Each equipment item can be assigned equipment actions to be executed at an event trigger. Equipment actions point to commands defined for each device interface loaded in the Events2HVAC application. For this reason, depending upon the interface selected for an equipment action, the available actions will vary. For example, a BACnet device might have a WriteProperty action to command a device to a particular value; but a P2000 device will not have a WriteProperty action because it doesn’t apply to security software.
