In case of a digital I/O module, the channels are provided as WORD, BYTE and BOOL. Because the analog inputs can also be configured as digital inputs, bit 0 of each channel is also available as BOOL.
The symbolic name of a channel can be entered in front of the string “AT” in the channel declaration.
All channels should have a symbolic name and only symbolic names should be used in the program code. If the hardware configuration changes or if the project is downloaded to a PLC with a different hardware configuration, the addresses of inputs and outputs can change. When symbolic programming is used (i.e., symbolic names are used), the program code does not need to be changed.
