Hold Flags are used with the peak/bottom hold and top/valley hold functions.
The Hold Flags are used to control the hold execution timing from the Master
and are allocated in the Master using the following data format (2 bytes).
Note A delay may occur between when the Master's power is turned ON until notifi-
cation of the Hold Flag status is sent to the Unit.

Normally, when using a two-point Input Unit, the values for the two inputs are
converted in sequence. The setting can be changed, however, so that unused
inputs are not converted. By reducing the number of conversion points, the
