MITSUBISHI A2NCPU-S1 Programming Manual (Dedicated Instructions) PDF
Product model: A2NCPU-S1
Name: PLC
Brand: MITSUBISHI
Sort: Dedicated Instructions Programming Manual
File language: English
QnA/ACPU bus connection.
1 joint.
Applicable models: A985 (-V) /975/970/960/956 (W) GOT. Cable 0.6m for the expansion of the floor, the expansion of a floor for every 1 units A2NCPU-S1 PDF. Interface: RS422/485
Transmission distance: 500 meters
A1SJ71UC24-R2/R4/PR computer communication components can be relied on external intelligent devices such as computers and PLC for communication, the components are as follows:
Full / half duplex transmission,
4 special communication protocols,
No protocol and bidirectional mode,
Protocol selection switch function,
The optional baud rate, the highest 19 A2NCPU-S12K,
Since the echo diagnostic test,Input and output points: 4096 points A2NCPU-S1 PDF.
Input / output data points: 8192 points.
Program capacity: 30K.
Basic command processing speed (LD command) s:0.15.
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, small, ultra small PLC using this structure A2NCPU-S1 PDF A2NCPU-S1 Manual .
Modular: PLC is the basic components of a separate module.
Medium and large PLC used this way. Easy maintenance.
Each scanning process. Focus on the input signal sampling MITSUBISHI Programming 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 MITSUBISHI Programming Manual.
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 MITSUBISHI Programming Manual.
Centralized output mode.
There exist input / output hysteresis phenomena, i.e., the input / output response delay.
User program storage capacity: it is a meeasure of how much the user application can store the number of indicators A2NCPU-S1 Programming 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 A2NCPU-S1 Manual . Timer / counter,
Shift instruction accounted for 2 words. Data operation instructions for 2~4.
