All signals from sensors connected to the cabinet of automated process control, which is located in the unit and is hinged. Signals of the automated process control cabinet are sent to normalization motherboard and galvanic isolation (our own production). Further analogue-to-digital conversion (PCL-818, Advantech) and discrete input boards(UNIO-95-5, Fastwel) are used, they are digitise. Obtained values are programmatically converted into real variables (PCA-6753, Advantech) and transmitted through information communication channels to PC, local operator terminal and digital indicators for displaying and archiving.
Software of process control automation system is based on SCADA/HMI system Trace Mode 5.
F or compatibility with Trace Mode 5 Built-in software of graphic operator terminal and digital indicators have been modified. Which resulted connection on the native for Trace Mode protocol M-Link (RS-485). Connectedness between automated process control cabinet Central control panel was implemented through the Ethernet channel.
Function funds control system distributed as follows:
In the process of working with PC, monitor displays the mnemonic technological process. The mnemonic schematically shows the equipment and placement of sensors. Switched on equipment is distinguished by backlight or image of movement.
During operation the system forms so-called report of alerts, which is recorded in form of various kind operational information messages:
