Abstract
Methods, apparatus, and systems are provided for a web browser accessible data file system on a programmable logic controller (PLC). The invention includes a PLC which includes a controller module; a file system module coupled to the controller module and adapted to persistently store archive data files; a memory module that stores binary data coupled to the controller module; and a user program module that stores instructions adapted to be executed by the controller module. The instructions may include creating an archive file in a user application format in the file system module; storing binary data in the memory module; converting the binary data to the user application format of the archive file; and storing the converted binary data as an entry in the archive file in the file system module. Numerous additional aspects are disclosed.
