18 Using an Assembly Connection
Enter the Connection Parameters
In the New Module Properties dialog, enter Connection Parameters, the
Comm Format, the module's IP Address, and a name.
Enter a Name for the module that RSLogix 5000 uses in the tags that are
created for this module. The Data - SINT Comm Format should be selected,
indicating that all sizes are to be interpreted as a number of bytes. If this
connection is a Listen only connection, select the Input Data - SINT Comm
Format since it is otherwise not possible to enter an Output config assembly
size of 0.
Next, enter the Assembly Instances for the desired connection as
described in Connection Points. Enter the sizes (in bytes) for the Input and
Output instances per your calculations. See Calculate the Connection Size for
details on obtaining the sizes. If the optional status header is being used, its
size (8 bytes) must be included in the Input Size. For RSLogix 5000 the Output
Size does not include the Run/Idle header. Here the terms Input and Output
refer to the adapter's Produced and Consumed data respectively.
It is possible to make the connection without sending any
configuration data. The adapter's Chassis Size can be set from its web
page and the adapter will align produced and consumed data by
default on byte boundaries. If these options and the default configuration of all
I/O modules are acceptable, a 0 can be entered for the Configuration Size on
the Module Properties dialog. The configuration Assembly Instance must be
entered even if the size is 0. The following section will describe the steps taken
when configuration is needed.
Build the Configuration Tag
If any configuration is required, the minimum configuration header must be
sent and then any individual module configuration may follow. Open the
