Abstract

The present invention provides a programmable display, and relates to a configuration for appropriately securing a security level for the displayed content in a programmable display capable of remotely observing the displayed content. The programmable display connected to the control device has: a user management unit, which is used to identify a user who accesses the programmable display; a generation unit, which generates a user from the an interface screen of information of the control device; a display section which outputs the interface screen; and a connection management unit which, in response to an access request from a user of the external device, establishes a connection with the external device based on an identification result of the user obtained by the user management unit. connection, and send the interface screen to the external device that has established the connection; the user management unit prevents multiple users who are each given different rights from accessing the programmable display at the same time.

Description

technical field [0001] The present invention relates to a programmable display for browsing or operating a control system including a control device. Background technique [0002] In a general manufacturing site, a control device called a PLC (Programmable Logic Controller; Programmable Logic Controller) is used to control manufacturing devices, robots, and the like. With the demand for labor saving in the manufacturing site and the progress of ICT (Information and Communication Technology; information communication technology), etc., technologies for remote viewing or operation using network technology have been developed. [0003] For example, JP Unexamined Patent Publication No. 2008-33573 (Patent Document 1) discloses a configuration in which a screen displayed on a programmable display can be remotely displayed, and operations similar to those of the programmable display can be performed on the displayed screen. . More specifically, the programmable display of patent ...
