8 slots.
To install the power supply.
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 A2ACPUR21-S1 Common Instructions Manual A2ACPUR21-S1 Programming Manual .
So, sometimes also known as the order control A2ACPUR21-S1
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. 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 A2ACPUR21-S1 Common Instructions Manual A2ACPUR21-S1 Programming 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 A2ACPUR21-S1 Common Instructions Manual A2ACPUR21-S1 Programming 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. Description: supporting the use of AJ65BT-RPI-10A and AJ65BT-RPT-10B, support 156K/625K/2.5Mbps.
