        Communicate with 1756 I/O

When you finish, the Tags window should look similar to the 
following:

Tag Name

Alias For

Base Tag

start

conveyor:1:I.Data.1(C)

conveyor:1:I.Data.1(C)

start

 is an alias for point 1 of the input module that is in slot 1 of a remote chassis (named 

conveyor).

TIP

Even if the I/O module uses the Rack Optimization Comm Format, 
address the required point as described in step F.

However, the ladder logic displays the address of the data within the 
CNB structure:

Tag Name

Base Tag

conveyor:I.Slot[1].Data.1(C)

start

 is an alias for point 1 of the input module that is 

in slot 1 of a remote chassis (named conveyor).

Because the module uses the Rack Optimization format, a structure 
associated with the CNB module actually transfers the data.
