Addressing

Flat Addressing

This module requires nine contiguous, 16-bit words—eight for input data and one for channel status. The data words formats are as follows.

The following shows the word 9 register.

*A range warning is issued when a channel input exceeds the rated input value. Warning bit stay on after out of range bits are set.

**An out-of-range bit is set when a channel input exceeds the rated input value by 2.4% or when a broken wire (4 ... 20 mA or 1 ... 5 V mode) is sensed on the channel. Out of range bits are also set if inputs drop below 0.5 V (1 ... 5 V mode) or 2.08 mA (4 ...20 mA mode).

Topological Addressing

Topological addresses for the 140 AVI 030 00 Input Module:

Point	I/O Object	Comment
Input 1	%IW[\b.e\]r.m.1	Value
	%I[\b.e\]r.m.1.1	Out of range
	%I[\b.e\]r.m.1.2	Range warning
• • •
Input 8	%IW[\b.e\]r.m.8	Value
	%I[\b.e\]r.m.8.1	Out of range
	%I[\b.e\]r.m.8.2	Range warning
Status Word	%IW[\b.e\]r.m.9	Status of input channels

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

IODDT

The 140AVI03000 Input Module uses the T_ANA_IN_VWE IODDT:

IODDT Name	Object		Data Type		Name
T_ANA_IN_VWE	%CH[\b.e\]r.m.c		ANA_IN_VWE		userdefined
		%IWr.m.c.0		Int		.VALUE
		%Ir.m.c.1		Bool		.ERROR
		%Ir.m.c.2		Bool		.WARNING

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

Bus and Drop default to 1 if not specified and can be left off.

NOTE: In Quantum IODDTs for analog modules and expert modules the data type Bool is used for %I and %Q.

I/O Map Status Byte

The I/O map status byte is used by the 140 AVI 030 00 Input Module as follows.
