The Default Timer Preset establishes the time interval (in
milliseconds) during which inputs are frozen while a device is
missing from Bus A AND from Bus B.
This parameter (a Boolean) determines the behavior of a missing
device:
If the parameter is set to 0, the inputs for that device will default to
OFF or 0 after the Default Timer expires.
If the parameter is set to 1, the inputs for that device will be frozen
in their last state until the device is reattached to either Bus A or Bus
B.
This applies to discrete inputs. It is the reference offset between a
discrete input configured on Bus A and the alternate address on Bus
B. For instance, a device configured at %I0001 on Bus A must be
configured at %I (1+DI_OFST) on Bus B. The offset must be in
multiples of 8 (i.e., on a byte boundary).
This applies to analog inputs. It is the reference offset between an
analog input configured on Bus A and the alternate address on Bus
