MITSUBISHI A2ACPUP21-S4 Programming Manual (Dedicated Instructions) PDF

Input and output points: 512 points.
Input / output data points: 512 points.
Program capacity: 14K.
Basic command processing speed (LD command) s:1.0.
Optical data communication line function (GI cable) A2ACPUP21-S4 PDF.
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 A2ACPUP21-S4
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 A2ACPUP21-S4 PDF.
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 A2ACPUP21-S4 PDF.
There exist input / ouutput hysteresis phenomena, i A2ACPUP21-S4 Manual . e., the input / output response delay.
User program storage capacity: it is a measure of how much the user application can store the number of indicators.
