web-based multi PLC remote controlling system

摘要

The present invention relates to a web-based multiprocessor (PLC) remote control system, and more particularly, to a system in which a user can remotely control a plurality of PLCs using a web browser. To this end, the present invention provides a Pell City remote control system, comprising: a client connected to the Internet network for inputting and transmitting a work to be performed by the Pell City remote control system; A client manager for determining whether the command transmitted from the client is correct, transmitting the command to the outside, and transmitting the result to the client; A PELIX manager which receives commands from the client manager and transmits the commands to the outside, and periodically receives information on external conditions; And a central server for authorizing connection of the client, providing information on the remote control job on a web-based basis, and transmitting a job according to a request of the client to the PDSN manager. Accordingly, a user performing the above-described operation can control a specific machine connected to the PELSY using a general computer connected to the Internet through the Web, and can grasp the status of the operation of the machine remotely . In addition, since the number of administrators of the machines connected to Pielsi and Pielsi can be greatly reduced, there is an advantage that the cost of maintaining the manager can be drastically reduced.
