SI/QSI/H-PCF/ wide range H-PCF fiber optic cable.
Double loop.
Remote I/O network (remote control station).
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 A73CPU Programming Manual A73CPU
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 A73CPU Programming Manual .

24 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 progrram 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 thee program A73CPU Manual A73CPU Manual.
Depending on the way the field signals are generated,
The simulation debugging has two forms of hardware simulation and software simulation.
