Abstract
A networking PLC core comprising a program for uniting a programmable logic controller function to a fourth transport layer and a fifth session layer in compliance with network communication specifications in an OSI reference network model embedded therein, and a single or plural ICs or modules for exclusive use which are configured to store, manage and execute the program.
Claims8
A networking core comprising:
- a single or plural ICs or modules for exclusive use in which a communication function based on a network having an OSI reference network model and a hierarchical protocol pursuant thereto are embedded, wherein
- the single or the plural ICs or modules for exclusive use comprise the fourth layer, or a transport layer, and the fifth layer, or a session layer, which are network communication procedure specifications in the OSI reference network model,
- a program for uniting commands, addresses, program system, run logic, and run system in a programmable logic controller function is embedded in the fourth layer, or the transport layer, and the fifth layer, or the session layer, and
- the single or the plural ICs or modules for exclusive use store and manage the program, and store and execute a user application program.
