Addressing

Flat Addressing

This module requires 64 contiguous, input references (%I) - 32 for input data and 32 for broken wire signal or 4 contiguous input words (%IW) 2 for input data and 2 for broken wire signal. The data word formats are as follows.

Input Words (Data):

Topological Addressing

Topological addresses in Bit Mapping format:

Point	I/O Object	Comment
Input 1	%I[\b.e\]r.m.1.1	Value
Input 2	%I[\b.e\]r.m.2.1	Value
• • •
Input 31	%I[\b.e\]r.m.31.1	Value
Input 32	%I[\b.e\]r.m.32.1	Value
Broken Wire 1	%I[\b.e\]r.m.1.2	Value
Broken Wire 2	%I[\b.e\]r.m..2.2	Value
• • •
Broken Wire 31	%I[\b.e\]r.m.31.2	Value
Broken Wire 32	%I[\b.e\]r.m.32.2	Value

Topological addresses in Word Mapping format:

Point	I/O Object	Comment
Inputword 1	%IW[\b.e\]r.m.1.1	Value
Inputword 2	%IW[\b.e\]r.m.1.2	Value
Inputword 3	%IW[\b.e\]r.m.1.3	Broken Wire Flag
Inputword 4	%IW[\b.e\]r.m.1.4	Broken Wire Flag

Used abbreviations: b = bus, e = equipment (drop), r = rack, m = module slot.

I/O Map Status Byte

The eight bits in the I/O map status byte are used as follows:
