the wiring of the broken wire detection.
Wiring abnormality of external power supply can be confiirmed A0J2-E56DR Manual A0J2-E56DR User's Manual.
Using 2 pieces of structure of the terminal units, maintenance can be maintained in the same line under the condition of the replacement module.
