For more information on configuration, see 1734/1738 I/O Module
Assembly Information.
After the configuration has been entered into the tag, remember to
save the RSLogix 5000 project. The tags are only retained upon a save. Also
remember that any configuration added here must be reflected in the
Configuration Size of the Connection Parameters entered on the Module
Properties dialog.
If any part of the configuration assembly is wrong (either the minimal
assembly or a portion directed to an I/O module), the connection request will
be rejected with the General Return Code indicating an Error in the Data
Segment (0x09). The Extended Error code will indicate the byte offset into the
configuration data segment where the error was detected.
