Input and output points: 1024 points.
Input / output data points: 1024 points.
Program capacity: 14K.
Basic command processing speed (LD command) s:1.0.
Coaxial data communication line function.
User program storage capacity: it is a measure of how much the user application can store the number of indicators A2ACPUP21-S1 Manual A2ACPUP21-S1 User's Manual.
Usually in words or K words as units. 16 bit binary number is a word,
Every 1024 words are 1K words A2ACPUP21-S1 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 A2ACPUP21-S1 Manual A2ACPUP21-S1 User's Manual.
Modular: PLC is the basic components of a separate module.
Medium and large PLC used this way. Easy maintenance. 3C-2V/5C-2V coaxial cable.
Double loop.
PC inter network (management station / station) / remote I/O network (remote control station) A2ACPUP21-S1 Manual A2ACPUP21-S1 User's Manual.
How to choose MITSUBISHI PLC.
MITSUBISHI PLC options include the choice of MITSUBISHI PLC models, capacity, I/O module, power, etc..
MITSUBISHI PLC distribution I/O points and design MITSUBISHI PLC peripheral hardware circuit
Draw the I/O point of the PLC and the input / output device connection diagram or the corresponding table,
This part also can be carried out in second steps.
Design PLC peripheral hardware circuit.
Draw the electrical wiring diagram of the other parts of the system,
Including the main circuit and the control circuit does not enter the PLC, etc..
The electrical schematic diagram of the system composed of I/O PLC connection diagram and PLC peripheral electrical circuit diagram.
So far the system''s hardware electrical circuit has been determined. Multi axis positioning controller.
Coaxial data communication line function.
Program capacity: Max 60K step.
Input / output points: 1920 points.
PLC commonly used in memory are EPROM, EEPROM and with lithium battery powered RAM A2ACPUP21-S1 Manual A2ACPUP21-S1 User's Manual.
General micro and small PLC storage capacity is fixed, between 1~2KB.
How much memory is occupied by a user application is related to many factors,
Such aas I/O points, control requirements, computing processing, program structure, etc A2ACPUP21-S1 Manual A2ACPUP21-S1 User's Manual. .
So it can only be roughly estimated before the program is designed.
