Summary of the Analog Input Slave Units
Section 6-2
The meaning for each bit is as described below.
Analog Data 1 + Top/Valley
Detection Timing Flags This data pattern consists of Analog Data 1 followed by the Top/Valley Detec-
tion Timing Flags and is allocated in the Master Unit using the following data
format (5 words (10 bytes)).

0 LLx Compara-
tor Result
Flag Low Low Limit
Alarm Flag Turns ON when the value of data
allocated in Analog Data 1 drops
below the Low Low Limit alarm set-
ting.
1 Lx Low Limit Alarm
Flag Turns ON when the value of data
allocated in Analog Data 1 drops
below the Low Limit alarm setting.
2 PSx Normal Flag
(pass signal) Turns ON when none of the alarms
(High High Limit, High Limit, Low
Low Limit, and Low Limit) have been
output.
3 Hx High Limit
Alarm Flag Turns ON when the value of data
allocated in Analog Data 1 exceeds
the High Limit alarm setting.
4 HHx High High Limit
Alarm Flag Turns ON when the value of data
allocated in Analog Data 1 exceeds
the High High Limit alarm setting.
5 V_STx Top/Val-
ley Detec-
tion
Timing
Flags Valley Detec-
tion Timing Flag Turns ON at the timing when a valley
is detected by the top/valley hold
function and becomes 0 (OFF) after
passing of one-shot time.
6 T_STx Top Detection
Timing Flag Turns ON at the timing when a top is
detected by the top/valley hold func-
tion and becomes 0 (OFF) after
passing of one-shot time.
7 BWx Disconnected Line Detec-
tion Flag Turns ON when a disconnection is
detected.
