I/O information is presented as a structure of multiple fields that 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 in RSLogix 5000 software. Each
tag name follows this format:

where:
Is
Identifies network location
LOCAL = local DIN rail or chassis
ADAPTER_NAME = identifies remote adapter or bridge that you specify
Slot number of I/O module location in its chassis
