Connection Tab

2. Reset the module via the modules properties dialog. Module Info tab.

3. Reset the module via ladder logic. See the “DoReset” rung in the

sample ladder located in Chapter 8.

4. Perform a “Set Attribute All” or Module Reconfigure message

instruction via ladder logic. Refer to Chapter 8 for information about the

“DoSetAttrAll” command.

Note: If an invalid configuration is sent to the module a connection error

will occur. See chapter 9 for a list of error codes.
