    Default Memory_retain_param

    I'm thinking of adding the MEMORY_RETAIN_PARAM function block to an existing application for a few variables I want retained when program revisions are downloaded. The application already has a lot of retained variables declared. Will the MEMORY_RETAIN_PARAM function block have any effect on the existing retained variables; if so, what? Thanks.

    It won't have any affect on the current retains. All the MEMORY_RETAIN_PARAM does is allow you to assign the variables to a specific memory location, and to protect them.
