Screw terminal table type.
Voltage / current input module.
Number of channels: 4 channels.

MITSUBISHI PLC hardware implementation
Hardware implementation is mainly for the control cabinet and other hardware design and field construction MITSUBISHI A2UCPU PDF datasheet.
Design control cabinet and the operating table and other parts of the electrical wiring diagram and wiring diagram
A2UCPU
Electrical interconnection diagram of each part of the design system.
According to the construction drawings of the site wiring, and carry out a detailed inspection.
Because the program design and hardware implementation can be carried out at the same time,
So the design cycle of the MITSUBISHI PLC control system can be greatly reduced MITSUBISHI A2UCPU PDF datasheet.
MITSUBISHI PLC online debugging.
On-line debugging is the process that will through the simulation debugging to further carry on the on-line unification to adjust.
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 step by step MITSUBISHI A2UCPU PDF datasheet.
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. Input voltage range: DC110V.
Output voltage: DC5V.
Output current: 8A.
I/O points is an important indicator of PLC.
Reasonable selection of I/O points can not only satisfy the control requirements of the system,
And the total investment of the system is the lowest.
The input and output points and types of PLC should be determined according to the analog quantity and switch quantity of the controlled object,
Generally an input / output element to take up an input / output point.
Taking into account the future adjustment and expansion,
In general should be estimated on the total number of points plus the amount of spare 20%~30%.
The following describes the centralized control system I/O points of the estimate. Liquid crystal display: 16 characters x 2 lines,
For data access (the state of operation of the central processor, device monitor / change). DC input points: 2 points.
Input voltage and current: 7mA, DC24V.
Input response time: 10ms.
2 point /1 a public side.
Positive pole sharing.
Output points: 2 points.
Output voltage and current: DC24V.
Output response time: 2ms.
2 point /1 a public side.
Output form: transistor output, leakage type.
16 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.
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 siimulation 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 thee program A2UCPU PDF catalog A2UCPU PDF catalog.
Depending on the way the field signals are generated,
The simulation debugging has two forms of hardware simulation and software simulation.
