Input and output points: 256 points.
Input / output data points: 256 points.
Program capacity: 6k.
Basic command processing speed (LD command) s:1.0.
Internal storage RAM memory capacity: 16k.
Optical data communication line function with power supply.
User program storage capacity: it is a measure of how much the user application can store the number of indicators.
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 logical operation instructions each account for 1 words. Timer / counter,
Shift instruction accounted for 2 words. Data operation instructions for 2~4.
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.
Modular: PLC is the basic components of a separate module.
Medium and large PLC used this way. Easy maintenance.

A1NCPUP21
50 point terminal station.
Control solenoid valve required I/O points by the action principle of the solenoid valve can be known,
A single coil solenoid valve with PLC control to 2 input and 1 output,
A double coil solenoid valve requires 3 inputs and 2 outputs,
A button needs an input; a light sensitive switch needs 4 or 2 inputs,
A signal lamp needs 1 output, band switch,
Several bands are required for several inputs,
In general, a variety of position switches are required to take up 2 input points MITSUBISHI A1NCPUP21.
MITSUBISHI PLC is the main product in the production of MITSUBISHI motor in Dalian.
It uses a kind of programmable memory for its internal storage procedures,
Execute logic operation, sequence control, timing, counting and arithmetic operations, user oriented instruction,
And through digital or analog input / output control of various types of machinery or production process MITSUBISHI A1NCPUP21.
The number of I/O thyristor DC motor control required tube DC motor speed control system is the main form of DC speed regulation,
The thyristor rectifier unit is used to supply power to the DC motor MITSUBISHI CPU unit.
PLC control of the DC drive system, the input of the PLC in addition to the main signal outside the signal,
We need to consider the switching signal, the fault signal transmission device, brake signal and fan fault signal MITSUBISHI CPU unit.
The output of the PLC mainly consider the speed command signal positive 1~3 level, 1~3 level, allowing reverse switching signal and brake open signal etc MITSUBISHI CPU unit. .
In general, a reversible DC drive system controlled by PLC is approximately 12 input points and 8 output points,
An irreversible DC drive system requires 9 inputs and 6 output points. Memory card interface, serial interface.
On-line debugging is the process that will through the simulation debugging to further carry on the on-linne unification to adjust A1NCPUP21.
On-line debugging process should be step by step,
From MITSUBISHI PLC only connected to the input device, and then connect the output device, and then connect to the actual load and so on and so on stepp by step MITSUBISHI A1NCPUP21.
If you do not meet the requirements, the hardware and procedures for adjustment.
Usually only need to modify the part of the program can be.
