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 A3NCPUP21 Dedicated Instructions Manual A3NCPUP21 Programming Manual.
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 into digital signals,
The analog output unnit (D/A), in order to transform the digital quantity after PLC processing into analog quantity -- standard electric signal A3NCPUP21 Dedicated Instructions Manual A3NCPUP21 Programming Manual.
So the standard telecommunication number, the conversiion between the number of operations to use a variety of computing A3NCPUP21 Dedicated Instructions Manual A3NCPUP21 Programming Manual.
This requires the resolution of the analog unit and the standard electrical signal.
