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.
Claims19
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, prior to reading a data log file on the memory cartridge connected to the PLC, a user with an option to automatically erase the data log file from the memory cartridge after reading the data log file;
- receiving a user input corresponding to a selection related to erasure of the data log file from the memory cartridge after reading the data log file;
- and
- reading the data log file.
A method comprising:
- subsequent to a received user input regarding an option to automatically erase a data log file from a memory cartridge after reading the data log file and responsive to a data log structure of the data log file, automatically reading a data log file from a memory cartridge connected to a programmable logic controller, the memory cartridge comprising a plurality of memory segments, the user input received responsive to a prompt, the data log structure stored separately on the memory cartridge from the data log file.
A memory comprising computer-executable instructions for activities comprising:
- responsive to a received user input of an option to erase a read data log file and responsive to a structure of the data log file, automatically erasing the data log file from a memory cartridge connected to a programmable logic controller after reading the data log file, the memory cartridge comprising a plurality of memory segments, the user input received responsive to a prompt, the structure of the data log file stored separately from the data log file in the memory cartridge.
