Address I/O Data

I/O information is presented as a set of tags.

• Each tag uses a structure of data. The structure depends on the

specific features of the I/O module.

• The name of the tags is based on the location of the I/O module

in the system.

An I/O address follows this format:

Location :Slot :Type .Member .SubMember .Bit

= Optional

Where: Is:

Location Network location

LOCAL = same chassis or DIN rail as the controller

ADAPTER_NAME = identifies remote communication adapter or bridge module

Slot Slot number of I/O module in its chassis or DIN rail

Type Type of data

I = input

O = output

C = configuration

S = status

Member Specific data from the I/O module; depends on what type of data the module can store.

• For a digital module, a Data member usually stores the input or output bit values.

• For an analog module, a Channel member (CH#) usually stores the data for a channel.

SubMember Specific data related to a Member.

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