Abstract
A programmable logic controller (PLC) system is provided. The programmable logic controller (PLC) system divides a memory region into a plurality of regions according to a function, and reads or transmits data from or to the divided regions according to an operation mode to be performed, wherein the plurality of regions obtained through division includes: a first storage region storing log data on the PLC system; and a second storage region storing a hyper text markup language (HTML) file.
Claims5
A programmable logic controller (PLC) system connected to a memory card, wherein the PLC system comprises:
- a data log module, which when executed by a microprocessor in the PLC system, executes a data log function execution mode;
- a web server module, which when executed by the microprocessor, executes a web server function execution mode;
- and
- a file system, which when executed by the microprocessor, controls the memory card to be divided into a plurality of regions corresponding to a plurality of functions, respectively, when the file system is initialized,
- wherein the plurality of regions obtained through the division comprises:
- a first storage region storing log data of the PLC system;
- and
- a second storage region storing a hyper text markup language (HTML) file, wherein the file system is configured to:
- transmit the log data to store the log data into the first storage region of the memory card when the data log function execution mode is sensed, and
- read the HTML file from the second storage region of the memory card when the web server function execution mode is sensed.
An operating method of a PLC system connected to a memory card, the operating method comprising:
- dividing, by a microprocessor in the PLC system, the memory card into a first storage region and a second storage region, the first storage region storing log data of the PLC system, and the second storage region storing a hypertext markup language (HTML) file when the file system is initialized;
- sensing, by the microprocessor, if a data log function execution mode is executed by a data log module or a web server function execution mode is executed by a web server module;
- transmitting, by the microprocessor, the log data to store the log data into the first storage region of the memory card when the data log function execution mode is sensed;
- and
- reading, by the microprocessor, the HTML file from second storage region of the memory card when the web server function execution mode is sensed.
