Addressing

Flat Addressing

This module requires nine contiguous, 16-bit words—eight for input data and one for channel status. The data word 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. An out-of-range bit is set when a channel input exceeds the rated input value by 2.34% or when a broken wire is sensed on the channel. The warning bit is cleared (if set) when the out-of-range bit is set.

Topological Addressing

Topological addresses for the 140 ARI 030 10 Input Module:

Point	I/O Object	Comment
Input 1	%IW[\b.e\]r.m.1	Value
	%I[\b.e\]r.m.1.1	Broken wire or 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	Broken wire or 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 140 ARI 030 10 Input Module uses the T_ANA_IN_VE IODDT:

IODDT Name	Object		Data Type		Name
T_ANA_IN_VE	%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 ARI 030 10 Input Module as follows.
