Test & Simulation RTU500 series Remote Terminal UnitInputs and Outputs view - elements of the user interface4-8 | 1KGT 150 924 V000 1 - ABB AGFigure 49: Simulation interval and STOP button4.4.4 Control panel for process connectionIn the upper right corner of the user interface, the control panel for process connection can be found.Please notice that this element do not signalize any status, it just provides the option to proceed withdisconnection/reconnection of signals and to set the automatic simulation of command responsesand reactions.The actions carried out in this control panel have only effect on the signals which are displayed atthat moment in the grid, and not on the rest of hidden signals.In the control panel, the user can select to disconnect or reconnect signals, and in which direction(monitoring, controlling or both). See figure Fig. 50 and figure Fig. 51 depict this:Figure 50: Process connection - directionFigure 51: Process connection - valueWhen the appropriate direction and value are selected, the user must click on the "Proceed" buttonto apply the changes.Disconnecting signals in monitoring directionWhen a signal is disconnected from process in monitoring direction, the RTU500 will block thatobject's inputs, not sending them to the host system and not updating the RTU500 database withthe real value of the signal.In the following example (Fig. 52), a SPI signal which belongs to a sub-device has been disconnectedfrom process in monitoring direction. Updates in the SPI's real value are blocked and not sent to thehost systems. Instead, the user can simulate the signal by means of the Test Mode user interface.
