I/O Data
Analog Data Analog data is used to monitor analog values. Analog input value is allocated
as the default setting, but any one of analog input value, peak value, bottom
value, top value, valley value or rate of change can be selected as allocation
data.
Note The comparator function can be used for the data allocated in Analog Data.
The data format used for allocating data in the Master is shown below. Data is
allocated as two’s complements (4 bytes = 2 words).
Top/Valley Detection
Timing Flags (Shot Status)
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
allocated in the Master (2 bytes/1 word).
