Modification to DIGITAL INPUT STATUS

Proposed modification to DIGITAL_INPUT_STATUS.

Add Byte 4, Bits 0 to 3, Bank Select
Range: 0 - 13, 0xF – Banking not supported in this installation

The Bank Select is identical to the Bank Select in the Generic Indicator. This increases the number of Digital Inputs supported on a network to 3500, and makes it easier for designers to prevent overlap between instances.
