16 channels.
Input: DC-10 ~ 10V, DC-20 ~ 20mA.
38 point terminal station.
Analog quantity I/P multiplexing unit (isolation channel).
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 A2CCPU Hardware Manual A2CCPU User's Manual A2CCPU
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 A2CCPU Hardware Manual A2CCPU User's Manual. DC input points: 16 points.
Input voltage and current: 7mA, DC24V.
Response time: 10ms.
16 point /1 a public side.
Positive / negative sharing.
40 point terminal station.
MITSUBISHI PLC protection and chain procedures.
Protection and chain is an indispensable part of the program, must be carefully considered.
It can avoid the control logic confusion caused by illegal operations A2CCPU Hardware Manual A2CCPU User's 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.
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..
MITSUBISHI PLC program simulation debugging
The basic idea of program simulation debugging is,
In order to facilitate the form of simulation to generate the actual state of the scene,
Create the necessary environmental conditions for the operation of the program.
Depending on the way the field signals are generated,
The simulation debugging has two forms of hardware simulation and software simulation. Output type: transistor drain.
Output points: 16 points.
Load voltage: DC24.
Load current: 2A.
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.
Switch volume control is designed to,
According to the current input combination of the switch quantity aand 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 A2CCPU Hardware Manual A2CCPU User's Manual.
So, sometimes also known as the order control.
And seqquential control is divided into manual, semi-automatic or automatic A2CCPU Hardware Manual A2CCPU User's Manual.
And the control principle is decentralized, centralized and hybrid control three.
