Memory bits used to control inputs and output signals in PLC /Addressing in PLC/PLC Automation by Bestway
Memory bits used to control inputs and output signals in PLC In Micro controller based device memory is divided into three category i.e. Program, Discrete or Digital Registers and word. Data is held in these Registers. These Registers come in different sizes, and hold different kinds of data. Bits or Boolean : Can have values 1 or 0 Condition. 1 is represents On while 0 represents Off. Bits are the building block for all other types of data. These Boolean values are used for all the input and output devices like sensor and switch inputs, as well as motor or other outputs. Integers (Multiple Bits) : Multiple-bit integers are usually 8, 16, or 32 consecutive bits and can hold only whole number values. Whole numbers also Called as Characters (char), Integers (int), long Integers (long int) or Words. Depends on bit size and whether they are signed or unsigned. Unsigned Integers are positive numbers, while s...
