Abstract
Certain exemplary embodiments can provide a method for utilizing a memory cartridge connected to a Programmable Logic Controller (PLC). The memory cartridge can comprise a plurality of memory segments. The method can comprise a plurality of activities comprising: providing a default identifying stamp for records in a data log file, a structure for the data log file stored separately from the data log file in the memory cartridge, and obtaining a request to provide the data log file.
Claims17
A method for utilizing a memory cartridge connected to a Programmable Logic Controller (PLC), the memory cartridge comprising a plurality of memory segments, the method comprising a plurality of activities comprising:
- providing a default identifying stamp for records in a data log file, a structure for the data log file stored separately from the data log file in the memory cartridge, a first head marker of the data log file indicative of a beginning memory segment for a data log record of the memory cartridge, the PLC changing the head marker on the memory cartridge to a record marker reflective of a data log record written in at least the beginning memory segment;
- and
- obtaining a request to provide the data log file.
A method for utilizing a memory cartridge connected to a Programmable Logic Controller (PLC), the memory cartridge comprising a plurality of memory segments, the method comprising a plurality of activities comprising:
- prompting a user to select an identifying stamp for records in a data log file, the data log file having a structure stored separately from the data log file in the memory cartridge, a first head marker of the data log file indicative of a beginning memory segment for a data log record of the memory cartridge, the PLC changing the head marker on the memory cartridge to a record marker reflective of a data log record written in at least the beginning memory segment;
- and
- receiving a user input corresponding to a selected identifying stamp for records in the data log file.
A System for utilizing a memory cartridge connected to a Programmable Logic Controller (PLC), the memory comprising a plurality of memory segments, the system comprising:
- means for providing a default identifying stamp for records in a data log file, a structure for the data log file stored separately from the date log file in the memory cartridge, a first head marker of the data log file indicative of a beginning memory segment for a data log record of the memory cartridge, the PLC changing the head marker on the memory cartridge to a record marker reflective of a data log record written in at least the beginning memory segment, the PLC receiving an input value corresponding to a process variable from a recipe stored on the memory cartridge, a structure of the recipe stored separately from the recipe, the input value usable by a program of the PLC to render a product associated with the PLC makeable;
- and
- means for obtaining a request to provide the data log file.
A non-transitory computer-readable storage medium containing instructions for activities for utilizing a memory cartridge connected to a Programmable Logic Controller (PLC) the memory cartridge comprising a plurality of memory segments, the non-transitory computer-readable storage medium comprising a plurality of activities comprising:
- providing a default identifying stamp for records in a data log file, a structure for the data log file stored separately from the data log file in the memory cartridge, a first head marker of the data log file indicative of a beginning memory segment for a data log record of the memory cartridge, the PLC changing the head marker on the memory cartridge to a record marker reflective of a data log record written in at least the beginning memory segment;
- and
- obtaining a request to provide the data log file.
