Data register
When a PLC is used to perform various types of sequence control and set time
value and count value control, it most commonly perform data processing and
numerical operations, and data registers are used exclusively for storage of data
and various parameters. Each data register contains 16 bits of binary data, which
means that it can store one word. Two data registers with adjacent numbers can
be used to process double words.
