Description

The Input Bit register returns the state of the input bits referenced by the parameter. A non-zero value represents a high voltage and a 0 represents a low voltage. Note that this performs a direct read of the input bit and does not include setup configured properties that apply to a named resource that might be referencing the input bit such as bit inversion.

Escapes

A Parameter Out Of Range Escape Code will be generated if the parameter references an input beyond the range of the controller.

Examples

Query input 5 setting.

if Read_Word(System_+_InputBit5) <> 0 then
 Show_Message('Input 5 is high')
