Ethernet I/O Data
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
This address variable Is
Location Identifies network location
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)
