OK, got it.

I'm not sure what Is the IoX device, but I have an ISY994 firmware version v.4.9.0. I am getting the gate status from a relay on the gate control board. (It was a long time ago). My 2450 I/O link provides the sensor status to the ISY. This is the code: End Gate Activity - [ID 0068][Parent 0023] If Status 'My Devices / My Sensors / Gate Open Sensor' is Off Then Run Program 'Text: End Gate then' (Then Path) Run Program 'Gate Closed Car Activity ' (If) Else Run Program 'Text: End Gate Else' (Then Path) Run Program 'Gate Closed Reset Switches' (Then Path)

I have a problem with a program that leaves me to believe that I am missing Info about how UD handles changes in sensor status. The If statement in my program which is not called by any other program "If gate open sensor is off" relies solely on the change in gate status to run. It is the only program that tests the sensor being off. I don't know how but it executes the Else statement. How can this be? I would like to know how ISY triggers this program to run.
