Points (bits) can be referenced using the optional Byte, Word, Short, DWord and Long data types. The following diagram illustrates how the driver maps bits within these data types.

 

 

All digital inputs and outputs can be addressed as Byte, Word, Short, DWord or Long data types. When addressing a module (such as an 8 bit input module) as a Word data type, the upper 8 bits will be fixed at zero while the lower bits will contain the status of the 8 inputs.
