MND decided to equip the existing control system with mySCADA Box 3G. A Ethernet/IP connection between the ControLogix PLC and mySCADA Box was established without need to shut the system down. It was necessary to log the data from 7 gas pressure convertors and 2 temperature sensors. Data were logged with 1-second precision with hysteresis detection. mySCADA Box was capable to log into its internal memory over 28 000 000 of analog values to achieve data history of more than 5 years of continuous system monitoring.
GSM 3G module of mySCADA Box allowed for secure connection from remote PC without need for additional infrastructure. Such connection made possible to monitor online actual and historical date from the controller. With the freely available reporting software myREPORTS this data could be displayed in graphic form and transferred into reports to perform advanced diagnostics.
