SI-200/250 fiber optic cable.
Double loop.
MELSECNET (II) (remote I/O station).
According to the control requirements of the system, using the appropriate design method to design MITSUBISHI PLC program.
Procedures to meet the requirements of system control as the main line,
Write one by one to achieve the control function or the sub task of the program,
GGradually improve the functions specified by the system A1S68DAV.
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 A1S68DAV.
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 A1S68DAV.. Input type: DC input, positive / negative public end.
Input points: 8 points.
Enter the response time: 1.5ms the following.
Rated input voltage / current: DC24V/7mA.
Output form: relay output.
Output points: 8 points MITSUBISHI A1S68DAV.
OFF leakage current: -.
Output protection function: No.
Rated load voltage / current: DC24V/AC240V/2A.
External connection: 3 line /2 line type.
According to the external connection mode and the external equipment input and output specifications,
Choose from a rich product lineup MITSUBISHI A1S68DAV.
Finger protection through the upper part of the terminal,
The human body will not be exposed to live parts,
Therefore, the terminal station type remote I/O module can be directly mounted to the machine tool.
8 channel analog output module.
Ans series has now launched a dedicated 8 channel D/A components,
Both voltage output and current output can be provided MITSUBISHI A1S68DAV.
In this way, the user system to provide a higher density of D/A features,
The same method is used to maintain the same output voltage or current output. Ontology CPU installation to P-ROM program device.Input points: 16 points.

36 point terminal station.
With the surge absorber.
Control solenoid valve required I/O points by the action principle of the solenoid valve can be known,
A single coil solenoid valve with PLC control to 2 input and 1 output,
A double coil solenoid valve requires 3 inputs and 2 outputs,
A button needs an input; a light sensitive switch needs 4 or 2 inputs,
A signal lamp needs 1 output, band switch,
Several bands are required for several inputs,
In general, a variety of position switches are required to take up 2 input points.
MITSUBISHI PLC is the main product in the production of MITSUBISHI motor in Dalian.
It uses a kind of programmable memory for its internal storage procedures,
Execute logic operation, sequence control, timing, counting and arithmetic operations, user oriented instruction,
And through digital or analog input / output control of various types of machinery or production process.
The number of I/O thyristor DC motor control required tube DC motor speed control system is the main form of DC speed regulation,
The thyristor rectifier unit is used to supply power to the DC motor.
PLC control of the DC drive system, the input of the PLC in addition to the main signal outside the signal,
We need to consider the switching signal, the fault signal transmission device, brake signal and fan fault signal.
The output of the PLC mainly consider the speed command signal positive 1~3 level, 1~3 level, allowwing reverse switching signal and brake open signal etc A1S68DAV..
In general, a reversible DC drive system controlled by PLC is approximately 12 input points and 8 output points,
An irreversible DC drive system requires 9 inputs and 6 output points.
