MicroLogix 1500 Ladder Example Program
Explicit messaging (parameter read/write) capability varies between the
controllers and RSLogix software packages:
Controller Used With 1769-SM1
MicroLogix 1500 LSP Series A, B, and C
MicroLogix 1500 LRP Series A and B
MicroLogix 1500 LRP Series C
• RSLogix 500 (version 6.0 or lower) does not support creating a
Message instruction for the 1769-SM1. This limits the MicroLogix
1500 to performing I/O messaging (Logic Command/Reference,
Logic Status/Feedback, and Datalinks) only.
• RSLogix 500 (version 6.1 or higher) must be used to create Message
instructions for sending explicit messages to the 1769-SM1.

Note that the Data Out settings are set to match the respective Data In
settings for demonstration purposes only. This allows read/write
capability for the eight parameters selected and provides the ability to
verify that a change was made to a parameter value.
