5.2.4 Input Relays (X)


Input function
The input is connected to the input device (external devices such as button switches, rotary switches, and
number switches), and PLC reads the input signal. You can use input contact A or contact B several times
in the program, and the ON/OFF input state varies with the ON/OFF input device state.

Input number (the decimal number):
For the PLC, the input numbers start from X0.0. The number of inputs varies with the number of inputs on
the digital input/output modules. The inputs are numbered according to the order in which the digital
input/output modules are connected to the CPU module. The maximum number of inputs for the PLC is
8192, and the input number range is between X0.0 and X511.15.

Input type: Inputs are classified into two types.
1. Regenerated inputs: PLC reads the state of a regenerated input before the program is executed. For
example, LD X0.0.
2. Direct input: The state of a direct input is read by the PLC during the execution of the instructions. For
example, LD DX0.0.
