The following example utilizes the input and output assemblies of 50 and 2.
The tables below list the data configuration for the ControlLogix platform and
include the Tag Name as used in the example program.

Table 56 - Example ControlLogix Output Address (consumed assembly)
The explicit message Request and Response is configured within the MSG
function. The MSG function can be found in the Input/Output tab of RSLogix
5000. Note that in the ControlLogix program example, rung 6 is the only
required logic to complete the explicit message request.
Table 57 - MSG Function Illustration
Setting Up the MSG instruction
A tag name must be given to the MSG function before the rest of the information
can be defined. In this example a tag was created with the name explicit_mess.
After the instruction has been named, click on the gray box to define the rest of
the instruction.
See Figure 58 as an example that shows the exact data format to perform a Get
Attribute Single request. This message specifically accesses parameter 104, Phase
