If you link two devices, for example LON1 and LON2, the LON2 device does not receive updates per Max Write Time. However, when the LON1 value changes, updates go out. The updated value does not depend on Max Write Time of LON2 device. These devices are linked between each other but not through proxy points.
Max Write Time is observed when the devices are linked through proxy points.
The MAX Write Time is one minute, which is sufficient enough to update before the received heartbeat expires.
