What Is Meaning Of Resolution In I/o Cards In Plcs ? |
|
Answer» It is the minimum CHANGE in i/p parameter which can sensed by the i/p card. As far as Digital I/O is concerned it takes only ONE bit for operation. In case of analog input the resolution determines how much BITS are used for input or output. For example a 12 bit resolution card MEANS the input will come as 0 to 4095 count (2^12). For 16 bit data the counts will be from 0 – 65536(2^16). More the resolution the data will be more accurate It is the minimum change in i/p parameter which can sensed by the i/p card.
