Top/Valley Detection
Timing Flags (Instance
132)
These flags turn ON for the one-shot time when detecting the top or valley for
the top/valley hold function.
These flags are used to time reading the values held as the top and valley val-
ues at the Master. The following data format is used when these flags are allo-
cated in the Master (2 bytes).
The details of each byte are shown in the following table.
Note The one-shot time can be changed. For details, refer to the one-shot time set-
tings for the top/valley hold function.
The following format is used when the Top/Valley Detection Timing Flags are
allocated, starting from the rightmost byte of the Master
Analog Status Flags
(Instance 134)
The Analog Status Flags include allocations for the Comparator Result Flag,
the Top/Valley Detection Timing Flags, and the Off-wire Detection Flags.
These flags are used for detection and monitoring.
The data format used for each byte when these flags are allocated in the Mas-
ter is shown below (4 bytes).

function and then turns OFF
after the one-shot time has
elapsed.
