The user manually actuates a device.
The user puts an instrumentation division in or takes a division out of 'maintenance' mode.
The user adjusts the setpoint for a particular channel in a particular division in maintenance mode.
The user sets the mode of the channel of an instrumentation division to either bypass or normal mode.
The user sets the mode of the channel of an instrumentation division to either trip or normal mode.
The UI displays the current pressure reading for an instrumentation division.
The UI displays the current temperature reading for an instrumentation division.
The UI displays the current saturation margin reading for an instrumentation division.
The UI displays the current trip signal output for a particular channel and instrumentation division.
The UI displays the current bypass mode for a particular channel and instrumentation division.
An instrumentation division reads a pressure sensor value that exceeds its setpoint and generates a trip output.
An instrumentation division reads a temperature sensor value that exceeds its setpoint and generates a trip output.
An instrumentation division reads temperature and pressure values such that the saturation margin is below its setpoint and generates a trip output.
An actuation unit reads two like trip inputs and generates the corresponding automatic actuation signal.
An actuation unit generates an automatic actuation signal and sends it to the corresponding device.
The RTS simulates inputs to a pair of instrumentation divisions and checks the corresponding actuation signals.
