MELSECNET/MINI (-S3) data link system, A2C system transfer converter.
Twisted pair cable - plastic optical fiber cable.
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 A1NCPUR21.
MITSUBISHI PLC initialiization 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 A1NCPUR21.
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 A1NCPUR21.
Depending on the way the field signals are generated,
The simulation debugging has two forms of hardware simulation and software simulation MITSUBISHI A1NCPUR21. Screw terminal table type.
High precision / high resolution / high speed 2 piece type terminal.
Voltage / current input module.
Number of channels: 4 channels.
Number of stations: 1 stops MITSUBISHI A1NCPUR21.
Station type: remote equipment station.
MITSUBISHI PLC hardware implementation
Hardware implementation is mainly for the control cabinet and other hardware design and field construction.
Design control cabinet and the operating table and other parts of the electrical wiring diagram and wiring diagram MITSUBISHI A1NCPUR21.
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 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.
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 and output points: 256 points.
Input / output data points: 256 points.
Program capacity: 6k.
Basic command processing speed (LD command) s:1.0.
Internal storage RAM memory capacity: 16k.
Optical data communication line function with power supply.
Input / output data control mode conversion.
It is possible to enter the control of the output data as the following 3.
(1) input: direct mode, output: direct mode.
(2) input: I/O impression update mode, output: direct mode.
(3) input: I/O impression update mode, output: I/O impression update mode.
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. 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 iinstalled in the casing to form a single overall called the host or the basic unit, small, ultra small PLC using this structure A1NCPUR21.
Modular: PLC is the basic components of a separate module.
Medium and large PLC used this way. Easy maintenance.
