7.2 Formatting Explicit Messages for a
ControlLogix Controller
ControlLogix scanners accommodate both downloading Explicit
Message Requests and uploading Explicit Message Responses.
The scanner module can accommodate one request or response for
each transaction block. Each transaction block must be formatted
as shown in figure 7.1. Refer to table 7.1 for a description of the
data that is required in each box (items 1 – 9).
To display the Message Configuration dialog box in RSLogix 5000,
add a message instruction, create a tag for the message
(properties: base tag, MESSAGE data type, controller scope), and
click the blue box inside the message.
When using a 1756-DNB scanner, five Explicit Messages can be
executed at a time.
