According to the control requirements of the system, using the appropriate design method to design MITSUBISHI PLC program.
Procedures to meet the requirements of system control as the main line,
Write one by one to achieve the control function or the sub task of the program,
Gradually improve the functions specified by the system A951GOT-QSBD-B Manual.
MITSUBISHI PLC initialization procedure. After MITSUBISHI PLC on power, the general need to do some of the initial operation,
In order to start making necessary preparations, to avoid the wrong operation of the system A951GOT-QSBD-B
The main contents of the initialization program are: to some data area, counter and so on,
Data needed to restore some of the data area,
Set or reset some relays,
For some initial state display, etc A951GOT-QSBD-B Manual. . "RS-422 1 channel.
Communication speed: 500kbps.
Connection points: 512 points (set switch) /3584 point (the upper controller).
How to determine the input / output device of MITSUBISHI plc.
According to the control requirements of the system,
All input devices and output devices required for the determination of the system,
To determine the input / output device related to the MITSUBISHI PLC,
To determine the I/O PLC points A951GOT-QSBD-B Manual.
Detailed analysis of the process and work characteristics of the controlled object,
To understand the coordination between the controlled object machine, electricity and liquid,
The control requirements of the controlled object for MITSUBISHI PLC control system are put forward,
Determine the control program, to develop a design task book MITSUBISHI A951GOT-QSBD-B User's Manual MITSUBISHI A951GOT-QSBD-B User's Manual. Output type: transistor source.
Output points: 16 points.
Load voltage: DC12/24.
Load current: 0.8A.
Connection mode: terminal row.
Common public end points: 8.
Switching value, also known as logic, refers to only two values, 0 or 1, ON or OFF.
It is the most common control, it is the advantage of PLC control,
Is also the most basic application of PLC MITSUBISHI A951GOT-QSBD-B User's Manual.
Switch volume control is designed to,
According to the current input combination oof the switch quantity and the history of the input sequence,
So that PLC generates the corresponding switching output,
In order to make the system work in a certain order A951GOT-QSBD-B Connection System Manual.
So, sometimes also known as the order control.
And seqquential control is divided into manual, semi-automatic or automatic A951GOT-QSBD-B Manual.
And the control principle is decentralized, centralized and hybrid control three.
