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
Unit and are allocated in the Master Unit using the following data format
(2 bytes).
Note A delay may occur between when the Master Unit's power is turned ON until
notification of the Hold Flag status is sent to the Slave.

Hold Flag for The hold function is performed for Analog
Input 0 Input 0 while this flag is ON. The hold func-
tion stops and the last value is held when the
flag goes OFF.
Hold Flag for The hold function is performed for Analog
Input 1 Input 1 while this flag is ON. The hold func-

time has lapsed.
Used with the top hold function.
Turns ON when a top is detected,
and turns OFF after the one-shot
time has lapsed.
Turns ON when a disconnection is
detected.
