Abstract
A system for configuring a controller without a file transfer. Programmable controllers may typically use configuration data structures that are transferred to the controller via a file transfer mechanism. The present controller does not necessarily need a tool with file transfer capability, but only a capability to read and write network variables. Configuration data structures may incorporate replacement specifications, and replacement constants representing replacement data to be selected. Changes of value in public variables may be identified as being replacement variables by virtue of their presence in the replacement specifications. When such changes of values are detected, instructions in the replacement specifications may detail how to modify the configuration file content associated with those public variables.
