How to choose MITSUBISHI PLC.
MITSUBISHI PLC options include the choice of MITSUBISHI PLC models, capacity, I/O module, power, etc..
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 A9GT-FNB4M Hardware Manual A9GT-FNB4M User's Manual A9GT-FNB4M
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..
The electrical schematic diagram of the system composed of I/O PLC connection diagram and PLC peripheral electrical circuit diagram A9GT-FNB4M Hardware Manual A9GT-FNB4M User's Manual.
So far the system''s hardware electrical circuit has been determined. Input type: DC input, positive common end.
Input points: 16 points.
Enter the response time: 1.5ms the following.
Rated input voltage / current: DC24V/5mA.
External connection: 3 wire.
Spring clip terminal.
Do not need to be tightened further or locked with screws, which can reduce the working hours of wiring A9GT-FNB4M Hardware Manual A9GT-FNB4M User's Manual.
Using 2 pieces of structure of the terminal units, maintenance can be maintained in the same line under the condition of the replacement module.
When installing the module can choose to use the DIN guide rail or screw mounting.
Can be used for the 3 wire sensor input wiring. Transmission line unit for MELSECNET/MINI (-S3) twisted pair data link.
Loop: twisted pair I/F.
Remote station: twisted pair line I/F.
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 simulation debugging
The basic ideaa 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 A9GT-FNB4M Hardware Manual A9GT-FNB4M User's Manual A9GT-FNB4M Hardware Manual A9GT-FNB4M User's Manual.
Depending on the way the field signals are generated,
The simulation debugging has two forms of hardware simulation and software simulation.
