Also refer to the EXRAIL Sensor commands:

• JMRI_SENSOR(vpin [,count]) - Creates <S> type sensors visible to JMRI
• AT( vpin ) - Causes a sequence to wait until a sensor is active/triggered
• AFTER( vpin ) - Causes a sequence to wait until after a sensor has been triggered
• ATTIMEOUT( vpin, timeout_ms ) - Causes a sequence to wait until either a sensor is active/triggered, or if the timer runs out
• IF( vpin ) - If sensor activated or latched, continue
• IFNOT( vpin ) - If sensor NOT activated and NOT latched, continue
• IFTIMEOUT - Tests if “timed out” flag has been set by an ATTIMEOUT() sensor reading attempt
• ATGTE( vpin, value ) - Waits for an analog pin to reach a value
• ATLT ( vpin, value ) - Waits for an analog pin to go below a value
• IFGTE( vpin, value ) - Test if analog pin reading is greater than or equal to value
• IFLT( vpin, value ) - Test if analog pin reading is less than value
• ATTIMOUT1 ( vpin, value ) - TBA
• ATTIMOUT2 ( vpin, value ) - TBA
• DRIVE ( vpin ) - TBA
• LATCH( vpin ) - Latches a sensor on
• UNLATCH( vpin ) - Remove LATCH on sensor
• ONBUTTON( vpin ) - Event handler for debounced button presses
