Access Distributed I/O

I/O information is presented as a structure of multiple fields, which depend

on the specific features of the I/O module. The name of the structure is based

on the location of the I/O module in the system. Each I/O tag is

automatically created when you configure the I/O module through the

programming software. Each tag name follows this format:

Location:SlotNumber:Type.MemberName.SubMemberName.Bit where:

This address variable: Is:

Location Identifies network location

LOCAL = local DIN rail or chassis

ADAPTER_NAME = identifies remote adapter or bridge

SlotNumber Slot number of I/O module in its chassis

Type Type of data

I = input

O = output

C = configuration

S = status

MemberName Specific data from the I/O module; depends on the type of data the module can store

For example, Data and Fault are possible fields of data for an I/O module. Data is the common name for

values the are sent to or received from I/O points.

SubMemberName Specific data related to a MemberName.

Bit (optional) Specific point on the I/O module; depends on the size of the I/O module (0-31 for a 32-point module)
