A SUPERVISORY SYSTEM FOR MONITORING VARIABLES OF A PROCESS PLANT, characterized by comprising an interaction of an industrial automation configuration software with a spreadsheet program, where data is acquired instantly in the spreadsheet program from the industrial automation configuration software, and the acquired data is displayed on only two visualization screens within a same window, wherein
the system interacts with the spreadsheet program and the industrial automation configuration software for obtaining data instantaneously as follows: with the industrial automation configuration software and the spreadsheet program open, to establish a connection, insert a code into a cell of the spreadsheet program for returning only a value of the monitored variable that is linked to a server,
the code corresponds to a name of an executable in the industrial automation configuration software, a name of a tag library in the industrial automation configuration software, a registered name in the industrial automation configuration software to access the server, and a name of a tag registered in the industrial automation configuration software, and
additionally, a color change of one of parameters of the acquired data draws the attention of an operator, who has time to take an action before there is an occurrence or automatic actuation of an interlocking and control system.
