Calculation

Input Word Offset for slot x = # Input Words in slot 0 through slot (x-1).

Note 1: The Embedded I/O needs to be taken into account when offsetting to Expansion I/O.

Note 2: The number of Output words does not factor into the calculation for Input Word Offset.

I/O Example

Let

Slot 0 = MicroLogix 1500 LRP Series C = 4 Input Words

Slot 1 = 1769-OF2 = 2 Input Words

Slot 2 = 1769-OW8 = 0 Input Word

Slot 3 = 1769-IA16 = 1 Input Word

Slot 4 = 1769-OF8V = 11 Input Word

Bit 5 of Slot 3 = 4 + 2 = 6 words = I:6/5
