Return ValueThe value for this switch, this is expected to be between MinSwitchValue(Int16) and MaxSwitchValue(Int16).
Must be implemented, must not throw a.
Some devices do not support reading their state although they do allow state to be set. In these cases, on startup, the driver can not know the hardware state and it is recommended that the driver either:
- Sets the device to a known state on connection
- Throws an until the client software has set the device state for the first time
In both cases the driver should save a local copy of the state which it last set and return this through GetSwitch(Int16) and
Devices are numbered from 0 to MaxSwitch - 1.
This is a Version 2 method.
|If there is a temporary condition that prevents the device value being returned.|
|If id is outside the range 0 to MaxSwitch - 1|
