This panel shows the values and the status (if e.g. alarms defined) of parameters read from PLC1, the current status of OPC server for PLC1 and the status of PLC1 in a hardware level (ref. 2.15). In reality much more than two channels could be read from the PLC1 therefore in the future the developers must modify this panel to show the status of all the possible items which can be read.
The two text fields for showing the value of Alarm and Pressure are references to a FW panel called `AIsummaryAct.pnl'. Background color of these elements changes according to defined color convention (ref. General Compass DCS document).
