Cable length: 0.33 meters.
Extending cable to connect CPU main substrate and extended substrate,
According to the model can provide different cable length,
If you need to connect the AnN type expansion substrate is required,
Selection of A1SC05NB (A1SC07NB) cable. Transmission line unit for MELSECNET/MINI (-S3) twisted pair data link AY71 Manual AY71 User's Manual.

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 AY71 Manual AY71 User's Manual.
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 AY71 Manual AY71 User's Manual.
Depending on the way the field signals are generated,
The simulation debugging has two forms of hardware simulation and software simulation. Cable length: 30 meters.

PLC is introduced by the relay control technology after the development of micro processing technology,
Can be easily and reliably used for switching control.
As the analog quantity can be converted into digital quantity, the number of digital quantity is just a number of switching value,
Therefore, after the conversion of analog, PLC can also be reliable for processing control.
Because the continuous production process often has the analog quantity, the analog quantity control is sometimes called process control.
Analog quantity is not electricity, and PLC can only handle digital quantity, quantity of electricity.
All to realize the conversion between them to have the sensor, the analog quantity into a number of power.
If this power is not standard, but also through the transmitter,
The non-standard power into a standard electrical signal, such as 1-5V, 4-20mA, 0-10V, etc..
At the same time, there is also an analog input unit (A/D),
Transform these standard electrical signals intoo digital signals,
The analog output unit (D/A), in order to transform the digital quantity after PLC processing into analog quantity -- standard electric signal AY71 Manual AY71 User's Manual.
So the standard telecommunication number, the conversiion between the number of operations to use a variety of computing AY71 Manual AY71 User's Manual.
This requires the resolution of the analog unit and the standard electrical signal.
