RS-232:1, RS-422/485:1.
Transmission speed: 0.3 ~ 19.2kpbs.
Computer connection function.
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 A975GOT-TBD PDF. .
The electrical schematic diagram of the system composed of I/O PLC connection diagram and PLC peripheral electrical circuit diagram A975GOT-TBD
So far the system''s hardware electrical circuit has been determined.
Printer / peripheral device connection, BASIC language function.
How to choose MITSUBISHI PLC.
MITSUBISHI PLC options include the choiice of MITSUBISHI PLC models, capacity, I/O module, power, etc A975GOT-TBD PDF A975GOT-TBD Manual. .
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 A975GOT-TBD PDF. 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.
AnNCPU command processing time and ACPU compare to 10-20% high speed processing MITSUBISHI User's Manual.
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 MITSUBISHI User's Manual. Timer / counter,
Shift instruction accounted for 2 words. Data operation instructions for 2~4.
Integral type: the PLCC 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 thiss structure MITSUBISHI User's Manual A975GOT-TBD Manual A975GOT-TBD User's Manual.
Modular: PLC is the basic components of a separate module.
Medium and large PLC used this way. Easy maintenance.
